Get your computer equipped with the video joiner. From its main screen, find "Open File" to import TS files from local folder. Simply, drag and drop your TS videos to the specified area.
Next, head to "Format" to set up merging mode and output format. To join TS files without re-encoding, you have to work with the high-speed mode, which is at the focus of merging identical media files with remaining the original quality. Afterward, select "Original" as the output format from "General Video".
Afterwards, click on "OK" to return to the beginning interface. You can start previewing your TS videos. As for unnecessary content, easily slide the yellow timeline to clear it. Also, the program provides options to rename and rearrange media files. Do it as you wish if need be.
Eventually, find and tap on "Convert" at the bottom right corner. This action will activate the merging process. Shortly after, your TS files would be merged together at 60X high speed with zero quality loss.
