    00:01:14:08The workflow problem

    Three tools. Five hours. One 30-minute video.

    Professional audio describers juggle a video editor, an audio editor, and manual spreadsheets. No tool was built for the AD workflow — it was stitched together from generic software.

    Every export, timestamp, and voice pass eats time that should go into the writing. EAA 2030 and CVAA are pushing the industry to scale — manual tool-juggling doesn't.

    For professional audio describers & AD service companies

    Less tool-juggling, more writing time.

    Synchrogen is not here to write your descriptions for you. It is here to remove the parts of the job that don't need a storyteller — finding the gaps, avoiding dialogue, voicing the line — so your attention goes to the writing.

    Every description is written by you, timed by you, approved by you. AI-assisted first drafts are on the roadmap — the tool you get today is a manual editor with the busywork stripped out.

    01 ·

    Know where to write, instantly.

    Scene detection and dialogue transcription find the gaps for you — scene by scene, timed to the cut. You open a script that already knows where every description belongs. No manual timestamp math.

    02 ·

    Dialogue never gets stepped on.

    The transcript is locked in automatically, so your descriptions never collide with a spoken line. Trim, retime, or duck the dialogue track — resolved inline, on the timeline.

    03 ·

    Write once, hear it instantly.

    Type a description and voice it with built-in local narration in seconds — no separate recording pass, no external audio editor, no re-import. Your writing time goes further.

    04 ·

    Every decision is yours.

    Edit any clip inline, split or merge, approve at your own pace — every keystroke logged to an audit trail. You write it, you time it, you decide what ships.

    DESCRIPTION

    What the describer writes. Voiced locally with built-in text-to-speech, in your own words.

    SCENE MARKER

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

    Roadmap

    More voices and languages, coming.

    Additional narrator voices, an expanded language set, and custom voice options are planned next. Today's voicing already covers your typed descriptions out of the box.

    00:05:42:00Built around your standards

    Quality is designed in, not bolted on.

    The editor is built around the standards a senior describer already holds themselves to — dialogue never gets stepped on, nothing gets missed, and every decision is logged.

    01 ·

    Coverage

    Scene and gap detection surface every place a description could go, so nothing gets missed before delivery.

    02 ·

    Timing & sync

    Descriptions never collide with dialogue. The dialogue track wins, always — enforced by the editor, not a checklist.

    03 ·

    Show, don't tell

    The editor stays out of your prose. Factual, third-person description is the standard we design the workflow around.

    Frequently asked questions.

    01Is this really a working editor, or just a render?+
    Working editor, closed-beta today. The platform tour above reflects the real product: you write clip text, retime descriptions on the timeline, split or merge clips, review and approve at your own pace, generate narration with built-in local text-to-speech, and compile to a burned-in mix or a standalone AD-only audio file. 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.
