Metadata editor for the Mac

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.

I did this a few years ago. I used metaX. Not a great UI. But it worked for me back then. Its seems to be abandoned on the mac platform but still available. Found Mp3tagger wich supports mp4 etc. There is a mac version "sort of".
Yeah I heard of metaX but I don't believe it's supported under macOS Mojave unfortunately. :-(

The two applications which I've used on macOS Mojave are Meta for audio and MetaZ for video metadata. Other than very minor issues, I've not had a problem with the files being corrupted by the programs after any editing.

MetaZ: https://griff.github.io/metaz/
Awesome, thanks, I'll have a look at these.

I've used Subler for this for a long time. https://subler.org
I've just started using Subler and really like the simple minimalistic-looking interface, plus the fact that I can add just the specific metadata as required, with no unnecessary metadata junk. However I was initially concerned that using Subler would change the video format and/or quality at the same time, i.e. convert or mix down the original video, but have been given some assurance from the developer that it can be used solely as as a metadata editor, and will leave the original video characteristics intact.

I've looked at a number of metadata editors for the Mac and am surprised none of them work with a locally-stored database in order to save personalised cast members, studios, producers, etc - rather than the common procedure of retrieving movie tag information from an online source. I enjoy making my own home production movies that involve amateur cast members and crew, which requires me to manually enter the same text each time, so it would be nice to access retrievable entries from a locally-stored database instead.

But my pick so far would have to be Subler. Thanks for the suggestion.

In Subler you can save a metadata preset or load a xml (I don't remember the exact format). But a locally-stored database would be difficult because there isn't a single database format.
Or you can just keep some mp4 with only metadata in them.

I don’t mean a locally-stored version of the online movie databases, if that’s what you mean.

What I mean is a metadata editor that contains a simplistic text-based repository of all my previously entered metadata entries (of my personalised cast members, producers, genres, etc) that could be re-selected via auto completion as I type in the metadata for my other videos. It could be very similar to how the color tags work on MacOS; it would save each metadata entry that is separated by commas as a text label, such as names of cast members, with the added benefit of adding or removing individual entries from the list as required.

But following your idea - I worked out how to save a metadata preset in Subler, and did the same idea with an mp4-metadata file. The only problem with this approach is that it works as a sort of static text template, rather than like a dynamic selection list as mentioned in the previous paragraph, but it’s definitely better than nothing... and I really appreciate your suggestion as this helps a lot.

Hi,
I have searched for DAYS on this and can't find a solution. Hoping someone can help. I am not too technical, rarely use Terminal.

I have an .mp4 file with lots of data (visible with mdls command) which I want to REMOVE. I want to clear ALL metadata, if that were possible.

I can not find any command for deleting metadata. All I can find is conversations about extended attributes, which are not the same thing at all as the xattr command produces totally different info compared to mdls command.

For instance, I have an mp4 file which has a "wherefrom" metadata field which gives the site I used to transfer it from one machine to another. I like my privacy, so I want to clear this. Is it even possible to do so? It would appear not, which I find incredible, but hoping I am wrong :(

Thanks
