For digital signage, make images 1920 x 1080 pixels (1080 x 1920 for a portrait screen) as JPG or PNG, and videos 1920 x 1080 MP4 files with H.264 video at 30 frames per second or less. Those play smoothly on every common player. Upload them to your signage software's media library, then add them to a playlist or put them on a screen.
In Brix, open Files in the Content group of the sidebar, select Upload and drop the file in. Files holds every image, video, PDF, PowerPoint file and HTML5 package (.zip) your screens play. Every member of a Space can browse it; upload, move and delete each need their own permission.
Best image and video size for digital signage
| Make it | What Brix does with other files | |
|---|---|---|
| Image | 1920 x 1080 (landscape) or 1080 x 1920 (portrait), JPG or PNG | An image larger than 2560 pixels on its long edge is resized before upload. |
| Video | MP4, H.264, 1920 x 1080, 30 fps or less | Brix converts other files to that format after the upload: iPhone HEVC, .mov, 4K, 60 fps, or a bitrate over 16 Mbps. It takes a few minutes. |
| Aspect ratio | The same shape as the screen: 16:9 or 9:16 | A file of another shape is fitted to the screen. Make it the right shape to avoid bars or cropping. |
Do not upload 4K for signage. A 4K file takes longer to download to every screen, and 4K video can stutter on low-cost players such as the Amazon Signage Stick, so Brix converts it to 1080p anyway.
Upload images and videos
- Open Files and select Upload in the topbar.
- Drop your files onto the dashed area, or select the area to open the file picker.
- Wait for each staged row to show its thumbnail and dimensions.
- Change the name or add tags in the boxes on a row if you want. Select the X on a row to drop it.
- Choose a destination in the Folder dropdown at the bottom left. One folder applies to the whole batch.
- Select Upload.

To import from a web address instead, paste it into the import box under the drop area and select Import. Videos upload as they are, and Brix prepares each one for screens afterwards, which can take a few minutes.
To generate captions on upload, tick Auto-generate captions under a video row and leave the page open. When your Space needs alt text, Upload stays inactive until every image has a description or a Decorative tick.
Find a file in the library
- Type a name or a tag into the search box.
- Select All, Images, Videos, Files or Apps to narrow by kind.
- Use the Type and State dropdowns to narrow further, for example In use or Unused, or a processing state such as Ready, Processing or Expired.
- Switch between Grid view and List view at the right of the filter bar.
- Select Clear search and filters when the view reports no matches.

Fonts do not appear in Files. They live in the Brand Kit.
Organize files in folders
- Select New at the top of the Folders rail, type a name and press Enter.
- Tick one or more files.
- Drag them over the Folders rail and release on the destination folder. Or select Move to… in the bar at the bottom, pick a folder and select Move.
Select a folder in the rail to see only its files, and All to see everything. Hover a folder row for the pencil (rename) and bin (delete) buttons. A folder only organizes the library and does not change where a file plays. A deleted folder does not go to the recycle bin. Folder changes need edit or create permission.
Open a file
Select a file card or row to open its detail panel.
- Rename: select the name at the top, type, press Enter.
- See where it plays: read the Used by row and select See where to list the playlists, schedules, layouts and templates that use it.
- Pause it: turn Active off. A paused file plays in no playlist or schedule until you turn it back on.
- Download the original: select Download at the bottom. A link has no file to download.

Set an expiry date so old promotions take themselves down
- Select the file and expand Validity in the detail panel.
- Pick a date and time under Show from to keep the file hidden until then.
- Pick a date and time under Expires to stop it playing after then.
- Tick Move to recycle bin when it expires to archive the file for you.

Leave a field empty for no limit. An expired file stays in the library with an Expired pill unless you ticked the archive box. To list expired files, choose Expired in the State dropdown.
Sound and captions for a video
A video plays with no sound by default. Select the video, then:
- Turn the Sound switch on. Each screen keeps its own volume, so a muted screen stays silent.
- Turn the Captions switch on. If the video has no caption track, Brix transcribes the audio. To use your own, select Upload file in the Captions row and choose a .vtt or .srt file. A video with no audio track cannot carry captions.
Delete and restore files
- Select the file and select Delete. To delete several, tick them and select Delete in the bar at the bottom.
- If the file is in use, read the figures in the Move to recycle bin? dialog, then confirm.
- Select Undo in the message at the bottom of the page to bring it back straight away.
A file nothing uses goes to the recycle bin with no confirm dialog, only the Undo message. To clear files nothing points at, select Unused at the bottom of the Folders rail and Delete all.
To restore later, select Recycle bin in the topbar and Restore on the row. Brix deletes everything in the recycle bin 30 days after you remove it. Purge now and Delete forever cannot be undone.

Next, build a loop from your files in playlists.
