Yeah there are countless programs to do this outside web browsers some of my favorites of the last 20 years http://en.wikipedia.org/wiki/Scala,_Inc (Amiga tool , see we did stuff too before the web !) http://en.wikipedia.org/wiki/Video_Toaster (another awesome amiga based h/w )

The point is it doesn't take any messing about with web technologies , the people doign this sort of titling professionaly for Sky/Fox BBC are using a combination of broadcast hardware & occasionally Apple Shake in the case of sky sports though i may be out of touch now since shake is not avail much longer.
