I actually read the documentation today and realized that a lower value for scene change threshold equals better detection. Setting this to 6% caused some scenes that were not detected before at 10% to be detected. But only the most obvious of scene changes. There does seem to be a difference in how this threshold needs to be set between HDR and SDR that might be worth looking into. Is it possible to support lower values than 6%?

I updated to the latest version using TensorRT and I noticed that scene changes still don't work with HDR sources. Scene changes seem great with SDR but HDR all scene changes are blended. Everything else seems to work great in HDR and RIFE.

I've noticed when watching HDR material with RIFE, scene changes are always blended/interpolated regardless of the value I put for "scene change threshold". If I watch SDR  (8 or 10-bit) I don't notice any frame blending on scene change.

I'm using:
* MPC-HC
* MadVr
* AviSynth Filter

Confirming a bug where the new RIFE AI in SVP as of the latest update seems to have removed color when playing back any video. Color is restored if I switch to SVP's standard method.

Tried with both 8-bit and 10-bit videos.

My videos have color when RIFE AI profile is enabled.

Ah, I figured it out!  I had "GPU Acceleration" turned off.  Once I turn that on then SVP doesn't convert the video to 8-bit.

Thanks for confirming that it shouldn't be converting to 8 bit.  That gives me a concrete improvement to work towards.  I've attached some logs.  LMK if they are the wrong ones.  The plugins and media player wasn't installed by SVP.  If you think a stock install of all that would help I can give that a try.

... which means you aren't using 10-bit output actually

Can you please help me understand what you mean by this?  I have "Allow output in 10-bit color depth" set to always.  Yet, in madVr stats it lists "l420,8 bit, 4:2:0" with SVP enabled.  With SVP "Temporarily Disabled" MadVR shows "P010, 10 bit, 4:2:0".  Is that what you are referring to? Do I have something configured wrong in SVP causing it to change the video from 10-bit to 8-bit?

My Display output is set to 8-bit in madvr.  But, I think I'd rather have madVR do the dithering over AVSF if possible.

Well, I'm sad that you couldn't duplicate the issue.  But, turning on dithering seems to have fix the problem anyway!  So, thanks!

However, with dithering enabled, when I watch an 8-bit source I get the error "dithering is allowed only for 10-16 bit sources".  Perhaps there is some way to only enable that setting if it is a 10-bit video?

Hmm....this problem doesn't seem to be exclusive to "Highlight Recovery".  I have a different set of settings (Highlight Recovery disabled) that looks fine in that clip of Croods 2 but produces banding in a different movie.  But, like the other banding, it goes away when I disable SVP.  If you want I can grab a clip and settings for that one as well.

So, I did a little more research and found that the banding was linked to enabling MadVR's HDR "Highlight Recovery" feature.  If I have SVP enabled and Highlight Recovery disabled then the banding goes away.  If I disable SVP and enable Highlight Recovery then the banding goes away.  If both are enabled then the banding appears.

Given the link to a specific MadVR setting, I'd understand if you didn't find it worth your while to research further.  But here are steps to reproduce it if you are interested:
* I'm using this version of MadVR: https://www.avsforum.com/threads/improv … t-60520084
* I'm using MPC-HC with AVSF
* I've attached an image of my MadVR settings that duplicate the issue.
* I've PMed you a link to the video clip.  Though I expect just about any HDR source will duplicate the issue with Highlight Recovery enabled.

Thanks!  Let me know if I can help in any other way.

Ah, I didn't notice that.  K, I'll do a bit more testing with a few other videos to see if I can narrow the scope a bit more and I'll post a sample of this.  Thanks, Chainik!

Same issue no matter how I set that 10-bit setting.  I'm using MPC-HC as the player and MadVR.  I think I only see the issue with 10-bit videos.  I didn't make that connection till I saw: https://www.svp-team.com/forum/viewtopic.php?id=6102

I'm fairly new to SVP.  I'm using the AVI Synth Filter with the latest Madvr.  I've noticed some banding appear in scenes that don't show banding when "Temporarily disable SVP" is enabled.  I've included some screen snips that will hopefully demonstrate it.  Look at the sky.  Any ideas?
