Premier Pro Workflow question

Question

Hi,
I am wondering, from an industry standard point of view, what the reccomended workflow would be for the following situation (I know that each project brings its own special requirements, but I was hoping that some of you on the forum have worked with this type of project before, and can give some advice)
We are producing several, roughly 20 minute episodes of a childrens show. The episode has several scenes, and each scene is comprised of several shots. Our characters are hand operated miniature figures, and they are filmed against either a blue/green screen, or in miniature scale sets. The footage is first brought into Premier, where rough keying and compositing is done, to achieve each rough shot. These are then edited into their respective scenes. Once the rough editing is done, the project is handed over to Afer Effects, where the footage is replaced with the originals (As low res proxies are used in the edits), proper keying and compositing is done, and effects are added. This is then rendered as a DI, imported back into Premier as a video layer and then rendered out in the final delivery codec.
My question is as follows:
Is it better to create one project, with multiple sequences, one for each scene and then a sequence for the episode (Master sequence) - or is it more advisable to create several seperate premier projects, one per scene and then import these into a new master Episode project? I guess it might be a matter of "What you prefer", but I was wondering if there is a suggested industry standard as to how this is normally approached.
Thank you for any advice,
Pierre Devereux

Hi Guys,
Thank you all for your input - it really is helpfull.
On the two topics my question created:
One VS Two Projects - We have decided to go for the approach of several projects per episode, each containing its own sequence of several shots. These will be dynamically linked back to AE for the duration of the work on that scene to make back and forth work better. Each project will be imported in a main episode project, and final edits will be done there. This will also help us, beacuse as mentioned, we have several people working on a project at the same time - we will be able to work easier accross mulitple PC's this way.
DI VS Dynamic link, or direct AE export - We do daily renders of our AE projects (there are a few reasons for this, one being the fact that our hardware is not up to scratch, so working woth 4K layers just doesnt work on the editing system) into proxy and intermediate codecs as Fuzzy stated. As a result, we have these files, and placing them into the premier timeline allows us to do any last minute edits quickly (transitions, small cuts etc) and then a much quicker final render to delivery codec. There are also other tracks added before the final render, sound layers being one fo them.
I am aware that there are always several ways to complete any project, and workflows are fluid things, able to change as needed, but for now, this seems to be the one that suits us best.
Steven,
Thank you for your input, and your questions, it gives me a chance to re-evaluate our workflow and look for improvements - something I do often!
Fuzzy,
As always, thank you for your input and support! - your comments are worth gold!
Jim,
thank you for your comment - I must admit, in the ideal world, I would also love one single project, coming from a Server administrator background, I miss the order!
