Sorry but your numbers are more than a bit off.christoph wrote: obviously time is not worth a lot to you. a workprinter does what? 6fps? (and in HD uncompressed probably even less?). now lets say somebody wants you to transfer 5 hours of footage, that means the workprinter is chunking along for 20hours, then you have to load this into an editing sequence and watch it all to appy color corrections, which takes like 6hours if done properly, then you'll have to render and play it all out to tape/export to disk (another 5 hours) so you'll be sitting there two long days longer than a real time transfer with on the fly color correction.
First the WorkPrinter and Sniper units transfer at almost 9fps (we list them at 6fps to be conservative) but they run at about 8.5+ fps. That means a 4.5 minute roll of regular 8 will take about 8.5 minutes to transfer, which is about half speed. The HD transfers that Eugene is doing uses 12 hard drives in a Raid so he is also operating at top speed of the WorkPrinter.
Second, not all home movie film is shot at the same speed, so if you are concerned about giving the client correct framerate on playback and you use a real time transfer unit, then you have to man the entire transfer looking for speed changes or you have to guess what speed their footage is because it is a cinch they will not know since these are grampa's films, usually. But with something like the Sniper-Pro or WorkPrinter you are not concerned about the frame rate during the transfer because it is simply capturing frame by frame and can do so unattended, which means that the operator can do other things during that time for maximum productivity. Speed changes are handled via CineCap in a batch process which, again, does not take up any employee time; only computer time and that employee can be doing other things that are productive while the speed change is rendering out, which is fast, compared to the length of the actual film.
Third, only a goof is going to run a video business on a deadline basis and have to render out their color corrections. The Matrox RTX system, available in both SD and HD, offers real time color correction with no rendering of any kind and is only one of several real time systems for working with DV files that are very affordable, especially for a business.
Finally, your term "on the fly color correction" is a bit misleading. If you have an hour of film to color correct on a Rank or any other real time programable system, you certainly aren't going to color correct that in less than an hour unless it is an hour's worth of the same shot. You are going to program it in, shot by shot, and then rewind the film, have it cleaned, find the synch point and THEN let it run in real time which, of course, is going to be an hour as well. So, at a minimum, an hours worth of film is probably going to take about 3 hours, which is why Rank houses charge X3 when they quote you a price.
Color correction on a computer that has real time CC without rendering is very time efficient, compared to color correcting in real time on a system that can not be programmed where you have to stop, make you color correction, rewind, start, run to tape for a bit, then stop, rewind, make another color correction, start tape again, etc.
I have used this analogy before but it is the most accurate way to look at this: Before Ford came up with the assembly line, cars were built by hand, one at at time. It took a team of 20 guys about a week to build one, if they really worked at it. Ford's factory also took about a week for a car to come out the other end but the difference was that a minute or two later, another car was coming out and another after that in a continual stream of output where volume increased because of efficiency.
Likewise, the only real delay in scanning at a slower speed if it is automated is the initial time getting the first job through the system. After that, there is a constant stream of output that comes out faster than you can color correct and burn off to DVD or tape. It's all about how you structure your workflow. For instance, if I had something like the FlashScan, I would run everything at 30fps (for NTSC) while I did something more productive, and then let CineCap do the speed changes on a cheap computer while I, again, did something else more productive, and then color correct on the computer where I don't have to sit through a 30 minute scene in real time to know that it has been color corrected properly. I can drag my cursor through it rapidly and make quick cuts and color corrections in real time without rendering and then it's ready. In short, an hour's worth of color correction on the computer can be done in far less than an hour because it isn't linear time.
I've been in the transfer business for years and, believe me, the issue isn't speed. The issue is the number of paid manhours per job. There is nothing wrong with scanning at a slower rate as long as your employee can stay productive doing other tasks. He can't do that if he has to man the entire transfer looking for speed and color changes. People have figured this out on their own which is why we sell the frame by frame scanning units 20:1 over our real time units, which are actually cheaper than the frame by frame units.
