In this article, we will show you how to create multiple renditions for your on-demand videos on Dacast via multi-bitrate encoding.

By default, all videos uploaded to Dacast will be encoded using our “Standard” recipe. 

This recipe includes the following renditions:

  • High Definition (HD)
  • Standard Definition (SD)
  • Ultra-Low Definition (ULD)
  • Magic

If you are not familiar, magic encodes the video using the bitrate of the source file, giving you the highest quality possible.

You may create new recipes to use for different videos or a new recipe to use by default. To do sp, select “Settings” and then click “Encoding” on the left side of the dashboard.:

You can now name your recipe for easy reference. If you would like this recipe to be the default recipe for all your content, select “Set as Default Recipe.” You also have the option to choose a watermark. 

At this point, you’re able to select which renditions of the videos will be served to your customers. Please note, that if the bitrate is higher than the rendition you select, that rendition will be skipped. It is always a good idea to select a smaller rendition for users that may not have the best internet connection.

If you do not want to encode your videos, you may create a new recipe with only the DNE (Do Not Encode) option selected:

Once you’ve configured these settings, you are now ready to upload a video to your Dacast account. You can do this by selecting “+” then “Video” from the dashboard:

You can now drag and drop the file into the window or select “Browse Files” on your computer. Once you select the video, it will automatically start the upload process. 

When the upload process is complete, the system will start encoding your videos according to your specified recipe. They will be available in the “Videos” section when completed. 

How Multi-Bitrate Streaming Works for the Viewer

After setup, viewers will see an “HD” symbol in the settings icon in the lower right corner.

Clicking the “HD” symbol brings up a series of options. Auto is the default, which automatically selects a quality based on each viewer’s connection speed.

Other bitrates will include a list of the renditions available. Each option refers to a different quality. Please remember that the higher the resolution, the higher-quality the on demand videos will be for your viewer.
