Topic: RIFE Audio out of Sync

Hello Guys,

I just switched to SVP, because I wanted to try the RIFE AI Interpolation.
Sadly, as soon as I try to use RIFE, the Audio is desynced badly.
When I start to watch a movie the picture freezes for 1-2 seconds, while the audio still goes.

What can I do about that?

I am watching mostly 4K Movies in MPC-HC.

I have an RTX4090, so performance shouldn't be an Issue.

Performance will be an issue. RIFE is extremely demanding, so it depends on your refresh rate and what you are trying to push at default.

Are you dropping frames or having any delayed frames when looking at the stats in MPC?

Try using RIFE at 2x instead of "to screen refresh rate", to test if running at 48 FPS it works without issues.

I also recommend you download  rife_v4.25.7z from Sep 19th from the link below. Not the LITE version from a few days ago.

https://github.com/AmusementClub/vs-mlr … nal-models

Copy the rife_v2 folder from that file above and place it below next to the rife folder:

C:\Program Files (x86)\SVP 4\rife\models

Now restart SVP (exit and open it) and you should see 4.25 v2 as an option to select, right now it's the best version available for quality.

Remember, the first time you run any NEW resolution, RIFE will have to build CACHE for that resolution for that RIFE version.

That takes time, just let it build in the background.

When you are free and happy with a RIFE version, run a bunch of movies and tv shows one by one to build the cache for each different resolution.
