How would I accomplish this?
I have two photoshop files that have a transparent background. I want to bring them into Vegas Pro 10 and do the following. Image one rotates counter clockwise. Image two rotates clockwise. One will be on the track above so they appear on the screen at the same time. I want to render it to keep the background transparent. How would I do this. I want to be able to place this rendered file (with transparent background) into another Vegas build over the top of other tracks. I hope I explained this so you all can understand what I’m talking about.
Thanks

Rendering output that is “transparent” requires a codec that can produce an alpha channel. The uncompressed avi output from Vegas has an alpha channel checkmark box in the output settings window. Other codecs have alpha channels as well I just do not remember them off hand. When re-importing back in to Vegas you will need to check the clip properties and change the alpha channel (for your purposes “straight matte”.)
Unfortunately I think only the uncompressed codecs can do alpha channels which means huge files for you to import in to your other project. This begs the question whether you absolutely NEED to render the file first. Vegas projects can be nested, copy and pasted between instances, full of layers etc. Are there circumstances that make it impossible to work with your clips natively in the second project?

If you’re asking how to move the images, you can use Track Motion or Pan/Crop. If you use Track Motion, then you can still use Pan/Crop to zoom in/out of the image while it is rotating. Track 1 would have an image moving clockwise; track 2 counter-clockwise. Use Properties, Media, Alpha to enable the alpha channel.
Formats with alpha are .avi uncompressed, .mov animation, and .mov PNG.
But I’d take Matt’s suggestion and nest this project into your parent project(s). That way, any changes to the child project are reflected in the parent project immediately and it doesn’t require another intermediate render step and subsequent replacement in the parent project.

Matt, thanks for your response. The reason I wanted to have it rendered before importing into other projects is because it will be placed several times with different key-frames set for each time it is used. I would like to just have one video file that I can scale, move, etc. The clip length will only be about 5 seconds so the file size may not be a problem if I render it as you say above (avi with alpha channel).
Thanks

When in photoshop I think I would save the files as .png to maintain transparancy, then in vegas after doing all the editing I would just save as a veg file and then just nest the veg file in my new project. If I understand your query properley.
