This is my workflow for packaging and sending RW-570 broadcasts:
Get the raw broadcast materials. Do whatever I need to collect it.
Open the Siri Shortcuts editor on whatever device is available. Edit the “Metadata Moval” shortcut to contain the metadata of the broadcast.
If the broadcast was recorded through a screen recording & is being packaged entirely from my phone, input the broadcast material into the shortcut through the share sheet.
If the broadcast was recorded from the Nintendo Switch, send the video to my laptop to be re-encoded before being packaged.
If the broadcast is already in audio format & is being packaged from my laptop, run the shortcut and pull the material from there.
If the broadcast is being packaged ahead of time using my phone, save it to the Downloads folder when prompted, and transmit it to my laptop when available.
If the broadcast was packaged from my laptop, or when the pre-packaged broadcast is sent there, proceed with the process.
Upload the file and submit it to ChanRec or Corkboard, whichever one is currently operational.
. . . While writing this, I realized that very few people would know what I'm talking about. This is a very convoluted process with some chances for streamlining, but there are some silver linings to this system, such as consistent metadata between broadcasts being packaged in bulk.
