Color changes in preview

Question

Hello, I'm so tired trying to figure out the reason of a problem in Premiere Pro (my version is 6.0.4). I'm very frustrated just because I've spent too much time trying to solve the problem which is so ridiculous! What I'm doing is just trying to color corect my footage with the help of Color Finesse plugin. The problem is that I can see different results in full screen Color Finesse preview and PP windows preview. Sure you could kick me off this forum saying that it's not Premiere Pro but 3-d party plugin problem but I want to tell you that it's not!
The point is that I can see the right result of the color correction in Premiere Pro when I'm scrolling the preview unless I mouse up to stop the timeline cursor being dragged. Once I just mouse up the image in preview changes! I even set up the similar options of resolution for playback and pause in preview but I still can see the same issue. I also tried to change the sequence options of preview rendering (max bit depth, max rendering quality) but all in vain. I surely get this result when exporting - it seems that PP use in this situation the same rendering engine as what is shown in preview when the cursor stops.
But what really confuses me that in dragging timeline cursor mode I can see the proper colors that I made with Color Finesse! Isn't it an issue?! Haven't anybody noticed anything similar? The image in my case seems to be more red and whites are cut. I thought that there is might be some problems with color spaces but I just don't know what to do in Premiere! I tried to color correct my footage in After Effects with the same Color Finesse settings and then export it  - everything is ok with colors! But not in premiere! By the way in both cases of exporting (premiere, after effects) I can see that the result image is in YUV color space with chroma subsampling 4:2:0, 8 bits, progressive though I choose RGB in After Effects when exporting (I can see it in Media Player Classic's properties of the footage).
Please, can anyone help me with this issue or is it really an Adobe Premiere bug?
I thought that there are some problems with color spaces and tried to watch YC waveform. But I guess that my original footage was even worse in it though I can not see any issues or color cutting with my original footage in premiere pro window. Color finesse window show another results. What's happening?...

Answer 1

Thank you, Bob, for answering. And I would also would like to thank you for creating such a convenient instrument for After Effects (cause you see - I seem to can not use it under premiere pro).
I guessed that in dragging mode PPro tried to optimise rendering in different ways clipping it from all the sides etc. But the problem is that all is vice versa: I do like the result in dragging mode and it's the same as in full Color Cinesse instrument and I can see clipping in stop cursor preview mode. Unfortunately there is no any difference on Ppro YCwaveform in this two modes (dragging, stop cursor) so I have to load images from footages (from Composite Video view).
That's why It does not help that the result I see in PPro when not dragging is what will render to my final output (maybe I'm wrong, maybe highlights are not cut but just more reddish...but I can feel more difference in video - the first one looks much better).
Do I correctly understand that dragging mode differs from stopping not just in that 8-bit image is handed instead of 32-bit but also that the first one is RGB but the second one is YUV (there are no YUV modes in Color Finesse full interface in some reason)? So is it possible that clipping happens with 32-bit YUV image? We could test your plugin by feeding it my original video footage (you should test it in PPro) - if you wish - and you could see - why there is difference (I understand that it may take some time so I seem to not wait to the results and find another way of color correcting though I very much like Color Finesse).
So - I'm sorry. In this case the problem seems to be exactly in Color Finesse? But anyway I don't understand why not implement Color Management in PPro such as it's done in After Effects or maybe even better by having several options. I think that sometimes you'd better have several options instead having no ability to do something.
P.S. Bob, I also have a suggestion for your plugin - it's kind of UI improvement. It's a good idea to have the ability to reset each option (each slider) by just double clicking on it's name just as it's done in Lightroom.
