  • imported graphics files: quality degraded on mixdown

    Posted by Kathryn Cates on October 6, 2014 at 3:30 pm

    I have a DNX36 project into which I have imported titles in .TIF form (also imported at DNX36). Titles superimposed on the footage within the timeline looks great, but when I do a video mixdown of all tracks (to DNX36), there is a slight but perceptible quality loss on the titles only. The tiniest bit blocky within the text. (Alpha remains fine.)

    Any ideas? Should I import the TIFs at higher-than-DNX36 quality? Why would mixing something down to its original resolution result in quality loss? I’m stumped.

    Many thanks!

    DNx36 is an offline (low res) codec…quality really isn’t the strong suit. If you want better quality, wait until you online at a higher DNxHD setting.

    Right, we’re still in offline so we are of course not working at optimal quality – but I’m confused as to why the quality would *change* just by doing a mixdown to the same resolution. More intellectual curiosity than anything.
