Hi again John,Sorry Dave - the splitter will not convert your files to AVCHD. It will (hopefully) allow you to bypass the cameras “block” on outputting HDMI to a recording device. This means you can use the Mypin to record them from HDMI, but these will (as you know) be in MP4 format.
To get the Panny to burn them to disc (after importing them to it’s HDD) they need to be in the AVCHD format first. The only way to do that is to pass the MP4 files created by the Mypin through a software converter and transcode them to AVCHD (I think).
If you have a computer, there are plenty of free solutions to convert MP4 to AVCHD available online
When you say "If you have a computer", will my Windows 10 laptop have the power to run this software to do the job of converting my MP4 files to AVCHD, or would it require a desktop do you think?
Sorry about my silly mix-up earlier John, I do get in a muddle at times, but actually I do understand the required sequence of processes you explained to me, it was just a temporary stress induced aberration, lol.
