First, you need to upload a video to your DaCast account.
Second, you need to select that video and then go to the tab. From there, you can then see media information and any multi-bitrates that might be loaded:
Under this tab, you’ll see a list of resolutions. The top resolution will be marked as “Original File.” This will be the resolution and bitrate of the video file you just uploaded. If you are uploading a file that is not compatible (a red or yellow “Original file name”), you can also encode a compatible version at the same resolution to replace the original for your viewers.
Resolutions below the original will appear with an icon (to add these to the video profile). The encoding process can take some time, depending on file size. You can track progress with the “Waiting” progress bar before , to confirm that the file is encoding correctly. Note that you can leave the page while the progress bar is going–this won’t delay the encoding process at all.
When the encoding has finished, the files automatically appear in your profile for viewers to access.
NOTE: If you later decide to remove a bitrate, simply click the and then DELETE.
How Multi-Bitrates Work for the Viewer
After setup, viewers will see an HD symbol next to the full screen icon in the lower right corner.
Clicking this HD symbol brings up a series of options:
Auto is default, selecting a quality based on their connection speed.
Other bitrates can include 1080p, 720p, 480p, etc. Each option refers to a different quality–the higher the resolution, the higher-quality the video for your viewer. See below for a screenshot of how a video quality changes between these resolutions.
Advanced Settings: Adding More Bitrates
By default, 1080p, 720p, 576p, 480p and 240p are accessible for encoding through your DaCast account. You cannot encode to a higher resolution than the master file.
However, if you want to encode to different resolutions, you have the option to change the format (e.g., not use MP4, H.264 video and AAC audio) and create new bitrate templates.
To do this, click PREFERENCES at the top of the screen, and then VIDEO PREFERENCES. From here, you will see VOD Encoding Templates at the bottom of this page. You can click to add a custom profile, for example, adding a 800p resolution option.
Please note that adding Encoding Templates is an advanced feature. Most broadcasters (and viewers) should be fine with the default settings, without needing to add additional resolution options. However, these features are available to provide even greater control over your encoding for those who want it.
