threads=auto spawns one decode thread per logical core per decoder (16 observed on a 24-core box); with cores-2 render workers decoding concurrently the machine is oversubscribed several times over and the playback-audio render thread gets starved (late chunks are dropped). 4 threads decode 1080p h264 far past real-time; preview throughput comes from the worker pool, not per-decoder threading. Applies to both the software open path and the hwaccel open path.

Roadmap
| Version | Theme | Core Deliverables | Boundary Notes |
|---|---|---|---|
| 0.3 | Plugin Architecture Milestone | Production-ready OpenFX host support | Not about quantity of plugins, but "any OFX plugin loads without crashing" |
| 0.4 | Color, Audio & Performance | .cube/.3dl support, scopes (waveform/vectorscope/histogram), three-way color wheels, waveform auto-sync, BWF timecode sync, audio meters (LUFS/VU), proxy media workflow, hardware-accelerated export (NVENC/VideoToolbox), batch render queue |
Combines the previous 0.4-0.6 scope into one usability milestone: color workflow, audio sync, and 4K/8K performance |
| 0.5 | Animation, Tracking & Collaboration | Bézier keyframe curve editor, basic point tracking, image stabilizer, full multicam angle switching, OpenTimelineIO, EDL/XML import/export | Combines the previous 0.7-0.8 scope into one timeline/interchange milestone |
| 0.6 | Stability Milestone | Project file format freeze (backward compatibility promise), crash recovery, autosave, memory optimization | "Feature freeze" testing period before 1.0 |
| 1.0 | Production Ready | Complete documentation, installers, known issues list, community support channels | Declared "ready for serious projects" |
