Exporting & Rendering

Once you've finished editing your segments and adding overlays, iviCut renders your final project directly in the browser — no upload, no waiting for a server.

Video Export

iviCut uses FFmpeg.wasm to process your video during the export phase:

  • Burned-in Captions: If you've created subtitles, they are rendered directly into the video file, ensuring they display on any device or platform without a separate file.
  • Privacy-First Rendering: Everything happens locally on your machine — no video data is ever uploaded to a server.

SRT Export

Prefer a separate caption file? Use the SRT Export feature:

  • Standard Format: Download your subtitle tracks as .srt files, compatible with YouTube, Vimeo, and most professional video players.
  • Accurate Timing: The exported file preserves all your timing adjustments and text edits from the Cue Editor.

Platform-Optimized Aspect Ratios

Select the right format for your target platform before exporting:

  • 16:9 — YouTube, presentations, and widescreen displays
  • 9:16 — TikTok, Instagram Reels, YouTube Shorts
  • 1:1 — Square format for social media posts

You can set the aspect ratio at any time in the canvas settings.

Data Persistence

While you work, your project data — including subtitles, overlays, and segment metadata — is saved via IndexedDB. If you accidentally reload the page before exporting, your work remains intact.
