after effects to avid dv widescreen
Hi all,
I am working with DV widescreen footage in aefx. Created comp using preset DV widescreen 720×480 anamorphic. Rendered out to avid meridian codec and sne to client. They are saying that the files are jittery. I bring same files into Premier on my end and they work fine. The final output from client’s avid is to DVD SD letterbox. I also created a 16:9 DVD here and it looks fine. Could the client be importing the files wrong? I am not that familiar with Avid, but is it like Premier where you create a project with settings specific to the job? So if client has Avid set to 720×486, and brings in my file with is scale it vertically and mess up the fields… hence making it jittery?
Thanks!

Spot on. You set-up the wrong size file.
Make your AE comp 720×486 because Avid uses D1, not DV resolution.
The jittery result they see are stuffed up fields. Also make sure you render lower field first. -
Have your guys check the Maintain Non-Square import option. It should keep Avid from scaling the image to fit 720×486 and will just add 6 black pixels to fill that space. If that doesn’t work, rerender like _____RB_____ suggested.

To complicate matters, NTSC DVD-video is 720×480. During the encode to Mpeg2 those extra 6 pixels will need to be trimmed off. Usually 2 pixels from the top, 4 from the bottom (even numbers to keep the field order correct).
Also you mentioned that they are letterboxing, which means that they are either masking the top and bottom of the frame off,in the case of 4×3 footage they want to look like widescreen, or in the case of anamorphic widescreen source, they are scaling widescren video to fit proportionally with in the 4×3 frame, losing vertical resolution in the process.Erik

Thanks all! My main question is what resolution do all the Avids edit in? Xpress pro is DV right? Media Composer can do both DV and NTSC right? Is there a chart somewhere that lists all the import export settings for all Avids? My client does his offline on Xpress Pro, sends me edited greenscreen shots, where I treat them and send them to post house that works on Media Composer…

I don’t think it has changed since then.

As far as I know, Avid Xpress Pro/HD/MC DV25 capture and edit is 720×480. Analog captured 1:1 is 720×486.
