WHAT IS REEL VIDEO CAPTIONS
Reel Video Captions is a free, browser-based auto-caption tool for short-form video. Drop in an MP4, MOV, WEBM, or MKV, and it transcribes the audio with OpenAI Whisper at word-level timing, then burns the captions directly into the video pixels with FFmpeg. You download a captioned MP4 — no watermark, no sign-up, no email gate, no monthly minutes cap.
The captions survive re-uploads to TikTok, Instagram Reels, and YouTube Shorts because they are baked into the pixels rather than added as platform overlays that get stripped. Four style presets cover the common short-form looks (bold yellow, comic, minimal, sleek), and you can switch between them in one tap. As of April 2026, Reel Video Captions is free in public beta with no upgrade tier.
Every preset is one tap. Change your mind — change it again. No re-render fees.
