Video Recording quality issues

I usually record videos using my Galaxy Nexus in 720p mode, because 1080p takes up a huge space and my internet is too slow for it..
When I play back the videos that I recorded, it looks so beautiful on the galaxy nexus. But when its on youtube (directly uploaded from the phone), my god! The quality is crap!
Here is the video
http://youtu.be/588xh372ZvU?hd=1 (Uploaded Directly from the YouTube app via WiFi)
http://youtu.be/RbgYReOEoO4?hd=1 (Uploaded from a computer to YouTube.com)
I have done absolutely NO edits or compressions on these videos, and they still looks pixelated! I think even my old HTC HD2 480p camera is better than this..
What can I do (except for going into 1080p mode) to make my video quality better?

Looks fine to me.
Try to stop zooming in and don't make many sudden movements as those cause it to have to focus again.
Also, it is always possible that YouTube is just decreasing the quality so...ya.

It looks so pixelated to me.. But on my other device that records 720p, it records way lot better than this..

There is way too much movement on both videos. I don't any camera phone could do better under those circumstances.
As a test, take another video without so much movement on the camera end and see if your quality improves.
Good luck.

That does not look like 720p to me, movement or not. Strange??? Take on in 1080p and upload it so we can see how it looks.

use the mod in my signature, re-shoot, upload and report back
by default 720p records at ~6mbps which for fast motion material can turn out blocky
download "media-profiles-final-holmes6.zip", flash in CWM, reboot

Recording Video 1080 screen jittering all over the place

When I record a video in 1080 the screen flickers and moves all over the place and is very jerky. But when playing the recording back its fine, apart from the jerky playback due to the low frames per second.
Anyone else had this problem

Can you make a video to show us what happens exactly?

A new way to bypass compression!!

Hey.
At the One X when I choose stabilizations an image while filming program is falling apart. When taking pictures, the image jumps and crazy about the program.
Movies shooting in good quality, but it hangs ...

Hmm? It has always supported the One X.. I've had it installed for a month already -_- Bypasses compression, but not dropped frames. Still as bad as stock cam.

only a few days ago then it started to officially support the one x.

Nice, just installed the Pro version, photo's uncompressed, you'll get a file size of 4,5mb, instead of the 1,5 of htc, better quality
you can record movies in 3gp and mp4.. I've set it to mp4, because that runs better on the One X
also the bitrate to 30mbps, instead of the 7 you get from stock htc camera
stereo quaility record on 320kbps and 48hz
218mb for 1min mp4 movie, hmm haha
maybe I should try 20mbps bitrate

Do you have drop frames in video?

Same happens to me when I try to activate the stabilisation in the camcorder.

Great camera app, I'm playing with it at the moment trying all options and buttons.
Recording in mpeg4 with video bitrate of 100Mbit and video framerate 30 plus resolution 1920x1088. (5 seconds video is 16,9mb)
Switching between picture and camcorder works fine for me and also stabilisation I've enabled, no freeze.
I still use the free version.
I can switch between picture and camcorder without problems.
Also stabilisation I have enabled.
Edit; the camcorder is very very nice, without it the camcorder is great as well but if the zoom would work fluent it would be a kick ass camcorder!
Edit 2; the zoom does work fluent! You can zoom in and out with the volume button WOW !!!!
Last edit; the zoom isn't fluent but I can live with that (hopefully it can be fixed in futher development), bought the pro version.

* Auto rotate video

On my stock HOX the free version of lgCamera hangs whenever I go to video-recording mode forcing me to click the menu button to exit the app. It also, somehow, manages to shut down the camera service making even the stock HTC camera to malfunction!
So far the latest Camera ICS (free version) has managed to work flawlessly with my device, making incredible videos that are almost 500mb in size for a 2min clip, but remains on the 24 frames all the time. Videos do look smooth though.
What I want to know is if someone using lgCamera has managed to bypass the stock framerate limit of 24fps? And what are the results?

I'm on a no rooted stock HOX as well, latest 1.29.401.11
Weird but all does function fine for me, no freeze nothing.
I've set the frame rate at 30 but how can I check if it's real 30?
Edit; your right, last video does 21 frames per second.
Edit; my apologies I just realise by reading your post a second time that you do not have any problems on latest version as well.

Hi again,
I've just had a very fast reply by email from the developer of lgCamera.
He told me that previous version 6.25 did hang sometimes but latest version 6.3 is checked on all mode and shouldn't.
Are you running the latest version?

exactly the same issue with paid app, latest version.
it's the only app so far that managed to **** up the stock camera, needed a reboot to get it working again
i also have wrong aspect ratio in the viewfinder after pressing record, when shooting video, but the recorded material is fine....
So far Camera ICS+ is superior, even with 24fps.

