    Saying uncompressed rgb 4:4:4:4, is akin to saying, the project was shot on electronic camera:-) You need more info, than what you have provided. For example, it can be AJA or BM QT codec...

    The project is a super 16mm film project, they are staying digital after we digitize the HDCAM SR tape to uncompressed rgb 4444 it could be a quicktime or aja codec what would you recommend for an online edit codec from super 16, we cant go back to film so it has to be digital.

    It makes no difference what your originating format is for the purpose of this discussion. Your HDCAM SR will need to be digitized, so depending on the card used QT codec will be chosen, unless something like DPX is used. Personally I would use DPX over QT. Anyway, you want to know, if Scratch can use uncompressed 4444 codec? The answer depends on what codecs you have installed on your computer and codec used for digitizing. Basically, if Scratch computer can play your QT file, then Scratch will be able to work with it. Get the file and try to play it. If it is an AJA or BM codec, then it is very easy to install, even if you don't have those codecs installed already. If it is DPX, then no codec is needed.

    In this case I'd use dpx.

    In that case, there is no "4:4:4:4" because DPX is not a video format, and doesn't carry an embedded alpha channel.
