output setting for Premeire
I need to out put the green screen footage that i shot. I need the best compression (or no compression settings) that work best with keying out the green in after effects. right now when i bring in an AVI i get Raster lines and just not a smooth edge to my reletively unmoving subject.
I have played around a bit with setting, but am not satisfied. I am not sure if i should interlace or deinterlace. AVI or WMV? (is there a tutorial on this?)
Anyone out there who has had success with this you input would be great.
i am in CS2.

If this is interlaced, well, that’s your call. I’ve seen many people here at the cow recommending a deinterlace. While that’s great for compositing, you’ll also get a big hit on the resulting resolution.
I now almost exclusively work in progressive, but I’ve never deinterlaced unless it was going to the web.
I bring the native footage to AE and work in a square pixel composition. I do my Keying with Primatte which I can’t recommend enough. I also do all my backgrounds in AE, since that allows me to add a light wrap and color matching to sell the shots. I then export with Quicktime Animation (no need for alpha channel).
That’s about it.
Cheers,

What’s the original footage? I’d stay with that format, unless it requires re-compression. For robustness, export file sequences; PNG will save some space and is uncompressed. If you’re using interlaced footage, keep it interlaced.
Anyone recommending de-interlacing for keying or compositing probably means: convert fields to frames (i.e., 30 FPS to 60 FPS), key, re-interlace (60 FPS back to 30 FPS). Not really necessary with contemporary software.
That said, I haven’t used AE in several years (Combustion is my compositing app of choice), so your results may vary.-jeff

Jeff,
Just a quick comment on the “Progressive Scan” method you mentionned. You will indeed keep the full resolution, but you will also get a “jumping” effect on static images and logos, so I gave up on that method as well.
Cheers,
Vince

Vince– I’ve never bothered with the method myself. I just let the software deal with fields. ‘Course, if you’re using steam-powered software instead of that new-fangled electric stuff, you might need the workaround…

Is there a reason you can’t import the original clip into After Effects?
Your clip quality is only as good as its original digitized format. If it’s DV or HDV you won’t get a better quality by exporting it to uncompressed. It will just be a larger file with the same pixel info.
Key it with Keylight. check the adobe video tutorials on how to use it.

Any reason not to key it in Premiere Pro? If the key is decent you can get great results with it(CS3 anyway). Otherwise – keep it in the native format as long as possible.
