How Shorts Maker helps creators publish faster
Many creators need a simple way to finish tasks without losing momentum. Shorts Maker removes complexity by combining the most common editing, exporting, and optimization steps into one interface. This means less switching between apps and more time spent publishing.
The tool is built with fast load times in mind. It keeps assets on your device when possible, so you can work privately and avoid unnecessary uploads. That helps creators stay productive on mobile, desktop, and low-bandwidth connections.
Whether you are a beginner or a professional, this tool gives you actionable controls with simple defaults. Use the included presets for the fastest result, then fine tune the output as needed for brand-safe, platform-ready content.
How to use Shorts Maker
Upload video or link
Drag and drop your MP4/WebM video or paste a public video URL.
Analyze viral moments
Let our on-device AI analyze speech energy, pacing, and hooks to clip top highlights.
Customize style & download
Choose a kinetic caption theme, verify the 9:16 speaker crop, and export in HD without watermarks.
Creator tips
- Verify that the first 3 seconds contain a strong visual pattern interrupt and caption hook.
- Use the video compressor tool to shrink files before upload if you are on a restricted mobile network.
- A/B test three different dynamic hook variants to see which segment captures the platform algorithm fastest.
While other tools charge $20+/mo and require slow cloud uploads, Seloice is free, secure, and processes everything on-device.
Troubleshooting
AI analysis fails to start
Ensure you have a stable network to fetch initial WASM modules and that your browser supports WebAssembly.
Crop frame cuts off speaker
Use the manual slider in the preview workspace to adjust and lock the 9:16 bounding box on active participants.
Export times are slow
Close other browser tabs to free up system memory (RAM). Browser-based editing is CPU-heavy.
Frequently asked questions
How does the AI determine viral potential?
Our localized AI processes the video audio stream to index speech pacing, structural audience triggers, volume shifts, and keyword clusters, calculating a real-time virality probability score.
Is my media uploaded to a server?
No. Unlike other video SaaS tools, Seloice processes and renders your video entirely in your browser using high-performance WebAssembly (WASM) and client-side FFmpeg. Your data never leaves your device.
Can I choose standard caption styles?
Yes. You can style subtitles with custom animated fonts, highlighted words (Hormozi style), and placement presets.
Is there a video file size limit?
The browser processing supports video files up to 200MB or up to 20 minutes of footage depending on your device RAM.
