How to Convert Files

Convert TS transport-stream video to and from common formats in your browser. All processing stays on your device.

What a TS file holds

TS stands for Transport Stream, the MPEG-2 transport stream format created to carry video and audio for broadcasting and streaming. It was designed to be robust over unreliable channels, so a receiver can start playing at any point and recover from errors, which is essential for live television.

A transport stream divides the media into small fixed-size packets, interleaving video, audio, and signalling data, with frequent timing and synchronisation information. This packet structure is what makes it resilient for over-the-air and network delivery, and it is why TS is used in digital TV and in streaming protocols that segment video into small chunks.

Strengths and limits

The transport stream's strength is robustness and streamability: its self-synchronising packets tolerate errors and allow playback to begin mid-stream, which is exactly what broadcast and live streaming require.

That packet overhead makes it slightly less efficient than file-oriented containers, and it is built for delivery rather than editing, so editing software often prefers a rewrapped file. The codecs inside vary, so a TS file's compatibility depends on its contents.

History of TS Format

The TS format was developed by the Moving Picture Experts Group (MPEG) in the early 1990s as part of the MPEG-2 standard. It was created to address the need for a reliable method of transmitting audio and video over broadcast and streaming channels, particularly in environments with potential data loss. This capability was crucial for live television, where interruptions could lead to viewer dissatisfaction.

Since its introduction, TS has been widely adopted in digital television broadcasting, satellite communications, and streaming services. Its standardization has led to the incorporation of various codecs within the TS container, enabling flexibility in media delivery. Tools for encoding and decoding TS files have also evolved, with software such as FFmpeg and VLC Media Player supporting TS natively, facilitating its integration into various workflows and applications.

Practical Use of TS

Choose TS when dealing with live broadcasts or streaming applications where error resilience is critical. It is particularly useful for scenarios requiring real-time playback, such as IPTV or over-the-air television. TS files are also suitable for archiving broadcast content, given their ability to encapsulate multiple streams. However, be mindful that some devices may have limited support for TS, so verifying compatibility is essential.

When converting to or from TS, consider the codecs used within the TS container. Ensure that the target format supports the audio and video codecs contained in the TS file. Use tools like FFmpeg for seamless conversion, but be prepared for potential quality loss if transcoding to a less efficient codec. Additionally, be aware of the file size implications, as TS files can be larger due to their error-correction features.

Working with TS files

You will encounter TS files from digital TV recordings, capture cards, and as the segments of adaptive streaming protocols.

To edit or share the video, convert or rewrap the TS into an MP4 container, which suits editing and plays reliably across devices while keeping the underlying video quality.