The developer of lgCamera has opened a new thread for beta testing
in the general apps and games all device Android section >> HERE

Yes I downloaded the latest free version from the market. I downloaded by other means the old pro 1.25 version and it works flawlessly, it manages 30fps while recording from a moving vehicle! Strange, right?
You can check the framerate and other properties of your videos by opening those files with MX Player.
So, does the newest version lgCamera in your case, create videos with a higher bitrate than the stock camera?

Camera Modes - what does HQ actually do ?

As they title said I tied to find out but am at a loss in trying to find out exactly what is happening when we use the HQ mode in the camera app.
In night scenes it seems to produce a better photo but the shutter speed is the same. One plus have not really said what they have changed since the HD to HQ update so wondered if anyone could let me know ? Is it an extra stop in exposure maybe ?

Just watch this video:
https://www.youtube.com/watch?v=md3Ow6AEwLU

Mine still says HQ

Thanks for the video but it didn't really answer my question as it was only a comparison.
That video just compared the 2 options of HD (which has slightly changed since they renamed it to HQ) and HDR. It does not explain what kind of post processing happens apart from staying it used a de noise filter. I wonder what "exactly" is happening with exposure, contrast, saturation etc when you use this HQ mode ?
If anyone knows that would be really helpful.

Crap. I read it wrong. I thought it said HQ recently got changed to HD. And does anyone elses HQ lag like crazy?

@jdawgg21 Nope, that's not it.
When using HQ in lowlight, it automatically reduces shutter-speed even more compared to the already lower speed in auto-mode.
Lower shutter-speed = lower framerate
1/30s = 30fps
1/10 (mostly when using HQ) = 10 fps
When others say they don't see the lag, it must only mean they did not test this in the same lighting conditions as you did.
It "lags" here too and so does it on every device which will use 1/10 or even lower shutter speed which shows you a real-time preview of what the image will approximately look like when taking the shot.

Finally a sensible answer. Thanks man. I had been asking around and Juan Bagnel said it's probably doing something like a dslr de noise function so what you said makes sense I have only used it indoors with artificial light so probably had no lag but so is what is displayed on the screen if it is leggy is representative of the shutter speed ?

I have heard from a Carl Pei interview that the camera is the reason for the phone having 6gb of ram because it snaps 4 photos at the same time we snap one photo. The phone then automatically chooses the best one photo of those four photos. I reckon that is also a probable answer due to the lag you are experiencing.

No, this is not the answer for the "lag". Why doesn't it lag in good lighting then?
I already gave the correct explanation for this.
As an example: I don't know if you have experience with the OnePlus One. It also started lagging much heavier in lowlightconditions due to the low shutter-speed.
Eventually, Sultan released his modded camera hal which forced the camera to not go below 1/30s on the shutter-speed.
The result was a perfectly fluid viewfinder regardless of the lighting conditions.
I am only talking about the fluidity of the viewfinder here. (Shutter-speed and video-framerate is a whole different story not to be mixed-up here...)
I've seen this interview too,
but I don't agree with him that it takes the best of these 4, instead I think that it somehow combines them into one.
This often results in more blurry pictures, even in good lighting!
Check this video I did on this issue:
http://www108.zippyshare.com/v/KidtanPE/file.html
As you can already see in the video, all images were taken without HQ or HDR. You can clearly see this when taking a picture and quickly swiping to the gallery.
For an instant, you will see the unprocessed picture which quickly changes as processing is being applied! Sometimes to the worse though :/
This gets more pronounced the more the ISO level goes up on a shot.
I was holding my phone as steady as possible and you can see that the shots which are displayed first look sharp before postprocessing.
So how can this be explained when, as Carl says, "the camera takes the best out of 4 shots"?!?

I first thought that in HQ mode, the camera is doing Dynamic Denoise
Grainy pictures are a thing of the past with Dynamic De-noise, which takes several photos and compares them to reduce noise and improve clarity.
Click to expand...
Click to collapse
Source
However GSMA review says that the Denoise function gets activated automatically when there is minimum handshake and is not dependent on modes.
A few other things I have noticed.
1) On 3.1.x the noise suppression was very aggressive, almost like a water paint effect. On 3.2.x, the photos are more natural. Still less noise that normal mode.
2) The minimum shutter speed in HQ mode is 1/10 while without HQ it is 1/17
3) RAW is disabled in HDR as well as HQ modes. This makes me think that the HQ (like HDR) is using multiple snaps to filter noise that is Dynamic denoise. If you quickly switch image preview after clicking a pic, you can see the transition from normal to HQ happening. This is definitely not normal noise reduction.

This is exactly what I said in my post right above yours and it even happens when HQ and HDR are disabled.
Check the linked video. I bet this is what you mean.
I hate this behavior, often faces are smoothed out because of this, even in perfect lighting conditions.

