Make animated text
Titles for a video, an animated caption for a reel, a lower third or a short kinetic quote: add a text layer, give it a move and render it. Slop Effects works like a small motion design app in your browser.

How to do it
- Pick a composition size: YouTube 1920×1080, Shorts/Reels/TikTok 1080×1920, square, portrait, 4K or custom.
- Add a text layer from the Layer menu and type your words; choose the font, weight, size and colour.
- In the Motion tab, choose Animate in and Animate out (Fade in, Slide up, Pop or Spin in), or set your own keyframes for position, scale, rotation and opacity.
- Shape the timing with the easings and the Graph editor, and add effects such as Glow or Drop shadow.
- Press Render and choose MP4, WebM or a PNG sequence.
For text you can lay over other footage, tick Transparent background and render a PNG sequence: the frames keep their transparency and most video editors import them as one clip.
Your files stay on this device: Slop Effects runs in your browser, with no upload, no account and no watermark.
Questions
Can I export with a transparent background?
Yes, as a PNG sequence in a ZIP. MP4 and WebM are rendered with the background colour.
Can I use my own fonts?
The font picker has a set of fonts and a Get more button for more. Text options are font, weight, size, alignment and colour.
How long can an animation be?
A composition can run from 0.1 to 600 seconds, at 24, 25, 30, 50 or 60 frames per second.
Is anything uploaded?
No. Editing and rendering happen in your browser.
