Why make a video from audio
YouTube, Instagram, TikTok and many messaging apps accept video but not a bare audio file, and almost none of them accept OGG. When you convert OGG to MP4, you get a normal video file with your sound and a picture. It is the simplest way to publish a song, a game soundtrack, a podcast clip or a recording of your band on a video platform.
Choosing the picture
- Your own image – album art, a photo or a title card. Use an image at least as large as the video size.
- Plain colour – clean and quick, good for speech.
- Gradient – two colours of your choice when you have no artwork.
- Animated waveform or spectrum – moves with the sound and makes a static video feel alive.
Picking the right size
| Format | Best for |
|---|---|
| 1080p (1920×1080) | YouTube, sharp on large screens |
| 720p (1280×720) | Faster rendering, smaller files |
| Square (1:1) | Instagram and Facebook feeds |
| Vertical (9:16) | Stories, Reels, Shorts and TikTok |
Good to know
The video is created in your browser, so rendering speed depends on your computer and the length of the audio. A short clip takes moments; a one-hour recording takes longer, especially with an animated waveform. A still picture keeps the file small, because the video encoder has little to store between frames.
The OGG audio is re-encoded for the MP4 file. Social platforms compress uploads again anyway, so start from the best OGG you have. For very long material, consider cutting a highlight with Cut first, since many platforms limit the length of short videos. If you want more control over the look, the full Audio to Video tool offers the same options for any audio format, and OGG to MP3 is there if you only need a widely playable audio file.
