I wouldn't say useless for video. Both do 720p. the T1i at 30fps and the t3 at 25. For one on a budget, that's a pretty good deal. In comparison, I've used both the K-x and K-r from Pentax - both of which offer only 720@25, and I've been satisfied with the outcome of work.
For entry level VIDEO, it's a great deal if you can't score on an evilbay bidding war...
