The TS file format stores data in the TS format. Converting to OGG produces a audio file that encodes audio with the open-source Vorbis lossy codec in the Ogg container, achieving quality comparable to AAC at equivalent bitrates. This extracts the audio stream from the video container, discarding the video track. The audio track is decoded and re-encoded (or stream-copied if the codec matches) while the video frames are discarded. This makes OGG the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
