An overlay is anything you layer on top of your recording without replacing what’s already on screen. Open Overlay in the editor sidebar and you’ll find them all in one place, each with its own section. This is different from media (B-roll), which swaps out a whole slot of your layout. An overlay floats above everything for the stretch of time you choose.

What you can add

How to add one

The flow is the same whichever you pick:
  1. Open your video in the editor.
  2. Move the playhead to where you want the overlay to appear.
  3. Open Overlay in the sidebar.
  4. Click the plus button beside the section you want.
  5. Adjust it on the canvas, then set its timing on the timeline.
A selected time range wins over the playhead. If you have a range selected — on the timeline or in the transcript — the new overlay starts at the beginning of that range instead of at the playhead, and selecting several ranges adds one overlay to each. Clear the selection first if you want the playhead to decide.Text, blurs, highlights, and images fill the whole range. A video or sound shorter than the range does not stretch to fill it — the card ends when the clip runs out.
You can also drag image, video, or audio files straight from your computer onto the timeline. Tella adds images and videos as media overlays and audio as sound effects, and saves them to your Personal library. See Drop files onto the timeline.

They all share one timeline

Every overlay is a card on the same timeline, and overlapping cards are stacked onto separate tracks automatically — so you can run a blur, a caption, and a logo at the same moment without any of them hiding the others. Selecting, moving, trimming, splitting, and copying work the same way for every type. Changing a card’s track order applies to the visual overlays — media and text — because that order is what stacks them on the canvas. See Work with the multi-track timeline.

Choosing between an overlay and a layout

Reach for an overlay when the recording should stay visible underneath. Reach for a layout with media when the visual should become the content — a full-frame screenshot or title card, with your camera in a bubble beside it.

Other ways to put words on screen

Text overlays are written by you and placed wherever you like. If you want words driven by what you said instead, use:
  • Subtitles — captions generated from your transcript. See Style subtitles.
  • Chapters — section labels viewers can navigate by. See Chapters.
  • Your logo — a persistent mark on every video, set once with custom branding.
