A block at each end of the timeline for a title card or a sign-off, placed and timed like anything else on the clip.

41 named animated caption styles (Pop, Neon, Gold, Sunset, Slant and more) with a live preview so you pick the exact look before you render your short-form clip.
Fifty one caption presets, each with a live preview that renders in the browser before you commit to anything. You see the exact look, the exact font and the exact animation, and only then do you export.
The preview is the point. A preset list that only shows a static sample is a catalogue of promises: you pick, you render, you wait, you find out. Here the preview uses the same style definition the renderer burns, so what moves on screen is what lands in the file.
Forty seven fonts are installed on the render machine. That number matters because a picker offering fonts the renderer does not have is a picker that lies, and ours did until we counted both sides and made a check fail the build when they disagree.
Captions themselves cover 99 languages. Word level timing, the kind that highlights one word at a time, covers 41 of those. The rest get sentence level timing, which is a real difference and we would rather say it than let you discover it.
Drop your own files in the editor and drag them onto the clip or straight onto the timeline, where you point. A sound you import from the music tab lands in the same place, so there is one library to find it in and one place to delete it from.

Katto detects every camera change, you add your own cuts with the S key and drag any boundary onto the exact frame. Each shot keeps its own framing, and a magnet snaps b-roll, text and sounds onto the cuts.

Highlight what matters in yellow, lime, cyan or pink, then filter the transcript to one colour or several: everything else steps out of the way and you are left with your passages, each with its timecode.

Search the music and sound-effect libraries as you type, filter by mood or category, star the ones you keep coming back to, and see every track's real length. Each mood has its own colour and icon, so you spot the right kind of track before reading a single name. Import your own audio from the same place.

Use one track for the first half of a clip and another for the second: each music sits on its own timeline row, drops where your playhead is, and can be dragged or trimmed. They never play over each other, in the preview or in the exported file.
More than one music bed per clip, each on its own lane, each with its own position in time. One track for the first half, another for the second, is two clicks.
A bed dropped over one that is still playing cuts the first one short rather than layering both, because two music tracks at once is never what you want and discovering it at export is expensive.
Auto ducking lowers the music under the voice, and the music and voice levels are separate sliders rather than one balance control.
Browse royalty-free stock footage without leaving the editor: results fill the panel as you type, hovering a clip plays it, and one click drops it on the timeline at your playhead. Or upload your own B-roll. Katto can still find the moments for you and suggest footage for each one.
Search a stock library from inside the editor, watch a clip play in the panel, and drop it on the timeline only once you have seen it.
Before this, choosing b-roll meant picking from thumbnails. A thumbnail tells you the subject and nothing about the motion, which is the half that decides whether a shot works over a sentence.
You can also bring your own file. An uploaded clip follows exactly the same path as a stock one, so nothing about the render changes depending on where the footage came from.
Auto emojis are suggestions, not decisions: drop one from a single word, or clear every emoji on the clip with one button next to the transcript.
Automatic caption emojis can be removed, one at a time or all at once, from the transcript panel.
They were added automatically and there was no way out: you either accepted every one or turned the whole caption style off. Now each emoji is an object you can delete like a word.
The subtlety was in the indexing. Rendered captions group words into lines, and the timeline addresses them one by one, so the emoji you clicked and the emoji that got removed were not always the same one. The two now agree.
A searchable sound-effects library alongside the royalty-free music.
