I'm developing a software which is called EnKoDeur-Mixeur (developed
in Python) that allows (among others) to do what you ask.
EnKoDeur-Mixeur uses FFmpeg commands to transcode AVCHD files to other
formats, this is an example:

commande linux_dependances_portables/ffmpeg/ffmpeg -i
"/home/angelo/blender/billes.mts"  -s 854x480 -codec:v prores
-profile:v 3 -codec:a pcm_s16le -threads 4 -y
"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_pro_res_mov_00001.mov"
