"By default ffmpeg includes only one stream of each type (video, audio,
subtitle) present in the input files and adds them to each output file..."
You have requested -newvideo and -newaudio leading to 2 video and two
audio, but you are trying to map two videos and 4 audios...
Do you really want the video twice?
try .... -map 1:v -map 0:a -vcodec copy -acodec copy "T:\OUTPUT.mov"
