How to Make YouTube Shorts With AI

Shorts have different production rules than long-form

The general AI voiceover workflow we cover in How to Make AI Voiceovers for YouTube still applies, but Shorts have a few constraints specific to the format that change how you should approach each step.

1. Write the hook first, script second

Shorts are judged in the first 1-3 seconds — if the hook doesn’t land, the rest of the script doesn’t matter. Write and test your opening line before fleshing out the rest, and keep sentences short enough to be spoken at a pace that matches Shorts’ quick-cut style.

2. Generate narration in short, tight sections

Because Shorts run a couple of minutes at most, this is one production step that’s actually faster than long-form: generate your narration in one or two passes rather than many sections, listen back, and regenerate the whole clip if something’s off — the cost in credits is small at this length. See ElevenLabs Pricing for how credit usage scales with script length; a short clip uses meaningfully fewer credits than a long-form video.

3. Shoot or generate for vertical (9:16) from the start

Long-form footage cropped down to vertical often loses the framing that made it work. If you’re using AI-generated visuals or stock footage, confirm vertical/9:16 output before you build a whole video around footage you’ll have to reshoot or replace. If you’re editing manually, check that your editor’s export settings match vertical format before you finish — see our VEED review for a browser-based editor with subtitle support that works for this.

4. Add subtitles — Shorts are watched sound-off more than long-form

Auto-generated captions matter even more here than on long-form video, since Shorts autoplay with sound off by default in a lot of viewing contexts. Run an auto-subtitle pass and manually check it, especially for names or niche terms an auto-subtitle tool might misread.

5. Keep a fast, repeatable loop

Shorts reward frequency more than any single video’s production value. Once your voice, visual style, and editing steps are settled, aim for a workflow you can repeat quickly rather than perfecting every individual clip — that’s the practical trade-off of the format.

Choosing a voice tool for Shorts specifically

Because Shorts use less audio per video, the credit-based pricing on tools like ElevenLabs can work out cheaper than it looks for long-form — see Best AI Voice Generators for YouTube Shorts for how that math plays out and which tools we’ve covered.

Common mistakes

• Spending most of your effort on the middle of the video instead of the first few seconds
• Reusing long-form footage that wasn’t shot or generated for vertical format
• Skipping subtitles because the clip feels “too short to need them”
• Over-producing each Short instead of building a repeatable, fast workflow
