Uploading music and artwork
Which audio and image files LimePulse accepts, how long a track can be, what makes good cover art for a moving video, and how uploads are reused across projects.
Every studio starts with a file you own. Here is what is accepted, and what makes the result look better.
Which audio formats are supported?
| Format | Supported | Notes |
|---|---|---|
| MP3 | Yes | The most common upload. Any bitrate |
| WAV | Yes | Best quality, largest file |
| M4A, AAC, OGG and FLAC | Convert first | Export a WAV or MP3 instead |
Mono and stereo are both fine, up to 200 MB. In the finished video the soundtrack is encoded as AAC at 192 kbps, the standard audio for an MP4, made from the file you uploaded. Upload your best master and the video carries the best version of it.
How long can a track be?
A song can run from 30 seconds to 10 minutes, and the video runs the whole file. A podcast episode can run up to 3 hours. A Spotify Canvas loop is deliberately short at 8 seconds, because Spotify's own guidelines put a Canvas at 3 to 8 seconds.
Which image formats are supported?
- PNG, including transparency
- JPEG
- GIF, though only its first frame is used in a render
- Up to 20 MB each. WebP is not accepted: save it as PNG or JPEG first
What makes good cover art for a video?
Artwork that looks great as a thumbnail does not always look great moving. A few things help:
- Square and at least 1000 x 1000 pixels, so it stays sharp when a template scales it up
- A clear focal point, because many templates crop or rotate the art
- Enough contrast that text placed over it stays readable
- Avoid artwork that already contains a border or a frame, which fights the template's own framing
There is more on this in how to pick cover art that looks great in motion.
Do I need cover art at all?
No. Some templates are built around type and motion rather than a picture, and Compose, the visualizer builder, can compose a frame with no artwork in it. If you want art but do not have any, the plan includes 200 AI-generated covers a month, described in plans and pricing.
Are my uploads reused between projects?
Yes. Anything you upload lands in your library, so the same track or cover can be pulled into another project without uploading it again. Deleting an upload from the library removes it everywhere.
