Video Editing with Captions

A video editor shows your video in a preview window above a stack of tracks lined up in time. The video track holds clips you can see, the audio track holds the sound, and the caption track holds the words on screen. Editing means trimming what is too long, joining clips smoothly, balancing the audio, and adding captions so every viewer can follow along.

The Four Jobs of an Editor

1. Cut — remove parts that are unwanted, repeated, or off-topic.
2. Transition — join two clips with a smooth crossfade or wipe instead of a hard jump.
3. Caption — type the spoken words on screen so deaf viewers, or anyone watching with the sound off, can follow.
4. Audio — set the volume so music supports the voice without drowning it.

Common Edit Operations

• Cut — slice a clip at the playhead and remove a section in one click.
• Trim — shorten a clip by dragging its start or end inward.
• Ripple delete — cut a section and slide everything after it back to fill the gap.
• Crossfade — fade the end of one clip into the start of the next.
• Caption — show the spoken words as text along the bottom of the frame.
• Color grade — adjust brightness, contrast, and tint to set the mood.
• Voice-over — record a narration track over the video.
• Export — save the finished timeline as a single playable video file.

Why Captions Matter

• Captions help deaf and hard-of-hearing viewers follow every word.
• Captions help viewers in noisy places (or with the sound off) still understand.
• Captions help viewers learning a new language read along while listening.
• Captions must be accurate and timed — they appear when the speaker says the word, not before or after.
• Captions stay on screen long enough to read, then disappear before they crowd the next line.
