Don't Preview Encoded files in QuickTime Pro on Windows

I recently was producing some files for a client in Sorenson Squeeze, and saw some funky differences in exposure and contrast when previewing my work in QuickTime Player and other players. Click over to the main article to see a video that details what I saw.

Removing Echo from Audio with Adobe Audition

So, there I was, shooting a video for a Peer Review for StreamingMedia.com. If you're not familiar with these videos, it's where I critique videos presented by different web sites. While I simply don't have the production facilities to match the quality of some of the sites that I comment on, I do try to maximize the quality of my audio and video.

I was trying out a new microphone with the video segment, saw that levels were good, but didn't otherway pay attention to the quality. Then I got to editing the video (after putting away the lights, and storing all the audio gear, of course) and noticed a pretty severe echo in the audio.

Encoding H.264 Video for Streaming and Progressive Download - Presentation

Here's the description of the presentation that I just gave at StreamingMedia West. You can download the PDF below. Enjoy!

This seminar focuses on producing H.264 video  for streaming or progressive download. It starts with a deep look at key H.264 encoding parameters like B-frames, profiles, and levels and how to customize encoding parameters for distributing via QuickTime and Flash. After detailing how to operate the H.264-related encoding  parameters in tools from Adobe, Apple, Microsoft, Sorenson, and  Telestream, it then provides a brief overview of the respective quality output of these tools. Learn how your encoding tool compares in terms of quality and configurability, as well as how to configure  your encoding tool for maximum H.264 quality.

WebM vs. H.264 Bakeoff - Presentation and Handout

I just finished my H.264 vs. WebM Bakeoff presentation - you can download the PDF below.

You’ve heard the hype about VP8, but how does it really compare to H.264? This session compares quality, encoding speed, and playback requirements. It also details access to VP8 encoding from within live and on-demand encoding tools, the availability of hardware playback acceleration, and features like adaptive streaming. The session also reviews VP8 usage by YouTube and other websites.

Microsoft Throws Silverlight Under the Bus

Microsoft Silverlight has been very noticably used by NBC (Olympics/Sunday Night Football), but never achieved the penetration necessary for smaller businesses to adopt it. The thing is, while the sizzle behind Silverlight has always been video (as with Flash), the steak has always been Rich Internet Applications, and more specifically, the tools that developers use to build them. In my view, that's the primary reason that Silverlight exists.

Now, Microsoft is de-emphasizing Silverlight in favor of HTML5. This will have very little impact in the streaming video marketplace, but you don't need C#, .NET or Visual Basic to build HTML5 apps. So where does that leave developers?
