| Funny timing. I've never been a fan of timeline b/c I was 'grown up' on Adobe beizier curves and it irritated me how easy it is to knock a whole curve out of place in the TimeLine patch graph editor when I first started using QC.
Anyhow I end up using TL patch last week to make some movie titles as I had a tight deadline and someone looking over my shoulder so didn't want to get stuck on too many mathematical dead ends using chains of interpolation curves like I usually would attempt as first option.
I set the transitions over a nominal ten second period and connected a Interpolation patch that counts from 0 to 10 to the Timeline external time input. Then I tweaked the Interpolation duration input to make fine adjusts to the overall playback speed. I feed the Interpolation patch external time input with a Stop Watch patch that was triggered by a patch time value. I could just have easily done this interpolation curves but thought I'd give Timeline a run an it was a positive experience for once :-)

Description: application/quartzcomposer
I rendered out in Kineme Quartz Crystal with motion blur set to 8. Unfortunately I couldn't get Premier to recognise the Alpha so I had to use the outputs in Lighten/Screen Blend Mode which was frustrating. I was outputting as H264 which I thought has an alpha channel?! It seems from this thread on Stack overflow H.264 Alpha is not implemented widely outside of Apple QT Pro. Also I couldn't find a way to get Premier to input a TIFF sequence which is a industry standard way of bringing animation in over film footage in FCP.

This allows you to set up complex interrelations between Tweens and outputs, but scrub through them simultaneously. Additionally, using a non linear curve in interpolator gives you natural easing. It's quite handy for things like camera interesting camera moves, etc. Additionally, you can set up normalized offsets, like 0 -1, 1 -2, 2 - 3 in 'timeline time units' that have different movements, and by simply offset the time going into the timeline by an integer, you get different 'scenes' or 'looks' naturally.

Great! So simple indeed... Thank Achim.
Tamas, I see that Pharrison's solution also works, hugs to him as well ;)
Thanks, Ali
Very nice solution! Hi Ali,
my suggestion is that you use the "Patch Time"-Input of the Wave Generator instead of the period. (You will get it if you right-cilck on the patch and select it in the menu) You can easily control the speed of time then with an Integrator patch. See modified composition attached.

Hello list,
I'm working on a basic puzzle in QC, may be somebody can come up with a simple smart solution...
I'm trying to control the period of this sphere's diameter live:
<breathe-01.qtz>
I'm trying to eliminate the jump in the diameter value when I change the period of the LFO.
We tried the smooth patch but it doesn't do the job perfect:
<breathe-03.qtz>
Any alternative solution ideas?
Thanks,
Ali Demirel
