Adding meta data to MP4 video files?

[JoeBG]

why tg? it seems to produce borked .mp4 files
I´m only interested in the use of commandlines.

I´m only interested in the use of commandlines.mp4tags.exe is also a cmdl tool...

[JoeBG]

mp4tags.exe is also a cmdl tool...

Sometimes I´m a little stupid => problem solved :)

so you use "placeholder characters" instead of the really wanted characters, right?
basically no...even if it was true, how can we know all these placeholder characters ? And regarding the code, a just "replace to" will be not very efficient imo.

Shortly, how my function works : first, I grab the length of the string. Then I play with bytes..;) More details here (http://www.cl.cam.ac.uk/~mgk25/unicode.html)...

the only html editor i know is the text editor and this doesnt show me these placeholders ;)
what tool exactly can i use for finding these?
Mozilla, nvu, dreamweaver...and probably some others.

Hi Kurt,

How does the "picture" linking work.... are there any players that can make use of it?

Plus....I've noticed that both iTunes and mp4UI offer a couple more tagging options: -

Can these options be added to MP4Tagger?

Why don't you all just use Winamp (latest version) and give Kurtnoise a break? He has enough to do with BeLight/YAMB. Winamp does the job perfectly.

And Kurt's tagging tool could hopefully grow into someting very useful to us all

Hi,

only iTunes and Winamp as far I know...maybe fb2k too with some extra plugins.

sure...but are they really interesting ?

btw, I've some idea to extend this tool : grab some infos from the input files, a masstagger using a freedb like, patches mp4tags to extend utf8 reading/writing...So, pray to have something before 2020 !!! :D


@Elias: Winamp mp4 tagging works fine with video files ?

How far do you think your MP4 Tagging tool can go?

Could it be used say, to add or even re-name existing chapters, re-name existing audio streams, re-name existing subtitle streams. Or even adjust some of the container level settings within MP4 A/V files?

By-the-way... Here's a prototype GUI design I started thinking about around six months ago... Now don't laugh: -

@Elias: Winamp mp4 tagging works fine with video files ?Yeah. All standard compliant mp4 files work great.How does the "picture" linking work.... are there any players that can make use of it?How do I make use of this? Can Winamp tag like this?By-the-way...

I don't see anything to laugh about. Great GUI.

I've no idea...

I'm ok with add but not with re-name...for me this is useless.

sounds good indeed...;)

And here's another "slightly updated" GUI design proposal: -

What about MP3Tag (http://mp3tag.de/)? It supports MP4.

[Kurtnoise]

but only audio files...

@SMD: what IDE did you use to create this ?

[SeeMoreDigital]

What about MP3Tag (http://mp3tag.de/)? It supports MP4.You're not wrong... In-fact it seems to support tagging for loads of file types ;)


Cheers

[smok3]

yep, mp3tag seems to work fine with mp4 video files as well (well, it shouldnt matter anyway.)

[SeeMoreDigital]

SMD: what IDE did you use to create this ?I use HyperSnap to create these GUI design proposals ;)

Shame it can't be used to create interactive GUI's :eek:


Cheers

[Kurtnoise]

mp3tag doesn't work for me with my weird sample (3 video tracks/3 audios tracks/subs/chapters...yeah, it's just a test sample :p ). But, it works fine with mp4 audio files.

Shame it can't be used to create interactive GUI's
what you mean by interactive ? You must code something to have some interactivity. :p

I know this thread is ultra old and that there is a FAQ about tagging mp4 files using iTunes style BUT the tools listed in the FAQ either does not work well (i want to name the tags eg. iTunMOVI myself) or are not available anymore (mpeg4ip says "NOTE: currently, the tarball is corrupt, and I do not have a way to remake it at this point. Hopefully that will change in a few weeks.").

Is there really no good mp4 tagging tool now after we all use MPEG-4 & mp4? :)

I liked to use mp3Tag just because i can name the tags myself but there is one big disadvantage of mp3Tag. It writes all unknown tags UPPERCASE, thus iTunMOVI gets saved as ITUNMOVI and iTunes does not like that and ignores such tags.

Thanks!

YAMB -> it cannot tag mp4 files using the moov.udta.meta.ilst hierarchy
AtomicParsley - it can only delete such tags but can't write them
MetaX -> it can write such tags but its not free, changes the bitrate info and changes the language setting of audio streams to "English".

[Chetwood]

I'd be interested in that as well, preferably free and for windows ;)
