Video Camera Judder - Samsung Galaxy Nexus

I posted this over on Android Central as well, but decided to post it here to reach another audience.
I've taken a few videos with my Nexus at 720p and there always seems to be alot of stutter/judder in the video. I haven't really tested 480 or 1080p
I first thought I just wasn't holding the phone steady enough... and that may be some of it. But I have taken 10+ videos and on play back there is always some judder. It's like the video camera app is taking the videos in the wrong FPS or its dropping frames or something. The sound is usually crystal clear and doesn't miss a beat, so I'm guessing it's a frame rate issue.
I viewed all 5 of the videos I took today and the frame rate fluctuations are huge. It makes them practically unwatchable... at least to my eyes.
Frame rate : 17.042 fps
Minimum frame rate : 10.002 fps
Maximum frame rate : 30.040 fps
Frame rate : 18.020 fps
Minimum frame rate : 10.002 fps
Maximum frame rate : 30.040 fps
Frame rate : 30.000 fps
Minimum frame rate : 20.766 fps
Maximum frame rate : 30.040 fps
Frame rate : 30.000 fps
Minimum frame rate : 15.010 fps
Maximum frame rate : 30.040 fps
Frame rate : 30.000 fps
Minimum frame rate : 15.010 fps
Maximum frame rate : 30.040 fps

I'd like to know also

Could this be caused by low light conditions? Sometimes when the light is poor, the camera app will skip some frames to allow enough light to reach the sensor (longer exposure time).
Try again outdoors on a sunny day to see if it's that. It might be possible
to avoid that effect (but have darker videos) by changing the scene mode in the camera preferences.

Just tested my camcorder, I get some random studder also on 1080p. Interesting, it was in low light though...
On 720p no judder whatsoever.
Maybe it loses focus for a second so it tries to get it back? I have no idea

The 5 I posted in the first post were taken outside in sunny conditions at midday. I will try tto take a few more today to test it again.

[REQ/Vote] Video bitrate enhancements

Right now the 1080p video bitrate is bordering max 10mbps, which is quite low and shows artifacts / blur in fast moving scenes. The 720p video is even worse @ around 5-6mbps.
A workaround now is to use the ICS Camera+ application and tick 2x bitrate. However watch the auto whitebalance settings since they give a purple hue. Set it manually.
This is a hopeful request to the OneX devs & modders to do their magic and squeeze more mbps as well as maybe lock a minimum FPS value so it doesn't drop to hell in low light and the expense of exposure.
i'd be happy with 720p @ 15mbps and [email protected], both at solid 30FPS
thanks in advance and vote for the feature!

media_profiles.xml and Camera.apk are the place to look for improvements.

community would be grateful if you can help work this out!
Camera ICS + features like background and face effects don't work for me shame too, they look like fun!
they should also tweak the camera in order for it not to compress the pictures so much! HTC's stock camera app produces pictures that are twice smaller than pictures taken with other camera apps (or with a common 8mp camera) with no effects nor anything

i tried playing around with the XML to no avail...they key is in the APK.
bumping this hopefully someone can take some time to figure it out....

Hox has a image processor so I'm guessing that will need to be flashed, or bypassed.

Not only video, but still quality too.
In order of priority:
* Fix the frame rate issues first (dropped frames are VERY distracting; currently video stutters badly)
* Provide adjustable image compression levels including a very high quality mode. (Raw would be even better, but I doubt they'd consider that.)
* Provide adjustable video compression levels including a very high quality mode.

don't think that's the case because we have seen 2 alternatives that increase bitrate just with a modified APK:
- ICS Camera - still some quality (purple hues) issues in resulting videos + cannot select 1080p
- NoDo-GT's beta which is currently frozen with no download available
seems the limitation is in the recording profile used: [email protected] / 10mbps
the SGS3 (and the SGS2 for that matter) uses [email protected] / 17mbps.

http://forum.xda-developers.com/showpost.php?p=25693754&postcount=108
[8] Video: SGS3 is clear winner here. HOX does not record in High profile. It records at mere 10 Mbps Baseline whereas SGS3 does High Profile recording at 17 Mbps.
Maybe now with the kernel source released someone can work out some magic.....fingers crossed.
While compression is too high and bitrate is too low, there also one very important issue - fps. I tested again and again and again, the stock camera can only take video up to 23-24 fps, while using camera ics I can do 29-30 fps. This proves that the low fps of the stock camera is not limited by hardware. An update to the camera is needed...

Far more important than the maximum FPS is that it's steady. If there are no frames dropped, your eyes very quickly get used to a lower frame rate. If it keeps spiking up and down between high frame rate and loads of dropped frames, though, that's impossible to get used to.
Check my vedio
The quality is very bad!!!
Recorded by htc one x firmware 1.28
Not only the fram rate and image quality also the sound is very aweful.
You can notice the camera are always re focus and blur.
Watch this you will get my point

I didn't say you couldn't see the difference between at all, just that it wasn't as damaging to frame rate perception as all the dropped frames, which are a far more important issue.

