Colour Banding on Vulkan Builds

Closed this issue 9 days ago · 8 comments

Hello, I am seeing colour banding / video compression artefacts on videos when building with AVPro 3 and Vulkan that are not visible on the real video. The issue isn't present on OpenGL builds and is not present in the editor (DX11).

Unity version: 2022.3.39f1
AVPro Video version (number and edition (trial/core/ultra/enterprise)): AVPro Video v3 - Core Mobile Edition 3.0.8
Device model: Nokia G42, Pixel 6, S23 Ultra
Video specs (resolution, frame-rate, codec, file size): 1920 x 1080, H264 - MPEG-4 AVC (part 10) (avc1), Frame rate: 30

To Reproduce

Create blank project and import AVPro 3 Mobile 3.0.8 with demo scenes.
Ensure graphics API is Vulkan.
Add the attached video into the AVPro 3 Demo_Playlist scene.
Build and run on android device.

The banding is not seen in editor or when using OpenGL.

Thank you.

There's an issue when converting the video output to linear colour space. This has now been fixed and will make it into the next release.

Thank you very much for fixing this. My team and I are looking forward to using the new version with this banding problem solved.

Thank you! I'll look out for the new release.

Is it at all possible for us to fix this issue in some way before this release? We are just prepping a major release for next week and it includes the new av pro sdk? Please let us know if any methods exist? We won't be able to wait for this sdk version to release our build so we need some sort of fix in advance.

@TrippingDan

The fix for this issue is at plugin level, so there is no way you can apply it without us compiling up and packaging a new asset release package.

We only have a mechanism for providing interim version packages for Enterprise license holders. If you are from a company that holds an Enterprise license then simply ask the main point of contact from your company to drop us an email and we will sort out a build containing the fix asap. If you are not, then I am afraid you will have to wait for the next update - which we have penciled in for the end of this week.

Apologies, but if we provided custom versions for every license holder we would never have time to fix bugs and add features!

AVPro Video v3.0.10 has now been released. Do let us know if this fixes the issue for you.

Thanks for letting us know @TrippingDan . If you have 5 minutes free, it would really help us out if you could leave an honest review of the asset (and support) on the Unity Asset Store. Thanks!
