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

dovi_script does not support AV1 (I could add support eventually), but you can still use it to generate the FEL Baker AviSynth script and then encode to AV1 using a GUI like StaxRip.

1- Run 8-2-1 and cancel the process as soon as the encode starts.
2- Go to the dovi_script TEMP folder and import ''script.avs'' into StaxRip. From there, you can bake the FEL and encode directly to AV1.

*It’s also possible that StaxRip now supports FEL directly, but I haven’t followed its development recently.

I get this error when I drag and dop the scipt.avs file into Straxrip and select automatic:

Script Error

You have to change your staxrip project to avisynth.

hello
i'm trying to inject your L5 offsets data in the rpu of interstellar.
copy the text into a samename.json file
everything good except at the end, i've this message

01/13/2026/20:29:54.198000000 metafier: ERROR Illegal Per-frame Level Data: 5

do you know what it is ? ERROR illegal per frame

thank you

[Kuler087]

It means that some L5 change happens on a frame that is not a scene cut.
Is this the json edit you've used? I just checked my RPU, and everything is fine.

it's this one

https://justpaste.it/bhv73 from your excell sheet

my last frame is 243218

EDIT : ok if i change the last line with "235848-243217": 0

Yeah, my RPU frame count comes from the WEB-DL before it’s injected into the Blu-ray remux, which automatically duplicates frames at the end to match the video length.

Other than that, there’s no difference with that JSON, so you shouldn’t be getting a Metafier error. Are you using an older version of DoVi_meta.exe? I know that a while ago, it had an issue when converting RPU to XML, which caused this kind of error in Metafier.

[dkangel]

no everything is up to date, dovi script 3.1.0 with last tools directory

it seems ok now with changing the number of the last frame

if i put 243217

This movie trim pass is useless, FYI. You'll get better quality if you generate new CMV4.0 metadata.

[dkangel]

ok i will do that with resolve, is it possible to import your l5 metadata in resolve to avoid all the cuting stuff ?

[Kuler087]

No. You can only import the scene cuts, but not L5.

You can use my Resolve project:
with homemade trims: https://drive.google.com/file/d/1M1t...usp=drive_link
without trims: https://drive.google.com/file/d/1Vrm...usp=drive_link

[dkangel]

ok i'll try this tomorrow, thank you for your time

[dkangel]

i've import your project with my mov file, scene cuts are ok and so L5 changes seems synchro too, i'm analysing for dv and give a try on my tv
but i think it will be ok

For a native DV Blu-ray rip, some FEL titles do restore a brighter master, but that benefit is lost once they are converted to Profile 8. You need a device like the Ugoos Am6B+ to get that brighter DV from FEL playback.

Baking in the FEL properly to get a p8 is still lower on the picture quality scale than a Web p5 (due to the color space), correct?

[Kuler087]

yes but streaming DV5 has worse hevc compression due to the lower bitrate

Damn, so what do you choose? I suppose whatever looks pleasing to the eyes on your display?

I guess p8 remux > p5 > p8 encode

[Kuler087]

When compressed properly, a P8 encode will be better than streaming DV5.
remux > p8 encode > P5

No kidding, does that mean if the p8 encode and p5 are identical bitrate you'd go with the p8?

Thanks in advance.

[Kuler087]

If the P8 encode comes from the UHD Blu-ray and I compressed it myself, yes.
Streaming compression is subpar. iTunes is DNR garbage, MA has a lot of compression noise and introduces visible artifacts with grain-heavy content, Disney’s and Fandango bitrate is too low, and Amazon’s HEVC compression is horrible.

Interesting note about MA, everything else I've read about it is exceptional and potentially equal/better than the UHD disks.
