720p recording at 30fps

can i get 720p recording at 30fps on desire
i m tired of this **** never gives above 10-15 fps
in day time in bright light it might give 20-24fps....but still audio is out of sync and **** like tht
i know desire reduces frame rate to prevent picture from turning grainyin low light especially at night.
even under bright tubelights i get 10fps nothing more than that.
also light constantly keeps on flickering...the light sensors further reduce the frame rate
bad thing is that even after 1.5 yrs after the release of desire....HTC didnt do anything to fix this in the gingerbread
i have tried stuff like setting ISO to 800 and increasing exposure levels to increase fps but still its not good enough
some of th expert developers out here have been able to do the impossible and bring stuff on the desire which is unbelievable...
but i seem to find no one who has been able to fix the camera on desire...
plz guys look into this....
can the camera app be tweaked to make it record at constant 30fps...
can the variable fps be fixed .
i dont care if quality drops or not....coz who cares if u get quality which is not watching
i dont mind grainy images but i want 30fps....can the developers do some tweaking/??coz i know the hardware is there to handle

do this:
-change the desire camera with a better one
-change the desire gpu with a better one
-write the correct drivers and kernel to handle the news parts
and thats it...
or just keep in mind this phone is not capable to make great hd video.

so u say its a hardware problem????
also is the hardware on other HTC phones like sensation and desire S the same???
I heard these phones also suffer from same bad fps in low light problem

Desire S - has Newer SoC, Single 1Ghz CPU, but Adreno 205 GPU - it makes very good 720p videos, but with lower FPS (but not below 23 in low light) - My roommate has it and it is miles better, than my Desire.
The Sensation has even newer SoC - Dual-core 1.2 GHz and Adreno 220 GPU - I tested my collegues device, and it had no struggles even with 1080p in low light.

that you have an hardware problem is my opinion, too

Like everyone with this device.

so is it worth upgrading???
i am looking forward to HTC amaze...
I hope it doesnt suffer from lower fps problem
(also fps not lower than 23fps in low light does not sound bad)
now i am confused whether I should go for droid RAZR,galaxy S2 or galaxy nexus...
i liked HTC for HTC sense...now with all these devices receiving Ice cream sandwich....
i am thinking UI will be same for all....so confused

You can try the recording on cyanogenmod 7. I think the 720p framerate is a bit better.

[Q] Why is the refresh rate on the Note 2 58hz?

Hello folks,
I have had my Note 2 for a couple of days now and almost immediately noticed something strange. There is a VERY subtle flickering of the white and light grey areas of the screen. A very high frequency flicker, almost like I can see the refresh rate of the screen. My initial suspicion was that the refresh rate was lower than 60hz. So, I downloaded the app called Android System Info, and sure enough, under display, it was being reported that the refresh rate of the screen is 58hz. I got another friend with a Note 2 to confirm the same thing. My GS3 reports 60hz, and so does my friends HTC One S. So my question is, why is the refresh rate on the Note 2 not 60hz? Is this an intrinsic hardware limitation? Or can this be changed with software? My eyes can definitely notice the 2 less frames per second, I was using a GS3 since June, and switching to the Note, I immediately noticed the refresh rate was lower. Why? This is very strange to me. There are many videos on YouTube with the Note 2 and GS3 on the screen at the same time, and sometimes there is banding interference on one phone and not the other, meaning obviously the phones are running different refresh rates. Now I know the Note 2 refresh rate is lower, why? And is there anyway to change it with software?
Thanks much!

first, i think u should get yr note2 to warranty,
second, u sure yr eyes can differentiate 58hz and 60hz......?

It is EXTREMELY subtle, almost a non issue, so I doubt warranty will even say anything is wrong. I can notice it on all the demo models i've seen, so I doubt it has anything to do with my phone.
I have confirmed on 3 different Note 2s, the reported refresh rate in the app 'Android System Info' is 58hz. While all other phones I have used report 60hz.
I just find this so strange that maybe someone has a great explanation as to why this is the case. And maybe someone can dig deeper than I can and figure out if this is in the OS or an intrinsically hardware thing. I wish I had the email of a Samsung engineer who worked on the design of this phone, would love their take on why this is the case. 58hz is just such a strange refresh rate.

