John you can do some sampling calculations in simple arithmetic to determine what you can achieve. I've done this with some 10 frame animations and compare the *.ani file size with what the uncompressed size would be. At a BLF of 250 QF of 23 settings I get about 11-13 to 1 compression ratios. At 240 it runs 12-14 to 1. This has been pretty consistent. Using the lower QF for rotoscope the ratios vary between 16 – 20 to one. Every frame grab is different. Interesting, you and I have the same question about the "software" limit. Did you ever get the TBC IV ? I just landed a 90 second animation job last week that will have 13 rotoscopes moving on the screen at the same time. It will be mapped on each page of a magazine look using Schreiber page turn and the cover will have the logo use Python. The background will also be a video so I guess this will classify as 14 channels. I'm going to need the larger Mic drive for this. Unfortunately, I will not have the luxury of my network to render this monster since I'll need to import files from the PAR drive and render them right back to the PAR to get everything to fit. Any thoughts for logistics? <G>
