Don, >> Interesting, you and I have the same question about "software" limit. << It is an interesting question whether its a software or hardware limitation. At 255 that would imply an 8 bit compression ratio, which would explain why the Max is going to use two drives, one for each field, to obtain a lower compression ratio, as the minimum compression is being applied to half as many pixels with fields. Which would suggest a maximum of 7.5 Mb per second throughput. If this scenario is correct then the only way to get lower compression ratios is to build a disc array like the Abekas and share portions of the picture on multiple drives to approach something on the order of an 8 to 1 ratio. No, I never did get a TBC IV. I opted for the Exabyte instead, as a) I can reverse the process and send a post house a beta sp tape and have them send me individual YUV frames for rotoscoping on tape which I can download as needed; paint and put back on another tape without losing the original, b) its an excellent backup system, c) I can store large amounts of pictures (5 gigabytes) @ for $12 a tape, d) its fast and the tapedrive is networked so with multiple machines there's little delay. e) Picture quality is not compromised. Now if I could just find a paint package that will import YUV files without haveing to convert. The process is fast on a Pentium and in a way has benefits in that you don't get the frames confused but… The new Adobe Premiere for allows you to do this, but wouldn't you know it… its for the Mac. Maybe I can convince Ron Scott to support YUV. <g> John
