# Screen Effects by Tella

> Tella is an all-in-one screen recorder with AI video editing, that lets startups and entrepreneurs create quick video messages, social demos, and long-form videos without switching apps. Recording, editing and sharing in one tool.

## Summary
Screen effects make recordings easier to follow and more polished. Tella can generate zooms from recorded clicks, redraw the cursor from mouse data, and add blur or highlight overlays after recording.

## Auto-apply
Auto Zoom turns recorded clicks and cursor movement into a first pass of zoom effects. Every generated zoom remains editable, so it can be moved, resized, restyled, or removed.

## Multi-track editing
Zooms, blurs, and highlights live on their own tracks above the transcript. Effects can be moved, resized, split, or edited together while staying synchronized with cuts and trims.

## Zoom effects
- Auto mode follows the recorded cursor; Manual mode locks onto a fixed target
- Scale from 100% to 350%
- Select a range on the timeline or in the transcript and press Z to add a zoom

## Animated cursors
- Choose a macOS, Windows, or touch cursor at any size
- Smooth the recorded path and add movement tilt
- Add a click spring and ripple, or hide the cursor while it is inactive

## Blur & highlight
- Blur hides passwords, email addresses, customer data, or anything else that should stay private
- Highlight masks everything except the area viewers should focus on
- Drag either end on the timeline to control exactly when the effect appears

## Platform support
The native macOS and Windows apps capture the cursor and click data required by Auto Zoom and animated cursors for any capture; the Chrome extension captures it for browser tabs. Zooms, blurs, and highlights can also be applied to uploaded videos.

## Frequently asked questions

### What counts as a screen effect?
Anything Tella draws on top of a screen recording to guide the viewer: zooms, animated cursors, blur, and highlight overlays.

### Do I need to plan effects before recording?
No. Record as normal. Tella captures cursor and click data alongside the screen, and every effect can be added, moved, or removed in the editor afterwards.

### Which recordings support screen effects?
Zooms, blurs, and highlights work on screen recordings and uploaded videos. Animated cursors and automated zooms need cursor data, which the Mac and Windows apps record for any capture and the Chrome extension records for browser tabs.

### Can effects overlap?
Yes. Zooms, blurs, and highlights each sit on their own timeline, and overlapping effects are placed on separate tracks so each one can be adjusted independently.

### Do effects follow my edits?
Every effect is timed to the edited video, so when a section is cut or a clip is trimmed, the effects around it stay in sync with what viewers see.
