question about m4v

Swiss army knife for anything related to interlace.

question about m4v

Postby esr1 » 18 Nov 2016, 17:04

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.

Thank you for responding, Jan. What is a standards conversion?

The most common case used to be PAL <-> NTSC conversion. That involves changing the size and frame rate.
These days you can think of converting 720p50 to 1080i60, which means changing frame rate, size and interlace type.

Deinterlacer has six project types: deinterlace, reinterlace, inverse telecine, change field dominance, standards conversion, bare project.
Changing movie speed is part of the standards conversion interface.

Thank you Jan, for the details. But back to my original question: with your software, can I keep the (audio) music pitch from rising while I speed up the video? Thank you,

Yes, it does that by default (using QuickTime for that).
