More great stuff.
So I noticed that some of your vids are just taken by camera off of youtube.
I use Firefox browser which lets me, with a few cool add-ons, to download the vids directly to my hard drive. Were you aware of this fine, and easy technology? Might make your work significantly easier. Did for me.
The one I am using currently, downloads the vid in many different formats, as I like, with the click of 1 button, embedded right on the youtube page.
It's called "1 click youtube video downloader", but there are many good ones out there. Totally worth checking out.
