Thanks for answering! I read the article and did some trial and error, but it didn't work. What I'm currently trying to do is create a broadcast commercial using ffmpeg. I did two things but they didn't work. First, I transferred the MXF file to the XDCOM XDS-PD200, but it was not displayed. Second, I used Sony MXF format checking tool which can check MXF files, but it showed an error message. https://www.sony.jp/xdcam/support/download/pwa_mc1.html
When I check the MXF file generated using the code below, I get the error message "The MXF metadata contains an unspecified value". Please advise as I don't know what is wrong. %~dp0ffmpeg\ffmpeg.exe -i temp\temp2.mxf -i temp\narr3.wav -i temp\narr3.wav -i temp\silent.wav -i temp\silent.wav -i temp\silent.wav -i temp\silent.wav -i temp\silent.wav -i temp\silent.wav -c:a pcm_s24le -ar 48000 -map 0:V -map 1:0 -map 2:0 -map 3:0 -map 4:0 -map 5:0 -map 6:0 -map 7:0 -map 8:0 -vf copy,il=l=d:c=d,colorspace=fast=1:all=bt709:format=yuv422p:ispace=bt709:itrc=bt709:iprimaries=bt709,il=l=i:c=i,fps=29.970,setfield=tff,setdar=dar=16/9,setsar=sar=1 -field_order tt -top 1 -flags +ildct+ilme -alternate_scan 1 -g 15 -timecode 00:59:45:00 -c:v mpeg2video -r 29.97 -pix_fmt yuv422p -aspect 16:9 -color_range 1 -color_primaries 1 -color_trc 1 -colorspace 1 -non_linear_quant 1 -dc 11 -intra_vlc 1 -qmin 1 -lmin "1*QP2LAMBDA" -qmax 28 -lmax "56*QP2LAMBDA" -b:v 50000000 -minrate 50000000 -maxrate 50000000 -minrate 50000000 -bufsize 17825792 -bf 2 -metadata creation_time=now -vtag xd5c -intra_matrix 8,17,17,19,17,19,21,21,21,21,21,21,23,22,23,24,24,24,24,24,24,24,25,25,25,26,26,26,29,29,29,26,26,26,25,25,27,27,28,29,29,29,31,32,32,31,31,30,30,33,33,34,34,34,38,38,37,37,43,43,44,50,50,58 -inter_matrix 16,17,17,18,18,18,19,19,19,19,20,20,20,20,20,21,21,21,21,21,21,22,22,22,22,22,22,22,23,23,23,23,23,23,23,23,24,24,24,25,24,24,24,25,26,26,26,26,25,27,27,27,27,27,28,28,28,28,30,30,30,31,31,33 -f mxf -y output/output.MXF silent.wav is a sileent file.
