Preview and browser export

Deterministic local export, formats, audio, captions, alpha, and device capability limits.

Parity

Live preview, still capture, and video export use the same composition graph, fixed-step clock, and audio-frame contract. Identical timestamps and seeds produce equivalent frames within the renderer tolerance.

Capability limits

Novus prefers native browser encoders and retains a tested FFmpeg/WASM fallback. Supported desktop hardware may export up to 4K. Constrained phones are limited to 1080p to avoid failed or corrupted exports.

Local rendering

Rendering remains on your device; there is no cloud-render queue. Audio inclusion, trims, captions, platform dimensions, frame rate, and alpha support depend on the selected format.
