Degrading quality?
How does PPRO handle the video material internally?
What happens if I create a DV-PAL project 720×576, lower-field first.
Then I import from harddisc a uncompressed 4:4:2 progressive 10-bit, footage.
I put it on my timeline.
I export my timeline to disc, with the exact same settings as the imported footage (uncompressed 4:4:2 progressive 10-bit).Will the new saved footage, be degenerated?
Or does PPRO leave the quality intact?Do I make sence here??

It is compression that degenerates and exporting uncompressed should not, although if the original was interlaced and the export is not, Premiere is going to throw out half your horizontal resolution and replace with duplicates of what is left.

I edited once progressive image sequences captured with a DSLR, in a Pal, lower field first project.
I applied opacity and duration changes to some of the clips, and in some slo-mo’s I got interlacing problems even though my source AND export settings were progressive.
When I changed my project settings to a custom Pal NO FIELDS project, all problems disappeared.
I am assuming premiere applies some effects according to the project settings and NOT source properties, so take that into account.
