When you insert a video clip within a PowerPoint slide, you'll
find it placed as a traditional rectangular shape. And while that's exactly what most users expect, it does seem safe and conventional. However,
PowerPoint 2010 does allow you to have your video playing in different shapes such as a circle or oval, or a wave, a triangle, or any of the shapes
that PowerPoint includes. Just the fact that a video can be placed within a shape is no reason to forego the conventional rectangle -- do remember
that most other shapes may crop out important parts of your video clips.
In the following tutorial, we will describe to you how you can constrain your video to play within a specific shape:
- Open your presentation, and navigate to the required slide where you have already
inserted a video clip. Just select or double-click the video clip to
bring up the two Video Tools tabs in the Ribbon. These two tabs
are Format and Playback -- click the Format tab to activate it, as shown in
Figure 1 (highlighted in red).

- When you insert a video your slide, it may display a black rectangle on the slide (see Figure 1, above). If your video clip does
not show a black rectangle, then directly proceed to Step 3.
If you see the black rectangle in place of the video clip, then the live
preview you see will show a black fill within the actual shape applied to your video clip. This happens because you see a black rectangle instead
of a frame associated with the video clip. To make sure you see a video frame during live preview, add a
Poster Frame to your video clip -- that way you will see a
video frame in the place of black rectangle, as shown in Figure 2 below.

- Within the Video Tools Format tab, locate the Video Styles group and click the
Video Shapebutton (highlighted in blue within Figure 1, above) to access the Video Shape drop-down
gallery that you can see in Figure 3.

Note: The Video Shape drop-down gallery is similar to
Shapes
gallery in PowerPoint 2010.
- Now, select any shape from the Video Shape drop-down gallery that suits your requirements. For this tutorial, we have chosen the
Isosceles Triangle, as shown in Figure 3 above.
- This constrains the selected video within the Isosceles Triangle shape. Play your video at least once to ensure that no important parts get
cropped out. Figure 4 shows previously inserted video is now playing within the Isosceles Triangle.

Once the shape of the video is changed you can use the
Video Effects,
Video Border, or the
Video Styles to enhance its look.
Tip: Try using shapes that are similar to a conventional rectangle such as a Rounded Rectangle or any of the Snipped rectangles (see
Figure 5 below). This way you can prevent large areas of the video from being cropped out when a shape is added.

- Make sure you save your presentation.
