What is a TS file?
TS — MPEG transport stream
Use the format TS
A concrete example
Prepare an MP4 copy of a transport stream recording.
Useful checks
Check the cuts and the selected audio track. An interrupted stream may have synchronization errors.
Choose a conversion
Keep the original and open the result in the software or on the device that will need to use it.
Your questions about this format
How to choose between MP4, WEBM, and MKV?
MP4 is suitable for many sharing purposes; WEBM is particularly intended for web playback. MKV may be better suited for content with multiple tracks. Look at the outputs offered for your file and test the result on the player you will actually use.
Can I extract only the audio from my video?
Yes, if MP3 is listed among the outputs of your source. Add the video, choose MP3, and start the conversion. The file must contain an audio track: a silent video cannot produce a sound recording.
Why am I being offered MKV for tracks and subtitles?
Not all outputs retain the same tracks. If the engine indicates that a MKV container is required, go back to the output selection and choose MKV instead of forcing a conversion that would remove elements. This output may fall under NoLimit.
How many videos can I convert for free?
The free offer allows one video per day, within the total quota of ten files and the limit of 100 MB per file. A batch of three files does not add three video rights: the video quota remains shared. A valid NoLimit access adjusts the limits according to the displayed offer.
What is it?
TS is the format of digital television: it's what your set-top box receives over the antenna, cable or satellite, and what your digital recorder saves to disk.
Its distinctive feature is that it was designed for a stream, not a file: the data is split into small, fixed-size packets, each of which can be decoded independently. Interference damages a few packets, not the entire broadcast.
History & origin
The transport stream was defined in the MPEG-2 standard in the mid-1990s for television broadcasting.
It found an unexpected second life with internet streaming: HLS, used by most video platforms, breaks videos down into a multitude of small TS segments.
Why it is useful
Remarkable resilience to transmission errors, and the ability to play a file even when it's incomplete.
It handles multiple programs, multiple audio tracks and teletext within a single stream.
Limits & drawbacks
The packet-based structure needlessly bloats a file meant for storage rather than broadcast.
It's poorly supported by editing software and consumer media players.
Practical tips
To keep a TV recording, convert it to MP4: you'll gain in both file size and compatibility.
Converting also lets you trim out the commercials and keep just the program.
