Will Converting to DV8 have any effect on HDR10+ Data #21
-
|
Hi there! I have some movies I've ripped from my Blu-Rays that have both Dolby Vision (MEL) and HDR10+ data. For the MEL movies I'd like to convert them to DV8 to save a (small amount of) space and increase compatibility with various devices that can play DV8, but not DV7. But I'd also like to preserve the HDR10+ data if possible. I'm sort of assuming that won't really be touched in converting the Dolby Vision portion, since for most titles HDR10 data stays there as a fallback, but I wanted to confirm if anyone knows if that would be the case or not. Thanks! |

HDR10+ should survive as-is. There's a As a sidenote, DV dynamic metadata and HDR10+ dynamic metadata can both exist alongside HDR10 static metadata, but they are all used separately. They coexist for playback systems to decide what to use. So the fact that the HDR10 data survives untouched doesn't really have any bearing on whether HDR10+ metadata survives through the process. |

Great! I figured as much, but wanted to be sure. Thanks! |

There's a
--drop-hdr10plusoption that works with the variousdovi_toolcommands, and since that option isn't being used in theDV7toDV8script, HDR10+ metadata should stay intact through processing.As a sidenote, DV dynamic metadata and HDR10+ dynamic metadata can both exist alongside HDR10 static metadata, but they are all used separately.
