question about m4v

[esr2]

Good morning Jan. I have a 5 minute movie (mv4) with a piano track. I want to increase the speed without changing the pitch of the music. Perhaps your deinterlacer would work? What do you think?

Thank you,

If it has a video track too I would expect that to work.
You would need to do a standards conversion.
