Something in this video segment causes jerking motion #127
Comments
Hi, Here is all configurations value when I tested.
Output with interpol= no Ouput with interpol = bilinear |
Thank you for trying it out for me, @Ssong24 . I have already tried interpolation off and on with same result. I think this could be my

Interpolation is not causing this. GPU is also not used, unfortunately. |
Here are the exact cmd lines I used, @georgmartius. First pass Second pass Solution: use ffmpeg interpolationOn second pass I set the frame rate from 30 fps, the source frame rate, to 48 fps in order to have more frames for interpolation by ffmpeg video filter instead of vid.stab interpolation. Problem: vid.stab does not support custom frame ratesOn second pass, unaware of the new frame rate, vid.stab has used the video stabilization analysis of the source video in its original frame rate and ran out of transformation data. A warning error was shown at the end of second pass encoding:
The jerking motion was gone but stabilization data was out of sync with the output video and introduced more shakes than the original. |
This 12-second segment was extracted from raw footage. The 12-second segment before it worked fine with vid.stab so there must be something in the video encoding causing the jerky output. Stabilizing the whole source footage will result in jerky motion from start to end but extracting the first 12 seconds only and stabilizing that results in good stabilization. Extracting the second 12 seconds of raw footage (posted here as the source file) and stabilizing that results in jerky motion.
Extracted segment highlighted in the timeline with blue line.
