Rich-media actions accept file uploads (images, video) or embed video players. They’re used for user-generated content (UGC) challenges, moderation-gated submissions, and video-driven experiences.Documentation Index

Action types
Image Upload
Members upload a photo to complete the action. Admin reviews in the Review Achievement Flow queue.- Compression to WebP happens on upload (#778) — storage + bandwidth optimisation, transparent to admins.
- Strict aspect ratio enforcement (#828): choose a fixed ratio so all submissions fit the member gallery layout. Cropping is rounded (#811) so images look intentional, not cut.
- Banner upload above the action (#647) for context.
- Image upload reporting (#1504) tracks success/failure rates per action.
- Re-upload after failure works cleanly (#1853) — members can retry without losing their form state.
The legacy “image disclaimer” modal was removed (#740). If you need member consent, use the community rules / agreement checkbox pattern instead.
Video Action
Embed a video into the action and require a completion signal (watched to end, specific timestamp hit). See Video Challenges for the purpose-built admin UI (#1138, #944, #1076, #1114).Object Detection
Members upload a photo and the action passes only if the AI detects a specific object class (e.g. “dog”, “product barcode”). Backwards compatibility for existing object-detection configs was added in #846 — your old detection rules keep working after the refactor.Aspect ratio picker
When you create an image-upload action, pick a fixed ratio:| Ratio | Use case |
|---|---|
| 1:1 square | Profile-style submissions, social amplification |
| 10:4 banner | Community banner submissions |
| 16:9 landscape | Video stills, widescreen content |
| 4:5 portrait | Instagram-style mobile feed |
Image reporting
The admin view for each rich-media action shows:- Submissions count (success vs. failed upload)
- Review queue size (if moderation is on)
- CSV export of raw submissions
- Per-member thumbnail gallery
