    Background vs Foreground render

    Just did a test with rendering Arri Alexa LogC footage from AMA into DNxHR LB footage.

    AMA Linked clip

    Looks correct, matches other cameras from same shoot.

    Colour Space: YCbCr Arri ALEXA LogC [video levels]

    Color Tranformation: Levels scaling (video levels)

     

    Transcode settings:

    Maintain source frame rate. 

    Apply colour transformations box is checked

     

    Background render 

    resulting clip appears as flat as if no LUT or Color transform is applied. (milky, washed out)

    Colour Space: YCbCr REC709 [video levels]

    Color Tranformation: - blank-

     

    Foreground render 

    resulting clip appears the same as AMA linked clip. (Proper color, matches other cameras) 

    Colour Space: YCbCr REC709 [video levels]

    Color Tranformation: - blank-

     

    So the same clip transcoded with exactly the same settings produces different results with background or foreground rendering.
