How to turn audio into a video with captions

TikTok, Reels, Shorts, and LinkedIn are video feeds, so an audio file has nowhere to go. An audiogram fixes that: it pairs your audio with moving visuals and on-screen captions, so a podcast moment, a voice note, or a lesson can be followed with the sound off.

Turn an audio file into a captioned video

• Open the ClipMint studio and drop in your audio: MP3, WAV, M4A, AAC, FLAC, OGG, and Opus all work.
• Generate the captions. Auto-detect the language or pick it when needed, and turn on speaker detection for interviews.
• Pick a visualizer, a color palette, and a solid or gradient background.
• Choose the canvas shape: vertical 9:16 for Shorts and Reels, square for feeds, or 16:9 for YouTube.
• Style the captions with a preset and export the MP4.

Pick a visualizer that fits the voice

ClipMint has 13 visualizer styles that react to your audio: Particles, Fluid, Soft Fluid, Equalizer, Bars, Mirror, Dots, Radial, Talking Sphere, Voice Bars, Audio Halo, Rings, and Disc. Calm, conversational audio suits Soft Fluid or Audio Halo; music and energetic clips suit Equalizer or Bars; a Talking Sphere gives a voice a presence on screen when there is no face to show. Once you find a look you like, save it as your own preset and reuse it on every episode.

Let the captions carry the clip

• With no face on screen, the words are what people watch, so make them large and high-contrast.
• Keep lines short: fewer words per line reads faster on a phone.
• Use word highlights so the active word lights up as it is spoken.
• Open on the strongest line of the episode, not the introduction.

How the export works

The visualizer is drawn from your audio as the video renders, so audio videos export on your own device, in a desktop browser such as Chrome or Edge. That export is free and has no watermark. You can also download the transcript on its own as SRT, VTT, JSON, or TXT for show notes or a caption track.
