Transcoding Preset Default Settings

By default, four transcoding presets have been defined for VBrick Rev when your system is installed. These four presets have been carefully tested and authenticated and are the recommended settings to use to transcode a stored file from one video encoding format to another. They are seen in Table 1 below.

For example, when adding a stored .mp4 video, the file can automatically be transcoded to H.264 or HLS format. The presets defined below are used to configure the bitrate, frame rate, aspect ratio, and so forth of the transcoded output.

Admins can also specify which user actions or “rules” will prompt transcoding to occur such as when users add or record a video. If set, when a user performs the action specified, a list of the transcoding presets selected will appear for the user to select.

Preset Name	Description	Encoding Output
Standard Definition	Distribution Method: Supports a broad range of Internet connections. Target Displays: Works best for embedding on Web pages.	H.264
High Definition 720p	Distribution Method: Best for higher Internet Speeds or Corporate Intranet. Target Displays: Tablets, TVs, and full screen PC viewing.	H.264
High Definition 1080p	Distribution Method: Corporate Intranet. Also useful for local archival and playback. Target Displays: TV, full screen PCs.	H.264
Adaptive Streaming	Distribution Method: WiFi or 4G+ Delivery Method: iOS and Android smartphones and tablets.	HLS

Each preset has additional attributes such as an average bit rate versus a peak bitrate setting defined for video and audio.

Preset Name	Video Bitrate	Avg. Bitrate	Peak Bitrate	Frame Width	Frame Height	Audio Codec	Audio Bitrate	Audio Sample Rate
Standard Definition		800	1100	640		AAC-LC	96	48
High Definition 720p		2100	3000	1280		AAC-LC	128	48
High Definition 1080p		4000	5400	1920		AAC-LC	160	48
Adaptive Streaming	2962/1800/1200/688/420/230			1280/856/640/640/512/476		AAC-LC	128	48

Tip: Each transcoded instance of the video is presented to the user on the Video Settings page. Further, the user may choose which instance to play in the Video Player. See: View all Transcoded Video Instances.

Keep in mind, the user will be presented with the following playback options to select when more than one instance of the video is available:

●Auto where auto = HLS or the lowest quality stream available.

●Each available video quality where the transcoding output type = H.264.
