what do you mean? just run MPC-HC with 'Vapoursynth Filter' instead of 'Avisynth Filter'

I tried today ..

MPC-HC shows:
23:23:24.207 [E]: Playback [c85b13c2]: AVS - RIFE: failed to load model\n(C:\Users\patri\AppData\Roaming\SVP4\scripts\c85b13c2.avs, line 62)\n(C:\Users\patri\AppData\Roaming\SVP4\scripts\c85b13c2.avs, line 77)

I thought i could do this:
SVP menu -> Utilities -> Set environment variables for Vapoursynth

but this is not selectable, my SVP looks like this:

Can you smoothly interpolate in real time with RIFE x2, without losing frames? How are the colours?

Better results???

well at least for me
1080p@24 x4
MPC+MPC render: ~75% GPU load.
SVP's MPV default: ~85%

maybe different between users' setups.

This is puzzling. Apparently it is the mpv that is more efficient....

Thank you!

Pezede, I think you have the perfect setup to test what really matters in the success of your interpolation.

I think with 4K HDR x3 in real time with RIFE, there is no point in playing around with encoding tests anymore.

What everyone is probably interested in is what the minimum configuration allows for:
1. 4K HDR x3 in real time with RIFE
2. 4K HDR x2 in real time with RIFE

My test proposal:

LG 4K HDR Demo - New York.ts
Direct link: https://drive.google.com/file/d/1dfR5TT … _bGfEXUvJ/
Source: http://hdr4k.blogspot.com/

1. Reduce only the TDP of GPU in steps of 10%

100%  4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
90% 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
80% 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
70% 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
60% 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
50% 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time

50% interests me personally, as I will be able to passively cool the graphics card to around 250W TDP

2. Reduce only the TDP of CPU in steps of 10%

100%  4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
90% 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
80% 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
70% 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
60% 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
50% 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time

3. Reduce only the MHz of RAM in steps of 400 MHz

6000 MHz 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
5600 MHz 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
5200 MHz 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
4800 MHz 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
4400 MHz 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
4000 MHz 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time
3600 MHz 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time

4800 MHz is of particular interest to me because this is currently the maximum with true ECC

I know this is probably too many tests, so maybe a simple 4 tests to start with and that will explain a lot from all of the above:

1.  GPU 50% TDP 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time

2.  CPU 50% TDP (or 105W TDP or 65W TDP) 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time

3. RAM 4800 MHz 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time

4. RAM 3600 MHz 4K HDR x3 in real time pass or fail and if fail 4K HDR x2 in real time

Of course, it doesn't have to be today or tomorrow. It doesn't have to be anything at all. But I think you could help a lot of people to choose the optimal configuration for RIFE interpolation smile


Hey, I'm afraid that I don't really have the time to do those tests, it doesn't help that tinkering with ram on AM5 is far from a pleasant experience (I've tried)... sad

No problem. Thanks for the tests and I hope you will try to help other 4090 graphics card owners to replicate your real-time interpolation result smile

In fact, yes... That's why it's worth testing different configurations. I'm curious to see if anyone else gets a similar effect. However, checking why this happens is unlikely to be easy.

I have 32gb of ram. SVP and MPV combined only used around 4.2gb of ram

2. 4K HDR x2 in real time with RIFE

My test proposal:

Your proposal to find the matching GPU does not work as the tensor cores are very different between the RTX cards ...

For me personally, there is no choice other than the RTX 4090. If only for one reason - in passive GPU cooling, die size is the most important factor:

GeForce RTX 4090 has 608.5 mm2
GeForce RTX 4080 has 378.6 mm2

The difference is significant. Here it is not possible, as in active cooling, to control the cooling by adjusting the fan speed.

I will be able to passively cool the GeForce RTX 4090 at around 250W TDP. I need the maximum contact area for heat transport away from the GPU. That is why I am particularly interested in this TDP value.

I suggested to Pezede this kind of testing as I assumed he would not have the option to change GPU, CPU and RAM for testing. This is the simplest test to see how the drop in performance of the various components in the setup affects performance. What can be saved on and what is not worth saving on.

@Chainik

BTW it can generate a "multi-resolution" cache, for example one cache for "1920*1080 and below" but then the speed drops by ~30% hmm

look like they just fixed the bug https://github.com/AmusementClub/vs-mlrt/issues/20

Can you smoothly interpolate in real time with RIFE x2, without losing frames? How are the colours?

I'll do some further tests today and report back.

For reference my system is a 10900k @ 5.2ghz all core 32gb of CL14 4000mhz ram (not sure if very low latency or bandwidth plays the bigger factor here). Also works at x3 resolution in HDR.

The 4090 is mind blowing like x2 generational leap over my 3090. It so frugal on energy too!

EDIT----

Ok i've tested this further. Through MPlayer HDR works with Standard SVP interpolation (but not Rife). However since brining in all the new RIFE updates it seems to have broken HDR in MPV player. Even when using standard interpolation with Rife off MVP/SVP player is not playing HDR (even when turned off). I've even tested MPV on its own without SVP and it is not displaying HDR colours. I've posted my config file below for info:

Any ideas?

------------------
#
# THIS FILE WILL BE OVERWRITTEN WITH THE PACKAGE UPDATE
# Use %APPDATA%/mpv/mpv.conf
# OR SVP's menu -> Information -> Add. information -> mpv config. file
#     to define your own customized configuration
#
# Sample mpv configuration
#

# this is required for SVP to "catch" the mpv
input-ipc-server=mpvpipe

# hardware video decoder
hwdec=auto-copy
hwdec-codecs=all

# high quality video output, require rather fast video card
#profile=gpu-hq

# D3D11 renderer (default) is required for the HDR playback
#gpu-api=d3d11

# use VULKAN API if you have problems with the default d3d11 renderer
#gpu-api=vulkan

# miscellaneous options

# comment this one if you want mpv to remember the playback position
save-position-on-quit=yes

# fixes audio desync
hr-seek-framedrop=yes

#log-file=mpv.log
# this is required for SVP to "catch" the mpv
input-ipc-server=mpvpipe
hwdec=nvdec-copy
#hwdec=auto-copy

vo=gpu-next

-----------------

FINAL EDIT --- Adding this here incase anyone has the same issue. I needed to add the following to the config file:

--vo=gpu-next --target-colorspace-hint=yes --gpu-api=d3d11

The image clip you provided now plays at 50fps in HDR and looks fantastic.

One very happy camper here. Thanks everyone for your effors.

Re: New RIFE filter - 3x faster AI interpolation possible in SVP!!!

Interestingly I tried a 21:9 4h HDR video after the LG one at x3 and when in window mode it ran correctly. As soon as I double clicked to go full screen the film dropped to 9fps. Looks more like a configuration issue than RIFE as it was running fine windowed.

Re: New RIFE filter - 3x faster AI interpolation possible in SVP!!!

if any additional mb/s of data transferred can break things then everything is possible

make sure there is no other vapoursynth path in your system PATH.

Re: New RIFE filter - 3x faster AI interpolation possible in SVP!!!

BTW I was returning my watercooled 3090 back to stock today before selling on. I thought i'd give this latest version of Rife a go and it does run 4K HDR at 48FPS no issue.

So this isn't limited to 40 series cards. Power draw is low too, around 150w.
