Cinema Tools loses mbps when conform to lower frame rate?
When I export a QT pro res HQ movie out of MOTION 4, with the same settings as the sequence (Pro res HQ 422, 59,96 fps 1280x720p), it renders out a good, same 221mbps file, but when I then take that file into Cinema Tools and conform it to 23.98fps, the file is now 88mbps? Why and how, and did losing 140mbps somehow lose also color correction and other quality capabilities?
Why does CT lose many mbps when conforming to lower frame rate?
Thanks

You have eliminated more than half the frames in the clip. That’s why the data rate is lower.
There were 59.94 frames in one second before. Now there are only 23.98 frames in one second.

Thanks – so I haven’t yet had time to color correct anything – but will that 88mbps version somehow have less to work with when color grading or is it all intact because it’s still Pro Res 422 HQ? Did the half frame rate simply reduce the mbps or are there other detriments now?
Thanks

Conforming is just playing the same movie at a different speed.
The file doesn’t changes size.Conformed or not, you are correcting the very same picture. The same number of frames with the same number of pixels..
The data rate changes nothing for Color.
