What is a J-cut in video editing?
A J-cut is when the audio from the next clip starts before its video appears, so the viewer hears the upcoming scene while still seeing the current one. The audio track extends leftward into the preceding clip, forming a 'J' shape in the timeline.
What is a keyframe in video editing?
A keyframe marks a specific point in time where a property's value is set, allowing Premiere to interpolate changes between two or more keyframes. They drive animation for opacity, position, effects, and audio levels.
What does the Overwrite command do in Premiere Pro?
Overwrite (period key) replaces whatever is at the timeline In point with the source clip for its exact duration. Unlike Insert, it does not push downstream clips, so the total sequence length shortens by the duration of the source when no gap exists.
What is the difference between bitrate and bit depth in video?
Bitrate measures how many bits per second of data are processed, affecting file size and quality of compression. Bit depth determines the number of colors or tonal values per pixel (e.g., 8-bit = 256 values, 10-bit = 1024), affecting color accuracy and gradation smoothness.
What is the keyboard shortcut to add a marker in Premiere Pro?
Press M on the timeline (or in the Program monitor) to add a marker at the current playhead position. Shift+M moves the playhead to the next marker.
What is a Gang (linked) selection on the timeline?
Linked selection means audio and video tracks of a clip move together on the timeline. Disabling linked selection (chain icon) lets you move audio independently from video for advanced edits.
What does the keyboard shortcut 'Y' do in Premiere Pro?
The Y key activates the Slip tool. Clicking and dragging on a clip with this tool shifts the clip's In and Out points together by the same amount, changing what portion of the source media is shown while keeping the timeline duration constant.
What is the keyboard shortcut 'J, K, L' used for in Premiere Pro?
J plays backward, K stops playback, and L plays forward. Pressing J or L multiple times increases shuttle speed up to 8x. These transport shortcuts enable fast scrubbing through footage without using the mouse for navigation.
What is the function of the Selection tool (V) in Premiere Pro?
The Selection tool (V) is the default pointer for selecting and moving single clips in the Premiere Pro timeline. It selects only the clip you click, leaving adjacent clips untouched unless you also drag them.
What does the keyboard shortcut Ctrl+Z (Cmd+Z) do in Premiere Pro?
Ctrl+Z (Cmd+Z on Mac) undoes the most recent edit. Multiple presses step backward through the edit history, while Ctrl+Shift+Z (Cmd+Shift+Z) redoes actions that were undone.
