I enjoyed the podcast about video transcoding with Don Melton. I downloaded the scripts and have been using them a couple of years to manage the size of my Bluray library. However I recently upgraded to High Sierra and I believe Xcode also. I am not a script guru so I took the scripts as they were posted. However now the detect-crop script no longer runs. I get an error message
-bash: /usr/local/bin/detect-crop: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby: bad interpreter: No such file or directory. When I search for the folder for ruby, I see I have a 2.3 folder but not a 2.0 folder and wondering if it has something to do with the upgrade? Not sure where to look now. Thanks, Mark
