<12darkloke> I have a question about m4a format and muti-valued tags (like composer). I need some Picard script to correctly fill them or this depends on the player to correctly read them?

this depends on the player to correctly read them <- this

darkloke: picard's (or rather mutagen's) implementation of multi-value tags for m4a is incompatible with many players. there is currently no way around that.

essentially how to store multiple values for a tag is not specified for M4A, and there are two unofficial but incompatible implementations. see the discussion on https://tickets.metabrainz.org/browse/PICARD-376

PICARD-376: MP4 multi-value tags are proprietary to Picard/mutagen (?)

if your m4a contains lossless audio, it's maybe a solution to convert this to flac. on level12 compression it produces even smaller sizes...and then retag the flacs

<12darkloke> I found this script for Picard to multi tag m4a on the player's forum, but i see no changes (or cannot implement it correctly). Can someone check it? https://getmusicbee.com/forum/index.php?topic=1...

darkloke: yes, that would generally work if you just want to see the values. it flattens all the specified tags to semicolon separated entries

just note that it e.g. replaces the artist tag, which by default is a string "as credited", with a list of the artist names

similar some other tags

<12darkloke> Ok, but what i need to do to execute it? Just add as script in scripting tab?

I would just have my doubt how universal the file format detection is with "$if($eq(MPEG-4 Audio \(AAC LC\),%_format%),". you should check what this shows for your files in the info dialog inside picard

yes, this gets run then on data in the right pane when loading releases or attaching files to tracks

<12darkloke> It shows me this: Format: MPEG-4 Audio (ALAC) I suppose it differs from what script tries to detect...

well yes, that has "MPEG-4 Audio (AAC LC)"

you could try "$eq(MPEG-4 Audio,$substr(%_format%,12))" for a more universal approach (I hope I counted correctly)

<12darkloke> It works if i simply change (AAC LC) to (ALAC), but doesnt work with your universal approach (if i added it correctly). Anyway, thanks for the help @outsidecontext. 🙂

you're welcome

ah, it should be ""$eq(MPEG-4 Audio,$substr(%_format%,0,12))"

<12darkloke> Aye, now it works! Thank you. If you don't mind can i post this solution/update to this forum? May be it would help someone else.

Sure, please do

<07aszazin> Is there a way or script to transfer all relationships of a Work to the different parts of the work, without editing them all individually?

hmm.. that sounds liek ther is a script.. lete me se

check https://wiki.musicbrainz.org/Guides/Userscripts

Hmm. There is that for releases but not sure about works

hmm

seems liek amodifying one script souldn't bee too hard?

<07aszazin> Sounds like a script is missing!

I think it hasn't been done because in most case you batch-add the stuff to all the parts from the relationship editor anyway and all that is missing is the one parent work

hmm

<07aszazin> Yes, I just had a rare case where the work is first present in parts, and then in one long recording on the same release

<07aszazin> I guess currently the best way is to manually add them through that release

<07aszazin> I am a bit struggling with lots of double data entry, especially recording/performance dates. Or shouldn't I add the recording date for each individual performer?

Ideally yes

There used to be a script that copied them around

I think it might be broken right now

Honestly, I think it's fine to enter them once (possibly in the recorded at place relationship) if the script doesn't work

Have you seen https://community.metabrainz.org/t/the-classica... ? I forget if I already pointed you to it :)

<07aszazin> Yes, I installed most of these scripts

<07aszazin> The "loujine GM tools" has a function to copy dates, but it's not clear to me how to make it work, or what it will exactly copy to where

<07aszazin> Entering them once seems like a good idea.

I think it might be broken

That bit

In theory, you select the recordings, click copy dates, and if one relationship has it it will copy it to the others

<07aszazin> Usually if I post links, I try to archive them and post the archived link somewhere, you know, in case it disappears some day. Where is the most appropriate place to post archived links on MB? In the edit notes? As another URL?

aszazin: adding the link in edit notes is the best option.

there wss a GSoC project this year to automatically archive all external links at the IA, not sure if it got accepted though.
