HMC150 - Cineform - AE CS4 for green screen?
on Feb 13, 2010 at 12:15:59 am

Hey Everyone,

I just finished a week of shooting interviews in front of a green screen using my HMC150. Now the question becomes, what is the best way to integrate these green screen shots into my already large project?

I should say this is my first HD project so I'm probably unfamiliar with some of the tricks that would make this much easier on me, so please point them out!

I have probably 10 hours of green screen interview footage, and will end up with 10 hours of B-roll footage, covering classrooms, labs, etc, as this is a promo for a local college. So around 20 hours total footage. The college has many departments that each need a video, so this is why there is so much footage.

We will be doing a bit of color correction, and perhaps some added effects on the project, so I decided I will probably buy Cineform Neo as my master codec. That and after some tests it seems Cineform keys much better than AVCHD in AE CS4.


This is however my first time using PPro and AE CS4. Can someone suggest some good work flow options? I'm under the assumption that it will go something like this:

1. Import footage onto PC
(Vista 64bit, I7 720 processor, 12gigs ram, ATI radeon HD 4850, 2 TB storage)
2. Batch convert all AVCHD footage to Cineform
3. Import all Cineform footage into PPro CS4
4. Edit down to a final cut
5. Dynamic link PPro sequence to AE CS4, key out green screen w/ primatte, add in any additional effects or text.
6. Final export to DVD and web from PPro or AE?

The College wants the finished products for DVD and for their web pages.

I suppose I could try to keep everything in PPro CS4 if they make a good keying tool for it, but I've heard using primatte in AE is best.

I'm sure I'm overlooking a lot here or I'm mistaken about how I should go about transferring footage from PPro to AE, so let me know what recommendations you would make. And if you need any more info on my project or setup to make a recommendation please let me know. Thanks!

I'd suggest asking this over on the Adobe forum instead of here- more experts to help you. But that workflow sounds ok to me. Though if you're not keying everything you might hold off on converting all the footage to Cineform and just do it on the final edit instead. Save a lot of time and disk space.

How would this work? I would:
- bring everything into PPro as AVCHD off the camera,
- then edit it all down to the clips I think I'll be using,
- then export that from PPro as cineform.
- Import that into AE, do all the effects, color correction, and keying
- then export from AE to mpeg2 for dvd?

I'm not 100% familiar with the Premiere workflow but generally speaking most editors have a media manager type function where they will automatically take any timeline and recreate it with handles in whatever format you choose.

In this case you'd cut a native AVCHD edit in Premiere then have the program export to another Premiere project but everything will be recompressed to Cineform. But the recompressed part will be only the portions you used in the edit- typically plus a few seconds handles to give you some wiggle room in the final edit. I'd ask on an Adobe forum exactly the steps to make this happen. But that would be a more efficient workflow for you.
