Can Quicktime convert Video_TS content?

Just wondering if Quicktime can convert the contents of a Video_TS folder into a single-file video format, such as .mp4 or .mkv.

QT 7 can convert VOB files to any video compression format supported by your QT codec configuration if, and only if, your QT codec configuration includes the MPEG-2 Playback codec. Unfortunately, this codec does not support audio conversion of AC3. To convert VIDEO_TS folder content to MP4 or MKV files and preserve audio, video, multichannel, alternative audio, chapter, and/or subtitle content, most users would the free HandBrake app. I use it to create M4V files with H.264/AAC/AC3/Chapter tracks with burned-in "forced" subtitles as appropriate for iTunes management and playback on multiple Apple devices.