The mixture of low light and alternating colours would tax any camera let alone a phone camera. Used in decent lighting the quality is decent enough and doesn't lose focus like that

Ok, let me rephrase... I would expect such hardware to be able to do 30fps constantly

Agree completely.
I hope nodo-gt starts working on modded camera for the one x again. I think the camera for the sensation is up to 40mbps now.

Low-Light in slow motion recording?

Hey guys,
So a friend was showing off slow-motion recording on his Note II and I remembered "Hey my phone has that too"
I didn't actually record that time, but we had gone to the beach at night much later. I tried recording a video in slow motion. The lighting seemed enough when I viewed it from the phone, but as soon as I start recording the video in slow motion, the whole thing is dark. Now my question is why does it get dark in slow motion recording? I know the resolution drops but I have no idea why it gets darker. I could have snapped photos with the light present at that time, and the photos would be much better than how the recording came out.
Its more like when snapping pictures or taking normal videos in low-light, all is good. But for some reason in slow-motion mode the camera doesn't get enough light so the video appears dark. And Switching to Night-Mode Scene helped very little.
It needs to lower exposure to maintain the frame rate

This is the same with any high fps camera ever. To compensate for the higher fps you need to lower the resolution or exposure.

Zenfone 2 Camera is limited to 30 fps

Hi XDA
Zenfone 2 Rear Camera's sensor is Toshiba T4K37
Toshiba T4K37 Camera sensor specs are ;
1080p record at 60 fps
720p record at 60 fps
VGA record at 120 fps
We can't record at 60 fps. The frame rate doesn't depend on video resolution. Frame rate is always at 30 fps.
Anybody can remove this limit?
yes why not?
especially 1/8 slow motion feature must be add..
Did someone tried with another camera app ?
60 fps in 1/4 slow motion should be good
They definitely should implement 60 fps version!

Gaming performance on 1080p mode

Hi guys,
I was wondering if you noticed an improved gaming performance if the display is scaled down to 1080p? Thanks!
I haven't had any issues in default resolution so I haven't tried it yet..
Theres a YouTube video showing the difference between 2k vs 1080 and it's very minimal.
I see.. if it's very minimal then it's almost useless for me. I thought it would give the frame rate a slight boost.

The HTC 10 has the same mode.
On the thread in the 10 subforum it is quite a difference. Not only are the frame rates consistent but there is more detail drawn.
One of the biggest differences is battery consumed.
I did not click on the link in this thread but one game doesn't sound like consistent testing to me. Some games are capped at 1080p regardless of your setting.

Thanks mate. What I'm after is the stability of the frame rate. I play mobius final fantasy and even at normal setting under game tuner. I experience frame drop on high graphics setting. Hopefully setting the resolution at 1080p can do something

Pixel 2 XL Video Settings

I have read on multiple reviews and sources that I can record at 1080p at 120 fps and at 720p at 240 fps. However, when I go into the setting for video recording and select either 1080p or 720p I only have the options to select 30 or 60 fps.
Only my slow motion option has the option for 120 or 240 fps.
Is anyone else having this issue or are these reviews and sources all somehow mistaken? The fps at which video recording can utilize is much more critical than the resolution it records at. For instance, I would much rather record at 1080p at 120 fps than at 4k at 30 fps.
It's not an issue. Either what you read was wrong or you misunderstood what was written.
1080p 30/60 normal video recording and 1080 120fps and 720p 240fps slow motion is what the Pixel 2s can do.

Maybe the many many post and reviews I have read we're just not very clear on what they meant. But that's pretty much what I was expecting. Was having a hard time wondering how I could miss such an important setting. Hopey come out with some software that can utilize these fps settings that this phone is obviously capable of doing (since it currently does 120 fps at 1080p but only in slow motion).

You do realize that you can record in slow mo and not actually edit the slow mo in, right? Just make the slow mo bracket super small, throw it at the very front of video or rear. Trim it out. Volla! 120fps 1080.
Another option is to use Filmic Pro. You can manually set resolution and fps.

I tried this but the quality of video, seems to have something to do with the light exposure, suffers when in slow motion mode.
I don't want to pay 15$ for a camera app. I just want Google to release some software to really take advantage of the current hardware.
The camera is already so good and still has potential to be even better.
I love the phone though it's by far the most consistanly responsive Android I have ever had.

That's natural for higher frame rates. The more frames, the more light that is needed.
There is no way around that except for manually adjusting exposure and ISO. Which can be done in Filmic.
What you seek is available to you.
What I seek is an update to the Google software, not a third party application that costs more money, because it's not sure a big deal that I want to spend more. I am patient and can wait. Also it's not that big of deal to me, I was simply inquiring if anyone knew a way to set the normal video mode to a higher frame rate than 60 fps.
