Two improvements:
1. DOWNLOAD FILENAME: instead of 'reel_<job-id>.mp4' (e.g. reel_25e076af7600.mp4),
downloads now have descriptive names like:
- 'Lady Gaga - Abracadabra - REEL.mp4'
- 'Modrijani - S teboj - REEL.mp4'
- 'Sarah Connor - FICKA - REEL.mp4'
2. PRE-UPLOAD VALIDATION: when filename doesn't follow 'Artist - Title' format,
browser prompts user for both fields. Without them, upload is blocked.
This prevents files with names like '12345.mp4' or 'video_final.mp4' from
being processed without identifying info.
Implementation:
- parse_artist_title() helper handles common formats:
- 'Artist - Title.mp4' / 'Artist – Title' (em-dash)
- 'Artist | Title' / 'Artist : Title'
- Strips noise: '(Official Music Video)', '(Audio)', '(HD)', '[Lyric Video]'
- Client-side parser mirrors backend (validation before upload)
- Backend accepts artist + title form fields (override parsed)
- Job stored with parsed_artist + parsed_title + has_clean_name fields
- YouTube jobs auto-fetch title via yt-dlp --info-only and parse it
- Filename hint to Scribe/Claude uses parsed values (cleaner than raw filename)
- Download endpoint uses build_download_filename() for content-disposition
- Jobs list shows 'Artist — Title' instead of raw filename
Result: downloaded reels are auto-named correctly for Facebook/Instagram
upload, no more renaming files manually.
Root cause: inline onclick with JSON.stringify(title) broke when title
contained quotes, special chars, or was empty. The HTML attribute parser
got confused by mismatched quotes, so click handler never fired.
Fix:
- Replaced inline onclick handlers with data-action attributes
- Added single delegated click listener at document level
- Title stored in element dataset (no HTML quoting issues)
- Added escapeHtml() helper for safe rendering of titles/errors
Now clicking Preview in the right sidebar opens the fullscreen modal
correctly, regardless of filename characters.
Previously: clicking Preview in jobs list showed a small inline video
within the job card row.
Now: clicking Preview opens a centered fullscreen modal with:
- Large video player (up to 95vw × 85vh) — same experience as bottom
live-preview but accessible from jobs list
- Auto-play, controls, native HTML5 video player
- Title shown below video for context
- Download button + Close button
- Click outside or ESC key to close
- Backdrop blur for focus
Removes the obsolete inline <video> element that was rendered hidden
in each job card. Body scroll locked while modal open.
1. Preview endpoint now supports HTTP Range requests (HTTP 206 Partial)
- HTML5 video player needs Range support to seek/buffer properly
- Without it, video would cut off after a few seconds
- Returns chunks of 64KB on demand
2. Left panel (upload form) is now sticky (position: sticky)
- Stays in view while right panel (jobs list) scrolls
- On mobile (<800px) reverts to normal flow
- Refactored analyze_with_claude into shared _build_analysis_prompt + _parse_llm_response helpers
- New analyze_with_gemini() using Gemini 3.1 Pro ($2/M in, MMMLU 92.6% — best multilingual)
- Unified analyze_with_llm(provider) dispatcher with auto-fallback (Claude → Gemini)
- API endpoint accepts llm_provider in StartJobIn (claude/gemini/auto)
- Frontend dropdown to pick LLM
- Default model is now Sonnet 4.6 (was Haiku 4.5) — 3x quality at 3x price (~3 cents/video)
- Gemini support is opt-in: needs GEMINI_API_KEY env var to activate
- 3-sample voting for auto-detect (start/middle/end of song) prevents lang switching mid-song
- Lock detected language for full transcription
- Anti-hallucination: condition_on_previous_text=False, temperature=0.0
- compression_ratio_threshold=2.4 (rejects repetitive hallucinations)
- log_prob_threshold=-1.0 (rejects low-confidence segments)
- no_speech_threshold=0.6 (more aggressive silence detection)
- Default Whisper model changed: small → medium (better for all langs incl. Slavic)
