[FFmpeg-user] Unable to reencode corrupt video file

[Schampignon Cristobal]

Hi, thanks for your answer.
 
Yes I included those values now. I increased the probesize and the analyzeduration-values step by step. This is the result:
 
D:\ffmpeg>ffmpeg -i Video1.mxf -q 1 -ss 0 -t 1200 -frames 25 -codec:v mpeg2video -probesize (1000000000000000000000) -analyzeduration (500000000000000000000) output.mxf
