For capturing screenshots or video of Mac screens, Sequence takes advantage of multithreaded code and 64-bit support for compression. Capturing DVD playback and audio is easy, and it's possible to record from your iSight and screen at the same time. With the voice recording function, you can narrate the screen capture for easy creation of screencasts.

Documentation for Sequence is now built into the application, which can be used to develop training videos, product demos, tutorials, and archiving streaming video. Mac OS X 10.5 or later is required.

Sequence is available from App4Mac for $29. Localized versions are available in French and simplified Chinese.

Last week, Dave mentioned that you can change the file type used system-wide for screenshots. However, some people are afraid of using Terminal.app to muck around with their Mac. In this week's AppleScript article, I am going to show you how to take screenshots and change their file type using an AppleScript.

The AppleScript
property N : 0
set N to N + 1
set picPath to ((POSIX path of (path to desktop)) & "Picture_" & N & ".png") as string
do shell script "screencapture -tjpg " & quoted form of picPath


Using the AppleScript
Open the ScriptEditor (/Applications/AppleScript/ScriptEditor.app). Copy/paste the AppleScript into the script edtitor and click the run button at the top. You will hear the camera shutter sound and a picture will be taken and saved to your desktop.

This script comes in handy when you want to take a screenshot in a different format. To do this, just change the ".png" file type to whatever you might want (say, .jpg, .tiff, etc.). When you re-run the script, the new file type will be associated with the capture image.

Whether you want to post something to a web page or blog, or show off an application element in a presentation, taking quality screenshots is becoming an increasingly common task for lots of different Mac users. Although OS X comes with its own built-in screenshot utility, Grab, and onboard F-keys for the task, there are lots of third-party options as well. Contrary to popular belief, not all screen capture applications are created equal.

So what program is the best for taking quality screenshots off of your computer? To find out, I put five screen capture programs through their paces to try to find the "ultimate" screen-capture program.

The programs I used:

• Grab - built into OS X
• Skitch - free (at least while in beta)
• Snapz Pro X - $29 for image capture only, $69 for image and motion capture
• InstantShot! - free
• QuickSnap - $14.95

Read-on for my analysis and take a look at the gallery for screenshots from each program, as well as head-to-head comparisons.

Screencasting is becoming a standard method of conveying software-related information. I'm fairly certain that even my mom knows the word, which is my typical buzz-guage. And here you were, thinking "I wish there was yet another contender in the screencast recording arena", right? Lucky you.

Synium's Screenium, which is currently in beta preview, is a new arrival in an already teeming category of software. It has standard features like fullscreen, fixed area and mouse-follow capture, hotkey integration and adjustable quality/frame rate with capture presets. It also boasts a single window capture mode and frame rates up to 60fps. I don't know why you'd need to capture a screen at 60fps, but it can't hurt to know it's available.

In my testing, Screenium performed exceptionally well in the area of small filesize, high quality captures and its default presets were simple and useful. It also gets high marks for ease of use. And it didn't max out my CPU and turn my fans into Harrier jets after 2 minutes, which is kind of nice when you're recording microphone audio. It's got some distance to cover before the official release in February, but Screenium is looking like a strong contender.

Earlier today, Ambrosia released version 2.1.1 of their popular screen capture tool (we've written about Snapz Pro X several times). For the unfamiliar: Snapz Pro X lets you capture what you're doing on your Mac's screen - or just a portion thereof - as a Quicktime movie. It's a fantastic way to make screencasts, and also snags audio and still images.

Version 2.1.1 brings a number of changes, including:

• Improved registration experience
• Several squashed bugs, including the blank frames at the end of some movies and garbled video capture on older, nVidia-equipped Macs
• Improved performance for audio captures

We like Snapz Pro X quite a bit. Try it out.

A single license will cost you $69US. It's universal and requires Mac OS 10.3.9 or later.

Everyone got a #2 pencil? Then we're ready for more Mac 101, tips and tricks for novices and "I forgot how to do that!" veterans alike. Today we're talking screenshots, an essential tool whenever you need to document or display something for posterity. While there are lots of third-party tools for screenshot capture, the basic functions included with Mac OS X are nothing to sneeze at.

