[FFmpeg-user] MXF with XDCAM HD422

[Alex]

Hi all,

I want to encode a prores 422 file (1080p/25) to MXF with OP1a (SMPTE 378M).
Compression should be a XDCAM HD422 (MPEG2) with 4:2:2, 50 Mbit/s and
Long-GOP. I tried the following and got several error messages:

Command:

ffmpeg -i test.mov -pix_fmt yuv422p -vcodec mpeg2video -non_linear_quant 1
-flags +ildct+ilme -top 1 -dc 10 -intra_vlc 1 -qmax 3 -lmin "1*QP2LAMBDA"
-vtag xd5c -rc_max_vbv_use 1 -rc_min_vbv_use 1 -g 12 -b:v 50000k -minrate
50000k -maxrate 50000k -bufsize 8000k -acodec pcm_s16le -ar 48000 -bf 2 -ac
2 -f mxf_d10 output.mxf

Output:
