Hi everyone.
HTC Desire is being found in my country better than other android phones, but I have a serious problem with its bad video recording framerate (15). I tried to download a video sample, and it was really bad as I thought (no offense to the fans ).
My phone's video recording ability is important for me, so please don't give answers like: this is a phone, go get a camcorder, ...
Some people say that it will have HD 720P support in future firmware updates, but I wanna know is there a plan to improve the framerate as well?
Thanks.
As the phone records direct to the SD card I would suggest trying a faster class of card and see if that affects things at all.

the desire already has 720p recording, but keep in mind its limited by its hardware, 1 ghz isnt alot to encode HD and i know the iphone has better HD recording but i think that has somthing to do with its improved gpu, recording at lower resolution is flawless so why not do that?
Galaxy S and iPhone 4 are the first phones that are likely to have the processing power to record 720p with decent framerates. Desire just isn't as powerful, no matter how it's optimized it won't be perfect, ever.
However, even those two phones (probably) don't benefit much in terms of real video quality by just upping the recorded resolution. Trying to fit even a BAD 720p-capable sensor in a phone form factor isn't going to be a reality for a couple years or so, I'd estimate. Right now you get lots of extra pixels but the picture doesn't actually look any better since the sensor is too small to properly capture such high resolution.
It's something like the "megapixel war" that went on (and continues to some extent) between the major camera vendors. There's not more space to use a better sensor, they just make the sensor try to interpret the light better. Now it's phone vendors claiming they can do 720p when in reality the sensors they're using are probably capable of "real" 480i resolution at best.
But you can see the result... take two shots on the phone of your choice, one at 3mp or so and one at the maximum, then try blowing up the 3mp one to the 10mp one's dimensions and compare them side by side. The resized one looks a bit blurry? Now apply a good professional sharpening filter such as Neat Image. Voila, they're all but identical, just one has lots more garbage data in the form of grain where there was none in real life. The sensor is so tiny there's literally just not enough photons hitting it to do anything but interpolate most of the data, even in daytime outdoors.
I know you said you don't want me to say "just buy a camcorder", but honestly that's the only solution if you want an actual image quality difference. An honest camcorder can give you a million times the feature set and record decent audio too.
Maybe check out the Canon HF100... I think that's what it's called. I have the previous year's model and it's outstanding value. Record true 1080p @ 30fps, and it's so clear you can capture individual frames from it and it looks better than any cameraphone. Takes competent stills too, and I think the most recent model has 20x optical zoom. It's like... 25% larger than an empty toilet paper roll and a little more squarish.
So do you recommend setting to 480?
Thank you guys.
I bought a Google-HTC nexus one today D). I had to buy a used cell phone because of the android phone shortage in my country, and I had to buy it today, so I wasn't able to read any of your posts; but some interesting comments have been posted:

You mean there is a video recording mode for desire, which records in lower resolution, but gives better framerates?
If so, desire would have been a flawless choice for me! Why isn't this mentioned anywhere?

Very interesting ideas, thank you.
I have noticed the difference between true 720P videos and the "claimed" ones which are being recorded by cell phones, and, frankly, the difference is obvious.
But still, if you watch the video samples from desire and some competitors (from GSMArena or somewhere), you will confirm that there's a huge difference, which is not being caused by the low resolution, but by the poor framerate in desire.
Desire's video sample is disappointing...
But if it's possible to record in lower resolution and better framerate, then desire would have been a better choice than a second hand nexus one.
Hardware not capable? 1Ghz not fast enough?

