How to edit a talking-head video with AI
Film the whole script, repeating any line you stumble on. Give an AI editor the recording and a one-line brief. Check that it kept the best take of every line, that sentences finish, and that captions stay off your face. Then fix the first second, since that's where most viewers decide. This guide gives the numbers we use.

The steps
Film for the edit
Wider than you think: 16:9 leaves room to crop to 9:16 and punch in. When you stumble, pause and say the whole line again from the top, because a clean restart is easy to cut to. Film product shots and the room in the same session, for b-roll.
Write a one-line brief
Say what it's for, where it runs and what to lead with: "A 45-second Meta ad for our booking tool. Lead with the hours it saves." Skip the settings.
Check the takes first
Before you look at any styling, read through it as words. Is every line there, once, in its best take? Does anything repeat? Does a sentence stop halfway? This is where most AI edits go wrong, and no caption style can fix it.
Check the pauses
Pace is a matter of where cuts sit. Cut in the pause at the end of a phrase rather than mid-phrase, and keep a little room around a thought. Removing every gap makes speech sound rushed.
Keep the frame moving
A single static shot gets tiring. A punch-in of about 12% on a key word, held to the end of the line, adds energy without a new shot. Don't go past what the footage's sharpness allows.
Place captions for the platform
Keep them above the platform's buttons and off the eyes and mouth. Break lines at the ends of phrases, and don't emphasise more than one word on a page.
Use b-roll to show, not to hide
Lay it over the words it illustrates. A stock shot that merely looks related is worse than staying on the speaker.
Set the sound
Keep music about 12 dB under the voice, down to 14 in dense sections and never below 18. Master to about -14 LUFS for social.
Fix the first second last
Have the hook text on screen on the first frame, so it works with the sound off, and have the first visual change by about 2 seconds.
Where these numbers come from
These are the defaults we built into Pyntra after working through ad-editing research and real edits. They're starting points, and your footage may call for something different. In Pyntra, a performed script keeps every line, cuts in ads remove pauses above 280 milliseconds between phrases, music sits at -12 dB under the voice, and the mix defaults to -14 LUFS.
Common mistakes
| Mistake | What to do instead |
|---|---|
| Stopping the camera after a stumble | Keep rolling and repeat the whole line |
| Filming too tight | Leave room above the head and on both sides |
| Judging the edit by its captions | Read the words first |
| Removing every pause | Keep the breath between separate ideas |
| Covering every jump cut with b-roll | Cuts are fine on a talking head. Use b-roll when it shows something |
| Music as loud as the voice | Start about 12 dB under |
Questions
What does talking-head video mean?
A video where a person speaks to the camera, usually framed from the chest up. In AI tools the same phrase can also mean a generated avatar, so check which one a product means.
What's the best AI tool to edit talking-head video?
For finished versions from a brief, Pyntra. For hand editing through a transcript, Descript. For short clips on a phone, Captions. See our comparisons.
How long should a talking-head ad be?
There's no one length. Pyntra's limits with no length set are 90 seconds for TikTok, Reels and Meta ads, 60 for Shorts and 180 for YouTube in-stream. Shorter usually needs a stronger hook, so test versions.
