Just going through the options on Format; if I choose 'Quicktime'... and then Preset 'H.264' - I do then get the option to export uncompressed audio...

Best way?

To achieve this, you would have export the video and audio separately and use a third-party muxer to combine the two into one file.

As above - you can export uncompressed audio using H264 codec - as long as format is QuickTime. Or am I missing something?

See screenshot:

Only issue now is - I just tried an export and..... silence!!! Why am I not getting any audio at all? Exporting in another format; the audio is there - but not in the export setting I need (H264 but with uncompressed audio...)

Any tips or advice?

A guiding principle that I've had a lot of success with is: Don't use QuickTime if you can avoid it.

That leaves my earlier suggestion as the only option, I think.

QuickTime has been the cause of many issues.  Gamma shift and unresolved bugs are two.

Wow; all news to me. Thank you for that.

And so the dilemma now is... seeing that YouTube actually recommends 24 Bit 44.1 WAV as the audio (for music videos) - how best to upload a video to YouTube with 24 Bit 44.1 uncompressed audio?

If I want to stay using H.264 - I have no choice but use QuickTime (if I want 24 bit audio). Otherwise, if I want to use H.264, I have no choice but to compress the audio (ouch!).

*note 24 bit WAV.

In the Export Settings dialog box, set Format to H.264. For the Preset, choose YouTube 1080p HD. That's supposed to be supported by YouTube, so see if it works for you.

Thank you, yes that would work - but it will be compressed audio still: AAC - rather than uncompressed 24Bit WAV - which is what I'm aiming for. I will keep experimenting!

how best to upload a video to YouTube

I recommend using DNxHD rather than H.264.  The audio is Uncompressed, which means no sync errors.  (2017 introduces a slight sync error with all compressed audio formats.)  And the final YouTube-transcoded quality is a bit better.

I will check that out today! Thanks.

I'm approaching the point wherein - I will export as H.264 with compressed audio (as YouTube suggest on their general formatting pages). And then again in QT H.264 with raw 24 bit audio - and then again with your suggestion of DNxHD...

I will then upload all three versions to YouTube - and whichever looks (and sounds) best - will stay up and and other two, I will delete.

Apologies - but upon going through the motions here; I note that the filetype for DnxHD is '.mxf' - which YouTube does not allow... how to get around this - I assume I've missed something?

Thank you

Can you rename the file with .mp4 and upload it?

Old thread, but this the exact dilemma I have been experiencing. I upload much of my own music to YouTube in H264, and not so much video but my audio sounds drastically more compressed when I listen to the original file.

The reason for this is when you upload a lossy file, YouTube is transcoding a lossy format to another lossy format.

I actually have a clip uploaded to my channel that sounds distorted, and this week I am going to work on exporting an uncompressed 10bit file and putting it into my own compressor to DNxHD.

I am going to do the blind test and will post on here my side by side comparison in a few weeks.
