VR6 10bit (HDR) support?

Any update on 10bit color HDR (HLG?) support? It looks like in the broadcast industry, HLG has basically won out. Nobody is doing anything beyond HLG in live linear broadcasts. Let me know if you guys need samples.

Yes, we could use a sample or two. Please upload them and send email to support so we can check them in.

Under the hood there has been quite a bit of work for 10-bit support, but it's not yet completed. In the current release builds, 10-bit video is down converted at decode time to 8-bit and the rest of the processing chain is 8-bit. We've removed this limitation so that the video remains 10-bit coming out of the decoders. The internal decoded frame formats now support formats from 8- to 16-bits. All the encoders, which are capable of supporting 10-bits, can output 10-bit encoded files.

What's remaining are all the intermediate filters such as chroma converters, resizing, deinterlace (does 10-bit interlaced exist?), etc. Then the glue for wiring this all together needs to be completed.

Done. Awesome. I would totally support HDR support being the the flagship feature for v7. Clip uploaded and e-mail sent to support - I've got lots more where those came from. From guys that are smarter than I am, they're apparently cutting commercials today via ffmpeg, but I'm not that smart.

@Danr Thanks so much for the update. I know it is a daunting task, having followed my expen$ive NLE through the last few versions, and there are still some holes in the filter chain.

One thing I might suggest, is including support for the blazing fast Magic YUV Ultimate encoder, which has put Premiere and Vegas intermediate users into the spotlight with developer plugin support for 10+ bits. He's really a nice guy, willing to write plugins for different NLEs, and the SDK is freely available. For mathematically lossless encoding, there is nothing out there that can touch it at this time.
