The carousel is a 16:9 slideshow at the top of a sponsor's booth. Each slide is an uploaded image or an embedded web page, video or stream. Slide views and viewing time are reported in the booth's Traffic Analytics.

Before you start

You need to be an organization admin or an event admin. Sponsor admins can manage the slides of their own booth from Booths.
When the carousel has at least one slide, it replaces the booth's Cover Image.
URL slides must come from sites that allow embedding. See Set up your booth carousel.

Where to find it

Sponsors > Sponsors > [sponsor] > View > Edit Virtual Booth in the admin panel. The Virtual Booth drawer has two lists: Sponsor deck (carousel) and Side bar integrations (slido, etc).

Add a slide

Open Sponsors > Sponsors and select View on the sponsor.
Select Edit Virtual Booth.
Under Sponsor deck (carousel), select New. The Sponsor deck slide drawer opens.
Choose a Slide type: Image (upload) or Embed web page / video / stream (URL).
Enter a Title. The title is shown in the admin panel list and in Traffic Analytics, not to attendees.
For an image, select Image (Aspect ratio: 16:9), choose a file and crop it. For a URL, enter the Url of the embeddable page, starting with https://.
Select Create. Brella shows "Media item added successfully."

Edit, reorder or delete a slide

Each row shows the Title, the Url ("N/A" for images) and an Edit button. Select Edit to change the slide, then select Update. Brella shows "Changes saved successfully."
Drag a row to change the order. Attendees see the slides in this order. The new order saves at once with "Updated successfully."
To delete a slide, select Edit, then Delete, then Delete again under "Are you sure?". Brella shows "Media item deleted successfully."

Slide types

Slide type	What to enter	Limits
Image (upload)	An image, cropped to 16:9 in the upload dialog	"Maximum image size is 5MB." Larger files are rejected with "Image size must be less than 5MB. Current size is <size>MB".
Embed web page / video / stream (URL)	The embed address of a page, video or stream	Must start with `https://` or `http://`; other addresses are rejected with "This field must be a valid url." The host must be a domain name, not an IP address; Brella rejects it with "Url is not a valid URL. Please try again."

An image slide without an image can't be saved: "Please upload an image or delete the record".

What attendees see

The carousel sits at the top of the booth, above the logo and company details. Without slides, the booth shows the Cover Image instead, or nothing.
Slides are 16:9 and follow your order. With more than one slide, attendees swipe or use the arrows on the sides.
Under the carousel, a counter such as "1/3 media" and a Full screen button. In full screen the button reads Close.
Image slides fill the frame. URL slides load inside the slide: the mobile app uses an in-app browser view, the web app an embedded frame. An http:// address is loaded as https://.
On Android, a slide whose address contains .pdf is shown through the Google Docs viewer.
A URL slide loads only when it is on screen. When the attendee leaves the booth, the mobile app pauses video and audio in the slide and the web app unloads it.

Every slide view and the time spent on it are recorded for the booth's Traffic Analytics. The sponsor admin sees them only when Traffic analytics is on for the booth under Edit Details > Booth Control.

Limits

Images: up to 5 MB each, cropped to 16:9.
A site that refuses to be embedded shows a browser error or a blank slide in the web app. The mobile app loads the page as a browser view, not as a frame, so the page loads there.
Carousel views are not leads. Leads come from lead scanning, not from the carousel.
No limit on the number of slides.

Troubleshooting

"This field must be a valid url."
The address is incomplete or has no https:// or http:// in front. Enter a full address such as https://www.youtube.com/embed/<video id>.

A URL slide is blank or shows a browser error in the web app
The site does not allow embedding. Use the site's embed address, or add the page under Side bar integrations (slido, etc) so it opens as a link instead.

The cover image disappeared
The booth has at least one slide. The carousel replaces the cover image. Delete the slides to show the cover image again.
