Reel Driven Development
A reel is a recorded user walk - e.g. a screen-share demo where a domain expert walks through a system while talking. RDD treats the reel as a graph walk:
- every context switch (page, browser tab, application) and every relevant interaction (submenu, filter, zoom, sort) is a hop
- the narrative drives the sampling, never the clock
- every hop gets an evidence frame (screenshot) or a proven-absent note
- findings become outcome objects: a frustration spoken during a walk becomes a bug report, which is an acceptance criterion, which is an example
The first tooling milestone is HopDetection - see issue #1.
Example: GenWiki walk
Acceptance run on the test video segment 20:00-21:00 - a walk through wiki.genealogy.net category pages:
hopdetect ~/.rdd/cache/gVxk-zRb0wQ.mp4 --start 20:00 --end 21:00 --out hops
12 hops from 786 sampled frames -> hops/hops.json
Raw results in examples/genwiki-walk. Of the 12 detected hops, 9 are distinct content states of the walk (hop numbers kept as in hops.json):
| hop | time | changes grouped | content | frame |
|---|---|---|---|---|
| hop01 | 20:02 | 32 | Kategorie:PDF |  |
| hop02 | 20:06 | 11 | Kategorie:PDF, media section |  |
| hop03 | 20:10 | 24 | file page with PDF viewer (Todfall-Rodel Kloster Salem) |  |
| hop04 | 20:20 | 94 | presentation slide with category links |  |
| hop05 | 20:28 | 57 | Kategorie:Icons, media section |  |
| hop06 | 20:34 | 40 | Kategorie:Icons |  |
| hop07 | 20:37 | 2 | Kategorie:Portal icons |  |
| hop10 | 20:47 | 2 | presentation slide revisited |  |
| hop12 | 20:59 | 73 | Kategorie:SVG, flags gallery |  |
False positives
Three detections are not content states of the walk - kept in the example as tool findings:
| hop | time | reason |
|---|---|---|
| hop08 | 20:41 | cursor-motion burst on the unchanged Kategorie:Portal icons page |
| hop09 | 20:45 | transient browser tab-hover preview overlay, page unchanged |
| hop11 | 20:50 | blank frame: Kategorie:SVG captured before rendering; the settled state is hop12 |
