Ups there was still the "-an" in the first pass.
Correct Command:
ffmpeg -y -i test.mxf -filter:v yadif -s "1920x1080" -aspect 16:9 -r 25 -b:v
8000k -bt 8000k -vcodec libx264 -pix_fmt yuv420p -f mp4 -pass 1 -strict
experimental -c:a aac -b:a 320k -ac 2 -ar 44100 -ss 00:00:00 test.mp4 &&
ffmpeg -y -i test.mxf -filter_complex "[0:1] [0:2] amerge" -filter:v yadif
-s "1920x1080" -aspect 16:9 -r 25 -b:v 8000k -bt 8000k -vcodec libx264
-pix_fmt yuv420p -f mp4 -pass 2 -strict experimental -c:a aac -b:a 320k -ac
2 -ar 44100 -ss 00:00:00 test.mp4
Output:
C:\video_testing>ffmpeg -y -i test.mxf -filter:v yadif -s "1920x1080"
-aspect 16:9 -r 25 -b:v 8000k -bt 8000k -vcodec libx264 -pix_fmt yuv420p -f
