Pro Res 4K Clip, Is it possible to access AAC Stream

[Donfor39]

2023 2mins iphone 14 Clip, replays using PCM Stereo, using co pilot aka cgpt4, I can list Audio streams via ffmpeg.
Seems I can't Force AAC+Container Compatibility intending to Encode AAC Audio stream.
No Pro Res Codec from #0:0 'Is there any further options'
thanks

I don't understand the use case for trying to encode AAC audio with ProRes 4:2:2 (a DI format). DI formats should utilize PCM multichannel, e.g. Dolby Atmos ADM BWF.

AAC Multichannel is a very unusual format and is not widely supported across consumer electronics and computing devices, as it is a Fraunhofer-IIS product, not to be confused with AC-3 or E-AC-3 which is a Dolby product.

Thanks Co Pilot raised point of
codec pcm_s16le in stream #0 Not Currently supported
Original Audio: LPCM (pcm_s16le), stereo, 48kHz
- Remuxed: AAC-LC, stereo, 192k
- Status: ✅ Compatible

I still don't understand what exactly you are trying to do. You cannot replace ProRes PCM audio with AAC-LC or HE-AAC. Co pilot is wrong or, at best, misleading... You can convert PCM to AAC, yes, BUT you cannot package AAC with ProRes.

If you export as ProRes, the audio will be PCM. If you want it to be AAC-LC, then the video codec needs to be H.264 or H.265, not ProRes.

Thanks as I did ask co pilot if it could be possible to Burn Video Clip via Asus BR External Drive then use MKV to choose another format e.g H.265
t.b.f Co Pilot Did Add .mov .mp4 or .mkv could be used in addition to original script.
Asus BR Drive when reconnected recently does seem very much more supported W11 No More removing 'Initio' From Device Manager.
I'll try mkv this week, thanks appreciated.

Thanks H.264 Ac-3 from Pro Res Pcm.

Final Clean Br Disc Burn inc' Ac-3 Audio. Only PS part that failed was Authorizing Clip before Disc Burn.
Used Leawo Trial and playing perfectly, Co Pilot continues with Alternative Audio suggestions, FFProbe 5.1 maybe.
Edited 5.1 Audio Version Impressive saved to BR disc.
Thanks
