Seawell and the future of Scalable Video Coding

I’ve been tracking Scalable Video Coding (SVC) for the last year or so and there’s been little tangible evidence of adoption. Recently Toronto-based Seawell Networks came out of stealth mode, but only barely, announcing that they are in the H.264 marketplace, but providing no product details. I met company CEO Brian Collie at a trade show last November, but he …

Ogg, MPEG-LA and Submarine Patents

A few weeks ago, I published an interview with MPEG LA CEO Larry Horn on the patent group’s decision not to charge for free content encoded with H.264. Then I got a note back from a reader who stated: I’m disappointed. The interview seemed to be pretty powder puff. Why not ask the harder questions, e.g., was your decision in …

If you’re encoding in QuickTime/Compressor, you gotta checkout x264

So, I was doing some consulting work for a client who’s currently encoding with the x264 codec. Part of the work involved benchmarking their current quality against other encoding tools I have around the office, so I downloaded the x264 QuickTime Codec (Mac) from Softonic, which was the tool used by the client.

Another Ogg to H.264 comparison

I recently posted an H.264 vs. Ogg comparison, which you can see here. Ogg vs H264 – Round One I got lots of good feedback and am in the process of reworking my tests, primarily (I hope) to use a more recent codebase that wasn’t shipping when I did my testing. In the meantime, another comparison was released on February …

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: drive. I couldn’t imagine why since I store all the …

HTML5, Flash, H.264 and Ogg Theora

Ever since the iPad announcement, the inter-relationships between HTML5, Flash, H.264 and Ogg Theora have been intriguing me, so I spent last week trying to figure it all out. The result is The Future of Web Video, Part 1; HTML5? Someday. Ogg? Probably not, over at the Digital Content Producer web site. It’s an article that’s bound to irritate lots …

An essential gizmo for Mac video producers

This is not an earthshaking post, but I thought I would share it anyway. I’ve never been a fan of Apple’s decision to use FireWire 800 adapters on their most recent lines of computers since it meant that I couldn’t connect my camcorders to them without an adapter. I’ve resisted purchasing a FireWire 800 to 400 adapter because I have …
