Video slicing

[yug...@gmail.com]

Hi 

I have a bunch of p2 files which i need to encode it to avid format 

The below command works well , but it takes a lot of time to slice the file if the -ss [00:19:38.840] is toward the end of the Video duration .I guess it runs from entire Video duration to find the exact start position. 

ffmbc.exe -i "V.MXF"  -i "A00.MXF"   -i "A01.MXF"  -ss 00:19:38.840  -t 00:00:10.920 -vcodec dvvideo -pix_fmt yuv411p -b 25000k -minrate 25000k -maxrate 25000k -acodec pcm_s16le -ar 48000 -ac 2 -map_audio_channel 1:0:0:0:1:0 -map_audio_channel 2:0:0:0:1:1 -timecode 00:20:02:06 -y "Output.MXF" . if i give -ss before the first video file then there is an audio sync out problem .

however if there was a case of single Video and Audio file i would have done it by giving -ss before the Video file e.g

ffmbc.exe -ss 00:19:38.840 -t 00:00:10.920  -i "VA.MXF"   -vcodec dvvideo -pix_fmt yuv41p -b 25000k -minrate 25000k -maxrate 25000k -acodec pcm_s16le  -y "Output.MXF"

Hi,

I have posted a patch a few weeks ago that might help in this case.

Haven't tested it on MXF files or command lines with multiple inputs, though.

HTH,

Robert
