Video Camera judder issues

[astraelraen]

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 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 not dropping frames. It's gotta be an encoding issue or a playback issue.

The weird thing is, if I transfer the videos to my computer they seem to play back fine.

I have the exact same video open in a browser and Media Play Classic side by side at the same time. The one I uploaded to Google+ directly from my phone is playing with a lot of judder vs the one playing in Media Player Classic is playing fine.

Has anyone else experienced this?

It's a frame rate issue. I just viewed all 5 of the videos I took today and the frame rate fluctuations are huge. The "best" video fluctuated between 21 and 30fps.

The worst video had a minimum framerate of 10 fps and a maximum frate rate of 30fps. That is a huge difference and makes the videos practically unwatchable.

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

Did you notice a correlation with frame rate and the amount of available light?

All five of those listed were taken outdoors in the middle of a sunny day 720p resolution with no other weird settings.
