Smart, mild compression that supports manageable post operations with minimal quality loss can be a excellent alternative to the "uncompressed at all costs" approach. Mezzanine codecs at appropriate data rates rock.

    IMO, the hellscape is over-compression - particularly with a fixed maximum bitrate regardless of the material. Sadly, far too many content creators don't really understand how codecs work.

    The power of BRAW... it's an all in one codec and the user can choose how it works(compression ratio fixed/quality, Mezzanine and even delivery).

    Yeah. here you go:

    1) Click on sample Images




    2) Click on the "Title" of the name of the clip





    3) Select which DNG frame you want to Download




    4) "Right-Click" on the DNG image and choose "Download" from the menu
