When i send my file from smoke to final cut, the luminance and colors of the file change...The whites beyond the 100 of waveform in final cut. I dont understand weel how i do this interchange between programs and i would like some literature about this. What Scale does final cut work: IRE, RGB, YUV...and what Scale does smoke work?
Smoke works in RGB, final cut works in either YUV or RGB, if you change your sequence settings in final cut to always render in RGB this sohuld fix the issue (i know this has worked for me going back and forth from ae to final cut)
there is also a setting in quicktime regarding gamma in Preferences called enable final cut studio color compatibility, try enabling this checkbox
