My project settings say 1920x1080, 25fps, 8 Bit. My XAVC-S files are all 8-Bit (Sony A6300)
My Video Preview Window says project is 1920x1080x32. And Full Preview is 1920x1080x32. 'Display' says its 1920x1080x32.
I would like to preserve some computing power during the edit process, using 8 Bit, until the final stage. What can I trust here?? In my mind, the difference could be as much as 4x the data rate-?
32 is 8 bit. 8 bits per component. With RGB, that is 8 bits for each primary color, another 8 bits for alpha (transparency) effects. 8 bits x 4 components = 32bit.
Change pixel format (File>Properties>Pixel format: from 8-bit to 32-bit) will make the project note goes to : 1920x1080x128
(32*4=128)
Yeah, if you select 32bit floating point, not only will your gamma levels shift dramatically, causing you to have to do level adjustments and such to get it back where you need it to be, you also have to do your color and brightness adjustments differently if I remember right, and not all vegas plugins support 32 bit, so your favorite effect might ruin your color or not work at all. I would only use that if you are trying to color grade within vegas, especially if you are starting with 10bit per component video (or higher).
If I remember right, it also does not have anything to do with how vegas interprets bits per pixel, but rather the accuracy of the floating point math it uses to process the video. I'm sure there are others here that could provide more detail there.
Aaah, very insightful, thanks Vegasians, I've learned something here, appreciated!
32bit (Video level) is a 'friendlier workflow to do' rather than 32bit (Full Range).
In Video Level, I don't have a gamma issue.
