embeddingApple Keynote limitations - 30 seconds and stop?I've been trawling through the archives, and can't find a unified resource regarding QC integration with Keynote. I've read about the limitation with unsafe patches. I've also know that Keynote won't pass keyboard input, even for keypresses that aren't used by the program itself. What's stumping me is a 30s limitation for playback. I've built a qlitch timer that uses System Time as a source variable, but after 30 seconds it simply stops. If I select for the qtz file to loop in Keynote, it will, but that also restarts the timer. Any thoughts? Rob.
Embedding Movies in Quartz Composer : Image StructuresIt is possible to embed a movie in Quartz Composer, by following these steps:
...and you're done! One should have a qtz that is playing back an embedded movie, with ability to define the rate of playback. For an example of this, reference the attached file. Notes: I've tested this with multi-page pdf's and gif images, though I'm guessing that multi-page tiff would likely work as well. For creating your own from scratch, it's easy to convert movies to Image Sequences using Quicktime's Export to Image Sequence ability. From that point one, can use a utility program to create a gif, or use Preview to convert to pdf. I would think it would be possible to merge a pdf document by using Preview, and according to some unofficial documentation I've read, but when I drop multiple pdf's onto the sidebar in Preview, it doesn't give me a "bound"/merged document. I've used an older free utility called "pdfsam", which will successfully create a merged pdf document with correct ordering. For the sake of size (and cost of quality), one may want to reopen the merged pdf in Preview and Save using the "Reduce File Size" Quartz Filter option. The creation of Image Sequence from movie, to merged pdf or gif file seems like something that should be scriptable, to avoid having to use various applications to prep the Image document, but I haven't investigated the automation of that process yet.
