AI video editors can generate transcripts, identify pauses, suggest highlights, and create draft captions. These features speed up selection, but short-form video still needs deliberate pacing, accurate words, and a composition designed for a vertical screen.
Begin with the message
Choose one clear idea for the clip. Review the source footage and identify the strongest opening, supporting moment, and final action. An automatically selected highlight can miss context or emphasize a sentence that does not represent the complete recording.
Verify transcripts and captions
AI captions often mishear names, accents, technical terms, and numbers. Correct every line, divide text into readable phrases, and keep captions away from platform controls. Use strong contrast and a font size that remains legible on a phone.
Reframe for vertical video
Use a 9:16 canvas for Reels, TikTok, and Shorts. Keep the speaker or subject inside the central area and review every shot after reframing. Automatic tracking can drift when subjects cross, leave the frame, or are partially hidden.
The video editor provides browser-supported upload, trim, aspect ratio, text, and export controls. It should only present AI transcription or smart-cut actions when a real processing service is available.
Final short-form checklist
- Confirm the first seconds communicate the topic.
- Remove pauses only when speech still feels natural.
- Check caption spelling and timing.
- Keep logos and text inside safe margins.
- Listen for audio cuts and synchronization problems.
- Export in a browser-supported format and play the download fully.
AI can create a useful first assembly, but the final edit must preserve meaning and play reliably. Review the complete file on a second device before publishing, particularly when a platform requires a specific MP4 codec or resolution.
