# aidemo blog > Practical, evidence-backed articles on product demo videos — scripting, recording, automation, AI tooling, and demos-as-code — from the team behind aidemo, the open-source engine that turns an agent-authored storyboard into a narrated, captioned demo video. Every article is available as raw markdown at the .md URLs below (the .md suffix on any article URL). ## Demo Tools & Alternatives - [AI demo video generators: what the label actually covers](https://aidemo.top/blog/ai-demo-video-generators/index.md): Four unrelated tools rank for 'AI demo video generator,' and two never output a video of your product. A mechanism map so you buy the right object. - [Arcade vs Navattic vs Storylane: picking an interactive demo platform](https://aidemo.top/blog/arcade-vs-navattic-vs-storylane/index.md): They rank on the same grids, but Navattic clones your DOM, Arcade stitches screenshots, and Storylane does both. Pick by capture engine, not feature count. - [Camtasia alternatives for software demos and tutorials](https://aidemo.top/blog/camtasia-alternatives/index.md): TechSmith retired Camtasia's perpetual license, and the timeline was always the real bill. The alternatives, sorted by who does the editing. - [Interactive product demos vs video demos: when each wins](https://aidemo.top/blog/interactive-demo-vs-video-demo/index.md): One is a program you drive, the other a file that plays anywhere. Where clickable tours beat video, where video wins, and the two costs listicles skip. - [Loom alternatives for product demos after the Atlassian era](https://aidemo.top/blog/loom-alternatives-for-product-demos/index.md): Loom is async video messaging that Atlassian now owns, not a product-demo tool. Sort the alternatives by which of Loom's jobs you are actually replacing. - [Open-source demo video tools, scored by license and install reality](https://aidemo.top/blog/open-source-demo-video-tools/index.md): Not everything on GitHub is open source. Cap, vhs, Remotion, Revideo, editly, and aidemo, scored on OSI compliance, install friction, and what the pixels are. - [Screen Studio alternatives for Windows, Linux, and CI](https://aidemo.top/blog/screen-studio-alternatives/index.md): Screen Studio is macOS-only and subscription-only now. Here is the honest, per-platform map of what replaces it on Windows, Linux, and in CI. ## Demo Automation - [Automated product demo videos: regenerate, don't re-record](https://aidemo.top/blog/automated-product-demo-videos/index.md): Four unrelated machines ship under one label. Only one makes 'the product changed' and 'the demo is current' the same event. - [Automating product screenshots for docs and marketing](https://aidemo.top/blog/automating-product-screenshots/index.md): The complete stills playbook: one YAML for every screenshot, a pull request that recaptures them on a schedule, and a visual regression test you get for free. - [Rendering demo videos in CI: a GitHub Actions walkthrough](https://aidemo.top/blog/demo-videos-in-ci/index.md): GitHub's runner ships Chrome but not ffmpeg. Here is what a video-rendering job actually needs, how to trigger it, and where the file should land. - [README GIFs that update themselves](https://aidemo.top/blog/readme-gifs-that-update-themselves/index.md): A 20-second demo GIF can weigh 18 MB, past GitHub's 10 MB ceiling. The format rules, the real size math, and a recapture loop that keeps it honest. - [Why every product demo is out of date (and what rot costs)](https://aidemo.top/blog/why-product-demos-go-stale/index.md): Linear redrew every header, icon, and nav in one release, and every demo filmed before that day went wrong in every frame. This is how fast demos rot. ## Product Demo Videos - [AI voiceover for demo videos: quality, cost, and workflow](https://aidemo.top/blog/ai-voiceover-for-demo-videos/index.md): AI voiceover per minute is settled and cheap. The real questions: which TTS gives you consistency and one-line re-renders, and where a human voice still wins. - [App preview videos: hitting App Store and Play specs without a reshoot](https://aidemo.top/blog/app-preview-video/index.md): Apple wants an uploaded H.264 file at 886 x 1920; Google Play wants a YouTube link. The exact cross-store specs, and how to hit them without a reshoot. - [Captions on demo videos: the accessibility case and the numbers](https://aidemo.top/blog/demo-video-captions/index.md): Most demo views start muted, so the caption is the demo, not the soundtrack: the timing, the formats, and the WCAG rule that decide whether the words land. - [Demo video script template: problem, walkthrough, proof](https://aidemo.top/blog/demo-video-script-template/index.md): Narration runs about 2.5 words a second, so a demo's runtime is a word budget. Grab a copy-paste script skeleton and two worked scripts, counted line by line. - [How