QtzRendang in action

Announcing QtzRendang, a little utility app for rendering Quartz Compositions to movie files. I cobbled this together from example code for my own purposes, and since I couldn't find anything on the web. "My own purposes" typically involve rendering a loopy composition to a six or seven minute movie to make simple but effective videos for Cartoon Beats releases.

By the way, there is another app for this purpose developed by the Kineme crew - QuartzCrystal - which supports spatial and temporal oversampling to reduce temporal and visual jagginess. At US$18 this is a great little app, but as I'm a bit of a nerd and a cheapskate, and there wasn't an open source solution, I decided it was worth writing QtzRendang.

CoGe is another great project on Google code. It's an open source visualisation/VJ mixer/live sequencer.

Back to QtzRendang


Drag & drop a composition, specify frame resolution, duration, and frame rate & output filename. Optionally tweak composition parameters, then click render.

Why is it called QtzRendang? Well it renders .qtz files to movies, and the instant noodles I had that week were rendang flavour. Rendang is a slow-cooked Indonesian dish which seems like it would be pretty yum. I've never had it.

Any questions about the software itself please feel free to ask in the comments.
Since the dawn of Mac OS X, new-to-the-platform users have cried "but the font is huge" followed closely by "can I really only choose between blue and grey?"...

I don't have a solution for the second problem, but I have a sorta-solution for the first one, and it got me pretty excited.

I saw a tip on TUAW explaining how to put the date in the menu bar. This got me pretty dang excited because I always refer there, and up til now had to click to get the date. This tip also has the added feature of allowing you to show the date as numbers, which is great, because usually I have to count on my fingers to determine what month it is.

Anyway, back to the point, by having a date format with this guy "/" in, I believe has caused the system font to be bumped down a notch (presumably to accomodate the date in the menu bar), and lemme tellya, it looks so much better. All the system context menus everywhere are using this slightly smaller font, and all the app menu bars too. I'm so pleased, everything is a tiny bit smaller.

Are you worried? I'm not, clearly this is a weird side effect that could disappear at any moment, and still only gives you one other font size choice (oh, and I haven't tried switching back, maybe it's broken forever). BUT how great does it feel to make a 0.5-point (estimated) change to the Mac OS X system font?


FORKING INCREDIBLY GREAT.
