How to convert TS to MP4

  1. Add your .TS file - drop it in the box above or click to browse.
  2. Convert it to .MP4 in a few seconds.
  3. Download your new .MP4 file.

What to expect

  • A remux (ffmpeg -c copy) copies the video and audio streams unchanged - no quality loss and near-instant completion regardless of file size.
  • TV recordings often carry AC-3 (Dolby) audio, which many phones and smart TVs will not play inside an MP4; convert audio to AAC with ffmpeg -i input.ts -c:v copy -c:a aac output.mp4.
  • If a .ts file opens as code in a text editor, it is a TypeScript source file, not a video - video TS files are binary and cannot be converted to MP4.

Frequently asked questions

Does converting TS to MP4 reduce quality?
Only if you re-encode. FFmpeg with -c copy remuxes the streams without touching them, so quality is identical to the source. HandBrake and VLC always re-encode and will reduce quality depending on the bitrate settings.
Why does FFmpeg finish so quickly?
Because no decoding or encoding takes place - FFmpeg just moves the existing H.264/AAC streams from the TS container into an MP4 container, so even a 20 GB file finishes in seconds.
My converted MP4 has no audio - what do I do?
The audio is most likely AC-3 (Dolby), which many devices do not support inside MP4. Re-encode only the audio with ffmpeg -i input.ts -c:v copy -c:a aac output.mp4.
Can I join multiple .ts segments into one MP4?
Yes - list the files in a text file and run ffmpeg -f concat -safe 0 -i list.txt -c copy output.mp4 to combine them without any quality loss.
