There might be some issues with an RGB still in a YUV sequence. Final Cut treats RGB stills as if they had a gamma of 1.8 by default (although you can change this in the Item Properties). It's possible that there is an inconsistency here, although I'm not aware of any specific issues. If you want, you can send me your project and linear ramp image, and I can take a look. I may be going mad, but it appears that the image data I get in an FxPlug plug-in when jumping around the timeline in FCP is different to when I render a sequence - it appears that it has been through a slight gamma correction (although nothing as extreme as sRGB). To verify this I dropped a linear ramp image into my timeline - zero on the left and full white on the right. Plotting the intensity from left to right inside the plug-in yielded a curve when jumping around the timeline, but a straight line (as expected) when rendering the sequence. Is this expected behaviour - maybe something to do with FCP correcting for the display? If so, is there a way to know if the data you're getting has been corrected, or whether you're in a render?
