AVS preview won't load - lostsnowboardvideos - 13.07.2025 Hi Selur, I can't get AVS preview to load any time I input an AVI file to encode. I use avisource for avi input but the file crashes. RE: AVS preview won't load - Selur - 13.07.2025 If the preview does not work, neither will the encoding.

When using LWLibavVideoSource with YUV422P8 it works fine. I will look into it. Cu Selur RE: AVS preview won't load - Selur - 13.07.2025 Since I don't want to spend hours figuring out where the problem in QTGMC.avsi is, I adjusted Hybrid to not use YUY2 with QTGMC, which will tell Hybrid to add: ConvertToYv16(interlaced=true) to the code, which fixes the problem. (a better solution, might be to fix QTGMC.avsi, but that can be done by someone else) => uploaded a new dev with this change Cu Selur Ps.: Why are you using Avisynth at all? None of the filters you use is only available in Avisynth. RE: AVS preview won't load - lostsnowboardvideos - 20.07.2025 Thanks! Was using CCD in avisynth and didn't realize there is a VS plugin now for it. Although it reduces speed. RE: AVS preview won't load - Selur - 20.07.2025 Assuming your CPU supports AVX2. You can try the latest dev, it includes CCD support through the zsmooth (which added it recently). Not sure how fast that is compared to the Avisynth version, but it's faster than the Vapoursynth script used before. Cu Selur
