What's the difference between SD and HD?
What's the difference between SD and HD?
Updated over a week ago

The Alpha videos are free to download and save to your computer or to a flash drive. We recommend downloading the videos rather than streaming them. This will eliminate any internet, wifi or buffering issues.

You'll find the videos in the "Series Materials" section after you log in.

SD (standard definition) is suitable if you're watching the videos on a laptop (but not projecting it). It's a smaller file, so it will take up less room to store on your computer and it will download faster. The quality and colours on the screen are fairly good and the dimensions are smaller. Our SD videos are under 300 MB on average.

HD (high definition) dimensions are larger so this format will provide a better viewing experience and sound quality on a large screen or modern TV. It works best with a faster internet connection speed. The file has higher quality images and sharper colours. Our HD videos are 400-800 MB on average.
 Note: SD files are required for most iPads.
