Wanting mp4 with uncompressed audio

[tpprynn]

Hello. I've just put a few things on Vimeo either made or altered from older Windows videos with OpenShot, which I've been using and enjoying for three days. I've just stopped using Windows and Sony Vegas, on which I'd render twice, one version to upload to YouTube and once to save a good copy of the video with Xvid and uncompressed audio. This is because I often add my acoustic guitar to my little video doodles, and that sound suffers worse than any other when compressed and then compressed or converted again on a website. I don't want to save every scrap of each project so a good high quality 720p archive of mp4/avi with wav or the equivalent is what I'm looking for.

When I look at the audio codecs they have the familiar Linux program names' jumble of letters that could say more than the programmer has decided to... So can someone here suggest what combinations of codecs I'd best use to continue renders with very high quality audio. I would like to suggest also that the apparent current 256k upper limit could be pushed further for the other compressed codecs, 320 would be ideal. (Maybe there's something I can tweak in one of OpenShot's files to do this myself?)

Thanks.

I think I'm a bit further with this. I was trying out WinFF and saw that some files I'd put in mentioned pcm_s16le and that's among the OpenShot options. But what are the variations listed? I know the 16 there is 16 bit, but what difference is the codec ending 'le' from 'be' and what difference where the middle is _s16 from _u16?

Apart from having that clarified I think I know what I'm doing now...

Thanks.

Hi,
Just a thought because i have not checked this answer in details and like I am not specialize of Audio.
le for Little endian
be for Big endian
It should be more clear for you than for me.

Thanks. I looked that up and it feels likely that that's what's meant but I don't know if it's something I need to know, it sounds more data-specific than audio-specific. I seem to have found a 16 bit stereo uncompressed audio codec anyway, that's the main thing.

As for compressed audio, it does seem you can just type in 320k where there is only an apparent limit of 256, so that suits me too.

I may look at this thread a few more times in case any important clarification is added by anyone.
