Use Creative Hub files in Campaign Creator

From any campaign in /campaign-creator/new (PRD-15 Campaign Creator), the creative block has a Browse Creative Hub button. Pick image / video → injected into the ad spec as a reference (no duplication). The picker filters by type, searches by name, and surfaces recently used items first.

Who is this for

Mediabuyers launching campaigns who don't want to re-upload assets they've already stored in Creative Hub.

The flow

Step 1: Open Campaign Creator

/campaign-creator/new (Express or Pro mode) → reach the creative block (per cc-110).

Step 2: Click "Browse Creative Hub"

In the creative block, alongside Upload / AI generate buttons, click Browse Creative Hub.

Step 3: Pick from the modal

A file picker modal opens:

• Filter by type: All / Images / Videos
• Search by name (debounced)
• Recently used chips above the grid (last 10 you used)
• Folder navigation (default = root; navigate into folders)

Click a file → preview pane on the right → Select button confirms.

Step 4: File appears in ad spec

The selected file is injected as a reference in the ad's creative spec. UI shows the thumbnail + name. Replace anytime by clicking again.

What "reference" means

The file is not duplicated to a campaign-specific folder. The ad spec stores a reference to the file's Drive id (there is no creative_hub_file DB table — files live on Drive). If you later delete the file in Creative Hub, the ad's reference may break.

Implications:

• Don't delete Creative Hub files used by active campaigns — breaks ad serving
• Rename in Creative Hub propagates to the reference (name is read live)
• Move within Creative Hub is safe (id stays stable)
• Archive old creatives in a _archive folder instead of deleting

Multi-creative ads

For ads with multiple creatives (carousel, slideshow):

• Pick one Creative Hub file per slide / card
• Or mix Creative Hub picks with new uploads in the same ad
• Drag-reorder within the ad spec

Picker filters

The picker respects your Creative Hub RBAC: you see only files you have visibility on (see ch-127).

Recently used surfacing

Above the grid, chips show the last 10 Creative Hub files you used in any campaign. Click chip → instant select. Reduces clicks on the most common workflow ("re-use winning creative across new campaigns").

Use cases

Reuse winner across multiple campaigns

Won creative on Campaign A → use it on Campaign B (new audience, same creative). Picker → recently used chips → 1-click select.

A/B test multiple creatives

Build 3 campaigns with same audience + 3 different creatives from Creative Hub. Picker speeds it.

Mix AI-generated + uploaded

Use Creative Hub-generated image as background + uploaded logo as overlay → combine via Compositing (ch-117) → use composite in campaign.

Agency template fill

Agency: brand assets in Creative Hub team folder. Each new client campaign: picker → brand assets folder → pick the right variant.

Limits

• Picker pagination: 50 files per page, infinite scroll
• Picker search debounce: 300ms; type then wait briefly
• Recently used cap: 10 chips (per user per session)
• No bulk select in picker: pick one at a time (use individual ad-spec slots for multi)

Common mistakes

• Deleting a Creative Hub file referenced by active campaign: campaign serves broken creative. Archive instead.
• Expecting picker to upload new files: picker is for existing Creative Hub files only. Use the Upload button in the creative block to add new.
• Forgetting recently used: if you scrolled past recently used chips, you do more clicks than needed.
• Picking from wrong member's folder: RBAC limits what you see, but if your team uses shared folders, double-check the file is the right version.

FAQ

Does picking a Creative Hub file duplicate it into my campaign?

No. When you select a file through Browse Creative Hub in the Wevion Campaign Creator, it is injected into the ad's creative spec as a reference, not a copy. The ad spec stores a pointer to the file's Drive id (there is no creative_hub_file DB table; files live on Drive), so the same asset can be reused across many campaigns without duplication.

What happens if I delete a Creative Hub file used by an active campaign?

Deleting it breaks ad serving, because the campaign's creative spec still references that file. Wevion recommends archiving old creatives in an _archive folder instead of deleting them. Moving a file within Creative Hub is safe (the id stays stable), and renaming it propagates to the reference since the name is read live.

Can I upload a new file from the Browse Creative Hub picker?

No. The picker is for existing Creative Hub files only. To add a new asset, use the Upload button in the creative block instead. Inside the picker you can filter by type (All / Images / Videos), search by name, navigate folders, and click a recently-used chip to select one of the last 10 files you used.

How do the recently used chips speed up my workflow?

The chips above the picker grid show the last 10 Creative Hub files you used in any campaign, letting you re-select a winning creative in one click. This targets the common workflow of reusing a winning creative across new campaigns — for example applying Campaign A's winner to Campaign B with a new audience.
