I realize this may be off topic, but I'm new at this stuff and I'd like some input as well. This question does pertain to getting the right footage to let CompositeLab do what it is coded to do. I went to the fxhome.com site, clicked the Products Tab, CompositeLab Pro, then the Technical Specification Tab and scrolled down the page to where it says Supported formats and I/O - Apple Quicktime .MOV - Directshow .AVI - Still images: PSD, BMP, JPEG, PICT, PNG, SGI, TARGA, TIFF This tells me that a virtual set file with file extension .mov or .avi would probably work with CompositeLab Pro. Then I Googled "Virtual Set .mov for sale" and got tons of hits for green/blue screen backgrounds, both digital backdrops, read photo, and motion or video backdrops. Problem is most of those web sites don't tell what format the the files are in. Some of the sites say the backdrops will will work with most NLE editors but no specific file extensions. So there are lots of sources on the internet, like www.digitaljuice.com,
they have daily sales on motion and still backdrops from six or seven bucks and up. A bit more pricy is www.tubetape.com.
I've purchased some backdrops from both and don't feel like I was ripped off, however, you do get what you pay for. Seems like the realistic sets start at two hundred and up. Why don't you go to a landmark in your area on a lightly to moderately overcast day and get some footage there to be used as a virtual backdrop. Seems like a slam-dunk using the same camera to film backdrop and talent to be composited together later. Even eaiser is to create your own set in PhotoShop or Corel Painter, break it up into layers and use the layers with a transparent areas to let the talent move behind and infront of elements in the backdrop. I haven't done much of this yet, so maybe someone with more experience could chime in here with some practical tips and tricks to make this work.
