Topic: Rife scene change detection not working with hdr?

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

Re: Rife scene change detection not working with hdr?

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.

Re: Rife scene change detection not working with hdr?

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%?