IPhone uses its GPU, that's why it performs so well. Guess it's a driver issue. If the desire were to utilize the GPU, the results would be far better.
iPhone and Galaxy S share the same CPU/GPU chip, and as you say, yes it probably leverages the GPU to help encode the data more efficiently. Even if not, it's a more efficient chip which doesn't just mean it's smaller and uses less battery, but it's actually more powerful despite running at the same clock speed.
For example, I had an experience when I was upgrading my computer last year, going from a 65nm CPU to a 45nm CPU with identical architecture, cache, etc. Running at the same clock speed I get ~20% or more of a performance boost just due to the better efficiency.
I can't say how well that carries over to this situation since I'm sure there are more improvements in the transition from "snapdragon" to "hummingbird" than just the newer manufacturing process and more powerful GPU, but you can be sure the CPU gains a significant speed advantage from the lower node even before whatever other enhancements have been made.
"Hardware not capable? 1Ghz not fast enough?
Nexus one 720p @27fps!!!"
I'm not even going to look. 27 FPS isn't any kind of standard and if indeed that framerate is being achieved it's because there is extremely good lighting. Please introduce me to the world you live in where everyone and everything is always in ideal studio lighting... Aside from that I know without clicking the link that it will be terrible-looking.
"But if it's possible to record in lower resolution and better framerate, then desire would have been a better choice than a second hand nexus one."
I don't mean to belittle you but doesn't it go without saying that there is a lower-resolution video mode available when 720p is only just being unlocked in the most recent firmware? Whatever the case, N1 and Desire have identical hardware, if anything you might have a screen you like better than if you bought a Desire today.
Anyway, yes in my opinion you'd normally want to record at a lower resolution. I haven't done a thorough quality comparison but I'd guess you're not going to get much benefit from going above 320x240 for video. The truth is harsh, isn't it? Probably no harm in using the highest image size but it's not going to deliver miracles, especially considering the shutter lag and lack of any kind of image stabilization system.
But on the upside, your videos will have a smaller filesize, the framerate will stay consistent (at least if there is adequate lighting), and as I said earlier there is absolutely no real-world quality difference except that you'll get less battery usage and video noise when recording and playing back lower-resolution video.
Keep in mind, I bought a Desire and I love it. I even think the camera and video is fine. Just keep your expectations reasonable and realize that you need an actual camera to take good pictures/video. It's for Youtube, Facebook, and that kind of thing, not wedding photos.
Canon HF100 (IIRC) is a solid prosumer choice, or if you want something more compact but still versatile you might look at the Sony DSC-TX5, which is very durable and even waterproof to boot. It was just replaced with a newer (but not significantly different) version, so you can get it pretty cheap too. It offers quite good still and video quality (REAL 720p) considering it's like 15mm thick and even has some voodoo real 5x optical zoom system despite not having a moving lens on the front.
This thread's piqued my curiosity a bit, I'm going to try to do a semi-scientific study to determine what the best settings are for the camera.
I can't say exactly how you'll have to configure your new N1 since I'm using the Sense camera app, but you can probably still have an improvement by trying to modify settings in a similar way.
This is very preliminary and I don't have daylight to work with, I'll get into it more tomorrow, but so far:
Contrast is best at its default setting, 0. I'd prefer a -0.5 but no such option exists.
Saturation should be reduced to -1, this will help lessen the strength of noise and also gives somewhat more realistic color.
Sharpness should be reduced to -1, this again will help reduce noise and eliminates the majority of the sharpening artifacts. Going down to -2 helps a bit more but the loss of detail probably isn't worth it.
Brightness should be left at 0, it operates in mysterious ways and doesn't seem to be very helpful regardless of how it's set.
The ideal video capture resolution is 640x480. 320x240 doesn't appear to bring a framerate improvement so there's not really much sense unless you're limited by storage. All capture sizes besides 320x240 and 640x480 operate by simply cropping the image and offer no positive effects that I can see. 720p may add a superficial amount of detail but at the cost of an unsteady framerate and much greater encoding/decoding load (1280x720 vs 640x480, or 921,600 pixels per frame vs 307,200).
Similarly, taking widescreen stills simply crops the top and bottom and results in no quality difference to the part of the full frame that's actually recorded. You're probably best off recording in the sensor's native 4:3 aspect ratio and then cropping them to your taste on your home computer.
The ideal video capture codec is MPEG4 - H.264 offers a nice reduction in filesize but uses too low of a bitrate, resulting in worse quality during fast movement. It is also more work to encode and decode, hurting your battery life.
Obviously don't use zoom for any reason since it's just cropping and resizing with speed as the only consideration. You'll get much better results doing the same thing on your home computer.
Due to the low sensor quality, there's not a whole lot of difference between 5 and 3 megapixel shots, but there's no harm in going with 5mp. The biggest difference is the filesize. Taking a picture of the same subject, my 5mp shots ranged from 2.96mb to 2.38mb, while the 3mp ones were 1.22mb to 0.76mb.
I'd like to revise my earlier statement that the processor isn't capable of encoding 720p30 in realtime. It's now my opinion that the problem is just the camera firmware trying to make sense of the idea that you're asking it to pull usable pixel data for a 1280x720 frame, 30 times a second, from such a tiny sensor. To compensate for the lack of light information, it's forced to reduce the framerate or else the image will turn into a mess of noise. It's probably being a bit too conservative, but not by a lot. The fault lies with the sensor, not the CPU... I think.
Finally, *something* I did seemed to significantly reduce the framerate, or rather, the quality of recording high-motion video. This might be something peculiar to the rom I'm running, or it could be completely in my head, but I think I changed something when I was messing with the various settings and it had a noticeable negative effect.
It's late here now so I'll pick up in the morning but my current wild guesses are:
-Capturing full-frame is more difficult than capturing cropped widescreen, or vice-versa?
-Face detection processing adds too much latency to the recording?
-Flicker reduction should be taken off auto for best performance?
-Custom filtering settings (brightness/sharpness, etc) slow recording down?
-How the camera was focused reduced/increased the encoding difficulty?
-Sharpness settings increased/decreased the amount of frame data needing to be encoded?
-...Or I screwed something up in SetCPU? No... I don't... think so... but it's pretty late. Hmm...
I'll pick up tomorrow. Someone's probably already figured out the perfect settings but I'm pro at being redundant.
The 480p is flawless?
Come on ... It is OK-ish, but not flawless. Especially indoor, even with good lighting still mediocre.
Multimedia is one of the weakest in Android, hopefully Gingerbread will correct this.

