In the Export dialog, go down to the settings below the Summary panel, click on the Audio tab, and you can select the audio format you want there. On many of the formats you can export video into, there are lossless audio options available.

I appreciate the fast reply, but the options in the audio tab vary depending upon the "format" like h.264

I dont know which format that will allow small video size (compressed), with lossless (uncompressed) audio?

A format that is comptible with most players please.

how will the video be distributed?  compressed audio doesn't always mean loss in AUDIBLE quality...  just like compressed video can look great.    Where high quality compressed audio can have an impact (just like compressed video) is if you need to do additional processing to it.

Its going in a video card broucher, im hoping we can find a format that works in the card and retains the best possible audio.

 

the audio track has been mastered by Abbey Road studios, so i really would prefer to avoid software compression messing up their great work. But if i must, which do fomat/codec do you suggest?

when you say a "video card broucher" can you be a little more specific?  How will the file be played?   I'm all for ekeing out the best possible quality, but unless people will be able to play it on a high end system, it just probably won't make any difference.

and as far as I can tell, most compressed (mpeg) video formats like h264 also require audio compression.    DVD video is one of the few formats that allows for uncompressed aiff audio but the video is limited to standard def and not sure how universal the format would be...

is the video actually in synch with the audio?  If so, the audio can't be mp3 or wav as far as I know.  If video and audio are triggered at the same time, it might be close.   But this card will have a tiny speaker and the quality will not be great, no matter what you do...  unless I'm missing something.  Actually in that sort of situation, high quality audio may not be the best way to go.  Back in the day when we were finishing for vhs distribution, we would try and play back the finished piece on lousy speakers cause that's what most people would be using.  I once had to provide an audio file for some sort of similar card (without video). the audio quality sucked...

sorry i wasnt clear, the card can play those audio formats, OR video like mp4 (i dont know all the formats its supports yet, but it didnt like h.265).

 

The card has only 480mb space,  and video is too large if uncompressed, but wav is only 25mb. Was hoping there was something that would compress video but just leave the audio. Seems like their isnt...

but if it's only playing audio on the built in speaker, it's not gonna be great.  and as I said, higher quality may actually not sound as good on the built in speaker.  Kudos for pushing for the best listening experience possible, but I've been around this block a few times and you may just be spinning your wheels.

Say for H.264, going down below in the Audio tab, it's all AAC. But ... you have options to set the frequency, higher tends to be better Q audio. Also you can set the audio bitrate, and again, higher tends to be better. At 48,000Hz, with audio quality "High" and bitrate of 320Kbps, you'll not have any possible notable degradation.

 

You'll have a large export of course.

 

You can easily test yourself, but doing several exports with different settings. Can you upload/distribute your export as the project will be, and hear any change on a good-quality audio system? If not, well ... that's fine then.

yeah i think my best option is just going to be h.264 + ACC with highest bit rate. Just tested and sounds acceptiable.

 

Thanks also to @mgrenadier

That's actually well above most music CD settings, btw. Yea, it shouldn't be noticeable.

For anyone the finds this thread in the future, I have found using another program (vegas pro + happy otter scripts) i could render to MKV h.264 with FLAC for lossless audio codec. This created a very small file of only 21mb compared to the 1gb file i was getting before. Surprisingly the card supported MKV. As for the audio result, FLAC vs high bit ACC is almost indistinguishable. The trebbile is perhaps minutely different.

 

Unfortunately at this time Premier Pro doesnt seem to support exporting to MKV as far as i can see?

No, Adobe apps do not support Matroska. It's a fine codec but used more in a "niche" of the total video, and for some reason the managers don't find it worthwhile to support it.
