OK, I will add my two cents. I have also been lurking with interest.
I don’t have any idea how 25,000 items can be in one project. I am totally perplexed by that. I read the posts and still don’t get it. With the exception of importing projects to get at one small part. I understand that and can only suggest that you copy the project file and start deleting sequences until you get to what you need, then delete any file not referenced. Then import it. This is certainly a problem.
If items are not in use, get rid of them. I understand the ease of importing entire directories as bins, but not if you only need a few items. I understand the idea of chice, I believe. I do understand the need to be able to easily access all 25,000 items or more. Don’t get me wrong. That is what the Adobe Bridge is for. Or, will be, when they get it right. You should not have a clip in the project until you are ready to use it. It is just too easy to add media as you require it.
I admit that I use two monitors. So I can work in one and use Bridge in another. Drag and drop and away we go. I can tell you that when I use the Project Manager to move a project to a backup disk, I seldom save more than 10 percent of the space. This is also because I scene detect my captures with a 3rd party application and only import the files I want into my various projects.
As for preview files, I regularly purge those as well, Since I often nest sequences and renders don’t stay with the nested sequence, I often delete all of my preview files and rebuild them as necessary. I hope this changes one day. We ought to be able to delete out-of-date renders with a simple menu selection. I often do this during lunch or dinner breaks. Or even overnight. If you are exporting files and bringing them back in to replace original material, then get rid of the original material. It’s easy. Sort by usage and select everything at once that you need to delete. It isn’t like you were deleting the actual file.
Keep in mind that a Premiere Pro project is not a real database of items. It is an XML file. Text. All of which has to be read into RAM. It is not a random access file as it probably should be.
I find that when I am working a large project for a corporate customer, I make several projects so I can handle scenes or sections of the video separately. I then export a DV AVI (or CFHD AVI lately) to use in the project I designate as “Main”. I get everything ready in various projects, combine exported files to organize a “almost final” project, and make sure it all looks the way I want it to look (think “proxy” files). Then, after that, I can import all of the projects, replace exported clips with nested sequences, and then just about all I have to do is export the final product.
With DV this was more important as I exported to MPEG2-DVD. With HDV, using the Cineform AVI, it is less necessary due to the wavelet technology that provides me with the quality I require without noticeable loss in only one generation. My exports to WMV-HD come out just fine if I just use the exported files.
When projects are kept lean, opening them takes seconds, not minutes. So switching back and forth has never caused me much heartache. Besides, while I have never lost a file to corruption, I figure my day will come. Better it should be once scene and not an entire presentation.
I also find that I use After Effects to do a lot of work with tiny little clips or stills. Using Dynamic Link to a comp with 1000 items is a lot easier than dealing with those same items in Premiere Pro.
Obviously there are problems with Premiere Pro. But working with the software instead of against it is something that might make your life less stressful.
Hmm. Maybe this was more like three cents.
