The editing workshop
Six interactive tools for learning and planning edits. They manipulate sample data and CSS demonstrations only — they do not import, render, transcribe or export real video or audio files.
Video Timeline Builder
Assemble a short-form video structure across five tracks. This is a browser-based educational simulator: it previews labels and timing, not real footage, and cannot export video files.
Keyboard: focus a clip, then Alt + ←/→ to reorder or Delete to remove.
Subtitle Studio
Style captions over a 9:16 video-style canvas. This is a subtitle design preview — it does not transcribe audio. Sizes are expressed for a 1080 px-wide frame so you can replicate them in CapCut, Premiere Pro, Resolve or Final Cut Pro.
Mobile-safe guidance: keep captions out of roughly the top 11% and bottom 21% of a vertical frame and away from the right-hand action buttons. Exact UI positions vary by app and device.
Effects Playground
Each badge tells you whether you're seeing a working CSS demonstration or a concept that needs dedicated editing software on real footage.
Before & After
CSS-generated illustrations of editing treatments — not product benchmarks or real footage. Drag the frame or use the slider.
Editing Workflow Quiz
Six questions, no account, no personal data. Revise or restart anytime.
Creator Workflow Planner
Organise editing tasks by stage. Saved only in this browser (if storage is available) — never synced to any external service.
