ffmbc -i "T:\CONTENTS\Video\0002U3.MXF"
-i "T:\CONTENTS\AUDIO\0002U300.MXF" -i "T:\CONTENTS\AUDIO\0002U301.MXF"
-ss 00:15:58:24 -t 00:01:55:10 -vcodec dvvideo -pix_fmt yuv420p -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
00:35:48:18 -y "NewOut.MXF"

I am converting P2 files to DV op-1a also slicing the file from -ss
(00:15:58:28) for duration of (00:01:55:10) . it does its job very well but
the issue is it takes time to start slicing.

whereas if i send the following command it starts the job immediately but
then audio is not in sync with Video

ffmbc -i "T:\CONTENTS\Video\0002U3.MXF" -ss 00:15:58:24
-i "T:\CONTENTS\AUDIO\0002U300.MXF" -i "T:\CONTENTS\AUDIO\0002U301.MXF"
-t 00:01:55:10 -vcodec dvvideo -pix_fmt yuv420p -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 00:35:48:18
-y "NewOut.MXF"

thanks

This is the current behavior, fast seeking can be done putting -ss before -i
