Can I second this request - I have over 50 saturday morning cartoon intros and it would be shame not to have a complete nostalgia box for people to play with!

I hit it on some videos that seemed to have the same settings - my fix was to run then through handbrake as webm - then the converter was fine picking them up and not crashing.

Ive not tried just going straight through ffmpeg yet - 

Code Select Expand

ffmpeg -i "input.mp4" -r 24 -vf "scale=210:135,hqdn3d" -b:v 1500k -maxrate 1500k -bufsize 64k -c:v mjpeg -acodec pcm_u8 -ar 10000 -ac 1 output.avi"

Alternate scale options:

scale=210:135:force_original_aspect_ratio=increase,crop=210:135:exact=1,hqdn3d
scale=210:135:force_original_aspect_ratio=decrease,format=yuv444p,pad=210:135:(ow-iw)/2:(oh-ih)/2,format=yuv420p,hqdn3d
