This is a patch I have made to play certain clips at the correct moments in an audio/visual installation.

The problem with this patch is that in the patcher which makes the video fade in and out (found in the video player sub-patcher), the metro that makes the video clips play randomly is too quick for the trigger which makes the clips fade in and out to white (or black).

I think this is because of an issue to do with the metro being timed with Max time format syntax in opposition to the other triggers being timed by the qtunits of the movie files.

Any ideas how I can turn qtunits in a units which the metro recognises? or visa versa?

Hmm, your patch is too big and chaotic to quickly understand. Why don't you give subpatchers names? And why do all these sends (like [s act1intro]) all point to the same thing? Sends like [s you] and [s bang1] aren't making things clearer...

Seems like you need to know when a movie finishes, then start a new one (or fade between the two in some way)? I would use getduration to a jit.qt.movie object, then convert to ms using gettimescale. Then you can trigger a delay, metro or whatever to fade to the next movie after the appropriate time has elapsed.

As soon as you load the next movie, get the length of that as well, and you know when you're moving onto the next one.

in addition to bas's good advice, here's a patch i give to my class which breaks down the qt timeunit stuff. might be of use.
