Problem with converting from avi to avi

[alexxz]

I was converting series when get a problem. 1 avi from 20 files do not want to be converted. I get empty file on output.

I do not really know what is wrong or what should I do

Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height

Also I think line "Seems stream 0 codec frame rate differs from container frame rate: 23.98 (65535/2733) -> 23.98 (8000000/333649)" is very fun.

Did you try ffmpeg -i example.avi -s 400x240 -vcodec mpeg4 -b 500k -r 65535/2733 out.avi ?

Thank you, it helps me! Sorry for bothering you!
