I'm running an AppleScript that finds a video's resolution via ffprobe and appends it to the file name. No problem with ffprobe or building the new file name, but adding the extension back onto the file name is failing. Any advice?

Code: Select all

tell application "Finder"
   
   -- get filename and extension
   set theEpisodeName to name of theFile
   set theExtension to name extension of theFile
   
   --get the filename without extension
   set theEpisodeName to text 1 thru ((theEpisodeName's length) - (offset of "." in (the reverse of every character of theEpisodeName) as text)) of theEpisodeName
   
   -- get video resolution
   set theEpisode to quoted form of POSIX path of theFile
   set theWidth to do shell script ("/usr/local/bin/ffprobe -v error -of flat=s=_ -select_streams v:0 -show_entries stream=width " & theEpisode & " | cut -d \"=\" -f2")
   set theHeight to do shell script ("/usr/local/bin/ffprobe -v error -of flat=s=_ -select_streams v:0 -show_entries stream=height " & theEpisode & " | cut -d \"=\" -f2")
   set theResolution to space & "(" & theWidth & "x" & theHeight & ")"
   
   -- build new filename with extension
   set newEpisodeName to theEpisodeName & theResolution & "." & theExtension
   set name of theFile to newEpisodeName
   
end tell

Are the dimensions not already available via metadata? If so, it might be easier to use that. Otherwise, I'd recommend exporting custom attributes back out to Hazel. You can then use those in the Rename action.

Maybe? I didn't see an option for selecting width/height amongst available renaming attributes. The closest I can find is "Resolution (width/height): Resolution (width/heigh) of this image in DPI"

Is the Dimensions attribute not suitable in this case?

Hmm. I'm not seeing that as an available attribute when I search attributes after clicking 'other' in the rename field.

If you select the file in Finder and do "Get Info", do you see it under "More Info"?

For MP4 videos: yes
For MKV videos: no

Guessing that since MacOS doesn't natively support MKV files that any OS-level solutions won't work here?

It depends on the apps you have installed. You can try and search around for an app that handles mkv that also provides a Spotlight importer that will provide that info to the system.

I've just installed Filebot (which can handle MKV metadata) and can call it from the command line. Rolled it into my Hazel action and it's working perfectly. Thanks!

Hi, can you share how do you did these, please!

Sure. Here's what my action and embedded shell script look like.

I also recommend taking a look at documentation for the Filebot CLI. Note also that Filebot requires a license.
