Another Ogg to H.264 comparison

I recently posted an H.264 vs. Ogg comparison, which you can see here. http://www.streaminglearningcenter.com/articles/ogg-vs-h264---round-one.html I got lots of good feedback and am in the process of reworking my tests, primarily (I hope) to use a m...

Flash Player: CPU Hog or Hot Tamale? It Depends.

ipad.jpgIn part, Steve Jobs stated that the iPad didn't support Flash because it was a "CPU Hog," so Apple used a technology called HTML5 instead. Since the comparative efficiency of Flash vs. HTML5 seemed easy enough to quantify, I endeavored to do so, using YouTube's new HTML5-based player as the test bed. Specifically, I played a YouTube video in the same browser twice, once via HTML5, once via Flash, and measured CPU utilization during playback.

The results? Decidely bi-polar. You can probably guess which pole was colder.

Updated findings below.

Ogg Theora and HTML5 have been top of mind for me over the last few weeks, and one consistent question was how Ogg compared to H.264 in terms of quality. So, I spent a few hours this past weekend encoding and comparing. Click through to the main article to see what I found. 

Reclaim disc space from Premiere Pro

I do a lot of production work and testing on my HP Z800 workstation. Though it's got a 250 GB C:\ drive, with a 1 TB video drive where I store all projects and associated video, I started getting messages that I was running out of space on my C:\ dri...

The Future of Web Video

HTML5? Someday. Ogg? Probably not.

I admit that the nexus is a bit tenuous, but if you're an Apple Final Cut Pro producer, you're undoubtedly producing for the Web. Over the past few months, you've been hearing that Flash is going away, H.264 is going away, and soon you'll have to produce all your video in an open-source video codec called Ogg Theora (of all things). Well I'm here to tell you why that won't happen, so you can push away all those scary, vicious rumors and go back to what you do all day.

This is a two-part article. Page 1 will take a look at HTML5 and what it can and can't do, and page 2 will focus on the future of Ogg Theora.