You could try switching to 800 ISO in settings camera mode, then switch back to camcorder mode. I noticed a considerable fps boost even in low light conditions.

Before buying nexus one, I checked out desire's specifications in its GSMArena's page, and it said:
Video: Yes, WVGA (800x480 pixels) @ 15fps
So I thought its the only video recording mode that the phone has (I'm not experienced with modern phones). I wasn't expecting a cell phone to have different video capture modes like a digicam/camcorder.
Then, I downloaded a video sample that was being recorded in daylight, but was really disappointing, and the framerate was exactly 15.
And, in my experince, if you buy products, specially high tech products like modern phones relying on the informations that (you think) "go without saying" you're going to be serioulsly punished by your mistakes.
You can only rely on facts...
By the way, thanks for the experiments.
There is some work done in the developement section to optimize HTC camera 720p framerate. A guy obtained 29fps in good lighting (not perfect) but he's still working on it. Funny part is that he blew his desire while testing it.
Check this:
http://www.youtube.com/watch?v=ynB0M9NeVCE
Regarding the current state, a good sd card can help with the occasional stuttering, or if you can live with AOSP roms, you probably will get a couple fps more. Otherwise you are confined to good lighting to have something on the good side of 20fps.
some examples from my phone:

Wow, that's really good tip!
when you increase your ISO your picture quality gets poor.
it helps to make videos faster and smooth but with no quality.
Ive just ordered my new Micro Sd card class 10 card... let it come and i'll let you know if something good happens...

