The answer should come from the shape of the work, not from whichever button is most visible. ## Who Should Read This | Reader | Use this page to | | ----------------------- | ------------------------------------------------------------------- | | New user | Choose the first Redbit module for a task | | Creative operator | Decide when to move from one-off generation into Series or Workshop | | Support or success team | Triage a confused workflow without overstating product capabilities | ## Before You Choose Confirm the media type, provider route, reference inputs, and review owner. If the task involves sensitive media, read [Security and Credentials](./security-credentials.mdx) before uploading or routing source material. ## Capability Selector The SVG below is a capability selector. Use it during onboarding or support calls to map user intent to the smallest Redbit surface that can complete the job. Capability selector diagram showing how Redbit work routes to Cards, Series, Workshop, Agent, Seedance, or Model Registry. ## Matrix | Surface | Use when | Avoid when | Typical output | | --------------------------- | ---------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------- | | Cards | The job is one independent image, video, audio, speech, or describe task | The work has many scenes, scripts, or export stages | Card results, downloads, reusable references | | Series | One image prompt should become a planned set of 3, 4, 6, or 8 related images | Each image needs unrelated prompts or separate review rules | Slot briefs, editable prompts, reviewed image set | | Workshop | The job has project structure: script, scenes, consistency references, media stages, voiceover, music, or export | The task is only one prompt and one output | Project state, scene media, voice/music assets, export package where configured | | Agent | The request spans several explicit Redbit actions and can be checked in the workspace | The task is credential entry, billing, visual judgement, ambiguous deletion, or unreviewed external effect | Created or updated Cards, assets, Workshop changes, tool results | | Seedance | The video task needs text-to-video, image-to-video, first/last-frame, or multi-reference roles | The selected provider route does not support the Seedance variant or required input roles | Video card result with mode-specific references | | Model Registry and Settings | The question is model visibility, provider route, relay capability, variant, ratio, duration, or Agent runtime profile | The user only needs to compare generated media visually | Confirmed provider setup, model selection, capability test result | ## Quick Questions | Ask | If yes | | ------------------------------------------------------------------------- | ---------------------------------- | | Does the work need only one inspectable task unit? | Start with Cards | | Does one prompt need a repeatable image set? | Use Series | | Does the work have script, scene, or export structure? | Use Workshop | | Does the user want multiple explicit UI actions? | Use Agent after confirming targets | | Does the video depend on first frame, last frame, or multiple references? | Use Seedance-specific workflow | | Is the issue about a missing model or failed provider route? | Check Model Registry and Settings | ## Handoff Rules | Situation | Minimum handoff artifact | | ------------------------ | ----------------------------------------------------------------------------------- | | Card-only exploration | Selected cards, prompt notes, model and variant, downloads or pinned assets | | Series output | Base prompt, template, slot prompts, selected outputs, rejected outputs if useful | | Workshop project | Project name, scenes, selected source images, generated clips, export settings | | Agent-assisted task | Original request, tool actions, visible workspace changes, unresolved confirmations | | Provider troubleshooting | Route, model family, variant, error message, relay setting, provider console status | ## Next Step Use [First Project Walkthrough](./first-project-walkthrough.mdx) to apply the matrix in a real flow, or [Troubleshooting Playbook](./troubleshooting.mdx) when the chosen surface does not complete successfully.
