Custom Resolution Utility (CRU)

[Framerate]

For those of you using non-standard framerates like 47.952fps, 48fps, or anything else, I was wondering how you get audio to external speakers?

I’m using an AVR with external speakers and Google AI is adamant that AVRs, as well as HDMI splitters etc., will at minimum introduce microstutter or microjudder to custom framerates, if not convert them to 50fps or 60fps or create a black screen.

Meanwhile, end users are saying that it will work; however, they are probably going by eye test and I doubt they have ever tested it for microstutter or microjudder. Google AI also recommended “extend this display” at one point, but then at another said that it would also create these issues and possibly a lot of audio sync variance as well.

I want to interpolate mkv movies to 47.954fps and 48fps and output them at either 1x or 2x Hz without getting video artifacts or bad audio sync variance, and am wondering the best way to do it. I have an audio sync measurement device so I can correct for bad sync latency, but not for bad drift or variance. I need a steady number, even if that number is big.
