Video editing guides

Start with the change you want to make. Each guide explains the controls, gives an example and shows what to check before publishing.

• AI video editing with prompts: a practical guide

  AI video editing works best when you give it a specific job. Start with a clip you own, describe one change, and review the result before adding another.

• How to turn a YouTube video into a short clip

  A useful short clip tells one complete idea. Pick a moment that makes sense without the rest of the video, then adjust its timing and framing for the people watching it.

• Resize a video for Reels: crop, fit and captions

  Changing aspect ratio changes what your audience sees. A good vertical edit keeps the important action visible and leaves enough room for captions and playback controls.

• Edit video captions: text, style and placement

  Editable captions are a separate text layer. Text burned into a source video is part of its pixels. Knowing which you have determines whether you can correct, restyle or remove it.

• Change video speed and calculate clip duration

  A clip at 3x speed lasts one third as long. Divide the selected source duration by the speed multiplier: a 30-second selection becomes approximately 10 seconds.

Rendering availability is shown in the workspace. Reading guides and reviewing settings does not submit a video job.
