Seagull Video Player Carbon (MacOS X) 2.5

Seagull Video Player easily creates video playlists. That means you can select a group of videos, and Seagull Video Player will play them all, one after another.

You can have a virtually unlimited number of playlists, each with as many videos as you like. They can be moved up or down in the playlist or shuffled so they play in random order. You can sort your playlists by video property in ascending or descending order.
Version 2.5 features: view videos in playlists as thumbnails; view multiple playlists at once using separate windows; and other enhancements.
