Is this a bug, or expected behaviour? When converting materials from PAL to NTSC I invoke atempo as follows:
-map 0:a:? -af atempo=24000/25025 ^
-c:a pcm_s24le
I use this in a windows batch file (hence the caret) as a catch-all for all files that need to be converted, not having to deal with how many audio channels might be present or in what order.
However, when my input was a broadcast MXF with 10channel mono audio (1 per stream) it introduced wild phasing between the tracks.
Merging the tracks into a single stream to be processed by atempo resulted in no phasing.
-filter_complex "[0:a:0][0:a:1][0:a:2][0:a:3][0:a:4][0:a:5][0:a:6][0:a:7][0:a:8][0:a:9] amerge=inputs=10, atempo=24000/25025[FRC]" ^
-map "[FRC]" -c:a pcm_s24le
Is this expected behaviour? I can't see any documentation detailing the need to first use amerge before invoking atempo.
If indeed this step is necessary, is there a way to "wildcard" the amerge operation so that I don't have to manually enter all the audio channels, and then the "inputs="? This would allow me to make it more universal.
This is my first question on stack overflow, so please be gentle. I've come here to find so many answers to my FFMPEG questions in the past--but this seems to be an edge case I can't get much detail on.
Thanks!
EDIT:
This output using the wildcard produces phasing:

Let me know if you need more detail than what I've provided.
EDIT2:
This thread seems like it might hold the solution to my problem:
How do I use ffmpeg to merge all audio streams (in a video file) into one audio channel?
But I don't have enough reputation to respond there in the comments.
When adding the call to ffprobe in a batch file I can't seem to call %~1, %~n1 or %~fn1.
Batch file:
@echo off
SETLOCAL
SET "Container=mov"
:hugly
if "%~1" EQU "" goto mugly
SET "FFREPORT=file=%~n1%~x1.%container%.log:level=32"

EDIT 3
the following command line outside of a batch file returns the same errors:
ffmpeg -ss 00:10:13.0 -r 24000/1001 -i test.mp4 -t 00:00:22.0 -filter_complex "[0:v]scale=w=1920:h=1080:force_original_aspect_ratio=1,pad=1920:1080:(ow-iw)/2:(oh-ih)/2[video];[0:a]amerge=inputs=$(ffprobe -loglevel error -select_streams a -show_entries stream=codec_type -of csv=p=0 test.mp4 | wc -l),atempo=24000/24024[audio]" -map "[video]" -c:v prores_ks -profile:v 3 -vendor apl0 -pix_fmt yuv422p10le -map "[audio]" -c:a pcm_s24le "G:\%~n1_25to23976_test44.mov" -y
I'm going through the ffprobe commandline entry by entry but I'm uncertain what function the "| wc -l" is performing as the ffprobe manual doesn't have an entry for "wc".
It seems this is a counting function within linux. This is likely why my command is failing!
