This bug seems to be fixed.
Optical Flow seems to be working on Ampere now with the last update.
> I recently got an RTX 3090. It used to work fine a few months ago.
to be clear: 3090 used to work fine a few month ago, right?
then what if rollback to the rev.196 svpflow plugins: https://www.svp-team.com/files/repo/ful … ugins64.7z (overwrite files in SVP 4\plugins64, backup existing rev.202 first)
No, I had an RTX 2080 Ti, but don't know whether Optical Flow was working even on that just before I upgraded to the RTX 3090. I know only that it worked on the RTX 2080 Ti some months ago.
The image is almost completely corrupted with those DLLs, but I could make out that interpolation was still not working.
Putting back the original DLLs fixed the corruption and reverted to the old behaviour where interpolation works in simple scenes and stops working in complex scenes.
I just realized you can change the settings in the main control panel with a new profile.
I tried the various "Motion vectors grid" values, but there was no difference. The strange behaviour based on scene complexity is still true.
I created a new profile "Test" as a copy of "Automatic" and was able to change the "nvof_" values in that profile. I selected the "Test" profile during playback.
I tried different values of "nvof_grid" such as 12, 16, 24, 48, and 64, but there was no difference.
I tried changing "nvof" from "-1" to "1" in the profile but it had no effect.
Changing "mv_grid" also had no effect with Optical Flow enabled.
However I noticed something strange while testing. With Optical Flow enabled on default settings, it randomly works for a few seconds while the scene complexity is low. During a panning shot, the video becomes smooth with interpolation while the background is simple, and when the background becomes complex, interpolation stops.
try different "motion vectors grid" values
The "nvof_grid" value is read-only under "rt>generic". It's editable only in the 3 pre-defined profiles. Where do I set it to override the "Automatic" profile?
and with Utilities -> Fluency and tearing test enabled - do you see the yellow line?
With Optical Flow enabled, there's a red line and it appears to be moving at 120 fps even though interpolation does not work on the video itself.
With Optical Flow disabled, the line is still red but interpolation works.
then check log for errors
No errors in the log. I toggled Optical Flow on & off while the video was playing.

What about FullHD videos? Do you see lag and stuttering there?
It does not work in any video of any resolution. Testing it right now, it's not an additional stutter. Interpolation just doesn't work at all when Optical Flow is enabled, and the video runs at the original frame rate. If I disable Optical Flow, interpolation starts working.
This is still broken.
I don't notice a difference between interpolating 24 fps content to 60 Hz and 120 Hz, so 72 Hz will not be a visible improvement. The difference between 60 Hz and 120 Hz is noticeable only in interactive content like games. Maybe native 120 Hz content will appear smoother than 24 Hz interpolated up.
There is a slight advantage to having a perfect 3x multiplier, but again the difference is not noticeable with interpolation, unlike the judder from 3:2 pull down when watching 24 fps content at 60 Hz without interpolation.
If I open a video with Temporarily Disable SVP checked, madVR is unable to detect the BT.2020 primaries and uses BT.709 resulting in incorrect colours. I must uncheck & check Temporarily Disable SVP while the video is already playing for madVR to detect the BT.2020 primaries.
I'm using the new AviSynth Filter. This is a major annoyance when watching movies with my LG CX's motion interpolation instead of PC mode with SVP.
You can also use the new AviSynth Filter which supports HDR with madVR, instead of ffdshow. Then you can use madVR's higher quality HDR to SDR tone mapping.
Same issue even in mpv without madVR.
What is the purpose of the frc > color > hdr > max_luminance setting? The default value is 1100.
Is this going to limit the maximum luminance of the image in HDR videos?
Enabling NVIDIA Optical Flow now causes severe lag and stuttering. If I disable it, the video is smooth again. I'm not sure when the issue started. I recently got an RTX 3090. It used to work fine a few months ago.
Windows 10 x64 20H2 Build 19042.610
MPC-BE + AviSynth + madVR
mpv
4K 120 Hz HDR
I found that 2160p 10-bit Blu-rays stutter at 120 fps but are smooth at 90 fps in mpv. Other lower bit-rate 2160p 10-bit videos are smooth at 120 fps. I don't see any meaningful increase in CPU / GPU usage between the two, so I don't know what the bottleneck is.
1. I currently use a Predator X27 with HDR permanently enabled in Windows.
2. i9-9900X @ 4.6 GHz
3. Yes, but now at 4000 MHz C18 since I changed the motherboard and the new one can't do C17.
4. mpv configuration:
input-ipc-server=mpvpipe
hwdec=d3d11va-copy
hwdec-codecs=all
vo=gpu
gpu-api=d3d11
gpu-context=d3d11
profile=gpu-hq
hr-seek-framedrop=no
save-position-on-quit=no
ao=wasapi
# audio-exclusive
audio-spdif=ac3,dts,dts-hd,eac3,truehd
audio-channels=autoI've enabled 10-bit output and disabled HDR colour recovery in SVP. mpv plays HDR correctly but stutters if SVP is enabled. MPC-HC + madVR plays HDR with the "hdr=on" filename tag, but madVR uses BT.709 making the colours slightly inaccurate.
It does now if HDR is enabled in Windows.
HDR works with the latest update, but it stutters constantly when SVP is enabled, even if frame rate conversion is disabled. SVP must be disabled to stop the stuttering.
HDR works with the latest update, but it stutters constantly when SVP is enabled, even if frame rate conversion is disabled. SVP must be disabled to stop the stuttering.
I'm running quad-channel 4 x 8 GB 4000 MHz C17 so memory bandwidth is not a problem. The CPU usage stays the same as 8-bit at around 14%, but 10-bit stutters severely.
Here is my MPV configuration.
# this is required for SVP to "catch" the mpv
input-ipc-server=mpvpipe
# hardware video decoder
hwdec=d3d11va-copy
hwdec-codecs=all
vo=gpu
gpu-api=d3d11
gpu-context=d3d11
# high quality video output, require rather fast video card
profile=gpu-hq
# use ANGLE if you have problems with default d3d11 renderer
#gpu-context=angle
# OR the newest VULKAN API
#gpu-api=vulkan
# miscellaneous options
# fixes audio desync
hr-seek-framedrop=no
# this can't be used with SVP cause it also saves vf's states
save-position-on-quit=no
# "ReClock" replacement
#video-sync=display-resample
#video-sync-max-video-change=5
#log-file=mpv.log
ao=wasapi
audio-exclusive
audio-spdif=ac3,dts,dts-hd,eac3,truehdVLC is also not smooth with 10-bit when SVP is enabled.
at least much less than before
I'm still unable to play 10-bit 4K videos without severe stuttering on an i9-9900X @ 4.6 GHz and RTX 2080 Ti with Optical Flow. If I merely disable 10-bit output in SVP, MPV plays smoothly. MPC-BE plays 10-bit smoothly with SVP.
