Default Does .mp4 - or any other video format - have a text field (comment, not subtitle)? If so, what can edit it?

Cross-posted to 4 newsgroups. Many netizens consider that excessive.
How is a broadcast newsgroup related to metadata in files?

I like the comment field in the .jpg image format; if viewing an image
in IrfanView, I just type I then C, and I can add comment text, that
then actually becomes part of the file, thus surviving any renaming,
zipping, even emailing. (I use it a lot in listing who's who in group
photographs [I come across those a lot in genealogy], but general
information about an image is useful.) [I _presume_ there are other
image-handling softwares that can access/edit this field, though I don't
know what they are; I'd be interested to know.]

I'd like to have a similar facility for videos (I have mostly .mp4
format, but am interested for any format): _is_ there something
intrinsic to the format? I'm not talking about a subtitle "track", or
anything like that - just a comment field. And if there is, what
software can access - and/or edit - it?

At present, I'm reduced to either putting information into the filename,
or keeping a text (or other, such as .doc - I only use that for the one
or two places I want to e. g. include some Russian) file of the same
name in the folder next to it. Both of which are unsatisfactory compared
to an embedded text field.

Says it edits metadata in files, and lists .mp4 as a supported format.
It's free, so you could try it without cost.

That has a pic at step 2 showing what metadata fields can be edited for
an MP4 video.

Even if a graphics file format does not support metadata or comments,
you could use steganography to encode your comments into the graphics
file. Probably a lot more work than you care to perform, especially
since you did not indicate the comments are secret.
