That's a workaround which has other problems...

The jerking must be a bug in ffmpeg. I just made this test:
1. Use a 5472x3548 PNG picture as input. Jerking is barely visible, only 
about 1 pixel.
2. Convert the PNG picture to JPG and use this as input. Jerking is now 
clearly visible and annoying.
