B-roll Auto-fill & Shoot List

When a template has several image slots — hero shot, product photo, lifestyle, etc. — filling them by hand for every carousel gets tedious. The B-roll system fixes this by matching slots to tagged photos in your library.

The Three Pieces

• B-Roll Labels — tags attached to image layers (and, optionally, slide backgrounds) inside a template.
• B-roll library — your uploaded photos and clips, each tagged with one or more labels. Managed in Settings → B-roll.
• B-roll panel — the auto-fill UI in the editor. Lists every tagged slot in the carousel, shows matching files from your library, and offers a one-click bulk fill.

Tagging Image Slots (template authoring)

Adding labels to image layers happens in template-editing mode. With a template open in that mode, hover an image layer in the layers list — a Tag icon appears next to the lock icon. Its tooltip reads Add B-Roll labels (or B-Roll labels: … if labels are already set). Click it to open the B-Roll Labels popover.

Inside the popover:

1. Type a label and press Enter to add it as a chip.
2. As you type, an autocomplete dropdown suggests existing labels pulled from across all templates (previously used labels also appear as quick-add chips beneath the input, with a count showing how many templates already use each one).
3. Click the × on a chip to remove a label. Any layer can carry multiple labels — a slot matches if any of its labels matches a library item.

Tip: Use consistent, descriptive labels across templates (for example, "gym-action", "product-flatlay", "speaker-on-stage"). Reusing labels is what makes auto-fill work across projects.

Background images

Slides can also carry their own background labels (backgroundBrollLabels on the slide). These are edited from the Template Settings dialog (B-roll tab), not from the regular layers panel. The label UI is the same — same chip input, same autocomplete — it just writes to the slide background instead of a layer.

Managing Your B-roll Library

The library itself lives in Settings → B-roll. The B-roll panel in the editor has a Manage B-roll library link at the bottom and on the empty state that opens it directly. Upload photos (or short clips), tag each one with the same labels you use in your templates, and they will start matching automatically.

Auto-Filling from the B-roll Panel

Open the B-roll panel from the left sidebar (B-roll button with the film icon). The panel lists every tagged slot in the current carousel — image layers first, then any slide backgrounds whose backgrounds are editable.

Each row shows the slot thumbnail, the layer/background name, its labels, and one of:

• A wand button with a small badge if the slot has multiple matching files (e.g. "3"), or just the wand if there is exactly one match.
• A dimmed wand with the tooltip No matching B-roll — add one in Settings → B-roll when no library item matches any of the slot's labels.

Filling slots

1. Auto-fill all (the big button at the top of the panel) — fills every slot that has at least one match. When a slot has more than one matching file, a random one is picked. A toast confirms how many slots were filled.
2. Click the wand on a single slot to fill just that one. If there is exactly one match the file is applied immediately. If there is more than one, the Choose B-roll dialog opens with a grid of options so you can pick which file to use.

What B-roll Auto-Fill Will Not Touch

• Image slots that have no B-Roll labels — they stay manual.
• Slide backgrounds whose backgrounds are not marked editable (only the basic editor's Background Image Editable setting unlocks them).
• Text, colors, shapes, icons — B-roll only swaps the URL of image slots and slide backgrounds.

Note: Bracket Tag Fills (replacing tokens like [Name], [Business], [Niche] in text layers) is a separate, text-only feature from your profile data. It is not part of the B-roll system.
