I created a graphic exactly with those dimensions, and overlaid it on the video I have ( which is original size of 1280x720)
( the graphic I overlaid is a very simple picture frame )
When I overlay the graphic over the video, it is MUCH smaller than the video in Premiere. ( I understand this is normal because my original video is larger )
Question: What should I do ? I want the simple border/picture frame to be the best quality possible in the output video. So what do you suggest ? ... Do you re-create the graphic so it matches the original video ? or do you size down the video so it fits into the frame ? - I tried this, but now I have a large black area on my work window in Premiere, because the frame is so small in relation to the video. I'm not sure how to proceed at this point.
I would appreciate any of your responses / suggestions.
Assuming you are working in a custom (desktop) 1280x720 project, I would suggest to use a graphic that has the same dimensions as the video and to do the shrinking to 432x280 at the end (in the Adobe Media Encoder export).
