The movies you find in the Online Training Library are available in multiple formats, giving you the ability to choose the video player type that best suits your needs. While signed in to your account, go to my account > site preferences to view and select the video player of your choice. The choices of Flash, QuickTime Standard, and QuickTime Custom are available on both the Mac and Windows operating systems. If you're on Windows, as I am here, you will have the additional choice of Windows Media. Now, your choice of player may boil down to simply wanting to select a player that's native to your operating system and doesn't require you to install any additional plug-ins. For instance, if you are on Windows, you will have to download and install the Adobe Flash and Apple QuickTime plug- ins from their respective sites, get that adobe.com/flashplayer and apple.com/ quicktime in order to view videos in those formats. But if you choose Windows Media, you'll be able to play our videos without any additional plug-ins. Similarly, if you're on a Mac you will be able to select either QuickTime format, but you'll need to download the Flash plug-in. These days though, it's probably unlikely you don't have the Flash plug-in installed, regardless of what platform you're on. So you should also take a look at this table. Notice each player type has certain features unique to itself, as well as features shared with some or all of the other players. For example, all of the players support closed captioning. QuickTime Standard is the only player that doesn't support adding bookmarks from within the player window, and it's also the only one that's not compatible with 64-bit operating systems. QuickTime custom and Windows media are the only two that allow you to adjust the speed of playback, and Flash is the only plug-in that allows you to increase the size of a video. So I currently have QuickTime standard selected, but its features are pretty limited when compared to the other players, so I am going to select QuickTime Custom. And I am going to click Save, and you can see I have the message here that my player preferences have been updated to QuickTime Custom. And now if I go back to a course-- I will just go to our homepage here and click on a course--and if I start a movie playing-- (Male Speaker: The palettes in AutoCad give us access to a lot of functionality.) I'll just pause that for a second here, but now I see the QuickTime custom interface. Here you can see the speed controls. If I want to speed up the playback, I can just speed I can just speed that up to two times. (Male Speaker: However, they take up a lot of space too. Or I can slow it down. (Male Speaker: Using a single monitor, it doesn't take long before your palettes completely take over your--) So speeding up the playback is a nice way to get through the movies a little more quickly. You can see over here are my bookmark buttons. I can bookmark the movie or timecode directly from right here in the movie player. We will talk more about bookmarks later. Now, if you change your mind about which player you want to use, or if you find yourself having trouble loading movies with a certain player, you can always try another player. While on a course page, you can go to the Preferences tab, which is another way to access your site-wide player preferences, and from here maybe I will select Flash and click Apply. Now, if you are not a member of the Online Training Library, or if you are but just aren't logged in, you can still access this Preferences tab to try out different player types. So now I want to go back to the table of contents and select another movie. (Male Speaker: When using AutoCad in production--) Now you can see the window looked similar at first glance-- I can add movie bookmarks or timecode bookmarks--but notice with the Flash player I don't have any speed controls. And also unlike the QuickTime custom player, I now have this maximize button here, which allows me to zoom my movie to full-screen size. Similarly, I can minimize to go back to the default size. So those in the various player types available to you, and how you go about setting your player preferences.
