Showfile

Free browser tools for live production, served at https://showfile.ericdahl.dev:

• Console Scene Converter (/convert/): moves a show between the Behringer X32 / Midas M32, X Air / Midas MR and Behringer Wing, in any direction.
• LTC Timecode Generator (/timecode-generator/): SMPTE LTC WAV files at any frame rate, one file or a batch in a zip.

Both run entirely in the browser. There is no build step, no backend and no analytics: each page is static HTML that loads plain ES modules from js/.

Develop

npm run dev     # http://localhost:8080/convert/ and /timecode-generator/
npm test        # node --test, no dependencies

Pages use root-absolute paths (/js/, /css/, /fonts/), so open them through the dev server, not from file://. npm run dev needs python3, and so does the zip test, which checks archives with Python's zipfile.

Layout

Path	What it is
convert/index.html	Converter page
timecode-generator/index.html	LTC generator page (its UI script is inline)
js/x32-scene.js, js/xair-scene.js, js/wing-scene.js	Readers: desk file → neutral IR
js/x32-emit.js, js/xair-emit.js, js/wing-snap.js	Writers: IR → desk file
js/console-map.js	Color and icon mapping between desks
js/losses.js	The graded "check these on the desk" report
js/scene-text.js	Shared .scn tokenizing
js/convert.js	Converter page UI
js/ltc.js, js/zip.js	LTC encoder and the zip writer for batch export
js/ltc-batch.js	LTC batch plan: file names, timecode spans, limits, sizes, manifest
js/nav-tools.js, js/version-tag.js, css/brand.css, fonts/	Shared chrome
favicon.svg	The mark (a fresnel, head-on); also the logo in the lockup. PNG icons are rendered from it
css/brand.css	Every color and font token, the stage-wash background and the logo lockup
index.html	Home page listing the tools
og/index.html	Source for the share images (not linked from the site)

Testing on a desk

test/desk-pack/ holds each real fixture converted to every other desk, with a checklist (test/desk-pack/README.md) of what to look for when loading it: on an XR18 through X-AIR-Edit, or offline in X32-Edit and WING-EDIT. Regenerate with npm run desk-pack; the tests fail if the pack no longer matches the converter.

Share images

og-image.jpg, og-image-convert.jpg and og-image-timecode.jpg are screenshots of og/index.html, which is kept as their source. To regenerate one after a copy or brand change:

1. npm run dev
2. Open http://localhost:8080/og/?page=home (or convert, timecode) with the browser viewport at exactly 1200×630 and a device pixel ratio of 1. In Chrome DevTools, use device toolbar, Responsive, 1200 × 630.
3. Capture the viewport as JPEG and save it over the matching file at the site root.

The timecode waveform is drawn from js/ltc.js, so it is real LTC for 01:00:00;00.

Tests and their limits

test/fixtures/real/ holds real scene files off an X32, an X Air and a Wing (see its SOURCES.md); the tests read each one and convert it to both other desks. test/fixtures/synthetic-x32.scn is hand-written, for cases the real files don't cover. Passing tests still don't prove a console loads the output: that needs a round trip through the desk or its editor.

History

The first commit is the site exactly as stagebuilderpro.com served it on 2026-09-24 (APP_VERSION 2.6), recovered because the original source repo was not available. The tools began as part of StageBuilder Pro and were split out as Showfile on the same day, with their own name, mark and domain. Releases: v1.0.0 is that untouched snapshot; v2.0.0 is Showfile with the Stage Wash redesign.
