Lazarus S01e04 Hevc (2026)

If you plan to encode all episodes of season 1, create a simple (Windows) or shell script (macOS/Linux).

| Symptom | Likely Cause | Fix | |---------|--------------|-----| | | RF too low (over‑compression) or hardware cannot decode HEVC at 4K. | Raise -crf to 22‑24, or use a lower resolution (1080p). | | No sound | Audio not copied ( -c:a copy ) but source uses a codec unsupported by your player. | Convert audio to AAC ( -c:a aac -b:a 384k ). | | Subtitle missing | Subtitles were PGS (image) and you tried to “copy” into MP4 (which doesn’t support them). | Keep the container as MKV, or burn them in with -vf subtitles . | | File size huge (≥ source) | You used -preset veryslow with an extremely low crf (e.g., 15). | Increase crf to 20‑22 for comparable quality with smaller size. | | Player says “Unsupported codec” | Using an older player without HEVC support. | Update VLC or use a player that supports hardware‑accelerated HEVC (MPC‑Hc, PotPlayer). | | Sync drift (audio ahead/behind) | Variable framerate source + naive copy. | Add -vsync 2 in FFmpeg or enable “Constant Framerate” in HandBrake (under Filters → Framerate ). | lazarus s01e04 hevc
