DV FEL is 12bit 422 delivered as 8bit 444 via RGB tunneling. You read the profile white paper which (only) describes each layer.dapope wrote: ↑Sun Dec 20, 2020 2:12 pmVery interesting, I would like to know where you learnt this since the public Dolby vision paper doesn't really make mention of this at all. In fact, while it does mention FEL it doesn't actually describe what FEL means. But it only lists profile 7 as 1:1/4 (4:2:0.) and makes no mention of either 12 bit colour or 4:2:2.
Either way, through 12 bit colour (theorized to make a small improvement to gradients when downscaling to 10 bit panel) or higher colour resolution, FEL profile 7 is slightly superior to 8.1.
all incorrect. It is like I wrote. Just read up on DV.lexyz wrote: ↑Sun Dec 20, 2020 2:12 pmWow. Hold on Looks like you overtheorize a little
p7FEL is 420 as well as p7MEL, or p5, or almost any other video (except some 422 HD sattelite streams)
FEL is more bitdepth only, it doesn't add color resolution
p7FEL 422 is upsampled from 420 by player . Same for regular 420 HDR or SDR
FEL is a Full Enhancement Layer (guess where that name comes from ?), all layers (BL or EL) are 420 as that is the Bluray spec, but a FEL (NOT a MEL) contains difference data that when combined brings the signal to 12bit 422. (this is Dolby's true IP in HDR and the one and only reason why DV will win the HDR format war)
Guess for the whole reason of that thread on bluray.com.... ?shawnc22 wrote: ↑Sun Dec 20, 2020 4:19 pmHere's a good read again on FEL v MEL for anyone interested: https://forum.blu-ray.com/showpost.php? ... tcount=119. I have also never heard of FEL automatically being 422, would like a source for that if it's true.
they're listing all the FEL titles so that users know what they'll get when they buy the DV version of the same old movie they've seen already 100 times... FEL in 12bit 422 may be worth the investment.
