Mass import via an m3u playlist, if there all the same format eg mp4 you can mass encode as well but be careful not to crash your server. Depending on how good your server is you could mass import 2-300 films in 1 hit and encode it is trial and error how many you can encode at once as you server may become unresponsive for a while but if it has enough processing power and ram it will handle it, ive successfully imported 500 films then mass encoded approx 20 in 1 go.
