From 6b549b7e4fcdc8792e66741b4e1490ba3f2606f4 Mon Sep 17 00:00:00 2001 From: dotCooCoo Date: Sat, 24 Oct 2026 14:53:37 -0700 Subject: [PATCH] Docs: Cineon Settings white point converts exactly only without Highlight Rolloff The footage page said the 10 Bit White Point becomes the Converted White Point. That holds with Highlight Rolloff at 0; at the default 20 the top of the converted range is bent into a curve, as in the Cineon Converter effect, and the white point converts to a lower level. --- docs/footage.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/docs/footage.md b/docs/footage.md index bd2f47e31..4596a8546 100644 --- a/docs/footage.md +++ b/docs/footage.md @@ -94,7 +94,7 @@ used, and layers that ran to the end of the footage keep doing so. | Fields, pixel aspect, loop | As in After Effects. | | **Assign Profile**, **Interpret As Linear Light** | The colour profile the file's values are in (the working space converts from it), and whether they are linear light. | | **Preserve RGB** | The file's values enter the composition unconverted: no colour profile, linear light or working-space conversion, and float files (OpenEXR, float TIFF) keep their linear values instead of being sRGB-encoded.
