    00:01:14:08The accessibility gap

    Five years to describe everything ever made.

    The EAA enforces full audio-description compliance in 2030. Most streaming back-catalogues are decades behind. Studio production was built for a few hours a year — Synchrogen is built for the rest.

    Drop a master in. Get an editable, validated description track out — voiced, timed and approved — by the end of lunch.

    DESCRIPTION

    What we write. Synthesised in any of fifty languages, voiced by your chosen narrator.

    DIALOGUE · LOCKED

    Source audio. Always wins. Descriptions yield, every time, by design.

    BG MUSIC

    Optionally ducked −12 dB under descriptions to keep narration readable.

    SCENE MARKER

    Cuts, jumps and time-changes — detected automatically, framed for the listener.

    The describer's job has always been to make the invisible audible. Synchrogen doesn't try to replace that — it gives me a first draft I can argue with. Three hours of work where it used to be three weeks.

    00:04:08:12Six voices, fifty languages

    Narrators with a reason for being.

    Each voice is benchmarked against studio talent on intelligibility and immersion — and matched to a job, not a genre. Press play to hear what each one would sound like reading a real take from the editor.

    00:05:42:00The Validation Layer

    Quality is a score, not a promise.

    Every track is scored — automatically, before it reaches you — across the dimensions a senior describer would check. The score ships with the file; so does the audit trail.

    01 ·

    Coverage

    Every significant visual event surfaces in the script. Gaps flagged before delivery, not after.

    02 ·

    Timing & sync

    Descriptions never collide with dialogue. The dialogue track wins, always. Frame-accurate to spec.

    03 ·

    Show, don't tell

    Factual prose. The describer is the camera, not the critic. Inclusive character framing, no editorialising.

    04 ·

    House style

    Third person, present tense, consistent across an entire feature. Validated against a 200k-token style guide.

    Adjust to your catalogue size. Benchmarked against $12/min studio production — the rate most enterprise customers are replacing.

    Same describable minute, two production stacks. The difference shows up on the line item the CFO actually reads.

    For audio description professionals

    Your first draft, ready in minutes.

    Synchrogen is not here to replace audio describers. It is here to eliminate the parts of the job that don't need a storyteller — so the parts that do get your full attention.

    Professional audio description software built around the HITL workflow: AI generates, you approve, the audit trail is yours.

    01 ·

    Skip the blank page.

    Synchrogen generates the first draft — scene by scene, timed to the cut. You open a script that already covers the footage. Your job starts at refinement, not transcription.

    02 ·

    Focus on craft, not clock-watching.

    The easy clips — establishing shots, scene transitions, background action — are handled. Your attention goes to the descriptions that actually need a storyteller: character moments, emotional weight, ambiguity.

    03 ·

    10× your throughput.

    A 24-minute episode that would take 3–4 hours of manual describing is reviewable in under 30 minutes. Same quality bar, same compliance sign-off, your name on the output.

    04 ·

    Every decision is yours.

    Edit any clip inline. Regenerate with a written direction. Approve, reject, rewrite — every keystroke logged to an audit trail. The AI proposes; you decide what ships.

    00:08:12:00Asked by every accessibility lead

    Frequently asked questions.

    01Is this really a working editor, or just a render?+
    Working editor, closed-beta today. Every screen in the platform tour is the real product — you can edit clip text, retime descriptions on the timeline, regenerate with a written direction, split or merge clips, duck dialogue by −12 dB, and compile to a burned-in mix, separate AD track, or WebVTT, exactly as shown. Beta partners are actively using it on shipping projects right now. The distinction matters because Synchrogen is not a prototype — it is a production tool with a review queue, version history, and a compliance audit trail built in from day one.
