Orev MP4 Compilation Studio - UI Phase 10.2 Fast Export Toast and Long Splice Hotfix

MP4 Clip Vault

Drop MP4 compilation source clips here. Add or relink media without sending files anywhere.

Compact intake railClip loading stays compact; header commands use controlled dropdown menus with only one menu open at a time.

Add or relink MP4 outputs Multiple files supported. Phase 10.2 keeps Fast 5.1 MP4 available from the Export dropdown and export panel, now with toast feedback and long-splice guards.

The master bus is browser-native. Fades and envelopes are applied during preview and stitched recording. The limiter uses Web Audio when the browser allows it.

Phase 8.4 Fast Assembly and Source-Preserve Export

Strict match: resolution, dimensions, and container

Fast path waiting for timeline data.

Phase 8.4 keeps the uploaded split FFmpeg WASM batch, makes Fast 5.1 MP4 visible as its own export action, and refuses zero-byte browser recorder downloads.

For maximum speed and original audio preservation, use source-preserve MP4 when you can accept hard cuts and no burned-in overlays. Use Record Stitch when the final video must include transitions, gaps, overlays, lower thirds, watermarks, fades, or gain processing.

Projects still save references, not embedded video. Phase 6 stores fingerprints for reliable matching. Optional cache uses this browser's IndexedDB storage and can be cleared anytime.

Export

01 Run Gate Start with Preflight to check duration, missing media, warnings, and browser capability. Uses: Run Preflight

02 Auto Route Let the app pick strict split FFmpeg where possible, then fall back to Record Stitch. Uses: Auto Export

03 Fast 5.1 Use source-preserve MP4 when speed and original audio matter more than burned-in effects. Uses: Fast 5.1 MP4

04 Record / Package Use Record Stitch for overlays and transitions, then ship EDL, reports, playlists, and QA. Uses: Record Stitch + package tools

Preferred recording type Monitor audio during export

Fast 5.1 MP4Fast source-preserve MP4 stitch for compatible full MP4 clips. Skips rendered effects by design.

Split FFmpeg idle. Strict stitch keeps the exact timeline rules; Fast 5.1 MP4 preserves source streams and flattens render-only effects to hard cuts.

Idle.

Auto Export keeps the safe behavior: strict split FFmpeg when possible, otherwise Record Stitch. Use Fast 5.1 MP4 when speed and original source audio preservation matter more than rendered effects.
