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. You can also use the Properties feature to alert you to the presence of any dropped frames in a

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.
