In Properties you have Pixel Format with three choices: 8 bit, 32 bit video, 32bit Full. The video in the preview sceen looks MUCH different in 32bit Full. So what is the difference in editing or in the final rendering ?
@Gerrie - Hi there!
This from p45 of our Users Manual:
”Choose a setting from the drop-down list to indicate whether you want to perform video processing (compositing, scaling, previewing, rendering, and most video plug-ins) using 8-bit or 32-bit, floating- point arithmetic. l 8-bit:Performsvideoprocessingusing8-bitarithmeticandin the video (studio RGB, or 16-235) color space. l 32-bitfloatingpoint(videolevels):Performsvideoprocessing using 32-bit arithmetic and in the video color space. l 32-bitfloatingpoint(fullrange):Performsvideoprocessing using 32-bit arithmetic and in the full-range color space. The 32-bit floating point settings allow greater precision for processing video, but require significantly more processing power than working with 8-bit video. Tips: l 32-bitfloatingpoint(videolevels)isrecommendedwhen working with 10-bit YUV input/output or when using xvYCC/x.v.Color media. l Whenusing8-bitinput/output,the32-bitfloatingpoint(video levels) setting can prevent banding from compositing that contains fades, feathered edges, or gradients. l Videoplug-insandmediageneratorsthatsupportfloating-point processing are included in the 32-bit floating point folder in the Transitions, Video FX, Media Generators, Compositors, and Plug-In Manager windows. l Ifyou'recreatinga32-bitproject,youcanincreaseperformance during editing and playback by using the 8-bit setting during editing and switching to 32-bit floating point (video levels) before rendering.”
HTH?
?????????????????????
Use 8 bit processing for 8 bit source, which is 99% of all video.
Use 32-bit processing when you will be grading 10 bit source, otherwise you can create a lot of extra time and mess up colorspace handling, as you have already seen.

^Ditto. You are wasting a ton of processing power if you aren't grading video above 8 bit, slowing your system down for no real gain in the end if you are working with 8 bit video, which as musicvid points out, is what the majority of cameras shoot.
This marketing blurb, which was never substantiated, appeared in an early SCS pre-release packet in 2007, and somehow made its way into the Sony manual, and eventually the new one.
Dozens of hours spent trying to confirm this premise, in either a technical or practical sense, failed at the outset,using an empirical testing model. In fact, it revealed a significant amount of shadow (dither) noise, which more than rules out any theoretical gains from employing 10 bit processing of 8 bit I/O.
Having ruled out such a possibility in one set of controlled tests, I would disregard this anecdotal theory entirely until proven otherwise, and continue following the advice of @fr0sty.
