The projector is calibrated, but HDR wise, tonemapping through madvr is way better than when the projector is handling this...
My current computer is a 6700xt GPU and Ryzen 5 5600 CPU. Transcoding of 1080p files with rife 4.22 lite is at a pace of about 34fps.
I know there are many variables, but a general benchmark would be quite useful.
I would love to be able to use madvr and SVP for 4k hdr files, but I guess only a 5090 GPU would be able to do this.
I use a projector (Sony xw5000), so external HDR tone mapping (and frame interpolation) make a huge difference...
Topaz I only use for enhancements, never interpolation.
I am currently considering building a new computer. Since I often use SVP to interpolate movies with RIFE, I would like to have a system that can do that a bit faster than my current computer.
I also regularly use Topaz video AI to improve image quality before interpolating. There is a community for this where benchmarks are shared which allows you to estimate in advance the performance of a particular system. The new amd 9070xt does amazingly well, around the same level as the nvidia 5080.
I know RIFE is mainly optimized for Nvidia. However, I lack more precise data to determine which GPU would be the right one for me. I wouldn't mind saving up for the 5080 if it can transcode much faster than the 9070xt, or if it can interpolate 4k videos live, for example. However, I am currently a bit in the dark in this area as to what the concrete differences are.
Is there anyone who has either GPU who can share some numbers? For example number of FPS when transcoding a 1080p file? Or anyone who has a 5080 and can confirm that 4k HDR files can be interpolated live?
To my knowledge, it's still impossible to transcode HDR movies...
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?
Curious: is this a general problem with smooth motion (madvr) and vapoursynth filter or just from a specific madvr beta release?
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.
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???
Try to disable hardware acceleration.
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 
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.
