Creative video editing with Jetpack Media3 and Gemini
summary
Shows a working Android pipeline that turns uploaded phone clips into trimmed, concatenated highlights: videos upload to Cloud Storage, a Gemini API via Firebase call (Vertex AI Pro model 2.5, temperature 0) returns a strict JSON of start/end timestamps, and Jetpack Media3 builds a composition object for preview and Transformer export. Live demo proves it produces one‑minute vlogs from many clips, with upload/analysis latency as the main bottleneck.
