Questions about browser-based creator tools
Do I need to install an editor?
No. The tools run in a modern web browser. Larger media jobs work best on a desktop with enough free memory.
Do exports include a watermark?
No. Tubelexity does not add a logo or watermark to exported media.
Why do some tools download a media engine?
Video encoding uses FFmpeg.wasm, which is loaded only when a processing tool needs it. The download contains code, not your media.
