Problems with automatically obtaining metadata

When I use the NAS local network connection to set up the SMB protocol and FTP protocol, I have to capture or reset the video interpretation data of the same folder, which is very tiring. Or I have to connect to the external network and enter the WAN IP interpretation data again. Once again...can we make the interface for interpreting data better? Next, can I have Watchos to control the sound volume and fast forward playback function?
