About clip properties

Adobe Premiere Pro includes clip analysis tools that you can use to evaluate a file in any supported format stored inside or outside a project. For example, after producing a video clip to be streamed from a web server, you can use clip analysis tools to determine whether a clip you exported has an appropriate data rate for Internet distribution.

The Properties feature provides detailed information about any clip. For video files, analyzed properties can include the file size, number of video and audio tracks, duration, average frame rate, audio sample rate, video data rate, and compression settings. The Properties window will not show all these properties for every clip. The data shown in the Properties window is determined by the file format of the clip being examined.

You can also use the Properties feature to alert you to the presence of any dropped frames in a clip you just captured. Use the data rate graph to evaluate how well the output data rate matches the requirements of your delivery medium. It charts each frame of a video file to show you the render keyframe rate, the difference between compression keyframes and differenced frames (frames that exist between keyframes), and data rate levels at each frame. The graph includes the following information:

Data rate: The line represents the average data rate.
Sample size: The red bars represent the sample size of each keyframed frame.
Differenced frames sample size: The blue bars represent the sample size of the differenced frames between compression keyframes.