I'll disagree about poor quality - it just gets a little worse, even in indoor lightning, but you get an acceptable video, compared to the "very creepy slide show" in auto-ISO mode.
Besides the average framerate, which is probably more due to the lens and partially to the software, isn't the stuttering problem caused by an aggressive datarate when writing to the sd ? If you compare cyanogen 720p recording to HTC, quality isn't really different, but the data-rate codec probably is, and that's why even with a class 2 you avoid stuttering in cyanogen (OD and Defrost too).
Sorry if I up this thread, I found a micro sd card A-Data class 6 with good price, this micro SD can fix the problem recording video a 720p?
Thanks to all
Hello!
I got some tech questions about desire z's gpu...Is it true that although the polygon draw/sec is great, we only have 240M pixels/sec fill rate?This is not fast at all..sgs carries 1.000M and even the lousy iphone4 has 500..droids x and 2 also have over double of ours..I cannot find any sort of technical sheet about adreno's stats..
Also , do anyone know if fill rate is affected by overclocking the cpu?I know that overclocking cpu indirectly affects fps gain but i would like to know if that is the case for fill rate as well...
Could this be the reason our 720p recordings are jerky and not 30fps?
I couldnt find details on the fill rate but I know for a fact that galaxy s phones still have the better gpu. Our gpu still hasnt caught up even though its improved from the adreno 200.
The weird thing is that its us, that are behind the curve, even with brand new phones,which happens because for some reason qualcomm is being super secretive about their chips specs...and the difference is really obvious..just open the camcorder on an iphone 4 or a droid 2 and try moving the phone camera around very fast, while looking at the screen.the picture follows at almos real time speed..on g2 it simply blurrs the screen till you stop moving the camera.
Hello,
Im looking to upgrade my Nexus 5 and ive been going through lots and lots of reviews, videos, pictures of many of the new phones out right now. Z5, S6, Nexus 5X.
I really like the Nexus 5X despite some of it shortcomings but one thing i REALLY have a hard time accepting is how shaky the picture is when recording video compared to iphone 6s, Sony Z5 and others.
Here is a video showing it against the Moto X pure:
https://www.youtube.com/watch?v=l_zth08zFLw
The Nexus 5x i horrible Is that something we will just have to accept because it lacks OIS or is it possible to fix software wise in a camera update or using a 3rd party camera app. I must say that in its current form its unusable.
Regards
Jacob
indeed it is shaky...
haven't tried it but this one has video stabilization - https://play.google.com/store/apps/details?id=net.sourceforge.opencamera
Maybe someone with a nexus 5x could try opencamera to record a video and post the result?
Yeah I was hoping 1080p would at least get decent software stability. It has enough pixels for it. ?
Sent from my Sprint Galaxy S5.
Does anyone know? Anyone tried opencamera?
Just my $.02. It was my understanding from the Launch event that it doesn't have image stabilization. Something about how it didn't need it with the upgraded light gathering capability of the camera.
The Moto X pure doesn't have OIS either, it's done in software
I'll just splurge for a gimbal. LOL

Just tried it and it seems decent. Good thing is that OpenCamera properly implements the sensor orientation detection, so the preview and resulting files are correct. It has experimental support for Camera 2 API, which needs to be enabled in order to expose the EIS setting.
At high resolution (4k), there's significant lag that's recorded in the videos with the EIS enabled. Google did say the 808 couldn't handle it; maybe they weren't just blowing smoke?
At 1080p, it seems to help reduce the shakiness by a fair amount; it's no OIS replacement for sure, but I'd say better than not having anything.
Funny how google said larger pixels negated the need for OIS. Did anyone really believe them? Did HTC not try the super mega sized pixels before?

From pics I saw it does fine without OIS. But videos would have benefited. And yes they coined it as "ultra-pixels".

