@ -112,6 +112,33 @@ The demo scene itself is `src/arthur/demo/scene.edn`. Both the synthetic take
and real footage use `src/arthur/flow/take.cljs` for the measurement order and
`src/arthur/flow/freeze.cljs` for the landmark-to-channel conversion.
**stage 8625** loads the locally saved `IMG_8625.MOV` project and places its
post-processed timeline twice. The stage layout is
`src/arthur/demo/stage_8625.edn`: the right picture and sound start at frame 48,
and the two pictures overlap slightly in stage space. Audio has its own timeline
nodes, linked to the picture instances but with independent spans and gain
channels. The right sound swells and pans across the stage, then fades out at
frame 260 while its picture continues to
frame 280. The button needs that saved 8625 project in the local server database.
### Projects and the EDN fixtures
The EDN files under `demo/` are authored examples compiled into the frontend.
They seed a clip in memory; the server does not read EDN. Clicking **save** on a
clip without a project id creates a project through `POST /api/projects`, uploads
any missing content-addressed blocks, then writes the clip's addressed leaves
through `PUT /api/projects/<id>`. Each leaf value is Transit JSON inside the
request's ordinary JSON envelope. Python stores those values in JSON columns and
does not need an EDN parser. **open** reads the leaves and blocks and rebuilds
the same ClojureScript clip.
The intended editor creates and changes that in-memory clip directly: a project
browser and **new stage** action, timeline instance placement, node and channel
editors, then the existing save path. EDN remains useful for checked-in examples
and reproducible studies. The current UI has save and open, but no project
browser, blank-stage action, or authoring controls yet; open chooses the most
recent project.
### Real footage
Choose a video in the **footage** file input. The server probes it, re-encodes it
