I am in the process of dropping Feedburner, which currently powers this site’s RSS feed. Why am I making this change? Well, recently, Google announced that they are shutting down their RSS reader, imaginatively titled, Reader. All indications are that they will likely shut down Feedburner too. I’d rather get ahead of this possible (and likely) shutdown, is the site’s core feed  and it will not change as long as this blog is active. This feed is exactly what you’ve been reading all along – a combination of my film, tech and tumblr posts. If this core feed is what you have in your feed reader, you are all set. If you have a Feedburner feed ( or, you should update it if you want to keep reading. To add it to your feed reader of choice, just copy and paste the URL ( into your feed reader.

I will make the switch on April 15th.

Thank you  for reading and participating.


Showing invisible motions on screen

The New York Times reports that scientists at MIT have uncovered a way to show the invisible motions of your body, like your heart beat, eye movement etc., on screen. You have to watch the video in the link – it’s pretty incredible.

The system works by homing in on specific pixels in a video over the course of time. Frame-by-frame, the program identifies minute changes in color and then amplifies them up to 100 times, turning, say, a subtle shift toward pink to a bright crimson.

What’s even better is that they have released the source code so that anyone can use it. There are a ton of applications to this, across several fields. But in film, there are immediate and cool uses. I’m betting someone is going to come up with a short film, run it through the algorithm and have it up online in… less than 2 weeks.

Such great work. Thank you, Prof. William T. Freeman and team!
