How can I edit a video after an AI draft is ready? Work through one scene at a time: prepare the words, create captions, add or review voiceover, then watch the result with and without sound. This AI video editing sequence keeps the message, picture, text and audio aligned before delivery.
Start with an existing editable project and a short scene brief. This guide covers the first caption and voiceover pass. For deep caption correction, SRT handoff, music and sound effects or a failed voiceover, use the focused guides linked below.
The practical answer to "How can I edit a video?" is to fix the earliest mismatch first rather than polish every scene at once.
1. Prepare the scene before editing
Read the script against the visual scene. Reduce lines that contain two ideas, mark names or numbers that need careful pronunciation, and choose the words viewers must read. Keep the spoken script and caption text aligned in meaning without turning every pause into a new caption block.
Make a small scene card for the first scene you will review:
Use the card as a repair brief. Keep names and numbers spelled consistently in the spoken and caption versions, then check them at normal playback speed.
2. Create the caption draft
CapCut's AI caption generator uses the sequence Captions → Auto captions → spoken language → Generate. Use it to create the first text pass, then proofread the result instead of treating recognition as a final transcript.
Check three points in the scene:
- the first caption after a scene cut;
- the longest caption in the scene; and
- the last caption before the next cut.
For each checkpoint, verify the words, punctuation, line breaks, start and end points. The caption should clear before the next idea and should not follow a previous scene into an unrelated shot. Correct the earliest small text error before moving to the next scene.
3. Add or review voiceover from a text layer
CapCut's text to speech tool separates text entry, voice selection, preview and generation. Add or open a text layer, enter the narration, select the layer, choose Text-to-Speech, select the language and voice, then preview the line before continuing.
Keep the narration tied to the scene card. Names, numbers and product terms should match the caption spelling. A short sentence is easier to align with the picture and easier to repair than a paragraph that crosses several scene changes.
4. Review text picture and audio together
Play the draft with captions visible and audio enabled. Check that each caption appears while the related words are spoken, that the voice begins and ends with the correct scene, and that background audio does not mask speech. When you add text to video, check the text against the visual action rather than judging it as a separate decoration.
Then watch once with sound off. The captions should still communicate the main point. Use this review table:
Repair the first mismatch you find. Do not polish later scenes while an earlier caption is mistimed or a voice line is attached to the wrong visual beat.
Apply the checklist to one short scene
Use a single scene as a complete test before repeating the edit across the project. For a product demonstration, the review note might look like this:
Spoken line: "Open the product, choose the first setting, and preview the result." Caption blocks: Open the product / Choose the first setting / Preview the result Visual cue: the product opens, the setting changes, then the preview begins Voice check: "preview" is pronounced clearly and ends before the final visual change Silent check: the three caption blocks still show the order of the action
If the voice finishes after the preview begins, shorten the spoken line or adjust the scene timing before changing the caption style. If the captions are correct but the picture does not show the stated action, fix the source visual instead. Once this one-scene note passes with sound on and off, repeat the same checks for the next scene rather than changing every caption at once.
When you ask "How can I edit a video?" for delivery, repeat the same order on each scene: words, captions, voiceover, sound-on review and silent review.
Choose the next editing guide
Revise source wording before the caption pass. For background sound, use add music and sound effects. For inaccurate automatic text, use fix wrong auto captions. For a separate generation problem, use AI voiceover not generating.
When the scene passes both the sound-on and silent checks, return to the CapCut video generator for the next creation or edit pass. For the wider workflow, open the AI video creation guides.
