I have yet still to find a decent video capture app for OSX
Definitely use Snapz Pro X. It's hands-down the best because it essentially renders the video AFTER you're done working on it, ensuring a higher frame-rate during whatever you're doing as well as better quality videos. Also has a simple check-box to record outgoing audio. If you have something you want capped right away there's a 30 day full-feature trial anyway...
Joined the group, it's too bad that Vimeo has such a draconian policy in place. Unfortunately, Youtube isn't much better. While I don't know of anything similar to the policy outlined above I do know that a rightsholder can issue a take down notice and have your video removed regardless of whether you actually infringe on his copyright. What this means is a game critique/review of, say, Metal Gear 4 is just as likely a candidate for take down on Youtube as on Vimeo. Hopefully businesses will come to their senses and stop treating customers like crap soon.
But on YouTube that's up to the right's holders.
They'll be douch-bags no matter what unsanctioned service their video is on. Vimeo just takes down an entire swathe of videos based on their content. They took down 2DBoy's and Wolfire's videos without so much as a warning AFAIK.
