The Car Production
How a video gets made
The Car Veteran is produced by one person with an in-house publishing tool. The tool handles the repetitive parts — drafting, voicing, timing, rendering, uploading — so the work is a review step rather than an afternoon of editing.
The pipeline
- Write the exchange One maintenance topic, written as a short back-and-forth: Sparky asks, Rusty explains, and the last line lands on the practical takeaway. Runs 30–60 seconds when read aloud.
- Voice both characters Each character is read by its own synthetic voice, at its own speaking rate, so the two are distinguishable by ear alone. The voice engine also returns per-word timings used in the next step.
- Time the captions Those word timings are turned into a caption track, so the on-screen text lands exactly with the narration rather than drifting.
- Assemble the video ffmpeg composites the dialogue audio, the caption track, the two character portraits — each kept to a fixed side of the frame — and looping car footage into a 1080×1920 vertical video at 30fps.
- Review The finished file is held for approval before anything is published. Nothing is released without a person looking at it.
- Publish Approved videos are uploaded to the channel's own accounts, with a per-platform caption, hashtags and any footage credit the licence requires. Every attempt — success or failure — is logged.
The footage
Backgrounds are driving clips kept in a local library and cut into short segments so no two videos look identical. They come from two places: footage recorded by the operator, and clips published by others under a Creative Commons licence. Licensed clips are tracked with their source alongside the footage and credited in the video description, as that licence requires.
The footage is visual accompaniment chosen to hold attention on a phone screen; the advice carries the video.
Rate limits and safeguards
The tool is deliberately conservative. It produces at most one video per scheduled run, enforces a daily publishing ceiling per platform, refuses to publish two videos under the same story title, and stops and logs on any API failure instead of retrying in a loop.
| Guardrail | Behaviour |
|---|---|
| One video per run | A scheduled run produces a single video, never a batch. |
| Daily ceiling | Publishing stops before the platform's quota is reached. |
| No duplicate titles | The same story is never published twice. |
| Fail closed | An API error is logged and the run stops — no retry storms. |
| Human review | Finished videos are approved before release. |
Content standards
The tool will not produce, and the channel does not publish:
- Content depicting or naming real people.
- Content that sexualises or targets minors.
- Named accusations against a particular garage, dealership or brand. Videos describe practices, not businesses.
- Instructions for work that is unsafe to attempt without training — anything involving brakes, steering, airbags or fuel is explained, then handed to a qualified mechanic.
The characters are fictional and the voices are synthetic. The advice is general: it describes how a repair or a quote usually works, not what is wrong with any particular car.