OIS is only really of benefit for photos at shutter speeds less than 1/60th second, unless you have a zoom lens, where it is helpful at higher shutter speeds, as the more you are zoomed, the more amplified any body shake is. For smartphones with their wide angle view, camera shake is not too much of a problem for most typical situations, and any daytime scene OIS is completely pointless as the shutter speed is plenty high enough to freeze out any camera shake. The larger pixels help as the ISO can be higher without too much noise meaning a faster shutter speed can be used.
For video the situation is different as images are taken over time, so it's the movement in camera position between each picture that needs to smoothed, although the fashion these days on most documentaries and TV shows is to deliberately shake the camera around until it's a nauseating mess with whip zooms into the mix Still it's a good indicator I find for knowing the program is trash and not worth watching :victory:
OIS in smart phones helps a little with video, but the tiny lens optics and limited movement means they don't do nearly as well as a dedicated camcorder with OIS, which gives some amazing results. The link to the stablised 5X video is using a $300 device, so if anyone is that serious about their smart phone video, then for that money we might as well take a much bigger step in image quality and convenience and features and get a dedicated camcorder.
The elephant in the room with the Nexus 6P is EIS, this is the poor mans image stabilizer, yes it does help stabilize the video to a certain degree, but to do this it has to crop the image. It appears to be doing this the cheap way in software (hence needing the powerful chip), taking a 1080P video, then zooming into so it can have a window of view to pan around in, this means the resulting video has less resolution, see the clips here https://youtu.be/HV4rcFuUlUc?t=246 and compare the detail between the two, there is a drop in resolution on the 6P. Better EIS systems capture a larger image at the sensor, then would track and pan a 1920x1080 window across it so no resolution drop, but that requires more low level work with the camera hardware and dedicated chips to do a good job.
Record a 1080P video with the 5X, upload to YouTube and get it to apply stabilization and it will do the same thing, may even turn out better than the 6P EIS as it doesn't need to be done in real time so a bit more care can be taken.
Will the 6P stabilize 4K video? I somehow doubt it has the power to do that, so for 4K it's an even playing field between the two.

Hmm, aren't those phones using the much higher resolution of the sensor (at least about 4k) to stabilize the video by changing the captured frame on the sensor corresponding to the phones movement? At least i thought that's the reasoning why this works only up to 1080p (which would be preserved, in that case).
I think this could be quite useful for the next Nexus http://techcrunch.com/2015/01/09/imint-wants-to-bring-real-time-video-stabilization-to-android/
Title. Thinking of buying the phone but I was wondering why run 1080p at normal usage when they can do 1440p? Don't they the same aspect ratio? Does any of you think it's possible to sort of change the normal screen resolution to 1440p?

My guess would be performance and it may be easier for the upscaler if it's a 2:1 ratio
The Nexus 6p has no problems running 1440p on a s810 snap dragon, bench mark tests beats the Sony Z5P consistently.
Mostly because it makes no difference in the user experience, but makes the SoC constantly process a lot more pixels which would contribute to the heating issues and shorten battery life.
This 4K thing is purely for brag, and Sony knows it. Wait until mobile VR grows bigger and there will be all kinds of resolution mods then, when it matters.
For now, even if you got short hands and the phone screen is ~20cm from your eyes, you cant tell the difference with a 20/20 vision.( tested )
Alright guys, here's the deal. The Note 7 was an awesome phone, i had to give it back, not cool, etc...
But now that I've seen what GearVR is, and more importantly, what it COULD be with a 4k Resolution, (without the screen-door effect), a Non-4k Note is a deal breaker for me.
If Samsung doesn't deliver 4k, I will get the next phone with a 4k Screen, (not the old Sony one but a new one which supports Daydream).
What's your take on this?
It's also got to be able to do VR without going nuclear. It's hot enough in those goggles without the phone feeling like the surface of the sun.

considering none of the VR headsets even matched the res of the Note I don't see 4k as being needed, the problem came from the low refresh rate of the screen as it is far more important.
if you want a better VR experience you should be asking for at least a 90hz screen (matching the dedicated headsets) or higher. also the higher the res the lower the frame rate and the lower the refresh rate will be to compensate for the lower frame rates leading to far more tearing and the same horrid lined effect the note had in the gearVR.
so yep had a taste of VR but on phones it is largely hampered by screens designed to save battery life, increasing screen res is just the go to assumption most people make, when the dedicated head sets run at a lower screen res but higher refresh rate giving better quality.

What are you talking about? You know the lens on the gear VR is just a lens right? There is no "resolution" to speak of. A 4k screen on a smartphone would definitely improve viewing on the gear vr. 2x in fact.

