How to convert MKV to MP4 on Mac?
"I was wondering if there was any way to convert an h.264 mkv file (with subtitles) into a mp4 file on Mac, for watching MKV on new iPhone 3GS without losing the quality. Any freeware or shareware suggestion would be greatly appreciated."
MKV (Matroska Video) is a popular format for online video distribution (particularly through BitTorrent networks and all). It is an open and free container format. One of its advantages is that it can keep a number of video, audio, picture subtitle components in just one file. One popular use of .mkv files is to store high-definition (HD) videos, in formats like H.264. Matroska video files end with the extension .mkv (may also contain audio and subtitle), while audio only files are .mka and subtitle files are .mks Typically, you would find a .mkv file – that is also what I have come across.
You can play .mkv files in Mac OS X using VLC player without downloading any additional codecs, but what if you need to convert MKV movies to MP4 video, for example, to play on other devices (like iPod, Apple TV, iPhone etc.)? Most solutions online require Quicktime Pro or Perian, or has severe restrictions regarding the encoding types allowed within the .mkv container format .
