PRORES AUDIO COPY

[backlight]

Good Morning guys,
is very frustrating that I cannot convert to prores file using the -c:a copy syntax

I'm creating some master files in DNxHD444 with some different audio tracks configuration... all in uncompressed format.

I'm trying to somply encode only video in prores.

i turned off video / audio options in the custom node and i'm using this string inside

i'm using this custom

-c:v prores_ks -profile:v 3 -r %f_frame_rate%

In this is working, but it creates a PRORES with AAC stereo file!


HELP!!!!!

Hi backlight,

If you know your source is uncompressed audio (PCM) you should be able to use "-c:a copy". If not you need to use "-c:a pcm_s16le" (for 16 bit, signed little endian). To make sure all source audio tracks follow you need to insert "-map 0" at the beginning of your command line. This will make sure all tracks are sent to the encoder.

-map 0 -c:v prores_ks -profile:v 3 -r %f_frame_rate% -c:a copy (or -c:a pcm_s16le if your source is NOT PCM audio.)

Now it encode without errors... but it give me back a 2.0 stereo file.
It seems not to copy all the tracks on the file (6 different mono tracks)

Can you please share your command line?

This is the command line in custom FFmpeg node... Audio e video codec switched off

-map 0 -c:v prores_ks -profile:v 3 -r %f_frame_rate% -c:a copy

It gives me back a stereo file, if I add the channel selection node it creates a 5.1 file starting from a 6 discreet channels input!
