Wow. That is some SERIOUS editing. I thought I was pushing the envelope with my current project, involving 19 tracks (15 video, 4 audio). I'm just finishing up a DVD and I'm making the Main Menu, and it's a motion menu full of video thumbnails and the like. On some renderings I've gotten the rendered frame rate down to about 1 per second, a new high (or low) for my 1.3GHz T'bird.
My main system with the veggies is undergoing a reload after a software meltdown :) From my best memory, Just under 1000 events, from 8 hours of raw footage that captured in about 480 media files.
I had one project that had only 600 ish events but used 21 tracks of video to composite it. That was the real hog of a veggie.
I expect the upcoming project to be twice as long as the first project I listed, Since the style is the same, that means I will using more than 1500 events and probably 800 or so media files. Yuk. I am glad I am on an NLE! Especially Vegas.
I did one that was 2800 still images in 2 minutes and the images certain images are actually synced to the music. Kind of hard to explain but it was pretty complex and I actually had to figure out the timing with a calculator.
2800 stills total, but alot of them were duplicates, there are about 800 actual stills I took over a few years with a digital camera.
Other than that kind of stuff, I am working on a project now that has taken up 50 DV tapes. Multiple cameras (up to 5 angles) and secondary audio. I am doing it piece by piece tho, not one overloaded veg.
Stage musical show-3 cameras,3 nights,104 minutes finished length. 9 vid tracks plus 3 more for some compositing/stills/etc. 9 aud tracks (from cams; just for sync) plus 2 more from sound board. 27 separate acts; about 40 or 50 events per, average.
I mostly used a sort of A/B (and C/D/E/F....) roll technique instead of cutting clips. I set an opacity envelope for each vid track, and just ran up the envelope for the track I wanted. So I didn't have very many "media" open in the pool.