you are the man, mate, my eyes cant even differentiate 50 and 60 Hz, for all my note2 experience, i cant see any unusual on the screen.
But for the 58hz issue, i think its not quite a strange thing for me, it reminds me when i was using CRT monitor(or early lcd?), it always can set the refresh rate to 58hz or 60hz, but it might like u say a hardware or driver problem, hope u can contact with samsung engineer and tell us the answer

I suppose the app might be reading the values of somewhere not actually measuring it or something ! Correct me if am wrong .

this is interesting. i also notice a subtle flicker of the screen. it's annoying in some lighting. i don't notice it on other phones.. it's definitely seems like the refresh rate is a bit slower than it should be.

The refresh rate is correlated with the resolution and the main base clock which feeds the display controller, in this case 1280 * 720 * 58Hz = ~54Mhz plus some margins for which are too long to describe, which gives them a target frequency of about 54MHz for a 16 divider of the 880MHz base clock. That's the main reason of the 58 vs 60 Hz difference.
But the reason you're seeing flickering might be completely unrelated to that and caused by some odd much lower timings in the display settings. Maybe a developer with the device could test it out by changing them.

Thanks for that information, it's great technical info I've been looking for. So it's basically a ratio/multiplier of some clock speed in the hardware. But now my question is, why would the Note 2 be any different than a GS3? I would think they have relatively the same hardware, and resolution on both screens is the same, so why would the refresh rates differ? Just seems to me that 58hz is not an ideal refresh rate. I mean, the main reason there is a trend towards 120hz TVs these days is because both movies (24 fps) and TV (30 fps) are evenly divisible into 120. Whereas with a 60hz TV, there is a remainder on 24, so movies do not interpolate as smoothly. With 58hz, no recorded content I can think of divides evenly into it, always making interpolation less smooth. Again, in my mind, 58hz is just silly, why not just give me the extra 2hz!! Doesn't make sense to me.
Final question. Would there be any way with software to change the refresh rate? Or is this set in stone at the hardware level?

I have an issue with this as well - I'm getting either fairly heavy frame skipping in any 8 or 16 bit emulator with frame skipping set to auto, or sound skipping with frame skipping turned off. I suspect this is because of the odd refresh rate with the app expecting 60hz and only running at 58 in reality, causing either the video or audio to run out of sync and needing to skip the two frames here and there to catch up. If the emulators could slow down the audio speed to match the slower video speed, it wouldn't be an issue.... but this shouldn't be the problem of the emu authors.
This happens with no other applications installed on a brand new phone. I've also installed clean rom and perseus kernel, no change. Power settings are all off, nothing is hitting my CPU to cause the frameskipping and it's very consistent, which leans towards the refresh rate causing the issues. Anyone know anything more about this? What a pain...

I am a traffic cop and I can definitely tell the difference between a car going 58mph and one going 60mph.

I'm a noob and I don't know what "stuttering" is
But seriously, it's not like a mobile device should be able to emulate another system anyway, am i rite? Just use it for phone calls and internet browsing...

i think the reason why the refresh rate between gs3 and note2 is different due to both are using different lcd even though some of the hardware is the same.
even though the diff is small but it still incur some major hiccup where the frame skip especially with project butter where they keep the ui at 60fps.
maybe we can email to samsung engineer and they can take a look at it.

[Q] Low Video Rec frame rates and bit rates.

Having frame rate issues with recorded video capturing at only 20fps in 1080 mode, 21fps in 720 mode and 23fps in 480 mode using the back camera. In 1080 and 720 there is constant freezing and missing frames. Using the latest kitkat build 4.4.2 (KOT49h) since day one so maybe there is a bug with the current build as i don't see anyone else have this issue online.
I have not downloaded any apps since purchasing the device a few days ago, no apps running in the background and using the camera when the device has just been switched on.
I also noticed the bit rate is low for 1080 at around 8500 in comparison to an untouched sample i downloaded from another user that is recording at 12733 at 29fps but i think this user was still on the previous kitkat build.
The front facing camera recording is of smoother quality but only records at 25fps in both resolutions on offer.
I have also emailed Asus and the only response i have received is that in low light conditions the fps will drop. The recordings have all been done in bright perfect blue sky conditions so maybe i have a defective light sensor that is wrongly dropping the frame rates to maintain visual quality.
Just wondering if anyone here is using the same KitKat build and can tell me what frame rates and bit rates their recordings are at so that i can determine if it is due to the new kit kat version or it is hardware related.
Online articles have suggested the current KitKat "KOT49H" has caused significant fps drops in video playback and game playback but not sure if this same issue can be stretched to include video recording fps also.
Thanks in advance,
Jeff

HTC 10 Manual Video MOD?

