Audio Tagging
Hi! I have been tasked to generate an Apple ProRes422 export according to provided specs, and got stuck when it comes to this requirement:
“AUDIO TAGGING
Audio should be tagged with descriptive data. This information should be available when
using media info and can be added to a file in a variety of ways. An example of audio tags
for a 10-channel file is below.”The example is a screencap of a list of channels and their information, the first two entries read like this:
“Channel 01: Left 00:00:00:00 00:05:41:05 46.83MB Left Integer (Little Endian)
Channel 02: Right 00:00:00:00 00:05:41:05 46.83MB Right Integer (Little Endian)”I guess my main question is I don’t know how to generate an export with Premiere with the name of each audio channel embedded into the export so that it can be displayed as part of the media info. I have been testing my export with VLC / Quicktime, and the audio channels are only displayed as “1, 2, 3….” instead of “Left, Right, Center, LFE…” even though I have named my audio channels inside Premiere.
Any help will be most appreciated. Thank you!!!

Are you referring to the Audio Source or output where its displayed when you are about to export a video in premiere pro?
For example, my Source Audio is 48000 Hz | Stereo and the one for Output Audio is AAC | 320 kbps | 48 kHz | Stereo
Or is it somewhere else? Hope to hear back from you soon!

Thanks for your response. I believe what the specs refer to are metadata embedded in the export, so that when the export is loaded onto a player, the player can display (in like the media information window in VLC) the name of each audio track (e.g. Left, Right, Center…)
There is a metadata function in Premiere but I don’t see any that allows you to name audio tracks.
To clarify, I think they are talking about metadata embedded in the file as opposed to data burn-in baked into the video.

Thats interesting, I will need to check the metadata option later on when I can. Are you also referring to the audio data that you can look what kind it is with the right-click and properties option of a specific audio or video file?

Thanks Hector. The specs actually didn’t state what they are using to read this metadata. I imagine whatever is common. I only have VLC and right click + properties to test it at home though. Right now I think in VLC, the audio tracks are just stated as 1, 2, 3, 4, etc… I think ideally what they want is that it will read L, R, Center, etc.

Ahh okay I see, if you are able to send me a screenshot of the Audio properties of that video file, maybe I can see if where I was looking at for you was the correct place. And depending on the audio settings it had before you rendering, it should be why the audio reads that way in properties.

Thanks — actually I’m not even sure where and how I’m supposed to look at those track names. I am basically just trying to satisfy the requirement in the specs as duplicated at the top of the thread. I just need to deliver this file with the audio tracks info embedded in the file, and I have not been provided with the means to check it (’cause it will be checked by the streaming platform team), and the specs do not specify with what they will read that embedded information.
I basically have not generated the export yet, but I’m pretty sure whatever export I generate as of now, the audio tracks will not be named L, R, Center, etc. no matter what I use to check it because I have not embedded that information into the file in Premiere, and I’m trying to find out how to do that with Premiere.
