@Howard-Vigorita Are you using the free version of Resolve, I think I always assumed you had studio like a few others here, I wonder if your lower quality encoding results are somehow the cause of software decoding? But interestingly I did see that

RE: VEGAS PRO 22 HAVE THE WORST AV1 DECODING: CHROMA SUBSAMPLING 4:1:0

Great points, good to understand limitations of such metrics in mind. It sounds like on your and UltraVista's system VEGAS may be using the same AV1 decoder despite user settings. MxCompound seems to be able to call upon multiple GPU and software

VEGAS PRO 22 HAVE THE WORST AV1 DECODING: CHROMA SUBSAMPLING 4:1:0

Magix Vegas Pro 22 has a big serious problem: It decode videos with AV1 codec with Chroma Subsampling 4:2:0 as if it had Chroma Subsampling 4:1:0 It is imperative that the Vegas Pro developers know about this. This issue simply ruins the work of

RE: Question: 8 vs 10-bit HEVC Renders?

Do we get a 10-bits-per-pixel option in AV1 in the Vegas beta? I don't see that in the current build of VP22. Here's more (from ChatGPT) on the subject: https://chatgpt.com/share/67f13b63-b86c-8002-a1e9-bf1ec14f2785

Yes, VEGAS does override user choices at times, though I would think it would show up under decoding activity. Sorry about the poor instructions for finding the decoder. While holding down shift, right-click on media, go to properties, click on

RE: My Journey To AV1

Thanks Bruce, I am using MP4 AV1 (replaces H265). I am aware that H266 is starting to make an appearance but is much more intensive to encode and decode. I take your point about lossless ProRes, I must see what file size I get with it.

I usually upload song-renders to YouTube made with MainConcept 4k hevc-vbr 28/56mbps 10-bit. Would really love to switch to Nvenc Av1. Voukoder and Resolve seem stuck in a similar 4k quality rut... odd that they both use ffmpeg7 libs and come

P.S. Sure AV1 is more modern, with more features and so provides better quality. I'm not arguing that. To me it's not better quality, but just same quality at lower bitrates/smaller filesizes. It's all about keeping the quality of the original
