    Sequence Settings Video Previews and GPU?

    ArtifaktAstrix Community Member

      Dear PrP CC Users,

       

      I wanted to get some information partaining to sequence settings.

       

      In the bottom box of Sequence Settings: Video Previews. There are three un/tick boxes:

       

      Maximum Bit Depth

      Maximum Render Quality

      Composite In Linear Color (requires GPU acceleration or max render quality)

       

      Normally I tick all of them. I have a Windforce GTX 770 4GB CUDA mercury engine enabled. I have also set to Optimise rendering for: Performance.

       

      My questions are as follows.

      -Do these selections effect the final output of a timeline for delivery or is it merely for during regular playback and preview rendering?

      -Also, when I export using Media Encoder through dynamic link, is it bad to Use Previews for a faster export, often I export to ProRes4444 for Grading, I heard that Preview files will always differ as its created by the GPU and can slightly change the colours dependent on the GPU you have, thus is it better to export and allow it to re-render using the CPU in Media Encoder (I always set maximum bit depth and quality)?

      -Lastly, in the export process, when I select Maximum Bit Depth, there are options of the bit depth value (32, 48, 64) does this become redundant since I checked maximum bit depth?

       

      Thank you.
