Replying to scottgny3:

"Maximum attachment size: 2621440 bytes"

the original mxf file is 376 megabytes.. can i ftp it?

Please read http://ffmpeg.org/bugreports.html (there is no hard file size limit).

Is the problem only reproducible with an external library (libx264, faac) or also with -vcodec mpeg4 -strict -2 -acodec aac?
Are all options necessary to reproduce the problem or is "ffmpeg -i input -vcodec mpeg4 -strict -2 -acodec aac -qscale 2 out.mp4" sufficient?

Please provide the complete, uncut console output to make this a valid ticket.

[scottgny3]

uploaded both the original mxf and transcoded m4 files with text (includes full output and all "preset" params).

Please reopen if I miss something (and if you can add the command line together with complete, uncut console output).
