Any documentation on these?
I will document here.
Things to get used to with portable installs:
On a fresh install of MC there are no lav filters (used with ROHQ) and not all audio encoders are there either.
This only matters if you plan on using the portable install somewhere without internet.
To get the filters start a video with ROHQ enabled to get MC to download them. You will also have to do this when a new build includes a new version of lav filters.
To get audio encoders you can convert an audio file to each format you want to get MC to download them.
I believe around have of the available encoders are included in a fresh install of MC.
Issues with portable installs:
When backing up a library from a portable install, import/zone settings are not included. So when restoring a library from a portable install, all import/zone settings will be default.
But...If you restore a regular install’s library to a portable install, import setting are there. If you then backup this library it will contain import settings, but only those from the regular install. Changes done during portable use will not be there.
Portable installs won’t use Artist or Series art if located on the same drive as the portable install. An exception to this is if a regular that already points to the art is restored to a portable install. Note that only existing art will be used and any new art added won’t show up.
