  • GV HQ File quality

    i n eed to send someone some files for editing overseas. im sending thru dropbox and have plenty of space to send.
    when im converting these files off the timeline, with my choices being HQ fine, HQX fine or super fine, or GV Lossless. Ive notice the files go from 3.6gb for lossless, 3.1 for HQX Super and 1gb for HQ Fine. GV lossless seem to be my best bet to have a duplicate file identical in quality of the original. Just wanted to confirm this would be the ideal way to go over the other 2. the clip was 1:39 minutes.

    I would export Prores 4:2:2 as this is 10bit in case your project is 10bit

    Lossless is 8bit and can only be edited by someone with EDIUS or the codec pack installed

    If he didn't have Edius, I would agree with Anton, but since he has Edius, ProRes or HQX are the best choices to preserve the 10bit colour, but for the sake of maximum quality, I would lean toward HQX, but ramp the quality way up by using a custom settings, reducing the Q (quantization) and increasing the max size in the settings. Theoretically this could be substantially better quality than ProRes if the video need to use the extra bandwidth headroom (almost twice as high a cap as ProRes HQ) you are allowing it to access and less aggressive compression by using the reduced Q setting.

    You will see the option to enable the custom settings once you click past the first preset selection window and get to the one where you name your file. The preset qualities, custom option, Q slider and max file size slider are there.

          As I said above, reduce the Q and increase the Max File Size. If you jump between the different presets, you can see the direction the sliders move to increase or decrease. Maximum quality is sliders to the extreme settings.
