Capture Options

Let us move on to your Capture Options , which will help give you a finer level of control over exactly how the capture is executed. Here we have a number of check boxes:

• Minimize before starting capture. Checking this option gets the Camtasia Recorder window out of your way when recording is engaged and brings the window back when the recording is paused or stopped . This will ensure that you don’t inadvertently capture the Recorder window instead of the desired application. This setting is on by default.

• Pause before starting capture. Picture this: When starting your screen capture, the capture rectangle appears and recording begins. The problem is, the capture rectangle is a different size or in a different position than expected, and capture is effectively ruined before it has even begun. Pausing before starting capture circumvents this issue by starting the Recorder in paused mode when activating the capture. That way, you can tell ahead of time if the capture rectangle will encompass all the elements you want recorded and, just as importantly, make sure that no unwanted items get caught inside the rectangle. Also, if the location of the capture window needs adjusting, you can do so before recording begins by clicking and dragging one of the rectangle’s corner angle handles. This setting is off by default, but I personally always keep it enabled. It lets me do one final sanity check before I start my session.

• Hide capture rectangle. Normally, the capture rectangle is visible during record and paused modes (solid green when paused; blinking green and black while recording). When this option is enabled, the capture rectangle is invisible. In fact, the only visible indication that you’re recording is the Camtasia Recorder icon in your system tray, which blinks red and green during capture. Only when paused is the capture rectangle visible (in solid green). Why would you want to turn off such a helpful visual indicator like the capture rectangle? Well, you may find that even the corner handles of the capture rectangle get in the way of desktop elements, and it’s nice to make them invisible for an unobstructed view. You may also find the incessant blinking an annoyance, especially on longer captures. And finally, some screenshot applications and other graphic applications can auto-select individual objects on the desk- top, and the capture rectangle can confuse the program, as it sees the capture rectangle and everything inside it as one large object. Hiding the capture rectangle will let you perform the capture while preserving this auto-select functionality. This option is off by default.

• Solid capture rectangle. This check box will change the capture rectangle into a solid rectangle rather than one with angles at each corner. That way, you can have a pixel-exact view of those elements that are included in the capture. If both Hide capture rectangle and Solid capture rectangle are checked, the capture rectangle will be invisible during recording and solid when paused. This option is off by default.

• Report dropped frames . This is a handy option that will help you monitor how well your system is coping with the capture, telling you in the Recorder’s Statistics and Properties area just how many frames the system couldn’t capture due to performance issues.

  

  According to these statistics, we haven’t dropped a single frame. Yea!

  For weaker systems, this is a good way to quickly tell if you’re getting in over your head in terms of your Recorder settings or the content you’re trying to capture. Obviously, if you choose to enable this option, don’t also check Minimize before starting capture, as the Recorder window needs to actually be visible during recording for it to be of any use. This option is off by default.

• Round frame size to a 4 pixel boundary. When compressing your videos, several video codecs (Microsoft Video 1, among others) require that all videos have horizontal and vertical pixel dimensions that are in multiples of four. The TechSmith Screen Capture Codec (TSCC) does not have this limitation. But even if you’re only ever planning on using TSCC for your captures (and good for you if you are; that’s exactly what you should be doing!), you may want to switch to a different codec when producing your final project, and it’s nice to have all your bases covered. Unless you absolutely need to have pixel-exact captures, this limitation shouldn’t trip you up very often - the heights and widths of every commonly used screen resolution just happen to all be divisible by four, anyway. This option is on by default.

• Capture layered windows . There are some translucent or irregularly shaped windows, such as the Office Assistant in Microsoft Office, that appear to “float” above the other windows, completely untethered to a standard rectangular window. It’s actually not far from the truth - these are called layered windows , as the content is actually rendered on a separate layer above the desktop action.

  

  Layered windows such as Mr. Clippit here can be readily captured when this option is checked.

  Checking this option will allow Camtasia Recorder to record both the desktop screen activity and this additional layer. With it, you can literally capture everything you see on your screen. So why not leave it on all the time? Well, capturing these additional layers can really take a toll on your system performance, and your maximum frame rate will definitely take a hit. If you’re not recording a video that features any layered windows, it’s best to keep this option off until you really need it. It is off by default.

• Show toolbar underneath capture rectangle during recording. By default, whenever you’re performing a screen recording that doesn’t consume the full screen, Camtasia Recorder places a small toolbar just below your capture rectangle that lets you quickly pause, resume, stop, etc. It you never use this toolbar, you can turn it off permanently by clearing this check box.

Performance Options

Finally, we come to Performance Options . As you can see, there’s really only one option: Disable display acceleration during capture . This option keeps your system from choking during recording. If you look in your Statistics and Properties area and see that your captured frame rate is only 3 or 4 fps when it should be 15, chances are you’re recording with display acceleration enabled. Disabling should bring your actual fps in line with the frame rate you specified.

Why does this make such a difference? When working with your computer, your system normally relies on your video card to assume the load in displaying images on your screen. Especially for processor- intensive programs like games , video, or CAD applications, your video hardware uses display acceleration, which optimizes all those little bits to efficiently travel from your system memory to your video memory. For just about every application except screen capture, this tends to speed things up considerably. However, for screen capture and screen recording applications like Camtasia Studio, the data needs to flow in the opposite direction, from video memory to system memory. Like a fish trying to swim upstream, the data flow of hardware acceleration actually works against the Camtasia Recorder doing its job. Following our “ river ” analogy, disabling your hardware acceleration calms these waters, giving the Recorder a much easier time of recording your screen data. In fact, disabling hardware acceleration is probably the single most important thing you can do to improve your maximum frame rate.

Note that checking this option disables the display acceleration only during the recording process (i.e., the program is either in record or paused mode). You will see the screen quickly and temporarily go black when first entering record mode, and again when stopping the recording. This is from the Camtasia Recorder turning the display acceleration off and then back on again when finished. If you’re doing multiple takes, this constant screen flashing can get old rather quickly. This is why I generally tend to turn off the display acceleration globally, which is a setting in Windows, and it affects all applications.

Here’s how to globally disable your display acceleration :

1. Choose Start , and then select Control Panel . Open the Display Properties dialog by double-clicking the Display icon.

2. Click the Settings tab. This is the tab that controls the screen resolution and color depth of your monitor. In the lower right-hand corner of the dialog, you will see the Advanced button. Give it a click.

3. Click the Troubleshoot tab. Under Hardware Acceleration, drag the slider from Full to None . Click OK .

4. At the end of your session, repeat steps 1 through 3, this time dragging the slider from None back to Full .
