A MP4 video file follows the JPEG image file in a Android Phone ‘Motion photo’ with a filename starting MVIMG<\/p>\n
EXIFTool can extract the video files with a single command, from Phil Harvey EXIFTool Developer:<\/p>\n
\nHere is a command that will extract the video from all jpg images in a directory and store the videos with the same file name as the jpg but with extension .mp4:<\/p>\nexiftool -b -p “${trailer;s\/.*(\\0\\0\\0\\x1cftypisom)\/$1\/s}” -ext jpg -w mp4 DIR<\/strong><\/p>\n

\n\u00a0…where\u00a0DIR\u00a0is the name of a directory\/folder containing the images.\u00a0 On Mac\/Linux\/PowerShell, use single quotes (‘) instead of double quotes (“) around arguments containing a dollar sign ($).<\/div>\n<\/div>\nWow, thanks, that works. I would never have been able to figure that out myself. Would you be so kind as to explain the “-p” parameter to me, please?<\/p>\n-b
\nOutput metadata in binary format. That’s what I’ve tried.<\/p>\n-p “${trailer;s\/.*(\\0\\0\\0\\x1cftypisom)\/$1\/s}”
\nWhat the hell are you doing here? I found this link but it doesn’t help me:
\nhttps:\/\/exiftool.org\/exiftool_pod.html#Advanced-formatting-feature<\/p>\n-ext jpg
\nProcess files with the specified extension<\/p>\n-w mp4
\nNew filename extension<\/p>\nDIR
\nDirectory or filename<\/p><\/div>\n<\/div>\nThis uses the advanced formatting feature as you surmised to remove everything before the MP4 header.\u00a0 The “\\0\\0\\0\\x1cftypisom” string is the binary MP4 header.\u00a0 “.*” is everything before that.\u00a0 The s\/\/\/ is the Perl substitution operator (ie. search and replace), and it replaces everything up to and including the header with just the header (“$1” is everything inside the brackets in the search pattern of the substitution operator).\u00a0 Read about “regular expressions” if you want to know more about the syntax.<\/p>\n– Phil<\/p><\/div>\n<\/blockquote>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
