Chapter 2 — Generate a Workflow

Your first hands-on chapter. By the end, you'll be able to take an existing workflow file (.nbflow) and produce finished videos from it — no scripting, no prompt writing, just running and reviewing.

This is the easiest task in the pipeline. Get comfortable here before moving to variants and creating from scratch.

What you'll learn

  • How to start the G-Labs backend and a cloudflared tunnel
  • How to load an existing .nbflow file into PatchWork
  • How to run the Generation Runner
  • How to review candidates in PatchWork and pick the best ones
  • How to rerun individual nodes when something didn't land
  • How to handle B-roll (which runs separately from the main .nbflow)
  • How to export final assets for post-production

Before this chapter

Read Chapter 1 — Foundations. You should know what a workflow is, what a prompt is, what PatchWork is, and who the agents are before starting here.

Sections

  1. Setup & per-session checklist — get G-Labs and the tunnel running
  2. G-Labs + cloudflared — the local backend and tunnel in detail
  3. PatchWork overview — the tool you'll be using
  4. PatchWork node types — every node type you'll see
  5. Running a workflow manually through PatchWork — click through the graph node by node
  6. Reviewing in PatchWork — pick candidates, navigate tabs
  7. Rerunning failed nodes — re-roll seeds, edit prompts, single-node reruns
  8. Manual B-roll generation — B-roll runs separately from the .nbflow
  9. Exporting final assets — handoff to post-production

Automation comes later

Once you understand manual generation, Chapter 12 introduces the Generation Runner agent — the automated executor that does all of this in one shot. Learn manual first; automation will make sense after.

When you're ready

→ Next: Chapter 3 — Lvl 1-2 Variants. Take a finished workflow and produce a variation of it — a dialogue swap or a wardrobe change. Low risk, auto-approved.