Completely agree. 2k is simply not enough. 4k is not enough either, but it would be a bit better. I think we are really going to need about 4k per eye in order for it to become truly fantastic. Maybe 8k per eye. So we are talking something like 7680x4320 or even 15360x4320. I doubt that smartphones are going to be the vehicle to deliver this in future.
But for now, 4k would be nice.
the dedicated and phone headsets are identical in principle, they both place OLED screens and the gubbings behind a lense, the only difference is in a dedicated headset you can't remove the screen and other bits.
however the Oculus Rift and Vive both have better picture quality than the phone alternatives, both are only running 2 screens that give a combined screen res similar to a 1080 screen, the difference comes in the refresh rate, the Rift and Vive both run at 90hz+ meaning they can push out smoother images and have less chance of having artifacting and interlacing problems, something the phones have by the bucket load, move fast with a phone and you will see lines miss match all over the image, going to 4K or above wouldn't fix this problem if anything it would be likely to make it worse as there is less chance you would even achieve 60fps leading to even more stutter and artifacting, the 90fps+ of the dedicated headsets still isn't perfect but it's a million times better on smoothness and artifacting, this is because if you want a better picture in VR frame rate and refresh rates are far more important than the screen res as even under a lense the PPI on the likes of the Pixel and Note 7 is still that high it is of little consequence, it's the reason the dedicated headsets went with a lower screen res in favour of refresh rates.

I honestly hope it is years before they even think about a 4K screen. Our processors can barely push 2K at this point and battery life is pretty terrible currently compared to 1080p phones such as the iPhone 7. It's not worth it for such a niche feature. I mean, the Rift and Vive are not even at that resolution because desktop PCs can barely push it.

however the Oculus Rift and Vive both have better picture quality than the phone alternatives, both are only running 2 screens that give a combined screen res similar to a 1080 screen, the difference comes in the refresh rate, the Rift and Vive both run at 90hz+ meaning they can push out smoother images and have less chance of having artifacting and interlacing problems, something the phones have by the bucket load, move fast with a phone and you will see lines miss match all over the image, going to 4K or above wouldn't fix this problem if anything it would be likely to make it worse as there is less chance you would even achieve 60fps leading to even more stutter and artifacting, the 90fps+ of the dedicated headsets still isn't perfect but it's a million times better on smoothness and artifacting, this is because if you want a better picture in VR frame rate and refresh rates are far more important than the screen res as even under a lense the PPI on the likes of the Pixel and Note 7 is still that high it is of little consequence, it's the reason the dedicated headsets went with a lower screen res in favour of refresh rates.

I'm sure that's all true, but in any event, with a phone with a 2k screen the pixel density is not high enough and it won't be at 4k either. With 2k each eye is getting an image something like 1,000 pixels across (the two VR windows don't use the full screen width, so less than half of 2560 each), which for a virtual image which is bigger than even the very biggest TV screens (100"+) this is not enough pixels and the image is visibly (very badly) pixellated.
I am sure refresh rate matters too, but we really need very high pixel density and fast refresh (and low latency and wide viewing angles) for what in the end will be "perfect" VR.
the HTC Vive has a better picture each eye has a screen at 1080x1200 giving a total resolution of 2160x1200.
the Note 7 has 2560x1440 meaning each eye is getting 1280x1440.
so the Note 7 is a noticeably higher screen res than the dedicated VR headsets, the dedicated headsets however give a better picture, both use OLED screens, the Note 7 has a higher screen res, but the Vive has a refresh rate of 90hz, most phones are lucky if they do 60hz quite often it is considerably lower to save on battery, so by your logic the Note 7 with it's higher screen res would be noticeably better quality than the Vive, however the Vive is noticeably better than the Note on picture quality and that is purely due to the refresh rate difference as it gives a smoother image and also stops nearly all the delacing issues the Note and other phones have despite being considerably higher screen res.
Yes. If Samsung doesn't announce Note8 soon, I might go with sony xperia new phone, whose name I still keep forgetting. To be anounced at MWC and with 4k screen.

For gaming, I agree that the Note 8 with a 4k Screen won't be much Help. But I never really enjoyed VR for gaming, it's more like a "side fun activity". But to watch video content, a 4K Display Note with an 10nm processor would be more than enough to remove the screen door effect, and give the ability to watch awesome 180/360 content, and 3D movies on a huge VR theatre.
May I remind you that VR for gaming is failing generally right now. But for some shady reason VR for videos is not... (go figure... xD )
