At some point in time I must have installed what was necessary to import .mov files into Vegas Pro 13. However, when I opened a v13 project in Vegas Pro 14, and selected the appropriate .mov file source, it rejects it.
So, what do I need to install/configure so that Vegas Pro 14 supports importing/using .mov files? (Note: I don't need to render as .mov -- I just need to be able to use those files as source material.)
