  • 10bit to 8bit when black and white?

    I have a lot of 16mm and 35mm film scans in the following file format ProRes 422 HQ 10-bit

    Does it really matter if the content is black and white if I convert it to 8-bit during restoration, am I losing any information/quality in the conversion? From what I've researched online it sounds like it only matters if it's color.

    try this little test

    start an 8bit project and add a color matte with two shades of gray (no color) in a diagonal way, you will see horrible banding
    now switch project to 10bit and the banding is gone

      the advantage with 10bit is that you can have many more shades of any colour or in your case, shades of white and black. you might be lucky and can use 8bit as you might not have any banding, but I would recommend 10bit. you never know what you might need to do to the footage moving forward, and if you need to grade something, better to have 10bit than 8bit in most cases.
