Topic: HTPC with SVP and madvr

I recently purchased SVP to test out the capabilities of RIFE. I want good frame interpolation to watch regular movies in my home cinema. The motion enhancement on the projector produces way too many artefacts to my liking.
Because I now use an AMD 6700xt GPU, I can only transcode small pieces of movies to see the effect. And I like what I see smile

Long-term I would like to build a dedicated HTPC which is capable of running SVP and madvr simultaneously.

Some questions:

1. Has anyone already built a HTPC using an RTX4090 and is it capable of running SVP and Madvr smoothly in 4k HDR (to 60fps)? Perhaps better wait for the new 50xx series?
2. When I transcode HDR files, the metadata is gone. I understand that SVP isn't capable of doing this properly. Is there a way to re-add this metadata manually?


I look forward to hearing from people who use SVP for regular films, not just anime.

No one? :-(

If madvr is too slow, maybe try MPC VR or mpv instead?

Here there are some parameters that add some metadata, not sure if it has your desired effect:

If you have a non-HDR video, you can enable Nvidia App's HDR filter on it by using https://www.nexusmods.com/site/mods/781
This should display any non-HDR video in full HDR.

Re: HTPC with SVP and madvr

madvr is long dead. Use mpv with 4k x2 custom resolution on tv 48 Hz or 50 Hz with +few % speed up

4090 should be enough for that rife

Best advice here.

Forget MPC and Madvr, switch to MPV.

RTX 4090 should be more than powerful enough to push 4K at 48Hz.

You can create a custom resolution (keep it 4K) with a custom refresh rate (48Hz) using a program called CRU. Hopefully that works with your projector.

Then you use RIFE version 4.18 (best one for movies) with MPV and at 2x should convert all 24fps films to 48fps, and I can give you my MPV configuration to help as well.

If you need help, let me know. If I don't see your replies here, private message me so I come back to check here.

Re: HTPC with SVP and madvr

Thanks for all the advice.
Re-adding the metadata works, but the colors are still washed out. I just wanted to transcode some files to see if the investment in a 4090 is worth it, but even without the HDR metadata, I can judge the motion. I know that HDR is no problem in real-time frame-interpolation.

Projector doesn't accept 48hz and in the files I transcoded, I liked x2,5 (60hz) better to be honest. Would a 4090 be able to do this real-time or better wait for the 5090?
Is HDR tone mapping in MPV as good as madvr? I always thought madvr to be superior.

Will check out MPV, finding and adjusting the settings seems to require some studying :-p


Seems I can only post once every 2 hours???

Re: HTPC with SVP and madvr

I'm on an RTX 3090 so cant speak on the performance of the 4090 and if it's capable of doing full 4K at 60FPS with RIFE 4.18 for example, but personally I am waiting for the 5090 release.

You can also ask in the RIFE thread regarding RIFE performance questions, as most people only check that and not other threads.

Re: HTPC with SVP and madvr

I think it’s wise to wait the 5090. Never hurts to have a bit too much performance :-p

I see that smooth Motion of madvr doesn’t work with svp vapoursynth. That’s a pitty, you’ll need that to transform 48fps to 50 or 60fps without stutter. Meaning 48fps will nog work (well) with madvr.

Re: HTPC with SVP and madvr

Anyone who can point me in the right direction to transcode files with HDR?
There are HDR movies to be found on the internet who are transcoded with the latest RIFE version. It should be possible then, no? Another program?

What???>>
madvr is still getting updates and its tone mapping is far superior to the other options
