I have did comparison of a movie from iTunes (4K Dolby Vision) with a UHD 4K remux (converted from DV7 FEL to DV8) and did not spot any difference between these two versions if comes to brightness, colours and shadow rendition. I used DV7toDV8 utility for macOS that removed FEL metadata from RPU so the final image was the same like the streamed version.
That means the blu-ray didn’t have a base layer mapped to a lower brightness.
Lots of features missing, and removes CM v4.0.
Hi @Sprites. Yeah, DV7toDV8 is still working as intended.
DoVi_Scripts has a lot of capabilities to support different scenarios, where my app has a smaller focus of converting DV7 to DV8.
How do you mean? The app fulfills its stated purpose. It converts DV7 to DV8, preserves the EL+RPU for archiving, plots the RPU graph, optionally strips unneeded audio and subtitle languages, and will additionally convert DV8 to DV8 if you just want to remove the CMv4.0 mappings.
The latest version 0.6.0 does not remove CMv4.0 (for those who have the latest ATV 4K’23), and version 0.5.0 strips CMv4.0 (for those with earlier hardware).
What is it you want the app to do?

It’s not a port of DoVi_Scripts, that’s all I was saying.
Please share the mediainfo as well (of the blu-ray version).
Hi @james - Looking at the upcoming features, looks like DV 8.1 support for ATV 4K’21 has been dropped from the roadmap. Has support been abandoned?
This is still on our radar. Thx.

For those using the DV7 to DV8 app on macOS, I’ve added an update with a GUI for easier access to the supported settings:
- Audio & subtitle languages
- Keep/remove DV CMv4.0 metadata (to support both ATV 4K 2021 & 2023)
- Keep/remove working files generated during processing
- Using the bundled tools or those installed on the local system
The settings stick across runs of the app and there’s an option not to ask again.
Let me know if you run into any issues.

If you remove working files does it still keep the image output?
Yeah, there’s no change in behavior for that option. I’m not considering the image to be a “working file”; it’s part of the output of the program for you to verify what happened.
If I’ve purchased a 4K Blu-ray and ripped the disc, I want to convert the DV7 file to DV8, and see an image of the RPU that was included in the output to verify what I’m getting.
Then I want to archive 2 files: the mkv file with the BL+RPU and the hevc file with the EL+RPU, so I’m not wasting space with full DV7 and DV8 copies of the same movie. All that’s duplicated is <100MB of RPU metadata.
If I want to watch the full DV7 movie, all I have to do is demux the DV8 BL+RPU hevc stream, then remove the RPU, then open tsMuxer and add the BL as first video stream and the EL+RPU as the second video stream.
