Video editing has its own vocabulary, and tutorials often assume you already know it. This glossary covers the terms that come up constantly for short-form and creator editing, explained in plain English.
Timeline & structure
Timeline — the horizontal track where your clips, audio, and effects are arranged in order
Keyframe — a marked point where a property (position, scale, opacity) is set to a specific value, letting the software animate between points
Jump cut — cutting between two shots of the same subject without changing angle
J-cut / L-cut — when audio from the next or previous clip starts before or after the visual cut, smoothing the transition
Match cut — a cut between two shots with similar composition or motion, making the transition feel seamless
Visual terms
B-roll — supplementary footage cut over your main shot
Aspect ratio — the width-to-height shape of your frame (16:9, 9:16, 1:1)
Color grading — adjusting a video's color and tone for mood or consistency
Chroma key — removing a solid-color background (usually green) to composite a new one
LUT — a preset color transformation applied to footage for a consistent look
Audio terms
Ducking — automatically lowering music volume when dialogue is present
Room tone — ambient background noise recorded in silence, used to smooth audio cuts
Sound design — the deliberate use of sound effects and audio layers to enhance a scene
Export & delivery
Bitrate — how much data is used per second of video; higher generally means better quality at a larger file size
Codec — the compression format a video is encoded in (H.264 is the most common for web delivery)
Render — the process of processing all edits into a final exported video file
Now that you know the terms, put them to work — EseCut's timeline supports all of the above natively.
