Encoding for Adaptive Streaming - From Streaming Media West

Here's a video from my presentation at Streaming Media West in Los Angeles, and a link to the PDF of my Powerpoint slides.

Final Cut Pro X (10.0.3) gets Multicam

Check out my review in OnlineMedia.net, where I found FCPX's multicam feature "fabulous" and concluded: Looking at the bigger picture, Apple deserves credit for delivering on a promise and doing a largely good job of it. Functionally, Final Cut Pro...

Highwinds Completing Transition from RTMP to HTTP

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

Creating a Perfect Green Screen Overlay in Premiere Pro.

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.

Why 30 seconds of video takes 3 hours to shoot

big picture 2.jpgI 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.

Creating presentation videos with slides and video? Check out Presto!

I recently reviewed Singular Software's Presto for OnlineVideo.net; you can read the review here. As the lead states: Capturing and producing presentation videos typically involves multiple options, all of them bad. For example, you can frame wide an...

FFmpeg Encoding Resources at Sonnati Blog

One of the brightest stars in the encoding universe is Fabio Sonnati, who blogs at Flash Video Technology and Optimizations. I was researching H.264 encoding parameters and revisited his site, noting that his presentation from Adobe MAX2011 entitled ...

Everything You Ever Wanted to Know About IDR Frames but Were Afraid to Ask

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

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.

Cool Flash Widget at the Economist (How far behind is Mitt Romney?)

Sometimes I get so caught up in Flash video that I forget that Flash does many other things, from serving as the environment for the WeVideo editor to enabling sites like the Economist to present interactive data relating to the upcoming presidential...
