I have been playing with ffmpeg to convert h.264 and h.265 to ProRes and DNxHD. I would like the audio of the ProRes / DNxHD file to be PCM, as PCM works best with the free edition of Davinci Resolve in Linux.
All my source files are from these cameras:
1) Gopro Hero 7, and Gopro Hero 6
2) Panasonic DMC-G80 (DMC-G85)
I plug an external shotgun microphone, and sometimes a Lav microphone into the 3.5mm jack on the Pansonic G80. For the Gopro cameras I just use the on camera audio.
So with the above in mind, what setting should I use in ffmpeg? Should I use:
1) -c:a pcm_s16le
2) -c:a pcm_s24le
Or do I use some other setting for PCM audio in ffmpeg?
Sorry for the very basic question, but I'm not an audio guy!

Check which one works for you best - 24 bit is better than 16 bit thus i would try first pcm_s24le (later perhaps pcm_s24be) if this not work OK then try 16 bit..
