Excerpt/Capsule: Learn about the Correction adjustment options for videos in PowerPoint 2010.
When you insert a video clip on your slide in PowerPoint 2010, you might find out that the clip is too dark or light in terms of appearance. This is similar to what you may see on your television, especially a new television where you have to make a few adjustments to get the picture just right. Similar corrections can be made to any of the video clips you insert within your PowerPoint slides. These kind of adjustments may be not only necessary for the appearance of the video clips on your computer, but also for how they show when projected onto a screen or even on a connected TV. Projectors are typically not as bright as computer screens, and some adjustments may help. The other reason to make any video clip light or dark through corrections is so that it can compensate for problems with the original video clip. Let us learn how to make corrections to the inserted video clip in terms of brightness and contrast:
- 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 you will not see any live preview of the actual correction adjustments you make. This is 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.
Figure 2: Video clip with a poster frame added - Now, within the Video Tools Format tab, locate the Adjust group and click the Corrections button (highlighted in red, within Figure 3) to access the Corrections drop-down gallery that you can see in Figure 3.

The Corrections gallery displays the preview thumbnails with different brightness and contrast values. The thumbnail in the middle (highlighted in yellow) represents the current status of the video.
- Hover your mouse cursor over any of the brightness and contrast variants within the Corrections drop-down gallery. As you hover, you will see a tool tip, as shown in Figure 4, which displays the adjustment values of the particular variant. In addition, you will also see how the change affects the actual video clip's frame.

- At this point, if you are happy with the correction, you are done. Otherwise, you can further fine-tune the correction. To do that, select the Video Corrections Options (highlighted in red within Figure 4, above) to summon the Format Video dialog box. In this dialog box, make sure that the Video option is selected in the sidebar as you can see in Figure 5, below. Note that in Figure 5, the options that are not related to Corrections have been grayed out.

Options related to Correction adjustments are explained below, as marked in Figure 5 above:
- Presets: Clicking the Preset button brings up a drop-down gallery, as shown in Figure 6. This gallery is same as the Corrections drop-down gallery shown in Figure 4, above. Here, you can select any of the preset Correction variants.

- Brightness: Use the Brightness slider which you can find right below the Presets button (refer to Figure 5, above) to change the brightness level of the video clip. Moving the slider towards left makes the video clip duller and moving it towards right makes the color brighter. You also have an option of directly entering the exact brightness percentage you want within the box next to the Brightness slider. Use the up and down arrows within the box to increase or decrease the brightness percentage value as required.
- Contrast: Use the Contrast slider (refer to Figure 5, above) to change the contrast level of the video clip. You can also directly type in the contrast percentage within the box next to the Contrast slider and use the up and down arrows within the box to increase or decrease the contrast percentage value as required.
- Reset: If you want to abandon all changes made to the video clip within the Brightness and Contrast (and Recolor) area, click the Reset button. Note that when you click this button, the video will be reset to its original form.
Once you have fine-tuned the video using the Correction options within the Format Video dialog box, click the Close button to apply the changes and get back to the slide.
- Presets: Clicking the Preset button brings up a drop-down gallery, as shown in Figure 6. This gallery is same as the Corrections drop-down gallery shown in Figure 4, above. Here, you can select any of the preset Correction variants.
- Figure 7 shows the selected video clip with changed brightness and contrast values. Compare Figures 1 and 7 to see the difference.
