No, because the drive I was going to encode it onto doesn’t appear anywhere (not diskutil or anywhere) after an abrupt disconnect. No data was lost, since it was recently acquired. It appears to be broken. Not a big deal in itself, just means I don’t have anywhere to export the video as ProRes like that. (I’d encode final product streams directly from Compressor anyway.) I tried troubleshooting for a while but it seems dead. It’s my own fault!

I’m not about to delete my Time Machine backup right now in order to do it, but it should be no issue to restore from it. In the process of troubleshooting I had to reboot and it did it once, but the second time put it in its opossum state.
