Thanks for quick reply. Below is all the necessary information.

I've sent an example MXF flowers.mxf videoclip into my email account
ftp6...@gmail.com (password: ftp6565ftp). Feel free to login and download
it. There is only one email, with subject "flowers.mxf videoclip (25 MB)".

thanks for quick reply.

I will try to split all above steps in a multiple posts.

First I cut a file with the following command:
ffmpeg -i flowers.mxf -ss 0 -t 4 -c copy -y 1.mxf

At this step I can observe the audio/video desynchronisation.

[FFmpeg-user] processing of mxf videoclips with ffmpeg

2014-07-10 Thread Pawel Por 
Hi

I'm trying to do the following 3 simple operations on my MXF movie.
I would like to:
- cut it
- make a sound in a videoclip louder or more quiet.
- merge a sliced videoclips into a single one

In all above steps it is very important not to loose both video and audio
quality.
I don't need to stick to any specific output format (the conversion is
allowed).

I've uploaded an example MXF videoclip into the following location (it
takes about 25 MB):
http://www.sendspace.pl/en/file/5e767ba82331b8203a87371

I found on the internet quite easily complete ffmpeg commands of how to do
those steps but unfortunately they didn't work well. Some of them generated
errors, some of them produced videoclip without an audio and others
produced videoclips with desynchronized audio and video

great thanks for help
