How to Record a Bug Report Developers Will Actually Understand

Short version: The best bug report is a short screen recording where you reproduce the problem from the start, narrate what you expected versus what happened, and mention your browser/app version and OS. That gives a developer everything they need to recreate and fix it — no follow-up thread required.

Every developer has received the bug report that says “the button doesn’t work.” Which button? On what page? What did you click first? What did you expect? Cue three days of back-and-forth. A 90-second screen recording ends all of that. Here’s how to make one that gets your bug fixed on the first try.

Why video wins

A screenshot freezes one moment. But most bugs are a sequence — you did this, then that, and then it broke. A recording captures the whole chain: the exact clicks, the order, the timing, and any error that flashes on screen. The developer can watch it once and reproduce the bug themselves, which is 90% of the battle.

The four things every bug report needs

1. The steps to reproduce — recorded from the start

Hit record before you trigger the bug, not after. The developer needs to see the path in, not just the crash. Start from a known place (a fresh page load, the home screen) so the steps are repeatable.

2. Expected vs. actual — out loud

This is the single highest-value habit. As you go, narrate: “I’m clicking Save, and I expect a confirmation… but instead the page reloads and my changes are gone.” That one sentence tells the developer what “broken” even means here. Turn your microphone on and just talk.

3. Your environment

Bugs often live in one browser or one OS. Say which browser or app version and which operating system you’re on. For a web bug, open the developer console (F12) so any red errors are captured on screen — that’s often the exact clue a developer needs.

4. Brevity

Keep it under two minutes. Record only the reproduction and trim the rest. A tight, specific clip gets triaged fast; a long one sits in the queue.

The right tool for it

You want a recorder that captures your screen, your narration (mic), and system sound together, shows the cursor clearly so the developer can follow your clicks, and lets you grab just a region when the bug is in one corner of the screen. Recording locally also matters here — bug reports often contain internal tools, staging data, or customer info you don’t want auto-uploaded to a cloud.

KeepCast does exactly this: screen + system audio + mic in one MP4, a clear synthetic cursor, region capture, and everything saved on your machine. (Local-first Windows app — join the waitlist.)

The 30-second version

Record from the start → say what you expected and what happened → show your browser/OS (and the console for web bugs) → keep it under two minutes → send. Do that, and “it’s broken” becomes “here’s exactly how to break it” — which is the difference between a bug that lingers and one that’s fixed today.
