Well the new question, why do I keep getting black. I have changed the alpha buffers and about every thing I can think of. I know it is going to be something simple but it eludes me.
Any suggestion?

I was trying a Icarus tracking file, so trying to trouble shoot the problem I removed it, saved as a new project and tried to render again, same results.
( I couldn't tell that the Icarus file made any difference with the animation )

Images are with that file included. This is what the render window displays with alpha ON and OFF.

After it finishes rendering the video is BLACK, aghhhh. Every time.

Walt do you have your vidio footage on a layer.if so is there anything else it could pass through
What are you rendering to .movie ,if so you could try TARGA files see if that makes any diferance

yeah, how is that video incorporated into the scene? Layer? Rotoscope? Some sort of Front projection objecy?


Can you post a sample PRJ that includes a frame of video?

the rabbit is in front of the black part

If the footage is a rotoscope projected onto the ground using Front Project Target, then try to set your Output Format to jpg's. That usually fixes it for me

The video is a rotoscope for the camera1, the square block is a 4x4 grid used only for shadows, there is a path for the rabbit to run on.
I have changed all the options in the option section (attached image) every way possible and get nothing much different.
I am rendering to a QT movie.
I am attaching a consolidated file, hoping it all is with it.

the attached prj file didnt include a frame of the rotoscope so here is the first image

the tga file didn't send so here is a jpg

Ok finally figured it out.
In the 'Out put' section....movie type settings I had it set to QT.jpg
so changed them to 'Animation' just a simple thing as usual.
Thanks for the help

Hehe I bet the kids love it ,glad you got it sorted

I had a similar problem with my own Camera Rotos. I imported a 460 tga VGA image sequence, set them to Camera Roto. Removed ground and all the lights in the chor then rendered out and got nothing but black. Render in Shaded mode and I got the roto rendering. Then started mucking about with the alpha options in the camera output and the image sequence itself and eventually got it working.

Cheers

The original is 12 seconds long, after I got the problem figured out I started rendering and at the very end the program crashed so I had a new problem to figure out.
The only thing I could come up with was the length of the video, chor. and render settings didn't match, but finally got it.
I hate having to wait hours while rendering to find out it's not working.
Any way got it and thanks for everyones help and suggestions, thats why this is a great forum!
