Subtitles of the Movie

In the previous movie, I demonstrated techniques for rendering your work area to create preview files to facilitate the playback of your sequences here in the Program view. Now every time you render a preview, Premiere Pro CS3 creates files on your hard drive. These preview files contain the results of any effects of Premiere Pro processed during a preview. For example, in the last movie I had some effects that were rendered as well as some transitions between two clips. If you preview the same work area more than once without making any changes to your effects or transitions in this case here, then Premiere Pro will playback the existing preview files instead of processing the sequence again using the computer's processing power. In the same way preview files can save time when you export the final video program by using these processed effects that are already stored. You can specify the location where you want to store these effects by choosing Edit, Preferences, and then choose the Scratch Disks option down at the bottom. And notice here in the dialog you have a designation here for setting the location of your video previews as well as audio previews. Now the disk that you choose to store these preview files should be large and fast enough to support video playback, so choose a hard drive that's attached to your computer, not a network drive. Also, because Premiere Pro CS3 must be able to locate the preview files when you open a project, avoid specifying removable media. You may choose to delete preview files, for example if you've made some changes to your transitions or your effects here and you want to re-render you might as well go ahead and delete preview files. To do this, with the Timeline window active choose Sequence, Delete Render files, when you're prompted here click OK. To save time, Premiere Pro CS3 maintains existing preview files whenever possible. These preview files move along with their associated segment of a sequence. As you edit your project, when a segment of a sequence is changed, Premiere Pro automatically trims a corresponding preview file, saving the remaining unchanged segment. So in other words, these preview files are very much like media files, and you need to kind of keep track of them, make sure that Premiere Pro can find them when you open up a new session. So that will conclude my review of previewing files in Premiere Pro CS3. That will also wrap up this section of the tutorial on editing techniques. And it's a very important fundamental section. You've learned about the basic editing workflow in Premiere Pro. You've learned how to storyboard edit, how to perform insert and overlay edits, as well as rolling and ripple edits. Next you learned how to perform three-point and four-point edits, as well as how to edit clips in the Timeline. You've learned a variety of Timeline editing techniques such as splitting, copying, pasting clips, as well as removing clips and frames. You've learned how to change clip duration and speed, also how to export and freeze frames. You've got a nice tutorial on multi-camera editing, and I wrapped up this section with some demonstrations on how to preview sequences in Program view.
