Frequently asked questions
Why turn audio into video?
Instagram, TikTok, YouTube and X accept video, not audio files. A waveform video lets you share a song, podcast clip or voice note anywhere.
How long can the audio be?
There is no fixed limit, but rendering takes roughly as long as the audio on a recent computer. For social posts, cut a short highlight first with Audio Cutter.
Can I add subtitles?
Yes. Make the video here, generate subtitles with Auto Subtitles, then burn them in with Burn Subtitles.
Is my audio uploaded?
No. The video is created with FFmpeg running in your browser.
What if I choose None for the waveform?
You get a still video of your cover image or background colour with the audio, which is the smallest and fastest option.
Does it work on phones?
Yes. Short clips render comfortably on phones; long ones take more time.
