hdr=none prevents HDR10 from being displayed twice in the mediainfo
i've seen this, is that the only thing it effects (mediainfo redaout)? is playback effected at all on anything?
I can't tell the difference between quality from my eyes. So I just don't bother to change it.

Code: Select all
mp4box.exe -add "%BL%:hdr=none:dv-profile=8.1:xps_inband" -add "audio" -add "subtitle" -brand mp42isom -ab dby1 -no-iod -enable 1 "output.mp4"
Hi, I'm curious about what does `-ab dby1 -no-iod -enable 1` mean?
Will they affect final quality of the image?
Could you please explain a little bit more of this, thanks!

Understood! Thanks for the clarification, I'm giving it a test now. I also own an Apple TV and can test if the fake P5 works. Is there a specific player that its been said to work on like Infuse?
Apple's native player or any player that "passthrough" that file to Apple's player core. Avoid using INFUSE.
I play them in "FILE" App directly SMB from my PC.

Also do you guys know if there is an option in mp4box to convert dvhe->dvh1 when importing mp4?
Currently I'm using:
ffmpeg -i dvhe.mp4 -c copy dv.hevc
mp4box -add dv.hevc -new dvh1.mp4
But it would be nice if I could just skip the ffmpeg step.
Thanks.
The command is:
https://github.com/gpac/gpac/issues/199 ... 1262491409
Code: Select all
MP4Box -add source_dvhe.mp4:dopt:xps_inband=no -new source_dvh1.mp4
Also if anyone is interested, the latest mp4box auto detects DV Profile now, instead of tag everything as P5 dvh1.
