[FFmpeg-user] Trouble converting MOD file to anything else

[Guy Helmer]

I have tried a number of approaches to transcode a new set of MOD files to MPG, AVI, or MP4 to clean them up for use in iMovie but nothing has worked for me with ffmpeg 1.2.1 (it used to work with an older version of ffmpeg from roughly a year ago). I always receive these errors from libmodplug and the output file is extremely short. Any help would be appreciated.

This is my latest try at a command line; adding a suggested -max_size option makes no difference:

> ffmpeg -i MOV005.MOD -strict -2 -s 720x405 -vcodec mpeg4 -b:v 2300k -filter:v yadif -aspect 16:9 -acodec aac -ab 192k -ar 44100 MOV005.MP4
