If you just finished recording and watching your preview, saving the project will automatically open it in the Editor. This is where you will be making your changes, cutting out anything unnecessary and adding transitions. Before you can begin editing, you will be asked what dimensions you want the final product to be. You can choose presets from the dropdown menu. These presets will be labeled with what they are recommended for. Try to use one of the automatic dimensions. These are based off the initial recording dimensions, and are resized to keep the original proportions. Choosing one of these will help prevent the image from being squished or stretched. You can change your editing dimensions at any time by clicking the Dimensions button at the top of the preview pane. Chances are, no matter how prepared you were, there are a few errors in your presentation. Luckily, you can quickly remove these errors with just a few clicks. Note: If your audio and video are on separate tracks on the timeline, deleting a section from one will not remove it from the other. Use the timeline navigation tool to find exactly where you want top cut. Click the magnifying glass to zoom in on the timeline, allowing for more precise control. Click and drag the red tab at the top of the Timeline navigation tool. Drag the red tab to the end of the section that you want to cut. Press Space to play back just the part that you have selected. Click the Cut button (scissors icon) above the Timeline to remove the selection. If you scaled down your video dimensions, Camtasia will apply the SmartFocus effect to zoom and pan around your presentation to focus on the active element. It will attempt to put focus on the cursor and active window. You can see where SmartFocus was added automatically by looking for the icons in the Timeline. Click and drag a SmartFocus icon to move when the transition occurs. Click a SmartFocus icon and then click the Visual Properties button to edit exactly how the transition occurs. You can make the pan slower or faster, make the zoom more or less pronounced, or delete the SmartFocus transition entirely. You can remove all SmartFocus animations by right-clicking on one of the icons and selecting "Delete all visual animations on media". Callouts are visual aids that help draw the attention of the viewer to important aspects of your presentation. Callouts can be text or they can be symbols or highlights. You can also use callouts to blur out parts of the screen. Use the Timeline to navigate to the portion of your presentation that you want to add a callout to. Click the Callout button above the Timeline. Create your callout. You can use a variety of predesigned shapes, type your own text, or choose an animated callout. Click the "+Add callout" button to add it to your presentation. Move the callout around the presentation by dragging it around the preview pane. You can adjust the length of the callout from the Timeline.

One-sentence summary -- Open the project in the Camtasia Editor. Choose your video dimensions. Cut unwanted audio and video. Check that SmartFocus was applied correctly. Add callouts to your presentation.

Article: Partially erupted (also called impacted) wisdom teeth, as well as ones that grow crooked, greatly increase the risk of an infection. Impacted and crooked wisdom teeth can create little pockets of space underneath the pericoronal flap where bacteria collect and flourish. Common signs of an infected wisdom tooth include: considerable gum swelling, severe pain, mild fever, swollen lymph nodes in your neck and along the edge of your jaw, pus around the inflamed tissue, bad breath and an unpleasant taste in your mouth. The type of pain associated with an infected wisdom tooth is often a constant dull ache combined with infrequent sharp and shooting pains. Pus is a grayish-white color and made from white blood cells of the immune system. These specialized cells rush to the infection site to kill bacteria, then they die and form pus. Bad breath can also be caused by trapped and rotting food underneath pericoronal flaps. Even if your wisdom teeth grow in crooked and become impacted within your jaw bone, they may not cause pain and other noticeable symptoms; however, with some time (even just a few weeks), they often start to crowd other teeth and push them out of alignment. This "domino effect" can eventually affect your teeth that are visible when you smile, making them twisted or crooked looking. If you think your front teeth are suddenly getting crooked or twisted, compare your current smile to older photographs. If your wisdom teeth are pushing others too far out of place, your dentist may recommend you have them removed. Once wisdom teeth are removed (extracted), other crooked teeth can slowly become realigned again naturally after a few weeks or months. Although some short-term tolerable pain and inflammation is normal with erupting wisdom teeth, chronic (long-term) pain and swelling is not. Wisdom teeth that fully grow in above the gum line don't usually cause much pain or swelling beyond a few weeks. Severe pain and inflammation that lasts for more than a few weeks is more common with impacted wisdom teeth that remain in the jaw bone. Impacted wisdom teeth that lead to severe and/or chronic symptoms should be removed. People with small jaws and mouths are much more likely to have impacted wisdom teeth that cause significant pain and swelling. Although impacted wisdom teeth might not directly cause symptoms, they can promote decay in other teeth or surrounding gum tissue that can lead to long-term pain. Deciding when to go to the dentist depends on your pain tolerance and ability to be patient. As a general rule, if the pain keeps you from getting sleep (without medication) for more than three to five days, then it's best to get your teeth checked out.
Question: What is a summary of what this article is about?
Be on the alert for an infection. Check your front teeth for crookedness. Chronic pain and swelling is not normal.
