ffprobe -i hsoda030_conv021021_minbest.mp4 Look for Stream #0:2(eng): Subtitle . If file size is critical (e.g., exact target of 500 MB), use two-pass encoding: hsoda030engsub convert021021 min best
This yields but takes 2× time. 6. Common Pitfalls (and How to Avoid Them) | Problem | Solution | |---------|----------| | Subtitles disappear after conversion | Use -c:s copy with MKV output, or in HandBrake add subtitle track manually. | | File not smaller (or larger!) | You used CRF too low (e.g., 18). Increase CRF to 24. Or your source is already HEVC. | | “Convert021021” fluke – date mismatch | Ignore date. Use modern codecs. | | Audio sounds tinny | Increase audio bitrate to 160kbps or use -c:a libopus -b:a 96k for Opus (smaller/better). | 7. Legal & Ethical Note If hsoda030engsub is copyrighted material you do not own, converting it for personal archival may be permissible under fair use in some jurisdictions, but distributing the converted file is not. Always respect intellectual property laws. | Codec | Compression | Quality | Encoding
