The second step analyzes the video file in more detail and offers import options:

-By default the video is imported using the original width/height. If it is a large video (e.g. full-HD) it will make sense to scale it down to lighten CPU and disk I/O required to play it. For editing sound-tracks, a small representation is usually sufficient. The default bitrate is set to use 0.7 bits per pixel. Some key values: the average DVD medium uses 5000kbit/sec. +Video Import Dialog
