composite wierdness

Anyone heard of anything like this:

I got a short sequence in VV 3.0c with one still image being panned on track 3. This acts as a background for five stills on track 2 that float accross the screen one at a time using pan/crop, Track motion and cookie cutter.

It all looked perfect in the preview window, but when I rendered, four of the five fly-bys simply didn't appear.

They were originally jpgs, so I changed them to PNGs, since that seems to require less decoding, reloaded each image and separated them to appear alternately on two tracks. I even did short renders along the way as I was re-doing them, and they all rendered ok. Until I finished and rendered the whole sequence. I now have four that work fine, but one still does not appear in the render. I can find nothing different between the ones that work and the one that doesn't.

Any ideas?

You can put the timeline into a mode that is equivalent to rendering by setting the Video Preview to Best quality, right-click on it and turn on "Display at Project Size", and match the output frame size and frame rate in the Project Properties dialog. Then, you can step through the problem areas frame by frame and figure out what the issue is. If you can't grok it from that, we can arrange for you to FTP the .veg and whatever files are under the cursor at the problem area, and we'll get to the bottom of this. Or, top. Sorry, bad layering pun.

Dennis:

Thanks for the suggestion. I tried it and the preview still looked fine--if real slow. Couldn't see anything I didn't see before.

You want to take a look at this thing? I can save just the problem section of the .veg and send you it and the five images involved if you give me an address. It won't be too big.

Thanx.

Sure, I'd love to figure out what's going on. I'll be in touch via email.

Widetrack:

I figured out what's causing your images to disappear, it's a bug in the Cookie Cutter FX being used on the pan/cropped images. If the image width or height gets smaller than the feather radius, at least with the default "Rectangle" shape (maybe others), then the image disappears.

For your projects, without changing any of your pan/crop settings, you can decrease the Cookie Cutter "Feather" or increase the "Size" parameters to fix the disappearing images. We'll fix this bug in the next update. I'm sorry that it has caused you problems, and I thank you for working with us to identify the issue.
