 +Specifying a property with an empty value, which is often done for EncodingProfile.IsMaster, will match if this property does not exist at all on a ticket. So for EncodingProfile.IsMaster, specifying an empty filter will match on recording tickets which never have this property.

-Similar to variant 2, but the release encoder (minion) only mounts the /video/fuse/$room/ from each recording cube. The encoded and tmp files life on one minion, the secondary minions mount /video/encoded and /video/tmp from the primary minion. [Reason: It is not guaranteed that the minion which encoded a talk also does the postprocessing (upload) step.]+Similar to variant 2, but extended to work with multiple rooms. Instead of using rsync, recorded snippets remain on the encoding cubes and ''/video/fuse/$event/$room'' are exposed via samba to the minions, while the encoded and tmp files live on one "central" minion; all other minions mount ''/video/encoded'' and ''/video/tmp'' from the primary minion [reasoning: the tracker cannot guarantee that the machine which encoded a talk also does the postprocessing (upload) step, so all minions have to see the same files].
  
-You have to set the room filters only for the recording cubes, the minions can process talks independently.+Tracker filters have to be set only for the recording cubes, minions do not require any filters (but on smaller events without many minions, a ''EncodingProfile.IsMaster=yes'' filter can be a good idea, so sub formats won't crowd out the queues — they can always be encoded off-site later).
  
-  * On recording cubes:   start systemd units for steps A ''crs-recording-scheduler'', B ''crs-mount4cut'', and C ''crs-cut-postprocessor''         +On recording cubes: start the followin systemd units:

 + * ''crs-mount4cut'' 
 + * ''crs-cut-postprocessor''
  
 +On all minions, including the one acting as storage, do
  
 +  mkdir -p /video/fuse/$event/{$room1, $room2, ..}
 +  mount.cifs -o uid=voc,password= {//$encoder1.lan.c3voc.de,}/video/fuse/$event/$room1
 +  mount.cifs -o uid=voc,password= {//$encoder2.lan.c3voc.de,}/video/fuse/$event/$room2
 +  ...
  
-==== New example with systemd units and case 1 and 5:+On all minions except the one acting as storage, also mount: 
 + 
 +  mount.cifs -o uid=voc,password= //$storage.lan.c3voc.de/encoded /video/encoded
