GOP Size
GOP size refers to the distance between i-frames in a stream or file. Live streaming generally uses
shorter GOP sizes than saving to file. For live streaming a setting of 2 x (frame rate) is a good starting
point. If your encoded stream will be 30 fps, set the GOP to 60 frames. Some server based transcoders
prefer GOP up to 10 seconds.
Number of B Frames
B Frames provide encoding information to the i-frame. Talon supports from 0 to 3 B Frames. When using
Baseline profile use 0 B Frames. For most situations a setting of 1 frame is best.
DeInterlacing
Most steaming video is destined for delivery to a computer or smartphone screen. Such screens can only
display progressive video. Most analog video and 1080i HD video are delivered as Interlaced video.
These sources must be de-interlaced before they can be encoded for progressive delivery. Talon
supports three settings.
 OFF: No DeInterlacing will be applied.
 DEINTERLACE: Standard DeInterlacing will be used.
 DEINTERLACE HQ: This level is suitable for some save to file HD video.
NOTE: When encoding multiple streams, the same DEINTERLACE method is used across all streams. Be
certain to select a method that is applicable for all streams. Once a stream has started the DEINTERLACE
method cannot be changed on subsequent streams until all streams are stopped.
Maximum Delay
This setting adjusts the amount of internal buffer the encoder is allowed to use. Larger buffer gives the
encoder more time to produce more accurate video. The default of 2000 is generally adequate for most
live streaming. A setting of 0 will result in blocky video. A setting above 5000 does not usually provide a
significant improvement.
Audio Enable
When set to “True” audio inputs are made available for embedding in the video stream. Set this to
“False” if this input will not be using audio.
IMPORTANT NOTE: In 2x2 LC mode, only one input can supply audio at a time. Make certain the audio is
enabled on the input delivering audio and disabled on the rest or the video may not start correctly.
