Well... after figuring out how to salvage my account from the "you only had it as a trial" monster I finally decided to crack this thing open and figure out how to post videos.
Posting videos on Squarespace has nothing to do with uploading your video. As a matter of fact they just want you to embed your video that is posted on Vimeo or YouTube. For a brief moment I thought, "hmm, am I gonna have to move all my tutorials to YouTube?"
That Prospect scared me because, frankly, I do better compressions then they do. Then I messed around until I figured out how to keep my QT movies where they were on my other site and just drop an embed code into am HTML page.
Maybe I'll have to put up a tutorial on how to do that?
