I think these are some simple questions, but I can't find the answers on my own as I'm new to Vegas and creating AMVs in general.
1. How do I mute the video but not the audio in Vegas 7.0?
2. Are there any previous versions of Vegas I can use for free? I'm on a 30 day trial.
3. Do I need the .sfk files? They keep popping up on my desktop, so I just want to know if I can get rid of them without effecting my upcoming projects.
