mimicTo edit a video with AI, give the tool your raw clip and a style, let it make the first edit (cuts, captions, zooms, titles), then refine it by typing what you want changed in plain words: “bigger captions”, “cut the pause at the start”, “zoom in when I say the price”.
The first edit saves the most time. The typed changes replace hunting through menus and keyframes.
What AI does in a talking-video edit
| Job | By hand | With AI |
|---|---|---|
| Transcript | Type it out or skip it | Every word, with timings |
| Dead air and stumbles | Cut each gap on the waveform | Pauses and false starts cut together |
| Captions | Type, split and time each line | Timed to every word, in the style you pick |
| Zooms and titles | Keyframe each one | Placed on key lines; hook written for you |
| Product shots | Line each one up with what you say | Laid in where you mention them, kept off your face |
Silence detection alone only finds quiet stretches below a loudness threshold (FFmpeg, 2026). Working from a transcript is what lets AI remove an “um” or a repeated line too.
Editing with Mimic, step by step
- Pick a style: a built-in one (Punchy UGC, Top list, Clean captions…) or copy any video’s by pasting its link.
- Add your clip, plus any product photos, screenshots or demos.
- Make the video. Mimic does the first edit.
- Open it and tap Ask AI to change anything by typing, or tap a caption, clip or card to change it by hand.
- Export and post. Editing and exporting again don’t use another video.
Prompts that work
“Make the captions 30% bigger.” · “Use Anton for the captions with a black outline.” · “Turn the captions yellow.”
“Cut every pause longer than half a second.” · “Remove the first two seconds.” · “Slow down the clip at 0:08.”
“Zoom in when I say the price.” · “Add a flash on the hook.” · “Add a title at the top: 3 apps I can’t live without.”
“Show the app’s App Store page when I mention it.” · “Make the demo full screen.” · “Remove the second card.”
“Make it better.” · “More viral.” · “Fix it.”
Say what, where and how much. One change per prompt is easiest to check; you can chain them.
What to check before you post
- Spelling of brand and product names in captions.
- Your face: no text or card covering it. Mimic keeps them off, but check anything you added by hand.
- Safe zones: nothing important under the platform’s buttons. See safe zones.
- The first three seconds: does the hook land? See how to write a hook.
Questions
Can AI edit a whole video for me?
For talking-to-camera videos, mostly yes. AI can transcribe you, cut the pauses and false starts, caption every word, add zooms, titles and sounds, and lay in your product shots. You still decide the style and check the result.
How do I edit a video by typing what I want?
Open the video in an editor with an AI assistant (in Mimic it's Ask AI) and type the change in plain words, such as "make the captions bigger" or "cut the pause at the start". The AI changes the edit and you see the result straight away. Every change can be undone or adjusted by hand.
What prompts work best?
Specific ones: what to change, where, and how much. "Make the captions 30% bigger" beats "make it better". Mention a time ("at 0:04") or a word the change should land on.
Does AI editing use my footage to train models?
It depends on the tool. Mimic uses your videos only to make your edits, never to train AI models, and you can delete them at any time.
Is AI editing good enough for brand deliverables?
For UGC it usually is, as long as you check three things: captions spelled right (especially brand names), no text over your face or the product, and nothing in the platform safe zones.
