Using the Secondary Color Correction in the Three-Way Color Corrector, I'm getting various white shapes moving around on screen. If I set "Soften" to 0, they go away. However, I need soften on to reduce the normal noise artifacts from the grading I want. Here is a screenshot: http://i.imgur.com/9JgokMN.png
The issue is consistent. The white shapes move as I change the Soften setting. Is this just a terrible bug from the combination of my footage, effects, and sequence settings? The footage is AVC MPEG-4 Quicktime from a 5D MarkII and some other Canon. Both 24p YUV 4:2:0.
