I would like to know if the following is possible.
Is there a way in AppleScript to get file metadata information.
I am going to merge many video (i.e MP4, m44…) files together. Each of the files are located under a specific folder and were recorded individually. I now need to merge them together in order to have one big video file for a given event.
The duration of the video is important as I need to create some kind of index for someone to be able to go directly to that video sequence without having to look at the whole thing.
When I do a File “Get info” command a window appears with all the information that I need.
Is there a way to gather using AppleScript :
1 - the Name without the extension “filename” and
2 - the Duration “00:32”

Edited to take care of a possible null value returned as duration.
Edited to return duration as min:sec ( thank you Shane )

Here’s an alternative that lets Spotlight do more of the work. Requires 10.10 or later:
use AppleScript version "2.4" -- Yosemite (10.10) or later
use framework "Foundation"
use scripting additions
-- choose folder and make URL
set theFolder to choose folder
set theURL to current application's |NSURL|'s fileURLWithPath:(POSIX path of theFolder)
-- start Spotlight search
set thePred to current application's NSPredicate's predicateWithFormat_("%K CONTAINS %@", current application's NSMetadataItemContentTypeTreeKey, "public.movie")
set theQuery to current application's NSMetadataQuery's new()
theQuery's setPredicate:thePred
theQuery's setSearchScopes:{theURL}
theQuery's startQuery()
repeat while theQuery's isGathering() as boolean
delay 0.01
end repeat
theQuery's stopQuery()
-- set up results array, formatter for duration
set theResults to current application's NSMutableArray's array()
set theFormatter to current application's NSDateComponentsFormatter's new()
-- loop through results
set theCount to theQuery's resultCount()
repeat with i from 1 to theCount
set aResult to (theQuery's resultAtIndex:(i - 1))
set theName to (aResult's valueForAttribute:(current application's NSMetadataItemDisplayNameKey))
set theDuration to (aResult's valueForAttribute:(current application's NSMetadataItemDurationSecondsKey))
try
set theDuration to (theFormatter's stringFromTimeInterval:theDuration)
on error
set theDuration to "unknown"
end try
-- format values tab-delimited
(theResults's addObject:(current application's NSString's stringWithFormat_("%@ %@", theName's stringByDeletingPathExtension(), theDuration)))
end repeat
return (theResults's componentsJoinedByString:linefeed) as text
Edited to deal with files lacking the duration metadata.
set thePaths to AST list folder ((choose folder) as string) matching regex "\\.(mp4|mov|webm)$" with returning HFS paths
set report to "filename duration"
repeat with aPath in thePaths
set metadata to ((AST metadata for file aPath) & {kMDItemDurationSeconds:0})
set duration to kMDItemDurationSeconds of metadata as integer
set basename to kMDItemFSName of metadata
-- remove extension
set filename to (AST find regex "(.*)\\.(.*)$" in string basename regex group 2) as string
-- convert time
set sec to text -2 thru -1 of ("0" & duration mod 60)
set theTime to text -2 thru -1 of ("0" & duration div 60) & ":" & sec
set report to report & return & filename & tab & theTime
end repeat
In case you need to get the path attached to the returned datas (as is done by my original script) you may edit the second loop of Shane’s script this way :
repeat with i from 1 to theCount
set aResult to (theQuery's resultAtIndex:(i - 1))
set thePath to (aResult's valueForAttribute:(current application's NSMetadataItemPathKey)) # ADDED
set theName to (aResult's valueForAttribute:(current application's NSMetadataItemDisplayNameKey))
set theDuration to (aResult's valueForAttribute:(current application's NSMetadataItemDurationSecondsKey))
try
set theDuration to (theFormatter's stringFromTimeInterval:theDuration)
on error
set theDuration to "unknown"
end try
-- format values tab-delimited
-- set thePath to (POSIX file (thePath as text)) as text # If you want to convert it into Hfs path
(theResults's addObject:(current application's NSString's stringWithFormat_("%@ %@ %@", thePath, theName's stringByDeletingPathExtension(), theDuration))) # EDITED
end repeat
CAUTION. I added an instruction which may be enabled if you want to get Hfs path of the files. It may be useful if a component of the Hfs path contained a slash which is automatically replaced by a colon in POSIX format.