Hi, it seems the HQ mode does not generate RAW file, someone He checked?

A raw file is a photographic negative without any processing applied to it.
So even when the app would generate a raw file in HQ mode,
it would not look any different than the raw file created with HQ disabled.
My best bet is that the app is saving its resources for the HQ postprcessing,
thus completely skipping the raw part intentionally.

Snapdragon S10/+/e owners please read: Possible bug with lag and stuttering

Guys, before you reply with any feedback, please read the following post and links in full. It would also help if you posted details of your device like the following, which is mine:
Model: SM-G9750 (Hong Kong S10+)
Build number: G9750ZHU1ASF1
Completely stock, no settings changed
Only YouTube Vanced installed (for testing purposes)
Click to expand...
Click to collapse
Summary: An intermittent stutter or lag (most notably during fullscreen 4K HDR playback, in my case) which only goes away when you activate certain screen recorder applications like Game Tools or AZ Screen Recorder.
Below is a list of posts that highlight this problem that I and a few others are experiencing. The common denominator here is the use of a screen recorder, which removes any present stutter or lag.
https://forum.xda-developers.com/s10-plus/help/lag-stutter-overall-choppy-t3914381
https://www.reddit.com/r/galaxys10/comments/btwfbl/anyone_experiencing_stuttering_or_frame_drops_on/
https://www.reddit.com/r/galaxys10/comments/b79cw3/is_snapdragon_really_that_much_worse_than_exynos/
https://www.reddit.com/r/galaxys10/comments/b4nftn/snapdragon_s10_laggy_on_4k_youtube_playback/ (video evidence of problem)
The following two are from myself. My problem is that all 4K HDR content (could extend to other formats also but I need to do more testing) is stuttering or dropping frames. Screen recorder on and boom - it's smooth.
https://www.reddit.com/r/galaxys10/comments/ch172q/snapdragon_owners_does_this_type_of_video_play/
https://forum.xda-developers.com/s10-plus/help/sm-g9750-video-playback-throttled-t3950757
The lag returns as soon as you deactivate screen recording, which suggests that this is either a bug with the CPU or GPU not being optimized or boosting its frequencies properly, leading to these stutters.
I've put Snapdragon in the title as these posts all appear to be from Snapdragon owners, whether it's the US or HK variant. I don't recall ever having this issue as a last generation S9 Exynos owner. If you are an S10/+/e Exynos owner and encountering this issue, you could still try using your phone normally, with a screen recorder active and then without, to see if there is any performance gain (as crazy as it sounds, it might actually make a difference).
Below is a test I'm using to demonstrate my problem. It involves installing apps (namely YouTube Vanced and either one of two screen recorders I've tested it with), so it's not the most convenient. If I find a better method, I will update the post accordingly.
You will need YouTube Vanced. I'm suggesting Vanced because the original YouTube app doesn't let you view at 4K resolution.
Firstly, open Vanced and tap the account icon in the upper right. Go to settings, Vanced settings, Video settings and then toggle Resolution Checks to ON. Refresh and restart the app.
Now open Game Launcher, tap the three dots in the upper right > Add apps and add YouTube Vanced to the list. We're doing this for the screen recording function which I'll mention later.
Note: if you don't have Game Launcher or Game Tools, you can try AZ Screen Recorder as an alternative. Nice Shot does not work.
Once that's done, here's a 4K 60fps clip for you to try. It should be easier to perceive any hiccups with the higher frame rate. Please set the resolution to 2160p (tap the three dots in the upper right) and watch in fullscreen / landscape orientation:
https://www.youtube.com/watch?v=LXb3EKWsInQ
Panning shots work best. For reference, see points 0:19, 0:46, 1:48, 2:14, 2:42, 3:04, 4:11 and 4:41 in the video. Does it look like it's stuttering or dropping frames intermittently?.
Now, swipe up from the bottom of the screen to show the navigation bar (you need the navigation bar enabled to use the recording function) and tap on Game Tools, which is the leftmost button. Tap Record.
While the screen is recording, are the stutters now gone? To my eyes, the video plays back perfectly while the recorder is active.

[email protected] is where I experience constant stutter. You will need to override resolution checks in Vanced to watch at that resolution: Tap the account icon in the upper right. Go to settings, Vanced settings, Video settings and then toggle Resolution Checks to ON. Refresh and restart the app.
Don't forget to try it with the screen recorder on please, to compare if playback is smoother.
Just realized you're on Exynos, so the issue might not pertain to you, though there's a chance I might be wrong in that regard. Thanks for testing though - more feedback is always welcome :good:

Appreciate anyone else willing to try, of your own volition of course. Doing this purely to raise awareness on the issue and gather feedback.

