I wanted something to use to do subtitling and since a) quicktime is a supported Elan export format, b) I can download the reg key without a huge amount of bandwidth here, and c) it’s not too expensive, I bought the pro version of Quicktime.
Not too impressed so far. The help files refer to items which don’t seem to exist. It crashes a bit. Still, it does what I want it to for now, which was, in particular, to make a slide show of frog story pics with the language audio and subtitles.
