A lot of us have to compress video for PowerPoint, and what we want is really embeded in PowerPoint and working cross platform. For that to be the case, it's got to be an MPEG-4 file. And what we are going to do is we are going to use our starting point. We are going to build a custom MPEG-4 file, and I am going to show you a couple of the ways you can vary that. But we are going to build it for PowerPoint, ready to go and ready to be embedded. Because in the Mac we are guaranteed to have QuickTime, while in the PC we are not, but we want to make sure that Windows Media Player can play it, and that's why we are picking an MPEG-4 file.
So I am going to take our Mission Starting Point. Again, I will say to you, you can use any video you want, or start in Final Cut Pro. And I am going to build a video from scratch here. So I'm going to pick the MPEG-4 type. And it's untitled. We will eventually save it and call it PowerPoint, or we will do it MP4 for Powerpoint. I will fill in the Description later, but let's start walking through this. Here under the MPEG-4 tab of the Encoder, I definitely am going to want to pick the main profile.
This gives me a much better and much more robust algorithm for compression. I am going to let it dictate its own Frame Rate and Key Frame Interval. This will match the video as best as possible. I'm definitely going to tell it to do an analyzation pass separate from the compression pass, so I will pick Multi-pass. And I am going to take this Bit Rate and just drag it all the way out to the right. 10,000 is a great number. This is a huge data rate. This will work for high def or standard def. It's just a nice healthy area for your video to breathe in. I am not going to make any changes to the audio.
And even though when I come over to Streaming, it's enabled, it really doesn't make a difference if this is on or not. You know what? Since we are not really streaming this, I am going to turn it off. So I'm happy with the encoding. The only question is, is how big is what you are going to produce? How big do you want it to show up? Very rarely will you be on a high- def projector doing something out of high def in PowerPoint. And it may not hurt your movie for you to cut the size so it fits on a slide itself. To do this, I am going to go over to the Frame Controls tab, the Geometry tab, and on the Geometry tab here, I am going to pick for the Frame Size 50% of source.
Now, the beauty of it being 50% of source is it doesn't make a difference whether you're working in high def at 1080 or 720, it's going to make it a quarter of the size, 50% of the height, 50% of the width yields a quarter of the size. You don't have to do this. This is kind of a nice bonus. This is going to make the video smaller and make it definitely fit on screen, versus having to do some sort of adaptive downsampling while playing back. If you are on a high-def projector, you can feel free to not do this step, but this I like as a nice step. And I am going to go ahead 50p scale, just to leave me with that extra piece of information, at 10mbs.
As much as possible, whenever you are changing these rates here, I really encourage you to make that as part of the name. And as a Description, I am going to say Perfect for embedding in PP, and this of course is a modern day PowerPoint. This is not the older one. This is, I would say, 2010 and after versions of Microsoft Office. I am going to go ahead and hit Save. I want to take this one I have just built, I'm going to drag it into my video, I am going to tell it to go ahead and Submit, and it's going to compress my video, ready for me to go and drag into a PowerPoint slide.
Now that it's compressed, I can go ahead and switch out to the Finder. You can see I have got this gorgeous MPEG-4 file. This works cross platform on Windows 7, OS X--that would be Snow Leopard and Lion. It probably works in 10.4, but I'm not 100% sure. But the beauty is, because it's an MPEG-4 file on the Mac, it's handled by QuickTime; on a PC, it's handled by Windows Media Player. Either way it works embedded into PowerPoint, which is the whole reason we built an MPEG-4.
