(To get rid of display artifacts, Get Info and set 'Open in Low Resolution.' ) In the past I used those apps to wrangle iMovie 1-6's DV clips. MPEG Streamclip has not been updated since 2012 but it still works OK in Mojave. I am also evaluating how to replace 32-bit QuickTime Player 7 Pro and MPEG Streamclip when Catalina finally breaks them. 2) If the MOV file contains MPEG-4/AAC or H.264/AAC plus other content (e.g., an AC3 audio stream or an TEXT chapter track), then you can use the free MPEG Streamclip app to copy the MPEG-4 video and audio data to a real MP4 file container and simultaneously filter out non-MP4 file data tracks. It can play many movie files, not only MPEGs it can convert MPEG files between muxed/demuxed formats for authoring it can encode movies to many formats, including iPod it can cut, trim and join movies. MPEG Streamclip is a powerful free video converter, player, editor for Mac and Windows.
