Join Richard Harrington for an in-depth discussion in this video Prepping a video file with QuickTime Pro, part of PowerPoint: Using Photos and Video Effectively for Great Presentations.
When you choose to insert video files into PowerPoint they may not be quite optimized or ready for use. There's a couple of ways to go about this, but it'll typically mean using another application. Let's open a movie into QuickTime. You may need to choose View > Fit to Screen to make it a bit smaller. If you drag the handles down below, you could adjust the duration of the movie, allowing you to remove parts of the movie that you don't want to use. When satisfied, choose Edit > Trim to Selection. This makes it easy to get a shorter movie.
Then simply choose File > Export. This allows you to save out the file. You'll notice several different presets here included. Let's start with the Apple TV preset and save that out. This'll make it an M4V file which is a high quality MPEG-4. Let's also save off an MPEG-4 manually, by choosing MPEG-4 from the pop up list, and then use the Options here to really control it. I'll make sure I choose the MP4 from the pop up, and I'll use an HD preset here, 1920 by 1080.
And adjust the frame rate to match using the current frame rate, but I could lower that if I want. Down here you could see what's happening with the movie and it gives you a good idea of what's going on. If you want to bump up the data rate I'd recommend it and so you can choose a higher quality here. Let's choose h.264. Make sure we stick with the 1080. And bump this up just a little bit to 500. I'll use my current frame rate and choose OK.
And now write the file. The higher data rate insures that the quality of the file stays nice and crisp, but you'll have to find a good balance. Now, over in PowerPoint we can insert those files. I choose Insert > Video from my PC. You'll see that files are getting created. Here's the M4V file. And here is the MPEG-4. And you could see them both in there with different file size. Let's choose that first one and choose Insert.
You see it's added. I could press play and it looks pretty good. Although you'll notice that the quality is definitely more compressed on that video. On the other hand, if we insert the video with the higher data rate, it should be a bit cleaner. And sure enough, the picture quality is definitely improved. So, find a balance that works for you, and look at the available presets and experiment. But video encoding is going to be trial and error as you first work with it. But in this case, it looks pretty good. And I was able to make a good movie using QuickTime Player Pro.
