Synology Video Suggestions

I have three video suggestions:
NUMBER 1: A quick video on Synology photos on Apple TV 4K. It’s kind of basic but the trick is to share your album with the person logged into the Synology. I use an account that can’t edit anything and is just a user.
NUMBER 2: A video on the importance of metadata for Synology Photos. I use MetaImage and EXIF data by Harvey. This could briefly discuss EXIF, IPTC and file formats.
NUMBER 3: Well, when I got my Synology NAS I was not fully convinced to use BTRFS and use an individual format. Now I would not mind reformatting it to the recommended format. I use hyper backup and a method to do a complete reformat and install would be helpful without losing everything I set up.
