Would anyone happen to know the difference?
If your footage is interlaced just drop it in an interlaced sequence.
On export you set the export settings to progressive.
Always deinterlace in the field options is used basicly for stills (or freeze frame) in a interlaced enviroment
Or when a clip has a speed of < 100%.
Reverse Field Domanance is something left over from the SD period were avi's were lower field.
One can use this also when a clip has a speed of >100% or is played reversed, but I think this also applies only to SD footage with lower field.
I would only use interprete footage when I know Premiere is interpreting the fields wrong.
Thank you very much for your reply and clarifications on the different uses for each function. However I should have been a little more specific, my video is coming from various sources and I'll be mixing interlaced with progressive video, using many quick cuts and crossfades. Do you think using Always Deinterlace for those clips will be sufficient, or should I spend the time converting my footage to progressive and simply using a progressive sequence?
Any advice is greatly appreciated!
Assume the output will be progressieve so just drop everything in a progressive timeline and see how it goes.
