Will Sizzledraft use my GitHub star count in the opening?

It can use the star count visible on the repository page as the first-three-seconds hook. That works well for mobile app repositories because stars give the opening a clear number, while README copy and code blocks are mostly static text. The count shown comes from the page captured during production.

Do I need a screen recording inside the README?

No, but an embedded recording or animated interface preview makes it easier to show the mobile app in use. Without one, the video relies on README screenshots, badges, the star count and code samples. Add a short demo near the README hero if the app's interaction is central to the pitch.

What video formats can I make from a mobile app repo?

Sizzledraft can render vertical video at 1080x1920 or horizontal video at 1920x1080. Both use 30fps H.264, and audio is normalised to -14 LUFS. Vertical fits mobile feeds, while horizontal gives wide README heroes, code blocks and multi-screen interface images more room.

Can I use a trending sound with the repository ad?

Sizzledraft hands over a link to the trending sound so you can attach it natively when posting. It does not bake that sound into the exported file because baked-in audio does not count as using the platform's sound. The rendered video's own audio is normalised to -14 LUFS.

Show your mobile app beyond the code

Sizzledraft turns a mobile app GitHub repository URL into a short video ad built from the repo's visible content and design cues. It captures the README hero, badges, star count and code blocks, then uses the star count as the opening hook while giving app footage and store ratings stronger visual emphasis when they appear on the page.

How do I turn my mobile app GitHub repo into a video ad?

Paste the public repository URL into Sizzledraft. The browser opens the GitHub page and captures real material from the README, including the hero image, platform badges, visible star count and selected code blocks. The first video is cut from the repository page alone, so a README with app screens or a short interface animation gives the video more product detail. Sizzledraft authors scenes using colours and visual cues available in the source, then renders every frame and adds synthesised audio. Later videos can accept a prompt, which lets you request a different angle, such as installation speed, an iOS feature or an Android workflow. The finished ad can be vertical at 1080x1920 or horizontal at 1920x1080, rendered at 30fps in H.264.

What should my README include before I make the ad?

Put the strongest proof near the top of the README. For a mobile app, that usually means a clear hero showing the interface, a short screen recording or several device screenshots, followed by platform badges and a concise description of the main task the app performs. Keep the GitHub star count visible because it can carry the opening three seconds. If store rating matters, add an accurate store badge or rating graphic to the README and keep it current. Include one short code block only when developer setup is part of the pitch, such as a compact installation command for an SDK-backed app. Long architecture notes, changelogs and dependency tables are useful documentation, but they give the video little movement and can bury the app itself.

Can a repo-based ad show my app in use and its store rating?

Yes, when the repository page already contains those assets. A README animation, embedded demo clip or sequence of mobile screenshots can show the app workflow, while an accurate App Store or Google Play badge can provide the store rating. Sizzledraft captures what the browser can see rather than inventing missing product footage or review data. If the repo contains only source code and installation text, the video can still lead with the star count, badges and code, but it will have less evidence of the user experience. Before generating the first cut, add a short visual path through the app's main job, such as creating a note, scanning a receipt or completing a workout. Pair it with the current rating graphic so viewers see both use and proof.

What the browser actually gets

The browser can capture the repository's README hero, badges, visible star count and code blocks exactly as they appear on GitHub. It can also use app screenshots or store-rating graphics embedded in the README, but it cannot infer an app walkthrough or current store rating when neither appears on the page. Because most remaining repo content is text, the star count usually provides the clearest opening hook.

The common mistake

A common mistake is opening with a dense README paragraph or code block before showing why the mobile app matters. Lead with the visible GitHub star count, then move immediately to the app in use and an accurate store-rating graphic embedded in the README.

A GitHub repository explains installation and architecture, but rarely shows the mobile app in use quickly enough for an ad.
The repository star count can establish interest in the first seconds, while README text and code blocks are harder to make visually engaging.
App store ratings and polished screen recordings often live outside the repository, so the GitHub page alone may not contain the strongest proof or product footage.
