How to transcode automatically

[Bladefin]

So helpful in what you have said, I have gone into client settings and changed a few things, and now things have changed for the better,I still don't understand all of the settings in the JFMP, but that's what the problem was,I wasn't telling it that it couldn't play it so it wasn't doing anything just sending over the original file.

You have said about AV1 I don't actually have that option ticked in Jellyfin,I have just got Allow Encoding in HEVC format ticked.Is it better to have AV1 ticked?

Thank you so much, it's always a user error lol
