VidWeave: On-Device Video Export That Keeps Edits Accurate

VidWeave is a mobile video studio for stitching clips, photos, and sound into shareable stories. The editor itself was not the hard sell. Trust was. Users trim, crop, slow clips, and tweak colour, then expect the export to match what they saw on the timeline, whether they pick 720p, 1080p, or 4K for Instagram, YouTube, or something else. On a phone that means local rendering. If crop math, letterboxing, or tone shifts when the output size changes, the product feels broken even when the preview looked fine.

Building Cadora: On-Device 3D CAD Where Face IDs Matter More Than Triangles

I shipped Cadora — solid modelling on a phone. The hard part wasn’t drawing triangles. It was keeping logical faces alive so Push/Pull still makes sense after a boolean.

Building Songora: Rendering a Full Song on a Phone Without Sending Audio to the Cloud

I shipped Songora — describe an idea, get a song. The interesting part wasn’t the prompt. It was rendering melody, vocals, and a wavetable mix on-device, and refusing to fake a vocal track when the phone couldn’t sing.

Building VidWeave: On-Device Video Rendering That Keeps Edits Accurate

Last week I shipped VidWeave - a mobile video studio. The hardest (and most interesting) part wasn’t the editor UI. It was rendering on-device at multiple resolutions without breaking the user’s edits.