As the list of names and durations is not linked to a list of paths, it would be difficult to retrieve which file has a given couple of datas.
If a folder contain a file named trucmuche.mov and a file named trucmuche.mp4 how will you identify which one own the couple {trucmuche, 2:34} and which one own the couple {trucmuche, 1:23} ?
It’s why I took care to return the three values for every file.
More, with Shane’s code - which is recursive - we may have different files with the same name in several subfolders.
But maybe it doesn’t make sense for the asker.
I just choose to play safe.

OK, I’ve taken the first code provided by Yvan and ran it on a local folder and the result was OK. However, running the same code with the data located on a NAS did not work. The duration is set to null.
More than likely, the video files are going to be on an external drive. Bizarre, when looking at the directory path everything is correct. Why would that be ?
THANKS AGAIN!

All the alternatives here rely on Spotlight, which won’t index your NAS disks. In fact, I think you will find that Get Info also fails to get the duration of files stored on your NAS disks, for the same reason.
You can, however, get it using AVFoundation. This script requires 10.11 or later:
use AppleScript version "2.5" -- 10.11 or later
use framework "Foundation"
use framework "AVFoundation"
use scripting additions
-- get files
set theFolder to choose folder
set theURL to current application's |NSURL|'s fileURLWithPath:(POSIX path of theFolder)
set fileManager to current application's NSFileManager's defaultManager()
set {theFiles, theError} to fileManager's contentsOfDirectoryAtURL:theURL includingPropertiesForKeys:{} options:(current application's NSDirectoryEnumerationSkipsHiddenFiles) |error|:(reference)
-- eliminate non-video files
set thePred to current application's NSPredicate's predicateWithFormat:"pathExtension IN %@" argumentArray:{{"mp4", "mov", "webm"}}
set vidFiles to theFiles's filteredArrayUsingPredicate:thePred
-- set up results array, formatter for duration
set theResults to current application's NSMutableArray's array()
set theFormatter to current application's NSDateComponentsFormatter's new()
-- lop through
repeat with aFile in vidFiles
-- get localized name
set {theResult, theName, theError} to (aFile's getResourceValue:(reference) forKey:(current application's NSURLLocalizedNameKey) |error|:(reference))
-- create an AVAsset so you can get duration
set theAsset to (current application's AVURLAsset's assetWithURL:aFile)
set durationInfo to theAsset's duration() -- returns record like: {value:2911360, timescale:1000, flags:1, epoch:0}
if durationInfo is missing value then
set theTime to "unknown"
else
-- calculate duration in seconds and format as string
set theDuration to (value of durationInfo) / (timescale of durationInfo)
set theDuration to (theFormatter's stringFromTimeInterval:theDuration)
end if
(theResults's addObject:(current application's NSString's stringWithFormat_("%@ %@", theName's stringByDeletingPathExtension(), theDuration)))
end repeat
return (theResults's componentsJoinedByString:linefeed) as text
Exactly, “Get Info” fails to get the duration of files stored on my NAS disks.
I ran the script created by Shane and it now work on my NAS.
I’ll keep working on the script because this is only the beginning.
Many thanks everybody, this was impossible for me to write something like this. I do have a real lack of knowledge when comes to write such AppleScript programs.
If its possible can the text file be saved in the same location when the script prompted in the beginning where I selected the folder that contained the media
Hopefully I have explained what I am looking to do
Here is how to write to text file. But with avi and mkv movies the Shane’s script gives durations=0. I don’t know why. Well, to write durations to text file replace this:
return (theResults's componentsJoinedByString:linefeed) as text
with this:
set aText to (theResults's componentsJoinedByString:linefeed) as text
set filepath to (POSIX path of theFolder) & "myMoviesDurations.txt"
set openfile to open for access filepath with write permission
write aText as «class utf8» to openfile
close access openfile
