Demo video guide

Recording a product demo, screen capture settings, automatic zoom moves, aspect ratios, export settings, length, backgrounds and frames, and the mistakes that lose viewers.

• How to record a product demoPlanning, recording and polishing a short product demo — what to show, what to leave out, and how to avoid re-recording six times.
• Screen recording settings that matterWindow size, resolution, frame rate, cursor and audio — the capture choices that decide how the final video looks.
• Zoom moves that help rather than distractHow the app decides where to zoom, why it does not track your cursor, and how to make moves that do not make people seasick.
• Choosing an aspect ratio16:9, 1:1, 4:5 and 9:16 — where each one belongs, and why a widescreen screen recording does not become a vertical video for free.
• Export settingsWhat resolution and frame rate to export, how the bitrate is chosen, why the file is MP4/H.264, and what to do when export is unavailable.
• How long should a demo be?Why thirty to sixty seconds is the working range, how to structure it, and what to cut when it runs long.
• Backgrounds, frames and paddingPadding, rounded corners, shadow and the window frame — the composition choices that make a screen recording look designed.
• Mistakes that lose viewersThe recurring problems in product demos — the long runway, the tour, unreadable text, motion sickness, fake cursors — and what to do instead.

Export uses WebCodecs, which today means Chrome or Edge on a desktop — recording and editing work more widely, but encoding does not, and the app says so before you start rather than after. Nothing here is a claim about what a demo video will do for your conversion rate; it is a description of how the tool works and what generally reads well.
