Nothing can make single layer DV from original dual layer of UHD bluray without decrease in quality. Because original streams/layers are encoded in HEVC which is "lossy" codec. Once you unpack/decode and re-encode, there goes your quality.

CloneBD works well with Dolby vision, it even can compress to a smaller file size, but it creates a Dolby digital track with audio description for people who are blind. So a man is telling what is happening on screen. I can not choose a different audio track. This happens with te uhd bluray of Cold...

Is it possible to encode a Dolby Vision mp4 mux to a smaller file size? When i try to do with handbrake i lose the Dolby Vision layer. And btw thanks for this great program! I'm using it a lot and works great! Technically I don’t think so at the moment. DV is only possible with original Blu-ray and...

@tango306: Glad I was able to provide with good info and help clarify things. Didn't look that deep into the matter, did know your fist 3 facts, not the last 2. Do have a question for you: I read u used CloneBD to merge 2 m2ts files together and convert to mp4... Was CloneBD the only tool u used fo...

A question for this MP4 muxing. I've just ripped Star Wars Last Jedi 4k bluray disc, and to play from beginning to the end, it plays two m2ts files. The first 3~5 minutes: 00007.track_4113.hevc (base layer) 00007.track_4117.hevc (enhancement layer) 00007.track_4352.ac3 The rest of the movie: 00018....

Hi tango306, Read your discussion with Grencola... I'm having trouble creating good mp4 from mkv. Been reading on this forum for that and it's hard ignore the discussion :P ...I was wondering why u think original UHD Dolby Vision Blu-ray discs are 12-bit? Or did I misunderstood? A few months ago (w...

I was sticking up for the mp4s a bit cuz you said, "And if somehow 12-bit is degraded into 10-bit in muxing process, who know what else is borked in the chain." but nothing seems to be degraded in the chain was all. Well then, *if* what Oppo-203 is reporting is true, what makes DV's nativ...

12-bit contents looks better than 10-bit contents even on 10-bit panel just like 4K contents looks better than 1080p contents even on 1080p panel. That being said, if this muxed DV MP4 is degraded from DV's native 12-bit to 10-bit, we are not seeing a true DV. And if somehow 12-bit is degraded into...

You are missing the point and do not understand the benefit of DV. 12-bit source and signal shows improvement on 10-bit panel. Period. This has been proven many times if you search. Now, back to my original question, is DV muxed into MP4 container, degrades in any way or form when played back on DV...

Hi folks. I was reading a discussion on Reddit where a member comments that on his Oppo 203 when playing one of these MP4 DV remuxes it reports the video stream as 10-bit, however if he plays the same movie from a full disc copy (including BDMV folder) that it reports the video stream as 12-bit. ht...
