TSConverter Tips: Best Settings for Streaming and Playback

Streaming and smooth playback from TS files requires the right balance of encoding settings, container choice, and bitrate. Use the following practical tips and recommended presets to get the best results with TSConverter.

1. Choose the right output container

• MP4 (H.264/AAC): Best for compatibility across devices and streaming platforms.
• MKV: Use when you need multiple audio/subtitle tracks or lossless streams.
• TS: Keep only if downstream systems require MPEG-TS (broadcast workflows).

2. Video codec and profile

• Codec: Use H.264 (libx264) for general streaming; choose H.265 (HEVC) only if target devices support it and you need ~30–50% smaller files.
• Profile: Set to Main for broad compatibility; use High for higher-quality playback on modern devices.
• Level: Use 4.0–4.2 for 1080p, 5.0 for 4K.

3. Bitrate vs. CRF (quality)

• Streaming (adaptive/online): Use ABR (average bitrate) or VBR with explicit bitrate targets. Recommended ranges:
  • 480p: 800–1,200 kbps
  • 720p: 1,500–3,000 kbps
  • 1080p: 3,500–6,000 kbps
  • 4K: 15,000–25,000 kbps
• Local playback / storage: Prefer CRF (constant quality). Recommended CRF values for x264:
  • Good: CRF 20
  • High quality: CRF 18
  • Near-lossless: CRF 16 or lower
    Use slower presets (e.g., medium or slow) for better compression efficiency.

4. Keyframe / GOP settings

• For streaming, set keyframe interval (GOP) to match segment duration:
  • HLS/DASH segments: use 2–4 seconds (e.g., GOP size = fps × 2 or ×4).
• Force keyframes on segment boundaries to avoid playback stutter when switching streams.

5. Audio settings

• Codec: AAC (LC) for widest compatibility.
• Channels: Stereo is standard; use 5.1 only if source and playback support it.
• Bitrate: 96–128 kbps for stereo; 192–384 kbps for 5.1.

6. Subtitle and metadata handling

• Embed subtitles in MKV or sidecar files (WebVTT for web streaming).
• Preserve language and timing metadata when remuxing to avoid sync issues.

7. Remux vs. Re-encode

• Remux (container change only) whenever codecs are already compatible—this is fast and lossless.
• Re-encode only when you need codec change, bitrate reduction, or quality improvements.

8. Batch processing tips

• Use consistent naming and output folders.
• Test presets on a short clip before applying to a full batch.
• Enable multi-threading/CPU affinity if TSConverter exposes those options.

9. Network and streaming protocol considerations

• For HLS: produce multiple bitrate renditions (480p/720p/1080p) and a master playlist.
• For low-latency streaming, keep segment durations short (1–2s) and tune GOP/keyframe intervals accordingly.

10. Quick recommended presets

• Web streaming (1080p): H.264, High profile, Level 4.2, CRF 20 or VBR 5,000 kbps, AAC 128 kbps, GOP 2s.
• Mobile (720p): H.264, Main, CRF 20 or VBR 2,500 kbps, AAC 96 kbps, GOP 2s.
• Archival/local (1080p): H.264, High, CRF 18, AAC 192 kbps, slow preset.
