Image ImporterImage importer speed up?Hi! I have a problem with the image importer patch. In my composition I have a basic directory scanner -> image downloader -> billboard chain+syphon client. In the folder there are several thousands of images, all max 1440x1080, medium to low jpeg settings. The goal is to show them smooth at 30fps and record it with syphon recorder at FullHD/30p. However, the composition does not run steady at 30fps. Photos from my digital camera run at max. 20fps, whereas other images (screenshots, isight photos, etc) run at 30fps. Everything runs really fast, but the difference in speed between the different kind of images are really noticeable. Moreover, I sometimes get a "black frame" when loading the next image happens a little too slow, and that also shows up in the video recorded with syphon. In some cases there are even some glitch effects in the syhpon video or the recording breaks. I have an 2011 MacBook Pro, running Snow Leopard with 8gb ram and a AMD Radeon HD 6750M Graphic with 1gb. Is there a way to speed up the image importing process and balance everything? There is an option called "Maximum Cache size"in the image importer patch, but it only caches the past images. Quartz Crystal works fine, but it is necessary to run everything in realtime. thanks for your help, Sebastian

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.