I just tested this using the supplied download links for the actual video and AZ screen recorder.
In all honesty I couldn't see any difference between the video running with or without the screen recorder recording it. They both looked smooth. I was using the default video player to watch the downloaded video.

That looks like the Samsung video player, but no matter since the problem persists across other players too. MX Player in HW decoding seems to be the worst performing one for me.
Did you watch in landscape fullscreened? I keep forgetting to add that detail. If it was the same regardless, then I guess that removes the US Snapdragon from the equation. But thanks for taking the time to test, much appreciated :good: People probably think I'm bullshitting but once I find a concrete way to show what I'm experiencing, I will update this thread.
So far I've only had confirmation of this problem from two (yes, only two but it's still something!) other people, and they also happen to be owners of the HK S10+ variant like myself. If there are any other HK owners out there, I could really do with your feedback on this too!

Yes , I watched it in landscape mode, even compared the first few scenes where the camera pans etc with screen recorder on and off, couldn't tell the difference.

Mx player with hardware decoding is no problem, smooth as butter. Snapdragon U1.
What does YouTube report with nerd stats turned on for the dropped frames line?
No offense but your premise is flawed at best. All you have done is made a subjective claim backed up by no legitimate measurable evidence..
Having people install screen recorders and play videos is not 'testing' anything..
Best of luck

That's been tried by someone already but the thing with these cross-comparisons is that they aren't conclusive enough for some people. For me it's crystal clear because I already know what to look for.
Here, this link was in the OP: https://www.reddit.com/r/galaxys10/comments/b4nftn/snapdragon_s10_laggy_on_4k_youtube_playback/
One on the left is HK S10+, Exynos S9+ on the right. Make sure it's in [email protected] so it's as clear as possible.
The most obvious thing is that the scrolling is laggy on the HK model, but if you look closely, the video is stuttering too (look at the zooming out shot at the beginning). Exynos is completely smooth.
Stuttering video is a big no-no for me, really should not be happening on a phone of this spec.

Okay fair enough my test isn't the most thought out, but if you have any better suggestions on how to demonstrate the problem, you're more than welcome to provide them.
Stats for nerds doesn't show dropped frames, so it's likely that any FPS monitoring software would be useless too.
No it's not a subjective claim because if you read through the post and links in full, you would see a number of people confirming the problem. Doesn't matter how few, it's still an issue that shouldn't be ignored.
And one of the links has evidence in the form of video comparison: https://www.reddit.com/r/galaxys10/comments/b4nftn/snapdragon_s10_laggy_on_4k_youtube_playback/ please watch it @ 1080p60 on something larger than a phone screen.
The one thing I should've probably clarified is that I'm on the HK S10+, but those links indicate that US variants have a similar issue too. If yours doesn't have it, then cool, you're good to go :good:

That's been tried by someone already but the thing with these cross-comparisons is that they aren't conclusive enough for some people. For me it's crystal clear because I already know what to look for.
Here, this link was in the OP: https://www.reddit.com/r/galaxys10/comments/b4nftn/snapdragon_s10_laggy_on_4k_youtube_playback/
One on the left is HK S10+, Exynos S9+ on the right. Make sure it's in [email protected] so it's as clear as possible.
The most obvious thing is that the scrolling is laggy on the HK model, but if you look closely, the video is stuttering too (look at the zooming out shot at the beginning). Exynos is completely smooth.
Stuttering video is a big no-no for me, really should not be happening on a phone of this spec.

So now we're talking about the scrolling when the video is played minimized like the reddit video? Yes mines like the same laggy. But the video itself full screen is ok.

Not the scrolling specifically because that's related to the problem. For me the scrolling is laggy AND the video stutters. Are you sure the video is completely smooth? It might seem so but on mine there are frame drops present - even if it's very minor, there should be none at all.
It's best to compare with another capable device side-by-side with your own eyes, as no video recording will be able to demonstrate this clearly enough. There's also a chance that some people aren't sensitive enough to stutters and might not even be able to perceive them (I'm not saying you are, this could genuinely not be happening on your device).
And even if the video doesn't appear to be stuttering to you, shouldn't the laggy scrolling be enough cause for concern? A last gen phone is running smoother and that's not acceptable. Don't settle for mediocrity guys.
edit: before anyone questions the absence of screen recording in that video, the person who uploaded it has another post on reddit where he mentions it fixing the problem.

Watching it at 1440p on native YouTube app it seems the scrolling is smooth. But on Vanced @2140 not so smooth scrolling. Probably the Vanced app or cpu etc binning on the snapdragon.

I don't think it's the app or hardware because once I turn on the screen recorder, playback is perfect (landscape). I'm no expert on this but a logical guess means there's a frequency boost while the recorder is active, removing the stutters.
If I could find a less ****ty workaround that does the same, I would be okay with it, but there isn't

No lag here. My phone has been flawless. SD
