Time Overlay

Time Overlay is a free, local-first tool that builds countdown timers in your browser so you don’t have to upload footage to a render service. You set the duration, look and output settings, then export a transparent sequence or a single video with alpha for use in editing or live streaming.

It supports formats editors and streaming programs commonly accept, so you can drop the timer into OBS, Streamlabs, CapCut, Premiere Pro, DaVinci Resolve and similar workflows without extra compositing work.

• Customisable display format, canvas size and style presets
• Placement controls and background modes
• Choose FPS and export quality
• Export transparent PNG sequences or WebM with alpha
