You can also paste a picture with Ctrl+V. Videos play without sound.
Realistic scenes Landscapes drawn from equations: sky, sun, clouds, mountains, haze and a lake. They are procedural, so they are made-up places, not photos. Use one as a background, then add your text or subject on top. Press play to see it move.

Time my lines to the speech in my video Add every few seconds instead 🎤 Dictate with the microphone
“Time to speech” measures when someone is talking in your video or sound (from the real loudness, every 20 ms) and places each line there. You still supply the words. “Dictate” uses your browser’s speech recognition and the microphone, so it needs Chrome or Edge and an allowed microphone.
Music Add a music or sound file
MP3, WAV, M4A or OGG. It is mixed into the exported video together with the video’s own sound.

Real 3D from your own equations x(u, v), y(u, v), z(u, v): orbit it, move it, measure it, and see exact error reports. Exact area and volume are shown only where the shape's formulas apply.
Equation explorer Type any equation and watch it become a 3D model, or browse ready-made models in six categories. Every model says how it was made: Exact Numerical Procedural Artistic

Not included: reconstructing 3D shape from one photograph, fluid or finite-element simulation, ray-traced rendering, and anything needing a server. The editor tells you when a request falls outside what it can do reliably.
Graphs and calculus
Type any formula. You get the graph, its slope (derivative), the area under it (integral) and where it hits zero, all worked out live.
Math art
Each one is drawn from equations. Use it as a background or an accent, then change its numbers in Edit.
