What video compression geeks do when they have a spare morning and a camcorder (and a friend who can edit).

Here’s a video from my presentation at Streaming Media West in Los Angeles in November 2011. There’s also a link to the PDF of my Powerpoint slides below. Enjoy.

The future of CDN-delivered video is cacheable, HTTP streaming, with MPEG DASH ultimately taking over, says Highwinds' Chris Bray

Here’s a video I produced for OnlineVideo.net on using Premiere Pro’s Ultra Key and Garbage Matte. It’s an intro- to mid-level video that applies the effect on three videos of varying complexity. The good news? One video is of a (fully clothed) lovely dancing lady. The bad news? The lady’s face is not showing (those pesky permission issues) and the …

I produce lots screencams, and some customers like having a live greenscreen video intro in front of the screencam. “What’s the harm,” they ask? It’s only 30 seconds of video, how long will that take to shoot?” Well, if you’re like me and you don’t have a dedicated studio and staff for such productions, they can take awhile. If fact, …

GoDaddy.com aggressively advertises videos on television to convince you to visit their web site. With celebrities Danica Patrick and Jillian Michaels on board, it’s a pretty good strategy.

In my latest survey, the average video configuration was very close to 640×360, with a combined audio/video data rate of 837 kbps (758 kbps video, 79 kbps audio). This computes to an average bits per pixel value of .115. If videos posted on your site are lower than these figures, you’re probably being unnecessarily conservative. I track the data rate …

This article discusses what data rate is and why it’s important, and what bits per pixel measures and how to compute it.  What is Data Rate? Data rate (or bit rate) is the amount of data per second of video, usually expressed in kilobits (kbps) or megabits per second (Mbps). When I say that ESPN distributes their video at 800 …
