Working with Quartz compositions in Modul8

In Modul8 you’re able to play Quartz compositions (.qtz files) just by dragging them into your media bank like any other movie. However there are a number of problems with this approach: No 1. Performance. I have done tests and often there is a severe drop in framerate for qtz files in Modul8 compared to the framerate in the Quartz Composer editor. No 2. You cannot decide the rendering size of .qtz files in Modul8 (in version 2.5). They are always rendered as 640×480. In Modul8 v2.6 you can set the size in Preferences but there may be many situations where you’d like to set the size for the individual files. No 3. You cannot set the duration of .qtz files in Modul8. Duration will always be 30 sec. I find that these problems can be solved by following the steps below and converting the .qtz file to a .mov […]

Quartz Composer performance in Modul8

I’ve been doing some testing and it’s my impression that you get a much better performance in Modul8 if you convert your .qtz files to .mov before importing them to Modul8. This can be done by following the steps described in this article: Working with Quartz Compositions in Modul8 I don’t know the reason for this so I don’t know if it’s a general problem or something that is limited to my OS/hardware combination. I’m running Snow Leopard on a 2.4 GHz duo core Macbook Pro. So if you’re curious here are the files that I’ve tested with. I get approx. 14 fps with the .qtz but 57 fps with the .mov in Modul8. In Quartz Composer editor I also get around 57 fps. particleleaves 6 (mov) particleleaves 6 (qtz)

Rendering Quartz Composer compositions

If you have made a Quartz composition you might sometimes want to render it out frame by frame to another format. Here is the way that I found to get the best quality: 1. You need a Quicktime Pro license, which is a paid upgrade to the free Quicktime Player. Get it – it’s useful every day when you work with motion graphics. 2. Open the qtz file in Quicktime Pro. 3. Hit ‘Save as’ and set the duration you want for the final movie. Now the file has been saved as a .mov file, but we’re not done. The file is still basically just a .qtz file in a Quicktime packaging. Step 3 4. Open the new .mov file in Quicktime (if it has not automatically opened in a window already) 5. Hit cmd+J to display the movie properties 6. Click on the second line where it says Quartz […]
