HD footage- Transcode or export a usable QT

I have tried to find an answer to this and nothing seems to work.

I have P2 footage. It was shoot as 720PN24.

I had to edit in the 1080p24 Timeline so I could view on external monitor.
(720p timeline in Avid does not let you downrez format to SD)

My project is finished.

Please explain how I transcode or export QT for import into Encore or DVDSP.

I have been trying everything and I always end up with an error somewhere along the way. For example;
I Transcoded to MXF 1:1. Then export a Same as Source QT file. I am able to import the video into Encore, but the audio stops halfway and gives me an error window.

I also tried exporting a Same as Source HD QT into Sorenson and I get a "progressive field frames are wrong" message.

Can someone please give me a step by step, settings, etc guideline to doing this?
The Avid website has no such info. I'm at my wits end.


Thank you so much.

I'm guessing that you're working with something like MC Soft/Adrenaline, as Xpress doesn't let you bring 720p media into a 1080p project (I'm working with Xpress, so take this with a grain of salt...)

You shouldn't have to transcode anything--I don't think you do anyway. You should be able to just spit out a QT reference file, bring that into your encoding app, and render the MPEG-2 file from there. It'll take awhile to squeeze it down, but it should work. There's information at 24p.com about creating a 24p DVD from said media... it's http://www.24p.com/24pMPEG.htm

The only other thing I can think of is that you may somehow need to decompose your 1080 project and relink it in a 720 project. Perhaps there is some issue arising between what the frame size IS and what it's expected to be. Grasping at straws here... I don't have much information on that, as I've never worked in that capacity. At any rate, that could explain why you get the "progressive fields/wrong" message in Sorenson... because I think a 1080 project in Avid is actually a 1080/60i project, even when you're working with 24p media. Could be wrong there, though...

Sorry... more confusion than answers!
 
Thanks. that helped. I was able to get it into squeeze and drag the resulting files into Encore.
Unfortunately the resulting dvd doesn't look as good as it did when played down from the Avid. Wide shots look soft. Color bleeds.
Bad compression perhaps.
I'll have to keep tweaking the settings.
 
Depending on what project you exported from, you may indeed have some shots that look soft. Again, I'm guessing here, but if you used 720 media in a 1080 project, it's already been stretched to fit the frame. Then, going to an SD DVD with MPEG-2 is going to result in not the best compression. I created an SD DVD the other day from a 720p project, and I've got to say, I was extremely impressed with how good it looked. I'd say, do a test from your non-uprezzed 720p media, and see how that looks. That'll tell you whether it's in the up-rez to 1080, or somewhere in the MPEG-2 compression.
