The Secret to Go Daddy's Video Success...

...is NOT how they encode their video. But, they do a lot of other things right with their streaming video as you can read below.
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. Of course, when most viewers see these TV commercials, they probably wonder how it ends, and how close the two beauties come to baring all. Me? I wonder how Go Daddy is encoding their video and how social media-savvy they are when it comes to their player.
Average US Broadcasters Streaming at 837 kbps Total Data Rate
- December 5, 2011

I track the data rate and video configuration used by broadcast sites since they indicate the types of streams that their mass market audiences can retrieve and play, and also the quality of streams that web video consumers are used to viewing. In my latest survey, the average video configuration was very close to 640x360, 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.

Everything You Ever Wanted to Know About IDR Frames but Were Afraid to Ask
- December 27, 2011
- 2 comments
Depending upon your encoding tool, you may have access to a checkbox or number box that controls something called IDR frames. What are these creatures and what is their significance? More imporantantly, what's the optimal setting? Well, let's just say that if you're seeing anything like the random blockiness in the picture below when you drag the playhead back and forth within your video, (click the figure to see it at full resolution in a separate window), you're probably using the wrong value.
Read on and I'll tell you why and identify the correct value.
HLS Presets in Compressor Defective: Download New Presets Here
- December 22, 2011

I was noodling around in Compressor 4's presets, and noticed the presets for HTTP Live Streaming. "Hmmm," I thought, "I wonder if Apple chunks the files and creates the required manifest files?" (Didn't in my tests). Then I pondered, "I wonder if Apple's presets match their recommendations in Technical Note TN2224?" So, I opened all the presets, recorded their encoding parameters and compared them to the Tech Note. That's when things got interesting and I found (what I think are) errors in two of the presets.
Choosing production tools
Creating a Perfect Green Screen Overlay in Premiere Pro.
- January 25, 2012

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 other videos are of me.
All joking aside, if you've never used Premiere Pro's Ultra key and you plan to do so in the near term, the tutorial is worth a look.
HP EliteBook 8760W - the Ideal Mobile CS 5.5 Workstation
- November 14, 2011

Depending upon the project type, rendering with GPU-acceleration in Creative Suite 5.5 can reduce rendering time by up to 92% over CPU-only rendering. Since NVIDIA's CUDA technology is the only GPU that currently accelerates rendering in the Adobe Media Encoder and Premiere Pro, buying a notebook without NVIDIA hardware for CS5.5 production is a huge mistake.
If you're in the market for such a notebook, the HP 8760w is a dream machine that performs as well or better than a single CPU desktop workstation. If you need an external eSATA drive for production work, the Akitio Taurus Mini Super-S LCM should be on your short list.

Configuring Your Streaming Video (for Newbies)
- November 29, 2011

Configuring your video streams properly requires an understanding of three concepts; data rate, resolution and frame rate. In this article, I'll define these terms and discuss the influences that impact your choices for each parameter. Then, at the end, I'll walk you through a decision matrix designed to help you choose the optimal parameters for your streaming video.
While this is designed for newbies, the concepts discussed will be valuable to all streaming producers, particularly the information regarding the average bitrates used by broadcast, business-to-consumer and business-to-business sites. Sound interesting? Well then, click over the main article to get started.

Why 30 seconds of video takes 3 hours to shoot
- January 20, 2012
- No comments
I produce lots screencams, and some customers ask for 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, this week I had to shoot two video intros, and it took 3 hours to produce them. So, just to have ammunition for higher fees next time, I figured I would detail the gear I had to setup and configure to get the job done. As an incentive (har, har), those who stick around to read the story will also get a look at the final video.
Normalization and Compression in Adobe CS5.5
- September 18, 2011

Streaming viewers will tolerate some video degradation but expect audio to be near perfect. There are two techniques you can use to make sure that your audio loud, clear and robust. Normalization increases volume as much as possible without introducing distortion into the file, while compression makes the signal as robust as possible. In this tutorial, you'll learn how to apply normalization in Adobe Audition and Adobe Premiere Pro, and how to apply compression in Adobe Audition.

Here's an except from my (Jan Ozer) new book, Video Compression for Flash, Apple Devices and HTML5.
It’s important to recognize that when you deliver video over the Internet, you have multiple options, including streaming, progressive download and adaptive streaming. Note that the mode you choose may have a significant impact on how you produce your files.
