[HELP] Conform 25fps to 23.976fps

[shijan]

out of curiosity: Why?

A lot of 24fps film content on DVDs is simply conformed to 25fps and audio is stretched. So i guess the main idea here to conform it back to 24 original fps and stretch audio?

But i guess in most cases it may not worth and this is why:
- 24 vs 25 fps difference is near invisible.
- It is usually a high amount of risk that not only 24-to-25fps conform but additional unusual artifacts may present in DVD.
-It is unknown if audio pitch was removed during stretching or not, so stretching it back may add additional audio problems.
- If audio on DVD is already compressed - editing and stretching it is a bad idea.
- DVD format is evil, so if possible always search for modern HD/bluray release version that use native 24fps, progressive formal, better compression, more details and better dynamic range because rescanned from film master on modern 2K or 4K film scanners.
