The downside to audio conforming is that the process consumes time and disk space when you import files. Although Premiere Pro can extract plenty of information from a standard WAV, MP3, or AIFF audio file, by conforming a file Premiere creates a standard audio file format optimized for access time, waveform display, playback, and effect application. ConformingĪ lot of high-end audio editing and video editing applications adjust their imported media, conforming it to a format that accurately matches their settings and can be accessed easily. Premiere Pro supports up to 96kHz or 96000 samples per second. For example, 48kHz means your audio file has 48000 audio samples per second. The sample rate reflects the number of samples in your audio file. The kHz value is your sample rate, also known as your Hertz rate (1kHz equals 1000 Hertz). The more bits, the clearer the detail in the audio file. The bit value (bit depth) reflects the resolution of your audio file. Your audio project settings are commonly expressed as 16-bit 48kHz. If you want to do dynamic scale adjustments, zooms, and other manipulations, be sure to turn off the Preference. Remember, however, this setting affects auto-scaling only when you add that file into a sequence. If you do not want to auto-scale imported items, either turn off the Preference check box or select the auto-scaled file in the Project panel and turn off auto-scaling. If you import a small, 320 x 240 QuickTime clip, you can use a new Preference check box (Default Scale to Frame Size) to apply a scale adjustment to the smaller clip, enlarging it to match your project's dimensions when you drop it into any of the project sequences ( Figures 3.4).
Say that you have project settings of 720 x 480 using DV as your editing mode. VideoĪ new feature for Premiere Pro 2.0 is the option to have all your video, including stills, scaled to your project dimensions upon importing. XML files can be read and opened in word processing applications, making it easy to search for specific fields of information. Instead, XML files contain readable human language and data followed by descriptions of the data. None of the XML file data is compressed, and it is not written in a binary language. Importing FilesĪ cousin of the HTML format, XML is a self-describing file format that is used to transfer information from one place to the next.
To get a better sense of clip handling, take a look at how to import and open your media.
Because Premiere Pro supports offline files in the timeline, if you accidentally delete a master clip from your hard drive, all project clip instances will remain intact with the media appearing offline. Deleting a master clip from your project will delete all of the subclips, because the subclips point to the master clip to get their information. Deleting an edited subclip does not delete the master clip. This subclip, if opened separately, can access all the information of the master clip, while honoring its assigned In/Out points and duration. If clip01 is edited into a sequence using only half of its duration, the edited instance of clip01 in the sequence is referred to as a subclip or a child of the master clip. It is the master file from which all edited and used instances will come. When you first import a file into your project, that file is referred to as a master clip. Figures 3.1a and b The Project panel can display its contents in Icon view (above) or List view with icons turned on (left)īecause so many of these functions relate to clip handling, it's important to understand how Premiere Pro manages clips.
