1. Well for the offline edit, i've used mr Shaw's plugin, but do i have to remove them if i want to submit it to the online editor for color grading etc to maintain the Log C dynamic range.....
You should be sending the colourist an EDL or XML and the original LogC media, NOT
a QuickTime export from FCP, so plugins applied in FCP are not really relevant.
But if for some reason it becomes necessary to export media from FCP to sent to the colourist, then it is absolutely vital
you remove my plugin before doing so. But I would strongly recommend against that approach. The colourist will be able to achieve the best results if they have the original media to work from, not something that has been processed through FCP.
if i remove Shaw's LUT plugin from my other clips, will there be any problem to grade and match the colors? or its better for me to leave the plugin in the clips? but this will also result the clips to not preserve the dynamics( maybe the blacks crushed and whites are burned)
See my first answer, but worth also noting you should also send the colourist a copy of the offline as a reference. If your colourist is not able to match what my plugin did in the offline, you should be concerned about their abilities as a colourist!
3. As u can see in the previous posts, i'm going to crop this movie to a 2:35 ratio, and there are keyframes involved as the frame moves. Is it possible for me, to give the Online editor 1 clip of each film reel (each film reel are rendered to 1 QT file), or is it better to give him an EDL? but i'm not sure if i give him an EDL, it will follow my keyframed 2:35 ratio....
filter will not come across in an EDL, and would not be understood by Baselight in an XML. If you had simply placed a mask on another layer in FCP and used ordinary transforms to re-rack the images that would come across to Baselight via XML for example.
You have two options really:
1. Let the colourist re-build your racking manually in the grading system, using your offline as a reference.
2. If you are round tripping and finishing in FCP (this may or may not be suitable depending on your final deliverable requirements) you can grade the full image and then the widescreen
filter will be reapplied when you round-trip back to FCP, although you will need to remove my LUT plugin at this point.
