Can anyone recommend a decent metadata editor for MP4 videos for Mac? I need to add metadata information such as Movie Name, Genre, Release Date, Cast Members, Sort Name etc, as well as poster image. I understand a lot of video convertors include metadata editors built-in which is fine, although I'm not interested in the video conversion feature. But a lot of the apps I've found so far are either no longer supported or just don't work particularly well - iVI Pro, iFlicks 2, iSkySoft iMedia Converter - which really surprises me to see a lack of metadata-editor software for the Mac. It would also be great if I could find one that supports file creation/modification date overrides as well, as I currently have to use the setfile tool in terminal which works, but is rather cumbersome to use for lots of files. Any recommendations would be appreciated.
