From PR to Video: What Actually Happens

You merge a pull request. A few minutes later, Diffvideo has a branded video ready for you to review or share. If you have never used the product, that gap between "git event" and "MP4 in my inbox" can feel like magic. It is not magic. It is a small number of user-visible steps that repeat reliably.

What Diffvideo needs from your repository

Diffvideo reads the same signals a good release note would use: what files changed, what the commits say, and (most importantly) what the pull request title and description claim happened. When that context is thin, the output is thinner. When it is rich, the output is specific and confident.

That is the practical lesson for teams: the product can only amplify what the repository already contains. A two-sentence PR description that explains intent beats a wall of diff noise with no narrative.

What you see as a user

Depending on your settings, Diffvideo either creates a suggestion you approve before render, or moves straight to a finished render. In suggest mode, you can tighten wording, change the video type, or reject a suggestion entirely. Nothing publishes until you are comfortable with it.

When a render completes, you get a shareable link and an MP4 you can download. Branding (colors, logo, typography) comes from what you configure in Diffvideo, so the file reads like your product, not a generic template dump.

What "fast" means in practice

Most teams see end-to-end turnaround on the order of a few minutes for typical changes. Very large diffs or long videos take longer, but the goal is the same: something watchable should land quickly enough that it still matches the moment when the team cares about the change.

Why this matters

If you are evaluating Diffvideo, do not judge it on whether it can narrate every line of code. Judge it on whether it turns routine shipping into routine communication: fewer "what shipped?" threads, fewer stale changelogs, fewer one-off Looms.
