In most cases, you can start a project simply by using one of the presets provided in the New Project dialog box. The presets included with Adobe Premiere Pro include common project types. Preserve editing quality by using a preset that conforms to the specifications of your original assets. For example, if your project uses footage mostly in DV format, use a DV preset. If you need to specify lower quality settings for output (such as streaming web video), don’t change your project settings—instead, change your export settings later.
If your computer has a capture card compatible with Adobe Premiere Pro, its own optimized presets may appear in the Available Presets list.
The project settings must be correct when you create the project file. Once a project is created, some project settings, such as the timebase settings, are locked. This prevents unwanted inconsistencies that could result from changing project settings later.