The original, held-over-from-Classic method for screen capture is the venerable keyboard shortcut (sometimes referred to as an 'F-key'), Command-Shift-3. Hitting this key combo creates a 'Picture 1.jpg' (or .png, .pdf or .tiff file, depending on your OS version and whether you've fiddled with your settings via Terminal or AppleScript utility) that includes your entire desktop, multiple displays and all. Too much of a good thing? Try Command-Shift-4, and drag the crosshairs over the target area (hit Spacebar to toggle a 'camera' icon that will capture a full window with a click; hit Esc to get out of capture mode). As you use these keys, and a collection of 'Picture N.jpg' files begins to accumulate on your desktop, try adding the Control key to the combo -- Ctrl-Cmd-Shift-3/4 sends the captured image to the Clipboard, rather than a file. Personally, I use the clipboard version of the 4 key all the time to copy snippets of my iPhoto images into outgoing mail. It's faster & easier than exporting the full-size image.

Sometimes, unfortunately, a command key is not quite good enough; for example, it's tricky to capture a pull-down menu onscreen. For this, there is Apple's Grab application, hiding out in your Utilities folder (also available as a Service in many applications). In addition to basic capture acrobatics, Grab offers a Timed Capture tool that works exactly like the timer button on a camera: hit the Capture menu/Timed Screen (or Command-Shift-Z), start the timer, get your ducks in a row and wait ten seconds. You can even Cmd-Shift-4 the resulting full-screen image to snag a small section if that's what you need. Happy snapping!

It's always something: just as I start to write up a Mac 101 on screen grabbing, along comes something cool, free and pretty: Jing for Mac. Built by the screen capture savants at TechSmith (developers of Windows tools Camtasia and SnagIt), Jing combines a lightweight, one-click image or motion capture tool with a free 200 MB hosting account at Screencast.com. The result is a fine way to quickly get 'casual' captures online and shared with a minimum of fuss. The motion captures are saved as .swf Flash video, which is either a bonus or a drawback depending on your perspective.

The current-but-one version (labeled a 'project,' not a beta) gave me a smidge of trouble on a dual-monitor setup, but the current 1.2.4 version seems to be working better, and it also cleared up a conflict with Growl. I'll do a few captures here and get a gallery together to see how they look. Jing isn't going to replace power tools like Snapz Pro, ImageWell or Skitch, but it's pretty good at what it does. Also, as Laurie pointed out, the Jing installer comes with a handy 'autoinstall' AppleScript that copies the application and then unmounts the disk image -- particularly useful for those friends and family (you know who they are) that seem to get confused and end up running applications from a mounted .dmg instead of installing them properly.

Thanks Laurie & Dave

Here we go with another edition of TUAW Desktops ladies and gents. You readers are submitting some great stuff to our desktops Flickr group, and since our last edition was a nice overall roundup, I decided to pick a theme for this week: function. I'm a big fan of making the most out of my available desktop real estate, and the desktops I've chosen each exhibit an interesting perspective on this practice. In this edition we have desktops ranging from über-minimal yet uniquely-functional to a full-on Exposé overload, and even a pseudo-multi-dock environment. But without further adieu, let's get down to business:


First up is shorts by pacificbro. By his own admission this isn't so much a clever, intricate desktop setup, though it's more of a functional use of the wallpaper space with many common (and some not-so) keyboard shortcuts he needs to get around his daily business. Too bad I didn't see this before the My Dream App stuff started - I just got inspired to submit an app idea that swaps out shortcuts like this on the desktop space depending on what app you're currently working in. A simple F11 Exposé keystroke would reveal all (or most) of the shortcuts you need to work. *Sigh* - maybe I can get in on round two. But speaking of Exposé, let's keep moving.

Just like its title implies, Screenshot Settings 1.1 is a simple little GUI applescript that allows you to change both the image format Mac OS X uses to capture screenshots, as well as the default location where these images are stored.

While altering Mac OS X's screenshot format is pretty simple with this little utility (see: this post's screenshot), the trick to choosing a new default location for storing screenshots is a little less obvious: simply drag the new location from Finder onto the utility to set it as the screenshot hotspot for your Mac.
