[DoVi_Scripts] Multi-Function Scripts for Dolby Vision processing and a lot more...

i dont know about a much faster preset but yeah, CRF-0 + slow preset should be lossless

Ran into an unusual error message for the first time yesterday! As I do often I was using the madVR HDR brightness measurement function, in this case on a rip of Dungeons & Dragons: Honor Among Thieves. I'd already plotted the Dolby Vision metadata without issue, but trying to measure brightness resulted in the following output:

For some reason, measurement didn't produce a "complete" file.
Reading generate config file...
Parsing madVR measurment file...
Error: The system cannot find the file specified. (os error 2)
Parsing RPU file...
Error: The system cannot find the file specified. (os error 2)

Then that error repeated several times and the process ultimately failed, leaving only a file in the source directory of the video file with a .incomplete extension. Retried it a few times with identical results.

Any ideas on troubleshooting?

Yes sometimes madvr fails to measure a video.

you can try converting to ProRes as a workaround.

I wonder if Dolby finally fixed the slow ProRes processing.

In the latest DV professional tools release notes:
''Corrects a latency issue when reading long QuickTime MOV files.''

Thanks for the suggestion. I actually got an error that halted the attempted ProRes conversion too, about clip length not matching the RPU.

I did eventually get things to work, so in the unlikely event anyone encounters my specific issue - when I ripped the disc via MakeMKV, there were two playlists that appeared essentially the same, but one had chapter markers included and the other did not. I originally ripped the version with chapter markers, which is the one that gave me all the errors. I re-did the rip and selected the playlist without chapter markers, and for whatever reason the madVR brightness measurement worked on that file immediately.

Sure looks like it. (1:47:00 long movie)

yep, looks faster on mine too.

running 3.12 BETA, have an issue with Lawrence of Arabia I've not encountered before. I joined parts 1 and 2 together with mkvtoolnix, my base HDR10 mkv seems fine. Ran 6-2 without issue, unsurprisingly not a particularly bright film, but I thought I'd run 3-1 anyway. I noticed that the initial call to ffmpeg showed some warnings: an invalid block message and could not find codec parameters for stream 2 (subtitle hdmv_pgs....) unspecified size. Then, the pro-res creation step ran at warp speed, and then I got an endless stream of messages featuring constant repeats of "skipping NAL unit 63". I quit and it looks like no proper prores file was created. Any ideas?

[Kuler087]

Sounds like a corrupted source. You could try converting it to prores without ffms2 but I doubt it will work.

Something odd here. Discs 1 and 2 of Lawrence of Arabia are DV. MediaInfo, Kodi and my TV all report DV when played from mkv. But if I open disc 2 with DoviScripts, it says it's HDR10, even though other tools identify it as DV. I must have seen that and assumed there was no DV at all. DS reports MEL for disc 1.

not much I can do without a sample... I dont have this movie, I hate old movies.
