When I try to "edit" one part of a project to other, I set a loop region of the project that I want to take to the other instance of Vegas and do a copy / paste to that.
It works ok when there are no track motion or crop key frames aplied to it.
But when there are track motion or crop key frames, they are not "transfered" to the other instance of Vegas when I paste the loop region selected.
Is there a way to copy and paste all region selected between two Vegas instances, including the track motion / crop key frames?
Thanks

While Pan/Crop keyframes can be copied (copy - paste event attributes, one by one), Track Motion keyframes do not :(

there is a way to do it.
Save your project with a new name
delete everything except what you want in your copy (hit D twice and marquee what you dont want,
or,
hit Control A, select all, then hold control and de select what you want to keep)
Save again to keep your new trimmed comp.
Go to your other instance of Vegas and drag in your copied comp (Veg file) from Windows explorer.
Done.

Or just nest the VEG file in a new project and then trim it as desired...

Thank you for your help.
