Colorspace clipping using add blend modes in OCIO v25.2.2

Apr 23, 2025 Apr 23, 2025

Hi,

Just upgraded to 25.2.2 and I am having a strange issue with adding layers its like it randomly clips or switches color space from one frame to the next. Only started happening after upgrading AE and NVIDIA.

The screenshots are from the same project just different frames, as you will see it also affects the scopes. Only effect used is 'Fast Box Blur'

Switching to 'Software Only' fixes the issueScreenshot 2025-04-23 131637.pngScreenshot 2025-04-23 131655.pngScreenshot 2025-04-23 131835.png

Thanks for sharing the files and details. I am able to reproduce the issue on my end. However, it's different on my end. The values are clipped the whole time as shown in your screenshot at the bottom. The Scope looks not clipped on specific frame if I change the value of the Fast blur on any layer. If I disable the Fast Blur, it seems to be working fine. I've filed a bug for further investigation. Thanks for reporting.


Thanks,
Nishu

Does anyone know if there will be a fix soon? We've been stuck with After Effects 25.1.0 for a while now...
