Perian, the "Swiss Army knife for QuickTime," has decided to cease development after six years on the market. The Perian team posted a notice to its users this week, saying that the software is "as complete as it will ever be under our stewardship." Though we can't disagree with the team's reason for wanting to move on, Perian's retirement is a bittersweet reminder of the earlier days of Apple, when watching videos of different codecs was a challenge on the Mac.

If you're using Picasa you don't need to read any further, as I'm sure you already know this.  If you're not using Picasa for any reason, let me tell you one of the main reasons I do.   As you probably know Picasa is a pretty handy little free program for editing, managing and sharing your photos, but I rarely use it for any of those things.  What I love most about Picasa is the included Picasa Photo Viewer application.

A series of Key frames (K) and Delta frames from a video stream.

Lossless trimming is the ability to trim, cut or extract segments of audio & video without re-encoding the original multimedia streams, maintaining both the original frames/samples and their related metadata. It is a process as old as digital video itself, and one that can be extremely helpful when dealing with hundreds or thousands of hours of digital video evidence for a case.

Reduce file size, reduce duration and maintain the original frames & quality. Bonus, the process is even faster than traditional editing, as you don't have to wait for the video to be re-encoded!

Spatial vs. Temporal Compression

Spatial (Intraframe) compression is applied to each video frame independently, treating each frame as a stand-alone image. This is the type of compression leveraged by high-end video production facilities as it provides superior picture quality and efficiencies in the editing process. Every frame is a key frame.

Earlier today I deployed a new Members-Only chat system for our professional community members. Once a member logs in they'll find a small chat bar in the lower right-hand corner of their browser. Now members can immediately know who's online, chat one-on-one with them, or even invite members to a group chat by simply clicking the invite button next to their name. Do you use Skype? Great, click the chat settings icon (gear icon) and enter your Skype ID; now members can quickly click-to-call you via Skype video too!

Like all DME Resources content, Members-Only chat is served via a minimum of a 128-bit encrypted connection; 256-bit in many cases. For those occasions when you're not feeling very social, you can click the settings icon and deactivate the chat feature. Give it a go and let me know your thoughts. As always, thanks for your participation!
