Dolby Vision now possible through MP4 Mux.

there might be some devices that use L6 when they decode DV as HDR10 but otherwise, it's pretty much useless.

Thanks very much!

Sorry, follow-up question. If you're watching DV content, with updated L6, on an HDR10-only device. Does it even matter? Or is it only something that a DV device can use? And if you are on a DV-capable device, and playing back in DR10, is it better to update the L6 or not? Sorry... I clearly need to do more reading on L6.

Appreciate the guidance!

If you're watching DV content, with updated L6, on an HDR10-only device. Does it even matter?

if the device sends the static L6 metadata to the TV, yes. For example, on the ugoos, unless you specify an HDR10 string in the menu, it sends LLDV in HDR10 without static metadata which is not ideal. Preferably, you want to send a maxcll or MDL value that matches your EDID target so the TV can use the best static tone mapping curve for the image brightness it receives.

However, it also depends on whether your TV uses MDL or maxcll for HDR10.

Here's a DV profile 4? (SDR HEVC BL?) file I came across from someone linking on Plex forums:

Trying to export FEL screenshots without an nvidia gpu but it's not working. It says that it exports the screenshots but the folder doesn't have any in it. I downloaded the latest tool pack and ffms2 is in it, so any idea what's going on here?

[RESET_9999]

idk, did you install avisynthplus ?

Yep. Just reinstalled to verify. Still no screenshots

[RESET_9999]

idk , works fine for me. Try in manual mode, go into the temp folder and try to play the .avs script in avspmod, it will tell you the error.

[DylanValenti]

It says "Cannot load file 'Z:/01DoVi/tools/avs_libplacebo.dll'. Platform returned code 126: The specified module could not be found. (Z:\01DoVi\temp.folder25\9_FEL.avs, line 2)"

I checked my tools folder and avs_libplacebo.dll is indeed in the root. Any suggestions?

[RESET_9999]

no idea, works fine for me but i just noticed that there is an issue with the HDR10 Base layer SDR tone-mapped screenshots in that workflow which is unrelated to your issue and is now fixed in latest beta. Anyway, I dont see the point in comparing HDR images in SDR(this is not lossless). The script outputs proper HDR metadata for the HDR screenshots which can be viewed in HDR (or mapped to SDR) on Chrome/Edge/Opera browser. EG: https://slow.pics/c/bTBjYZuB Also, ffms2 for my screenshots workflow (7-1) is quite slow so not really usable IMO. When you encode in 8-2-1, it's fine.

I'm removing this, MEGA started throttling my account ever since I posted it lol - I can't download my 8K movie trailers that get posted to MEGA because of 'account usage'

Edit: It's from here - the 'LG' one IIRC - https://www.demolandia.net/4k-video-tes ... age-2.html

[RESET_9999]

Yeah, I have speed issues with MEGA all the time. I hate it.

FWIW, when that happens to me, I just briefly turn on VPN and it seems to usually let the file download fast again, at least with JDownloader2 and a paid MEGA account. Cheers.

[staknhalo]

a paid MEGA account

Appreciate the tip though
