Russ, Last night I rendered some animation and when I played it back this morning, the colors are all wrong. Actually, what I am getting is a shift of color. It looks like each frame has different colors in it. Also the image has some registration problems. It is a 130 frame animation, and somewhere in the middle, the bottom of the frame can be seen and jumps almost like a film projector would do if you lost the loop. The last animation I did also had a color problem, but it only happened on a couple of frames, but this is throughout the entire scene. Any ideas of what I can do to correct this? Fred

Fred, Are the color problems in the saved images only or in the Toaster Framestores in general? If your entire Toaster output has garbled color, you probably have something interfereing with the toaster through the parellel port. My Parnet cable will sometimes screw everything up. Later, Jim

Jim, The color problem is only with the animation that I rendered last night. It was rendered to one of the Flyer drives. All of the other files on that drive playback fine. So, it must have something to do with Lightwave while it was rendering. Fred

Hi Fred- Do you have that 'required' test clip still sitting on your Flyer drive? NewTek confirmed yesterday that you shouldn't delete it, but the tech I spoke with didn't know why either. Maybe I'll go to the top today. Afterall, it would be nice to know what it does. Hank Videology, Inc. Where you get P.O.M.P. under all circumstances

Hank, Yep, my Test Clip is on the drive. Let me know what you find out as to why it must be there. BTW, I've got two Seagate 9GB hard drives. Both certified. I am still getting some stuttering. It only happens in maybe two clips out of 50, but it is there. So, we can't blame this on the Quantim. Fred

Fred, The usual question – is there any pattern (timing, same clip, after certain effects) to the stutter? NewTek detailed some on the know bug list. Do any of them fit the pattern/conditions? Hank Videology, Inc. Where you get P.O.M.P. under all circumstances

Hank, The stutter repeats itself five times. It usually happens right at the beginning of a clip or right at the end of a clip. I haven't noticed it in the middle. Both the picture and sound stutter together. It really does look a lot like the Max Headroom TV show. Or like a Woody Woodpecker. Fred

Fred: When you recorded the animation did you use LOCK PALLET? When Lightwave renders a frame it uses an avalible pallet of 16.whatever million colors. when it reduces those colors to Ham8 each frame will end up with its own pallet. When frames with diferent pallets are played in sequence there can be some very noticable shifts. If you use Lock Pallet you can dicide what frames pallet you want to use, and use that pallet for all the frames. Brad Hayes Hayes Visual Communication

Brad, I didn't use LOCK PALLET. I'm not even sure I know where it is, but I'll look. The scene that I rendered was created via Hollywood FX. Now that I think of it, the last three scenes that I rendered using Hollywood FX had a color problem. Fred

Fred: Lock Palette is just under the ANIM TYPE button on the record panel. Next to it is a Lock Palette Frame number. The only time that you really need to worry about this is when you first frame is not the best representation of colors in the animation. For example, a space scene were the camera pans from a black sky to a colorful nebula. Give it a shot, this could be the problem… Brad Hayes Hayes Visual Communication

Brad, Thanks, I'll give it a try. Fred

Fred, PMFJI The registration problem you discribe >>jumps almost like a film projector would do if you lost the loop<< sounds like a problem I have had with heat buildup. With the first version of the software I got back in December this was a constant problem but has gotten better with the last couple of updates. Try removing the cover and adding a fan to cool the three chips. The color problem could also be due to heat buildup. Russ (the other one) Finley Holiday Films

Hello Russ (the other one) I don't think it is a heat problem. The only time I seem to have this problem is when I render something in Lightwave. The video clips look fine. It may have something to do with using Hollywood FX with the Flyer. The first day that I got the Flyer, I had Lightwave render one of the scenes that came with the program. Then I tried one from one of the Lightwave Pro magazine disks. These came out just fine. It has only happened when I try and do something with Hollywood FX. That may be the problem. But, thanks for your suggestion.
