You want to use Clip > Modify > Interpret Footage to change a clips dip to 481ps. The clip has already been edited into a 24fps sequence. What happens to the clip in the timeline?

The Interpret Footage command alters the metadata that defines a clip's native frame rate. When you interpret a clip to have a frame rate of 48fps and place it in a 24fps sequence, you are instructing Premiere Pro to play back 48 frames of the source for every one second of timeline duration. Since the sequence can only display 24 frames per second, the clip's playback speed is doubled (200% speed, or twice as fast). To accomplish this, Premiere Pro must discard half of the source frames, resulting in only every other frame being displayed.

A. To play twice as fast, frames must be dropped to fit the sequence's lower frame rate; it is impossible to display every frame.
B. Interpreting a clip at a higher frame rate than the sequence causes it to play faster, not slower.
C. This describes the effect of creating slow motion by interpreting a high-frame-rate clip (e.g., 48fps) as a lower frame rate (e.g., 24fps). ---

Section: "Change a clip’s frame rate"

Content: The documentation explains

"When you change the frame rate of a clip

you change its speed and duration." It provides an example of interpreting a 30-fps clip as 15 fps to make it play at half speed. The inverse logic applies to the question's scenario: interpreting a clip at a higher frame rate (48fps) than the sequence (24fps) will cause it to play back faster.

Section: "Creating a freeze frame and slow motion"

Content: This chapter details that using Interpret Footage to set a frame rate lower than the original creates slow motion by playing every frame at the new

slower rate. This principle confirms that setting a higher frame rate will produce the opposite effect: fast motion

which necessitates dropping frames to match the sequence's rate.

Section: "Interpret Footage"

Content: The guide states

"This method changes the metadata of the clip to a new frame rate. For example

a 60fps clip can be interpreted as 24fps. This will play the clip back at 40% speed

and every frame of the original clip will be used." This directly supports the concept that interpreting footage changes its playback speed based on the ratio of the new frame rate to the sequence frame rate. For the question's scenario (48fps in a 24fps sequence)

this ratio is 2:1

resulting in 200% speed.
