Hi. There is no strange structure about that. The fact is that corresponds to a XDCAM file footage, where the real video file is 972_1389_01.mp4, and the others are SONY propietary info files, that records metadata concerning the footage.
If you want to convert the file with ffmpeg (for instance if your NLES doesn´t accept mp4) you can try this batch script con windows or bash in linux:
ffmpeg.exe -i "INFUT_FILE_NAME.mp4" -threads 2 -vcodec dvvideo -s 720x576 -r 25.00 -threads 1 -pix_fmt yuv420p -g 300 -qmin 3 -b 2048k -async 1 -g 300 -acodec pcm_s16le -ab 1536k -qscale 10 -aspect 16:9 -y "OUTPUT_FILE_NAME.avi"
