Once you insert a video into your presentation, you'll want to specify its size on the slide. Here are several different techniques you can use. I'm going to go to slide six in my presentation. Notice, I have a place for my video but no placeholder. If I was using a placeholder, my video would resize itself to fit the given space. If I insert a video cleanly into a slide however, the video will come in at its original size. I'll go up to the Insert tab and then to the far right to the Video button and I'll insert welcome_3s.
When I first insert the video onto my slide, it's so large that it covers up my slide title. The simplest way to resize your video is to use the handles in the corners. When you hold your cursor over one of the dots, it will turn into a double headed arrow. Click and drag and your video will become smaller or larger. If you need your video to be larger, you may get mixed results, depending on how the media asset was encoded. You may find that the image loses resolution and gets fuzzy. In that case, there's nothing you can do from inside PowerPoint.
You'll need to go back to your original footage and export it at a larger size. Going smaller though will never be an issue. Now, don't use the side handles or the top and bottom handles when resizing your video. You'll lose your proportions and your imagery will come in short and fat, or tall and skinny. I'm going to undo that resize. If you want to specify the exact dimensions of your video, click on your video and go up to the Video Tools Format Ribbon and on the far right-hand side there's control for Height and Width. You can type values into the box, or you can use the spinner arrows to increase or decrease the dimensions in .1 increments.
Notice that as I adjust the height, the width changes too and if I adjust the width, the height changes. One thing to note when adjusting your size is that PowerPoint's compression utility requires that both the height and the width be divisible by 4. If you will be compressing your media asset to the end of your project, keep this in mind as you set your dimensions. For even more control, click on the little launcher arrow in the bottom right corner of the size group. Adialogue box opens and I can see that I'm in the Size section, if needed, drag on the bar at the top to move it so it doesn't cover your video.
In addition to the same Height and Width boxes, I also have Rotation. Click on it and you can see your video tilt. Up will tilt it clockwise, and down will tilt it counterclockwise. I'll return it to zero. Scale works exactly like height and width but instead of showing its actual dimensions, you can see how its current size compares to its original size as expressed in the percentage. This Lock aspect ratio checkbox causes the media clip to stay proportional so that the height and width adjust in tandem.
If you want to adjust one but not the other, uncheck this box. If this box is unchecked though, you run the risk of distorting your video image so it's usually best to leave it on. If you uncheck Relative to original picture size, after you change the dimensions and leave this dialogue box, your new settings will become the new 100% instead of staying at 82%. In other words, every change you make becomes the clip's new default size. The drawback to using this setting is that once an image is sized at a hundred percent, making it larger may reduce your clip's clarity.
If you're less concerned with the clip's size in inches, because after all your slideshow is multimedia and not printed on paper, you can use Best Scale for slideshow and choose your screen resolution from the dropdown list. Your video will resize itself to the appropriate resolution but note that your choice here must match your actual screen resolution, otherwise your video will become distorted. I'm going to turn it off again. Note at the bottom of this dialogue box, you can see the original dimensions of the clip before you started adjusting it. If you don't like what you did, you can always click this Reset button to put it back to its initial default size and then start over again.
Once you have your size how you would like it, click the Close button at the bottom and your changes are saved. Here are few more ways of getting your size adjustments. Notice that while I'm clicked on my movie because I've been in the size box, I now have a green rotate handle that I can use to spin my video around. If I right click on the video clip, the Height and the Width are available right in this little pop-up. You can also choose Size and Position off the short-cut menu and it goes right to the dialogue box we just explored. Adjusting the size of a video clip is extremely easy to do and between the object handles, the Ribbon, and the dialogue box, PowerPoint allows you to set your size with just the level of complexity you need.