Hi i loved LG G4 and that it had LG V10 camera ported to it.
Now i understand that different brand and all but is there a way to port LG V10 camera to HTC phone?
Im mainly looking at manual exposure in video mode because even after all these years HTC video recording is terrible because of framerate.
Whenever i record video in lowish light i get like 20 fps video looks terrible and laggy even tho sensor on this phone is big and can do stable 30fps in low light with a little higher iso because i also have LG V10 with smaller sensor and higher resolution which means much smaller pixel and in manual mode in same scene i put video exposure time at 1/30th or even 1/60th with iso at 600 and i get little noise while being buttery smooth.
Now this has been issue with HTC from OG days and is there a mod or port that i dont know about that can let me control exposure in video mode and i dont mind separate app for that since im using gcam for photos and get some of the best pictures ive ever seen on smartphone,even compared to latest smartphones its in top 3 definitely.
Now back to video,ive seen snapdragon camera and other,none of them does anything to video framerate.
Is there a way to set lowest exposure to 1/30th so that phone does not drop framerate do raise exposure and lower iso.
I personally dont mind grainy video in lower light but man recording campfire i dont need nightvision but for some reason phone tries so hard that it blows highlights and gets laggy as hell.
Some config mods,api mods,apk mods anything to adress this issue,i would be alfa tester for some mods if anyone has time to tinker with it,im more of hardware guy,repairing phones and modding cooling,thermal paste and pads mod,etc.
Software? Not my kind of skill.
So if someone else has some advice or existing mod i havent seen yet let me know i would gladly try it.
Sorry for typos or mistakes typing this on a phone without auto correction
Cheers and thanks in advance

Highly doubt anyone is willing to put in the work to port an LG camera app at this stage of the 10 (2015 flagship) but I cannot speak for others.
I also don't really use my camera outside normal shots so I don't have good experience with vid framerate, etc.
I will suggest that you try out the Google camera ports if you haven't already.

I have tried gcam for video but its terrible compared to stock,in gcam video recording i get stuttering an what not.
I know old phone custom development is over.
Also how it that there is no some universal camera that can use those core features available on other phones.
Unless LG uses some sort of asic for camera but i doubt it since LG V10 camera can be ported on other LG phones like G4.

Sorry wish could help more.
Gcam is the best ull see for non-sense ROMs.
There's many ports and settings you've played with that? Like changing from nexus to pixel.

I have tried other mods and setting but in any case when i pan camera its stuttery on gcam and didnt try gcam in low light tho.
Only thing i need basically is ti limit minimum fps to 30 because it drops to 20 or so in low light and panning from lets say bright window to darker room suddenly video looks blurry and smeared because of shutter speed.
Im on custom rom Leedroid using Elementalx kernel not overcloked or underclocked.
Any ideas what to try,its not professional camera i know and i dont shoot movies with infact i dont shoot maybe 2 times a week short video and i eork ina gaming club where light is dimm and sometimes some promo video needs to be recorded for social media and it looks terrible and overexposed even tho ist dark cause camera is launching shutter speed into the sky to make up for low light.
I used professional camera in full manual mode to record conferences and things like that and shutter speed half of frame time like 30 fps max exposure 1/30th but you put it to 1/60th to make video look smooth as,and only change ISO and aperture to change how bright shot is.
In any case any kernel api config profilesxml file to change that because i have LG V10 and with that things manual camera i can do wonders for video cause at the end of the day best camera is the one that you have with you all the time,amarite?
Thanks for the answer tho u will try some other ports and test just in case i missed something.
I only used apk ports,do i need flashable zip for better and more stable ports?
Any android camera experts out there feel free to add some smart teach heavy solutions.
Thanks in advance.
Cheers

Looking now at gcam video it is less smeary but when recording starts it hicups every second or so.
Any setting to change in dev settings of camera?
And sorry for typos in ally posts i type on the go without autocorrect,what can i say i live my life dangerously

Not the guy to ask.
Maybe one of these threads after a quick search.
Could be better threads, but thb I've probably used this camera like 30 times max since May/2015 lol so safe to say I don't take many pictures or vie.
Hope this helps.

