This infomration mostly comes from the description of the QTTime struct, whose values include timeScale and timeValue. Check out: http://developer.apple.com/documentation/QuickTime/Reference/QTKitFramework/Miscellaneous/QTKit_Functions/index.html It’s similarly vague. Then again, its not as bad as: http://developer.apple.com/documentation/QuickTime/Reference/QTKitFramework/Classes/QTMovie_Class/Reference/Reference.html#//apple_ref/doc/c_ref/QTMovieExport (“Information to come”…) that I had to figure out to export movies. Ugh. Far more helpful is to look at the FAQ: http://developer.apple.com/technotes/tn2005/tn2138.html where some code snippets (ie the ones using the makeTime function) make it fairly obvious what is going on. I am totally in agreement that if the reference for API is bad, it is as bad as writing a bad GUI for an App. On the other hand, I’d rather have an undocumented API to an unsupported one, and I’d even rather have the later to an non-existant one… Gotta go catch the 41=). william

Ah, OK. That does make sense – I guess it might change for some kinds of movies or something. Thanks – I wonder if you can put links to further web documentation in your scripting dictionary. That might have cleared things up here and kept the duplicate work down for the dictionary author…

Michael, If its the same as the Cocoa QTKit (which has the same lack of comprehensible documentation), then time scale is 600 default, and refers to the number of intervals within a second. So for the default value, the scale is 1/600th of a second. So the current time would be in 600th’s of a seconds. I had the same problem and I only learned this by trail and error (and a bit of help from some Apple sample code…). hope that helps… william
