Step One: Preparing Your Image

To begin, open the Snagit Editor and create a new image. Make sure to create the image the same width as your video. For example, if you want your video size to be 1280×720 then the width of your image should be 1280 pixels.

The dimensions for your video might be different based on the size of your video. If you have a long problem you will have to make your image long enough to include room to solve the entire problem. In this example, the image is 1280×2160, which should leave plenty of room to solve the problem. You may have to experiment with your handwriting and the length of the image a little to see what will work for you. Choose the Canvas colors that you want as the backdrop for your problem and click ok.

On the View tab, make sure your image is displayed at 100%. Drag the editor window until you can see the entire width of your image without scrolling. You will need the whole width showing to make a video that has the width of your image.  Make sure your image has at least enough pixels showing to fill up the height of your video. This image shows how the recorder will look on your image when recording.

Step 2: Adjust Settings

There is a setting you will need to enable so the Snagit Editor does not minimize when you start your capture. In the Snagit Capture window, go to Tools > Program Preferences.

Click on the Program Options tab and uncheck Hide Snagit before capturing. In the bottom right corner of the capture window change the capture type to video and note your capture hotkey—the default is Print Screen.

Now return to the Snagit Editor. On the Draw tab select the pen tool and choose one of the preset writing styles or choose your own by adjusting the properties in the outline menu.

Step 3: Recording

Before you record your video, make sure to practice working through your problem a couple of times so you can get the best recording possible. Now press the capture hotkey (Print Screen) to start your video capture. The crosshairs will appear.

Use the magnifier to select the upper right-hand corner of your capture and drag to the exact size of your video in the lower left-hand corner, which in this case is 1280×720.

The recording interface will display. Make sure that you are getting sound through your microphone, indicated by the green bars next to the microphone button. When you are ready to start click the record button, you will get a recording countdown, and recording will begin.Start solving your math problem using the pen tool and your mouse, explaining your process as you go. If you prefer, a tablet can help make writing easier. If your problem is long you can scroll your image up to give you more space by holding Ctrl+Shift while clicking and dragging with your mouse. When you are done solving your problem, press the stop button or Shift+F10, and your video will appear in the Snagit Editor.

Step 4: Save and Share

In the Snagit Editor you can review your video, save individual frames as images, or save your video as an MP4. If you want to share your video, go to the Share tab and send it to Screencast.com or YouTube.
