Re: Dolby Vision now possible through MP4 Mux.

Life is busy, havent been able to monitor the development of DV. Can someone explain why is it a big deal CMv2.9 vs. CMv4.0? I see the latter mentioned a lot here. I read the official document, but dont understand why its a big deal. Thanks! CM v4.0 provides creators more control over tone mapping,...

Re: Dolby Vision now possible through MP4 Mux.

what is a dual-track and dual-layer exactly? can someone describe in simple terms? Dolby Vision is really complicated, you may want to do more research to learn how it actually works. In human words: BL(base layer): an HDR10 2160p YCbCr 4:2:0 10-bit video. Dolby Vision fall back to this when not su...

Re: Dolby Vision now possible through MP4 Mux.

You've noted that P5 > P8 due to the colourspace being equivalent to 11.5-bit YCbCr > 10-bit YCbCr. Is there a noticeable difference between P8 and P5, assuming that it's the same master/streaming quality, on consumer-grade 10-bit panels ? Difference, yes. Noticeable, no. https://www.avsforum.com/t...

Hi guys, any FEL P7 sample available to donwload? Thanks.
Under @RESET_9999's signature DoVi Playback Devices, select DoVi TEST FILES/PATTERNS, and FEL TEST is there. It's a little hard to find.

Re: Dolby Vision now possible through MP4 Mux.

Does anyone know of any software that can losslessly splice P5 DV HEVC streams while keeping the P5 DV metadata in tact? Splicing on I-frames, obviously. You could try: ffmpeg -f concat -i "filelist.txt" -c copy -strict -2 test.mp4 filelist.txt: file 1.mp4 file 2.mp4 I won't guarantee it ...

Re: Dolby Vision now possible through MP4 Mux.

Has anyone figured out how to convert P5 MKVs to MP4? I've tried an FFMPEG command found here: ffmpeg -i "S01E01.mkv" -map 0:v -map 0:a -map 0:s:0 -c:v copy -c:a copy -c:s mov_text -strict unofficial "S01E01.mp4" That command seems right. Make sure you are using the latest tools...

Is there an easy ffmpeg command to convert an .mp4 with embedded DV (profile 5) to .mkv?
Looks like ffmpeg doesn't support dvh1 codec in mkv.
Try something like:

Code: Select all

ffmpeg -i dvh1.mp4 -c copy -vtag dvhe dvhe.mkv
I don't know if the mkv will play proper Dolby Vision though.

no i think the OS HDR always sends incorrect static HDR10 metadata.
ok thanks, at this point I think I'm giving up on playing movies on PC.

Re: Dolby Vision now possible through MP4 Mux.

If I'm right, it looks like if I want to play video correctly in Movies & TV, I need to either set EDID to 10000nits and let my TV to do the tone mapping. Or disable tone mapping on TV and set EDID to 0-1350nits and let windows do the tone mapping. Since Dolby Vision Extensions is unlikely to w...

Yep, LLDV is useless without a custom or original edid with min target 0 and I bet its the same reason why all LG TVs has raised black since their internal config file is not 0.
Is that normal both my Oled G8 and S95Z don't provide Max/Min luminance in the EDID HDR Static Metadata session?

Re: Dolby Vision now possible through MP4 Mux.

Hi RESET, I still notice raised black level when using Microsoft Hardware Video Decoder in the Energy player. I think I find out what's going on here. My theory is Win11 expects us to play everything under HGiG mode, gaming, streaming, playing local files. It wants us to disable tone mapping on dis...

Re: Dolby Vision now possible through MP4 Mux.

as I said, in LLDV player led if your edid min target is not 0, you'll get raised blacks. I replicated on my C2 too, if I use the default c2 edid its raised, if I use a custom edid with min target set to 0 and reboot, then black is black. My C2 is in a room with black velvet on floor ceiling and wa...

Re: Dolby Vision now possible through MP4 Mux.

Yes, you're right. I couldn't see it on my Samsung monitor because it's in a bright room but on the C2 I can see the slightly raised blacks. QD-OLED will lit up by ambient light, I tend to use it in a dark room. G9 is really wide... The problem seem to be the Microsoft HEVC extension because it's a...
