In Encore CS5 Essential Training, author Chad Perkins gives an extensive overview of Encore CS5, Adobe's powerful application for authoring DVDs, Blu-ray Discs, and Flash-based video for the web. This course covers adding audio and subtitle tracks, creating image slideshows, and using Encore as a presentation tool. Also explained are the Blu-ray enhancements in CS5, and advanced techniques such as creating games and hidden content for disc menus. Exercise files are included with the course.
In this movie, we're going to look at what a Blu-ray disc is. For this, we'll be using the New Project dialog box, which you can find by going to File > New Project. The Authoring mode we have been using most of the time in this training series has been DVD. What I want you to do is click on Blu-ray. Again, Blu-ray is a high-definition disc format. And it's great because it's high- definition, and it's really big. So you can fit way more stuff on there, and the quality is way better. One of the good things and one of the bad things about Blu-ray is that there are so many choices.
So what I would like you to do is select Blu-ray as the Authoring mode and then click on Default Transcode Settings. Once we do that, then we'll see all of the options available to us when we're authoring Blu-ray discs. First of all, we look at the Maximum Audio/Video Bitrate. The minimum is 15 bits per second, which is a really high-quality video stream, and this is better than what we typically create with DVDs. Even the minimum Blu-ray is better than the best DVD. And it goes all the way up to 40 megabits per second.
If we go over to DVDs, you can see that this only goes up to 9.4 at its highest. So again, the quality here is unparalleled, and it really needs to be for such a huge output. Codec, this is interesting. When you are creating a DVD, you have to use MPEG-2 video. Well, Blu-ray started out as only having MPEG-2 video, and then about a year after it was released, decided to include H.264 video in its specs as well. Now, H.264 video, it's going to make it so it's not quite as compatible with those people that adopted Blu-ray early on.
It got those Blu-ray players the first year it came out or so. But H.264 delivers about the same quality as MPEG-2 at about half the size. That means you could fit about twice as much content with H.264 on a Blu-ray disc as you can with MPEG-2. But again, slightly less compatible, so keep that in mind. Now, the Dimensions are another slightly confusing thing. We can create a Blu-ray disc that's 720 x 480. That's SD or standard- definition, just like a DVD is.
But then three is multiple HD sizes, 1280 x 720, 1440 x 1080, and also full HD, which is 1920 x 1080. We also have many choices in Frame Rates: 23.976 for film, also 24 for film 29.97 is the standard Frame Rate for video, and then HD video. especially if you want a really clear, sharp picture, like good for sporting events and things like that, 59.94 frames per second. Another thing that we'll see that's kind of fun with Blu-ray discs is that there are special features, weird things that Blu-ray discs can do that DVDs cannot do.
The one that we're going to look at in the next movie is called a pop-up menu.
