Media Library
The Media Library holds your channel's videos and images. Everything your channel plays from files comes from here: playlists, scheduled broadcasts, program episodes and commercials. So do the images for your channel icon, poster and show banner.
Open the Media Library
In the channel menu, click Media Library.
- Header: how many videos and images you have, and the Upload Media button.
- Storage bar: how much of your storage allowance is used and what's using it. It also offers to free up old recordings.
- Tabs: Videos and Images, each with its count.
- Clips: one card per clip. Click a card to open its preview. Use Show … items per page at the bottom to show 20, 50 or 100 at a time.
What You Can Upload
| Type | Formats | Largest file |
|---|---|---|
| Video | MP4, MOV, AVI, MKV | 2 GB |
| Image | JPG, JPEG, PNG, WEBP | 2 GB |
Recordings of your live broadcasts are added to the library automatically. Their cards say Recording instead of Upload. See How do I Record My Broadcasts?.
How Videos Are Processed
Every video is processed before it can be used. Images are ready as soon as they're uploaded.
| Stage | What happens |
|---|---|
| QUEUED | The video is waiting for the encoder. Your channel processes one video at a time, so others wait their turn |
| CONVERTING | The video is rewritten in the broadcast format your channel plays |
| BUILDING PREVIEW | It's cut into segments, so it can play in the library and in Catchup |
| PACKAGING | It's encoded at each of your channel's output resolutions, so it can go to air without a live encoder |
While a video is processing, its card shows the stage and a percentage. Processing usually takes a few minutes, depending on the file's size, and long recordings can take several hours. It carries on if you leave the page.
When processing finishes, the card shows Ready. If your browser allows notifications from Cecula Stream, you also get a Transcoding Successful or Transcoding Failed notification. You're emailed if processing fails.
Clip Statuses
| Status | What it means | What to do |
|---|---|---|
| Ready | Processed and ready to use | Nothing |
| Queued | Waiting for the encoder | Wait |
| Processing | Being processed. The card shows the stage and percentage | Wait |
| Stalled | Processing stopped unexpectedly | Click Restart on the card |
| Out of Space | Saved, but not processed, because the channel didn't have enough storage | Free up space or add storage, then click Start encoding |
| Failed | Processing failed. The card shows the reason | See If Processing Fails or Stops |
Warnings on a Clip
| Card shows | What it means | What to do |
|---|---|---|
| Resolution Too Low | The video is smaller than the lowest output resolution your channel broadcasts, so it can't be used on this channel. Re-encoding can't fix this | Upload a higher-resolution copy, or switch on a lower resolution under Stream Output Resolutions if your plan offers one |
| Needs Re-encoding | The video isn't prepared for your channel's current output resolutions, or doesn't carry your channel's current watermark | Open the clip and re-encode it. See Re-encode a Clip |
| … parts deleted | Parts of the clip were deleted to free up space | Re-encode the clip to rebuild them, if its original is still there |
Clips that can't be used on your channel aren't offered when you pick videos for playlists and schedules.

Media and Storage
Each video uses more storage than the file you uploaded: the original, its streaming versions at several qualities, a working copy for re-processing and, if you make one, an MP4 download. Together these come to several times the upload.
Open a clip to see how much storage it uses and what for. See How do I Manage Channel Storage?.
When the channel is nearly out of storage, Upload Media is disabled, with a note on how much is left.
Who Can Use the Media Library
Owners, administrators and editors can upload, edit, split, clean up, download and delete media. Viewers can browse and preview, but can't change anything. See Roles.
