In Vegas Pro 18 there is a new pixel format project setting which is "8 bit (full level)" and which is the default setting now.
When 8 bit full level is selected Vegas Pro tries to conform all input media luma levels to computer RGB levels to provide proper levels for the internal preview.
- Vegas Pro checks if the input video file is RGB or Y'CbCr. If it is RGB no level transformation will be applied (because RGB data is meant to be computer level).
- If the input video file is Y'CbCr Vegas Pro looks for the color range meta data. If there is no such meta data, Vegas Pro assumes the color range is limited and applies a studio levels to computer levels transformation (because Y'CbCr video usually is meant to be studio levels).
- If the Y'CbCr video meta data for the color range is "limited" Vegas Pro also applies a studio levels to computer levels transformation.
- If the Y'CbCr video meta data for the color range is "full" no level transformation will be applied.
- If the input media is a photo or grafic file format no level transformation will be applied.
- If there's the need to switch the input level you can do this by opening the file property window(s) of the selected file(s) and manually set the color range option (this works both from the timeline and the Project Media window).
- If you render a project with the project's pixel format set to 8 bit full level, by default Vegas Pro will apply a computer level to studio level transformation for the output file and automatically set the output file's color range meta data to "limited".
- In the render window's project tab you can switch this color range output option to "full", thus no computer level to studio level transformation will be applied and the output file's color range meta data will be set to "full".
Note that not all video formats support such a color range meta data. In this case the color range usually is used as "limited" for all Y'CbCr media.
