What is a TS file?
The broadcast and streaming container used by TV tuners, IPTV and HLS. Recordings from TV cards are often .ts files.
Pros
- Robust against transmission errors
- Used by HLS streaming
Cons
- Slightly larger than MP4
- Many editors and phones do not open it
How to open TS files
VLC Media Player (free, Windows/macOS/Linux/Android/iOS) opens TS files with almost any codec. If a specific app won't open it, convert it to MP4.
Is TS lossy or lossless?
TS is a container, not a codec — whether it is lossy depends on the streams inside (H.264 or MPEG-2 video with AAC or AC-3 audio). In practice almost all TS files use lossy compression.
When should you convert TS?
Recordings from TV cards are often .ts files. If the app or device you need doesn't accept TS, convert it to MP4 — the most widely supported alternative.
