H264 Video
Use this to encode the video with the H.264 codec. If the input video stream is already
encoded as H.264, choose this option if you need to change the stream characteristics,
such as setting a different streaming speed.
Tip:
Choose H.264 video to deliver video to Helix Server and to make it available
the widest range of clients. HLS clients, for example, require H.264.
Video Bit Rate
For
Video Bit Rate
, select a streaming bit rate for the video. The encoded stream’s total rate is
the sum of the video bit rate and the audio bit rate (see page 30). The bit rate you select should
be influenced by the streaming network, the client device, and video frame size, video frame
rate, and the desired media quality.

Video Format
The
Video Format
drop-down sets the frame size of the encoded video. If the frame size is in the
same aspect ratio (such as 4:3 or 16:9) as the input video, the video is scaled smaller or larger as
necessary to meet the target size. If the aspect ratio is different, the scaling mode (see page 27)
determines how the video is resized.
