About MPEG Transport Stream (TS)
An MPEG transport stream (TS, MTS, M2TS) is the container used for digital TV broadcasting and Blu-ray. It is built from small fixed-size packets that tolerate transmission errors.
TV recordings, AVCHD camcorder files (.mts), Blu-ray discs (.m2ts) and HLS streaming segments.
The packet structure adds overhead, and many editors and phones do not open TS files directly.

Why won't my media player open the .ts file I recorded? A transport stream is written for broadcast, so many players expect a renamed or converted container before they accept it.
About MP4
MP4 (MPEG-4 Part 14) is a container format standardised by ISO. It usually holds H.264 or H.265 video with AAC audio, and it can also carry subtitles and chapter markers.
It is the most widely supported video format: phones, browsers, smart TVs and video sites all play it.
The video inside an MP4 is almost always compressed with a lossy codec, so every re-encode loses a little quality.
Why convert video to MP4? Almost every device, browser and platform plays it, so an MP4 almost never needs a second conversion.
What changes when you convert TS to MP4
- The TS is re-encoded into MP4 at the default quality settings, so the result looks close to the original but is not bit-identical.

Before you convert TS to MP4, you can adjust: Video codec, Rate control, Quality (CRF), Video bitrate, Resolution, Width, Height, Scale fit, Frame rate, Encoder preset, Audio codec, Audio bitrate, Trim start, Trim duration, and Remove metadata.
