Auto Edit

Auto Edit works from the words in your clips and builds the video out of your best lines. Silence, repeated tries at a line and lines that aren't clear are always cut, whichever options you choose. Each place where one line ends and the next begins is a jump cut; the options below decide how those cuts sound and look.

Every Auto Edit makes a new version of the video, so trying other options never replaces a version you already have. On the Mac you can also start one from the menu bar with Video, then Re-cut.

These four cost nothing extra. Two of them are on when you start.

• J and L Cuts (on): your voice runs a moment past each cut, so one line flows into the next. See J cut and L cut.
• Remove Ums (on): cuts um, uh and erm out of your lines.
• Punch-in Zoom (off): zooms in after jump cuts, and slowly on long shots. See punch-in.
• Let AI Reorder (off): puts your lines in the best order. Leave it off when you filmed a script in the order you want it.

Two extras add to the cost, and you choose them before the cut.

• Captions (10 credits, off when you start): word-by-word captions you can restyle. They are charged once per edit, and you change the look and fix words afterwards in the editor. See Captions.
• Spoken Overlays (5 credits): while filming, say "overlay" and a few words, like "overlay the before photo". Auto Edit cuts those words out and places the overlay from your library that matches best; when two match, the newest wins. It starts off for a new version, so check it's on before you press Auto Edit. With no overlays in your library there is no switch: the iPhone and Mac apps show an Add Overlays button, and the web says to add overlays first. See Spoken overlays.

Under Advanced, you set the shortest and longest time a spoken overlay stays on screen.

Auto keeps every good line, however long that makes the video. Most ads aims for about 30 seconds. Custom lets you pick any length from 10 seconds to 3 minutes, in 5-second steps.

With a length picked, Auto Edit keeps your strongest lines, your hook and your call to action, and drops the rest until the video is near your pick. It may land a few seconds over or under, so treat the length as a target rather than an exact cut.

An Auto Edit costs 40 credits. Captions add 10 and Spoken Overlays add 5, so a typical video with both comes to 55 credits. The Auto Edit button shows the total before you press it, and if a version fails, its credits come back.

Trimming, swapping clips and exporting the finished version cost nothing. When your balance is short, the Auto Edit button becomes Get Credits and tells you how many the version needs. Credits shows where to see your balance and what else costs credits.

With Bang AI added to ChatGPT, Claude or Claude Code, ask in your own words, or paste one of these:

• Auto Edit understands English and Spanish speech, and it is made for videos where you talk to the camera.
• A version holds up to 50 clips. Each clip's sound can be up to 30 minutes long; on the web, a longer clip uploads without its sound.
• A Custom length runs from 10 seconds to 3 minutes, and the cut may land a few seconds over or under it.
• Silence, repeated tries at a line and unclear lines are always cut. No option keeps them.
• In the iPhone and Mac apps, Batch Auto Edit cuts up to 20 videos at once.
• From a chat, only ChatGPT can start an Auto Edit, and only through its card: the chat never receives your files.
