Copy meta information base on file duration of a Video

[mspmizo]

i use Adobe Media Encoder to convert my videos to a different format, i notice that all the metadata tags(XMP) are cleared after the conversion, i put the original videos in a "original" folder and put the converted videos into a "converted" folder. I want to copy all the metadata from original videos to the converted video bulk, the converted names were change too, so i was wondering if i could match the videos (original and converted) by their duration to make accurate metadata copies individually to recover the original metadata as i want to delete the original videos after i copied it to save disk space.
I need a command line to do that
I use windows 10 exiftool
please help! i am a beginner.
