Mike,
Thanks so much for devoting so much time to help me…I wanted to fill you in on what happened with the project.
Well, it is finished, and worked well…the client ended up wanting some significant animation (moving masks with varying transparencies and more). So it was a good thing I worked in AFX!
Bottom line though, after my first significant 16:9 project. I’m still not completely clear exactly what happened with the clips.
I exported from Media Composer as Same as source. It gave me the option of choosing the Pixel Aspect Ratio; Square / 4:3 non-square / 16:9 non-square. — I chose the 16:9 non-square.
When I imported into Xpress…there weren’t any settings to work in 720 x 486 (as opposed to 480). So I did the standard 601 non-square import setting at 1:1.
I then did my editing, and exported a QT Ref. The settings in that allowed the Pixel Dimensions as: Native Dimensions / 4:3 Square / 16:9 square.
I chose native and took them into AFX. The clip info in AFX said they were 720 x 486 (.9 PAR) When dropped into a widescreen comp (720 x 486 1.2 PAR) I had to scale them up 133% horizontally.
I did some tests and if I choose the 16:9 square from the output for QT ref, they are 864 x 486 at 1.0 PAR.
Also, one question on the rendering. I had to make them 720 x 486 so the Meriden codec would accept them. I had 2 options, drop them into a 720 x 486 comp and scale down. Or Scale in the rendering settings. Is there a preffered method? Is one better than the other?
All in all, I learned that:
Non-square pixels suck! — I was working with square pixel images in a non-square comp…so I had to disproportionately (sp?) scale them horizontally to match the 1.2 PAR of my comp! And if I wanted to do any rotation on them, they would go out of perspective.
My final decision on the best workflow in this situation is to use square pixels…either scale up the video clips or export them at square pixels. So the pictures that I used a ton of and animated pretty heavily were in their native PAR.
Just wanted to give you the low-down on what happened with me…if you have any advice or ideas, I’d love to hear them!