How to set 25fps?

So just got the phone a couple days ago... And im trying to figure out why im stuck in NTSC frame rates.
Im from the UK so obviously i prefer the look of 25FPS and when i do content I work in 25 fps.
It really seems strange that the cameras are arbitrarily locked to US frame rates.
Is there anyway to get 25fps?

Yes can be annoying. Cannot change it in the stock camera APP AFAIK. But other apps like Open Camera for example will allow you to set the FPS to 25fps.
It's likely just not as important as it once was... Unless you are specifically playing back on a older interlaced television set, than the chances are that item you are watching the video back on will support it regardless..
i.e Most phone, laptop and PC screens are running at 60hz, and most TV's will handle 24/25/30 fps intervals without issues these days.
Most people are uploading to youtube or online where by 30/60fps make more sense. 25fps is a leftover from the interlaced broadcast TV days. So the only difference it would make is if you shoot at 30fps and then need to broadcast it at 25fps, in which case you would have 3:2 pulldown.
The standard camera app does allow flicker/banding to be set to 50hz/60hz/Auto thus not to have strobing light issues.
But is there a specific reason you want to shoot 25fps and not 24/30/60?

Having worked in video production for much of my working life, I cant say i fully agree. While sure 30fps is common thats only because most content on youtube is from the americas where 30fps was common
It isnt just a hang on from the interlaced days either. A lot of american shows were actually shot on film at 24 and 25fps and then upsampled to 29.97 fps (or there abouts) 24 and 25fps have a more filmic and natural flow than 30/60.
Even today nearly all dramas and filmic shows in america are filmed at 24 and 25fps. With only soaps and news hanging onto 30fps.
Ive also tried open camera, even though the "option" is there, when i watch the footage it comes back at 30fps.
So its like its baked into the hardware encoder. Its really stupid though. Its not like its a limitation of hardware, not being capable of producing that frame rate because its too complex... Its as if just a config option or api is missing.

I'm from Australia where we also use PAL25FPS, because of 50hz electricity same as you in the UK, but any PC screen or monitor or phone for the last however many decades default is 60hz. Which is why 30/60/120fps makes more sense all around the world.
If YouTube was a British TV program being broadcast on TV, than 25fps would make more sense. But because it's being viewed on monitors, phones, laptops, tablets etc, than 30fps ensures no extra/interpolated/missed frames etc.

Motion pictures have always been shot at 24fps, but TV in PAL countries has indeed been shot at 25fps, while US (NTSC) TV shows are shot @ 30fps.

Ahh, I didn't actually test it, I just remember the setting... GCAM ports will definitely let you shoot [email protected] (as well as 30/60).

I agree the option would be good. But at the same time it's likely not as important as it once was. Many years ago I required 25fps for broadcast TV, but these days it's simply not required. I cannot really see a use case where it matters anymore.
It really is a leftover from interlaced fields, and now days screens are capable of progressive scan.
If you are intending on shooting for broadcast TV with this phone (which seems odd) you no doubt would be editing in post, and thus would convert the 24/30/60fps footage to match your 25fps timeline in post, which would automatically do a 3:2 pulldown or pullup to convert the frames anyway.
If they did offer 25fps, there would be lots of complaints from people wondering why their footage is stuttering and jumping, when played back on their phone, PC, Chromecast, Youtube etc... Which I think is why they don't like to offer it.

Sadly even the best 3:2 pulldown can cause ghosting and artifacts, but I also plan to do some VFX as well, so for things like tracking thats a real killer...
Also im sorry youre wrong many shows in america (assuming they expect to sell internationally) always shoot at 25. Startrek for instance was shot at 25fps on 35mm.
And also when rendering out FX sequences, that extra 5 frames per second really add up.
Id rather keep to 25 for the aesthetics, and the ease of workflow.
I wonder if the framerate is something baked into the firmware of the camera hardware.
