I have a play I recorded in MP4 format that I am breaking it down into individual scenes in MP4 format.

In most, but not all, the audio gets out of sync part way through.

I don't know if splitting the audio and the video in KDEnlive would help? Or are there some settings that would work better?

I was hoping to take these MP4 formatted scenes and then pull them together in another KDEnlive project so I can render them together (with added titles, etc.) and burn them onto a DVD to pass out to the other performers.

OS: Pop!_OS 18.04
Memory: 5.8 GiB
Processor: Intel Core 2 Duo P8700 @ 2.53GHz x 2
Graphics: Mobile Intel GM45 Express Chipset
Gnome: 3.28.2 (64bit)
Kdenlive: 17.12.3

Any help would be appreciated. Thank you.
