How do I select mp3 output in VRD6?

I remember asking about this back in the v5 days and was told it was coming to v6 (still trying to find the post).
I cannot find it in the v6 profiles, if it's there please point me in the right direction.

USE CASE
I get H.264 w/AAC-LC mp4's and using VRD6 cut and save them using same codec. Works great.
After that I use Pavtube video converter to create an mp3 audio only file that I import to my iPod Touch and iPhone.
These are 128 kb/s, 2 channel, 44.1 kHz AAC-LC that I convert to 96 kb/s, 2 channel, 44.1 kHz mp3's.
Will soon be replacing my Win-7 computer with a new Win-10 computer and don't want to continue using Pavtube on Win-10 for only this use case.

I occasionally need to strip out the audio from a video file and have used a freeware program called Xmedia Recode which seems to have the options you are looking for, MP3 and the ability to set output parameters. Granted not a one-stop VR6 but given the availability of such conversion tools....

mp3 audio is not a mainstream codec for video, nor does it have broad device support.
Both AAC and even AC3 are newer, more efficient, and have superior high-frequency retention.
If your iThingies do not play your source AAC, something is quite wrong, because Apple invented the mpv/mp4 format.

Still doesn't answer my question of how do I output mp3 in VRD TVS6.
I already edit and save the video in VRD and don't use that for my iThingies.
I want to skip the extra step of using other software to create an mp3 audio only copy of that.
Just for clarification, I'm not asking HOW-TO preserve audio details, I'm already doing what I want to do with an extra step.

My iThingies do accept AAC, but there are other issues with that which is why I have imported mp3's to them for years.
I have tagged my mp3's for import to my iThingies chosen podcatcher app which makes them look like podcasts and has a whole lot of other benefits I use.
I'm not looking to change the way I use my iThingies and apps, I'm simply asking...

Does VRD TV Suite allow saving/exporting mp3 audio only? YES/NO
If NO, can it be easily implemented? YES/NO

PERIOD, Thank You

I missed the word "only," please forgive my misreading.
m4a would be a better choice if it were offered, since it is faithful to your source format, and would not degrade further.

M4A IS what VRD saves the audio to IF you select the "Audio Only" profile. I have been doing that for years. But since I too have nearly 10K audio files in my library that are all mp3 I don't want to mix m4a files in there. So I too use a 3rd party conversion program prior to sending my audio files to my MP3 players. I also concur that VRD should offer an MP3 option. Perhaps in the advanced options there can be an additional option that says "Output AAC as MP3" in addition to the way it is now as "Output AAC as M4A."

I have hundreds of "tagged" mp3's I've imported to my iPod/iPhone/iPad and use a podcatcher app to import them.
I've never found a way to tag AAC or m4a with metadata I want for import to them.
I don't care too much about the audio quality as it's just speech and not music.
I prefer to reduce the file size so I can fit more on my devices and settled on mp3, 2-channel, 96.0 kb/s @ 44.1 kHz.

Great minds! That is exactly how I save my files. And mine ARE all music and I will openly admit that with my high frequency hearing loss (too many Black Sabbath concerts when I was young), my music sounds perfect to me with those settings. And you're right file sizes are smaller and tagging works better. I hope the VRD folks find the time to add the MP3 format. Thanks for providing peer support.

There is a unique issue with MP3 support and VideoReDo. I could easily add an MP3 encoder to VRD for output. In fact it's sort of already there from testing I did a while back. The problem is opening those files in VideoReDo. Unlike every other audio format in existence MP3 uses variable frame durations. VideoReDo can not handle this at all. It would screw up not just the syncing logic, but the UI. So if I added MP3 output support and then you attempted to open one of those files in VideoReDo it would open the audio as an uncompressed LPCM stream. We haven't decided if this is acceptable behavior or not.

But if you added an audio only output option in MP3 the opening issue in VRD wouldn’t apply, you just wouldn’t / couldn’t.

EXACTLY what I was just typing. Put it ONLY on the Audio Output profile! No one would ever think to open an audio file with VRD, right? This REALLY would help all of us music lovers who still use MP3 players. For example, ABC just put on The Little Mermaid Live. My grandkids wanted just the songs from the show. Although VRD could extract them, I had to convert all of the VRD M4A's to MP3's just to put them on their MP3 players. Please reconsider.

Thanks,

Yes, please add mp3 as an Audio ONLY output and not allow importing of mp3 ONLY or video with mp3.

I already have the H.264/AAC video edited and saved, the next step is output an Audio ONLY mp3.
As long as I can define the sampling and bitrate I would be happy, although I mostly output 2-channel, 96.0 kb/s @ 44.1 kHz
