Slower (est.) · seeders 10

Ranges below are seeders + size heuristics (probe_method=estimate_only)—not a peer speed probe, and not your ISP speed.

Use scenarios

Primary scenario

• Quality suspect (label vs size)

  Who it’s for Anyone before downloading

  Resolution label vs size looks inconsistent, or tier is suspect (heuristic score).

  Suggested action Recheck the list and source; prefer a more trusted release.

  Confidence：high · tier=suspect, score=20, has_video_asset

Other scenarios

Scenarios are filename/extension heuristics (file-type-scenario-engine). Streams and subtitle text are not read.

Audio languages

No audio language tokens in the name; may be a single default track or unlabeled embedded audio (streams not read).

Inferred from magnet name and video filenames only — not external subs; container audio tracks are not parsed.

External subtitle languages

No external subtitle files found; may be softsubs inside the container or none (tracks not inspected).

Guides

• How to read resolution & source

  1080p, WEB-DL, x265, etc. come from filenames—not measured quality. Check file size and the list before downloading.

• Play MKV and external subs

  Desktop: VLC / mpv / PotPlayer. Load sidecar subs from the same folder. We do not host players.

• How to read download ETA

  On-page ranges are seeder heuristics, not guaranteed speed tests. Never trust exact minutes without a real probe.

• Magnet check & safety habits

  Watch for exe/scripts in the list; select only the main video and subs. Use the check page for other magnets.
