Sebastjan Artič c94e6214ca Edit: instant client-side preview with low-q source ... User feedback: 'predvaja odsek in začne iz nule kar ni ok, ne moremo premikati levo dolj levo... za to bi rabili low-q?' REPLACED render-on-demand approach with low-q source download: 1. Backend: GET /api/source-video/{id}?quality=low - 480p re-encode of full source (cached after first request) - veryfast preset, CRF 28 - First request: ~5-10s (depends on song length) - Subsequent: instant (cached) 2. Frontend: Edit modal loads ?quality=low - 'Pripravljam predogled (~5s prvič, potem instant)' status - Once loaded: ALL preview is client-side instant - 'Predvajaj odsek' jumps to trimStart and plays - Auto-stop at trimEnd (loops back) - Drag handles DURING playback = instant seek (browser scrubs in 5MB) - Drag NOT blocked during play (you can fine-tune in/out live) 3. Removed old /api/preview-clip endpoint logic (no longer needed) Note: kept the route as cache cleanup for old jobs Workflow now: - Open Edit → 5s wait first time - Drag handles freely (instant scrubbing) - Click Predvajaj → starts at trimStart immediately - Drag handles WHILE playing → live preview - Save when satisfied → 70s full render		2026-04-30 12:14:37 +00:00
