Has anyone got experiance in using this? if so how much RAM do you have? at what level does it start to become unstable?
I have and edit computer at work with 8GB RAM and also one at home with 4GB, if i dont have to upgrade the home one it would be usefull, if the 8GB is'nt enough then maybe i'll have to give it a miss, it would be usefull though as i have a big PP project with lots of clips in them that need AE work doing on them, as i understand it Dynamic link will allow me to open them from the PP timeline in AE then it will import those changes back into the clip on the timeline. Or have i got it wrong??
This is worth a read:
4GB won't get you started. 8GB might be OK, but I would say that, in my experience, 12GB RAM is the minimum for working happily with CS5.5 and Dynamic Link. I have two pretty identical i7 machines, one with 12 and one with 24GB and the 24GB one is an order of magnitude faster in AE, let alone in Dynamically Linked projects.
Your understanding of Dynamic link is fairly accurate. You right click on the clip on a Premiere Pro timeline that you want to work on in After Effects and choose "replace with After Effects Composition". AE then opens up and you do the work. Anything you do in AE is instantly reflected on your PPRo timeline. You don't need to bring it back into Premiere Pro.
Thanks for that mark, i guess i'll have to test it at work on the 8GB machine then if that works well enough i may upgrade my home PC. As far as i can see the MoBo's i can afford only support up to 8GB, trying to use all the bits from my old PC minus the MoBo, Ram and case (It's an Asus Pundit barebone system)
What I would suggest, to maximise your resources, and if you have enough hard discs, would be to arrange your OS and Premiere Resources thus:
C:/ = system drive
D:/ or fastest other drive = Project File, video and audio assets
E:/ next fastest drive = Premiere Pro/AE Scratch Disk (set this in preferences) plus Windows Page File (you'll be using this a lot with only 4/8GB RAM) or even better
F:/ Windows Page File. Make sure your page file is set to a fixed amount of twice your installed RAM.
Thats pretty much what i have as a set up now.
Tested some keying using Dynamic link from within PP in AE, seemed ok, may not have been rocket speed but it did'nt crash which was my maine worry.
Now i just have to get some keying experiance under my belt as my new project is all green screen. First results were'nt that great and the model looks like they were shot on VHS (it was an EX3 in fact) need to play around with the black and white levels in the keylight effect.
Glad you're not crashing!
Have you tried playing with the Ultra Key in Premiere? It's pretty good, and may save you all that Dynamic Linking.
Some tutorials for Keylight if Ultra Key isn't cutting it:
Hmm, thinking that might be a better option, the whole project will have about 200 green screen clips, all shot in a studio, so in theory i should be able to apply the the matt and key to one (the camera was'nt moved) and then just paste atributes on the rest. A lot quicker than doing each clip + i can probably get away with leaveing my home PC at 4GB as it should do the job if a little slowly!!

I don't wish to be a damp squib here Dominic but that theory isn't going to work if your foreground subject matter changes. You didn't say whether these clips are of people against green - bald, brunette, blonde etc. or maybe 200 different shiny cars. If you have 200 different subjects then I'm afraid they will all need to be checked and tweaked individually as they will each have possible tints/reflections from the green screen.
200 isn't such a big number:)
Thanks Dugi, i'm pretty lucky as of the 200+ shot only about 10 are differant. All were shot of the same person/postion/lighting etc. If i go a bit wider on the garbage Matte than i normal then that will cover me for any slight movment, i can then go back and tweak any that need it.
