Once you insert a video in your PowerPoint slide, you can crop it in almost the same way you crop a picture. Before you crop though, you must ascertain whether PowerPoint's Crop option will help create a better result for your inserted video. The Crop option allows you to remove non-required areas of a video. For example, if the subject of your video is a person speaking who is surrounded by a large, distracting background of other people or moving objects, you may want to crop the video so that the cropped video now focuses more on the speaker, and gets rid of all the extra distractions.
Note that cropping a video does not trim the timings of the video playback in any way. In fact, trimming is a completely different option that will be explored in another tutorial.
In the following tutorial, we will explore how you can crop a video clip in PowerPoint 2010 for Windows:
- Open your presentation, and navigate to the required slide where you have already inserted a video clip. 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 highlighted in red within Figure 1, below.

- The Video Tools Format tab is a Contextual tab. Contextual tabs are special tabs in the Ribbon that are not visible all the time. They only make an appearance when you are working with a particular slide object which can be edited using special options.
- When you insert a video on your slide, it may display a black rectangle on the slide, as shown in 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 you will not see any Live Preview of the cropping you apply. This is because you see a black rectangle instead of a frame associated with the video clip. To make sure you see this live preview, add a Poster Frame to your video clip so that you see a proper video frame rather than the black rectangle, as shown in Figure 2, below.

- Now, within the Video Tools Format tab, locate the Size group and click the Crop button, as shown highlighted in red within Figure 3, below.

- Doing so brings up dark crop handles on the edges of the video clip, or on the edge of the shape if you have used the Video Shape option, as shown in Figure 4, below.

- Notice that there are eight handles. You will find four side cropping handles that look like straight lines, and also four corner cropping handles that look like slightly rotated Ls.
- You can alter how you crop by pressing the Ctrl key while you drag:
- To crop from one side of the video clip, drag the side cropping handle on that side inwards. For example, dragging the side cropping handle inwards from the left edge will crop out areas on the left part of the video clip.
- To crop from one corner of the video clip, drag the corner cropping handle on that corner inwards. For example, dragging the corner cropping handle inwards from the top-left will crop out areas on both the top and left parts of the video clip. You can alter how you crop by pressing the Ctrl key while you drag:
- Ctrl + dragging the side cropping handles will resize two opposite sides.
- Ctrl +dragging the corner cropping handles will resize all four sides.
- Shift + dragging the side cropping handles will provide no extra benefits.
- Shift + dragging the corner cropping handles will resize the video clip proportionately, retaining its height:width ratio
