Re: Dolby Vision now possible through MP4 Mux.

I'm a bit confused since in your updated video on how to generate Dolby Vision and HDR10+ via Davinci Resolve you explicitly mentioned that L2 trims must be removed in order to achieve the most "natural" and near-creator-intended look possible. What has changed? I knew this question would...

Re: Dolby Vision now possible through MP4 Mux.

Similar to how it's important to sync web DV frames to match a bluray BL, are there tools to do the same thing to build an HDR10+ hybrid? I don't see any mention of it in hdr10plus_tool.

Re: Dolby Vision now possible through MP4 Mux.

For dovi baking (8-6-1), are we required to crop to match the image aspect ratio? Aside from the black bars being left in, does not cropping affect the encoding? One reason I ask is because I can't crop with an odd top/bottom number (263/263) on my video file, so I'm forced to crop with 264/264. Cro...

Re: Dolby Vision now possible through MP4 Mux.

Thoughts on using a 2000nit MDL? It has a decent amount of scenes over 1000 nits. 4000 seems excessive though, so I'm between 1000 and 2000nit MDL for Resolve DV analysis. TIA :) You should update your script, I added more information that makes the decision easier. My initial recommendation was if...

Re: Dolby Vision now possible through MP4 Mux.

2 options: 1- just use the static metadata from your source HDR10 2- check the brightness first with madvr. If 95% of the movie is under 1000nits, use 1000nits MDL else, 4000. Option 2 is better because some movies have a static MDL of 4000nits but the actual brightness is under 1000nits. A 4000nit...

Re: Dolby Vision now possible through MP4 Mux.

Quick question; when generating CMv4.0 content (3-1), how does one determine what Mastering Display to use? I assuming higher isn't necessarily better? 2 options: 1- just use the static metadata from your source HDR10 2- check the brightness first with madvr. If 95% of the movie is under 1000nits, ...

Re: Dolby Vision now possible through MP4 Mux.

For injecting both HDR10+ and DV into the same BL, does it matter which you do first?

Re: Dolby Vision now possible through MP4 Mux.

Is there a consensus on whether the new algo is better than Resolve, or is it more preference on how dynamic we want the DV? My personal take : that is like asking do experts all agree that modern phones or cars are better than older models, of which you'll always get differing opinions (this even ...

Re: Dolby Vision now possible through MP4 Mux.

CM_Analyse with L1 tuning is the latest version of the Dolby Algo which evolved a lot since Dolby was created. It went from fully dynamic with very aggressive/higher L1 values to lower & less dynamic metadata(10nits/1000nits floor). I wonder if they did that because of the complaints you often ...