long should a demo video be? The retention math](https://aidemo.top/blog/how-long-should-a-demo-video-be/index.md): Most demos run longer than they should, and that is an editing problem. Here is the target length for every placement, plus what to cut first. - [How to make a product demo video (that people finish)](https://aidemo.top/blog/how-to-make-a-product-demo-video/index.md): The playbook for a demo people actually finish: script first, record second, with the word, scene, and length budgets that decide every second. - [What makes a screen recording look professional](https://aidemo.top/blog/professional-screen-recordings/index.md): The polish people call professional is five named transforms with parameters, not a knack. Here is what each one does and why a bad zoom is a recompose. - [SaaS demo video examples: what the best ones do differently](https://aidemo.top/blog/saas-demo-video-examples/index.md): Six real SaaS demo videos from Vercel, Notion, Loom, Linear, Warp, and Retool, read with a stopwatch and a transcript instead of a mood board. ## Demos as Code - [Letting a coding agent make your demo video](https://aidemo.top/blog/coding-agents-that-make-demo-videos/index.md): A coding agent can explore your app and write the demo storyboard. Driving the browser live is the one thing it must not do, and here is exactly why. - [Demos as code: commit the storyboard, render the video](https://aidemo.top/blog/demos-as-code/index.md): A recording is a performance you own and maintain. A spec is text you can diff, review, regenerate, and hand to an agent. That decides everything downstream. - [Deterministic browser automation for video capture](https://aidemo.top/blog/deterministic-browser-automation-for-video/index.md): A test that flakes just reruns. A demo that flakes ships the stutter. The eight-variable checklist for making one browser flow render the same pixels twice. - [Multi-language product demo videos from one recording](https://aidemo.top/blog/multi-language-product-demo-videos/index.md): Localizing a demo doesn't mean re-shooting it five times. Keep one recorded take, swap the words, and do the honest math on where each locale really costs you. - [Personalized demo videos at scale: the template-render pattern](https://aidemo.top/blog/personalized-demo-videos-at-scale/index.md): A merge field with the prospect's name is not a demo that shows their data. Three depths of personalization, priced honestly for a fifty-prospect batch. - [Video-as-code tools: Remotion, Revideo, editly, vhs — and real-UI capture](https://aidemo.top/blog/video-as-code-tools/index.md): Remotion and Revideo draw every frame, editly stitches clips, vhs replays a terminal, real-UI capture films your product. Five models, one map. ## Screen Recording - [How to record your screen in high quality: the settings that matter](https://aidemo.top/blog/how-to-record-your-screen-in-high-quality/index.md): Blurry text, a laggy cursor, the wrong frame rate: high quality is a handful of capture settings, each with one number and a one-line fix. - [How to record just one browser tab (three ways, one clean result)](https://aidemo.top/blog/record-a-browser-tab/index.md): Recording one browser tab is picking a capture surface, not cropping your desktop. Three ways to do it, scored on fidelity, what leaks, and repeatability. ## Video Documentation & Tutorials - [Video documentation for software: when the medium earns its keep](https://aidemo.top/blog/video-documentation/index.md): The evidence-based case for video as a documentation medium: where a clip beats a paragraph, where it quietly loses, and how to route each doc job. - [Video vs written documentation: the decision, with evidence](https://aidemo.top/blog/video-vs-written-documentation/index.md): Stop asking whether your docs should be video or text. Score each doc job on four axes and read the right format off the total, evidence not vibes. ## Video Marketing for Software - [Does video actually increase conversion? Tracing the 80% claim](https://aidemo.top/blog/does-video-increase-conversion/index.md): The famous 80% conversion lift traces to one 2011 A/B test. Here is what a 35,000-page analysis and your LCP budget actually say about video. - [Video marketing for software: one recording, every channel](https://aidemo.top/blog/video-marketing-for-software/index.md): Your buyers sit on nine surfaces; your budget is for one recording. The channel-by-channel spec that turns a single demo into every placement it needs. ## Optional - [Full corpus, one file](https://aidemo.top/blog/llms-full.txt): every article concatenated as markdown - [Editorial policy](https://aidemo.top/blog/editorial-policy/): how articles are researched, cited, and corrected - [Blog home (HTML)](https://aidemo.top/blog/) - [Sitemap](https://aidemo.top/blog/sitemap.xml)
