Cookie Cutter bug in Vegas 6?

StormCrow wrote on 8/25/2005, 12:57 PM

I've had this happen in 2 of my edits so far (the only two I've used the cookie cutter). What happens is that I set the cookie cutter in a clip and then keyframe it to close all the way down so that all that is left is a black screen at the end. What happens is the cookie cutter starts to close down and then gets so far and hesitates for a few seconds before finishing off "closing out the picture"? There are no otehr keyframes that are deterring it from making a smooth transition from it's set position to closing all the way down. There is nothing in the track above or below it that would cause this either. It is worse the farther apart the full open vs. full closed keyframes are (the hesitation). I'm using Vegas 6.0b on a P4 3.0GHz with 1 gig of Corsair XMS memory and Windows XP.

SC? I've really tried to repro this one. I can't. Are you absolutely sure you haven't got a couple of very very near k/fs hidden one on top of the other? Try e x p a n d i n g the k/f timeline - just to be sure. Try starting again?

Anyways it is working here in London . . .

Grazie, thanks for the reply. I restarted my computer and it made no difference at all. For whatever reason the farther apart I put the kf's the worse the hesitation in the cookie cutter going from open to full close? If I put the end kf closer then you don't notice the hesitation but it is probably due to the speed at which it is closing down. Also there are no other keyframes other than the first one for the event and then the copy of that keyframe later down the timeline so that the size holds until that point and then about 5 seconds later I have another kf to have it close all the way down.

right click on the keyrames and select "linear" motion. It sounds like it's set to "smooth".

Thanks for the reply. All keyframes are set to linear. Still that hesitation as it nears the end where it is suppose to be closed down all the way.

This sounds very similar to the Iris transition effect where there is a hesitation near the end before it closes completely. It only seems to hesitate where there is feathering applied to the iris.

Stormcrow, Grazie, as a matter of interest, when you tried it was the cookie feathered?

Nope. No feathering. Richard I'll try tyhis again PLUS the Iris thing too.

I can NOW repro this. With Feathering I get the "appearance" of held frames; without feathering this "appearance" does not occur.

I think there is some involved "calculus" going on here. As the variable diameter of the "hole" gets smaller, the ACTUAL width of the feather - NOT border - momentarily appears to not marry-up with the reduction of the hole. The feathering does reduce but appears NOT to sufficiently to catch up with the diameter variable.

So 2 variables going on here: vDiameter and vFeather

Now, in-everything-Einstein, how Madison can/could marry these 2 variables to be interactive enough to catch up with each other, I really wouldn't know!

As I say this is my opinion and also there is an appearance of "held" frames. I think it is an interim thing going on, whereby the "softness" of the feather within the border is being itself being carried across the surface of the feathering. The feathering is continuing to be reduced but the nature of feathering in itself gives a variation of depth across its OWN width.

Sorry, can't be more specific.

Hi Grazie. Thanks for taking the effort to repro this with feathering.

You explanation is way over my head, but i just wish Sony would fix the bug. Whether it is the "correct" way to calculate the feathering or not, visually it always looks like a glitch to me and I don't believe it is the desired effect.
