I was recently asked to create some fullscreen video ads for Yahoo’s login page. The constraints were: dimensions of 1440×1024 but less than 500k file size, must loop seamlessly and no HTML5 blend-mode effects or plugins allowed – otherwise an overlay of the steam blended onto a canvas layer would have yielded an even smaller file size. Unfortunately, at the time of writing, Microsoft’s Edge browser did not fully support blend-modes – hurry up Microsoft! I managed to create a few videos, such as the one below, all within these constraints, using After Effects and the amazing WEBM format:

Webcam Flames
I played around some more with my webcam today and knocked this out. I also found my webcam already has the IR filter missing (cheap webcam), so it can already see infrared… which will come in handy:
Mercedes Bend – Physics based banner animation
What I love even more than doing animation, is doing challenging code-driven animation.
This banner actually won some awards apparently, including NMA Campaign of the Month and was shortlisted for Cannes Lions.The line dynamics itself is just Hooke’s law stuff – basic physics. Took some experimentation to get a smooth curve drawn through a series of points (basicaly, the control points of your previous and next points need to be in line).
If you can’t see the demo above because you’re on mobile, or don’t have Flash enabled on your browser, you can see the banner in action below:
The cars follow one of the line’s points with differing elasticity and damping, but the real pain in the backside was drawing the dashed line via code, in crummy ActionScript. Luckily, I’m a persistent bastard 🙂 Read more about it on Bannerblog.
Fun with noisy filters
I’ve been playing with animating perlin noise and using it at a displacement map. Here’s a little example of what I mean (source).
