movieMovie Runner Crossfader (sans iterators)Attached is a proof of concept folder scanner/crossfader I developed for a birthday party. It scans a folder for all movies (recursively) and then plays them sequentially with an 'x' second crossfade between adjacent movies. The movies need to be longer that 'crossfade time' seconds or weirdness will happen (as it's using 2 players and mixing between them). This could be more simply executed by using CoGe or other VJ app, but I like staying in QC as much as possible. Power to the people. p.s. I'd love to know how to make 'virtual patches' or 'macros' inside a patch that don't require external plugins/patches to be installed (i.e. my "movie player" macro is duplicated in this patch, and I'm not sure how to get around this for the simplest method of distribution [which rules out external patches]) p.p.s you could extend this example to have 3,4,5...n dedicated players/mixers, and such a project would be very, very cool. maybe I'll do it myself when I need such a thing.
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.
New plugin - export to movieI'd like to announce availability of new plugin/patch - Export to Movie http://quartzcomposer.com/plugins/1-export-to-movie You can put your composition inside "Render to Image" patch and send it's output as image input to "Export to Movie" patch. Example composition using this patch: http://quartzcomposer.com/patches/332-export-to-movie-example Mirek Rusin
