Netflix Canada Creates 3 Streaming Rates

To cope with new user caps in the Canadian market, Netflix has created three different image quality levels for users of the streaming service. The "Good" setting is the default setting and provides good picture quality and lowest data use per hour (about 0.3 GBytes perc hour).

The "Better" setting consumes about 0.7 GBytes per hour. The "Best" setting picture quality consumes about 1.0 GByte an hour, or up to 2.3 GBytes per hour when streaming HD content.

The "Good" setting limits video and audio to 625 kbps and 64 kbps, respectively. The "Better" setting limits video and audio to a maximum of 1300 kbps and 192 kpbs, respectively.

The "Best" setting will use any of the video and audio rates available. The highest quality files are 4800 kbps (for 1080p HD video) and 384 kbps audio (for 5.1 audio).
