Video Resolution
This pull-down menu sets the video resolution for the
outgoing stream. To make the stream the same resolution as
the input imply select “Follow Input”. Otherwise select an
outgoing resolution from the list.
NOTE:
Up-Scaling, (creating a stream larger than the
incoming resolution) is not recommended as it usually
results in severely reduced quality.
Frame Rate
This is the frame rate of the encoded video. ‘Full’ will result in the same frame rate as the incoming source. ‘1/2’ will be half the
incoming frame rate. ¼ will be one quarter the incoming frame rate.
Video Profile
Talon supports three h.264 encoding profiles; Baseline, Main and High. Profile selection should be based on the target audience
of the encoded video.
Baseline is the lowest level profile and is suitable for streaming to a broad spectrum of internet connected devices
including most older smart phones.
Main is the default setting. It is suitable for most web streaming including HD. It is also good for most modern smart
phones.
High is primarily used for broadcast, or for saving high-quality HD to file. It supports up to 1080p/60 video.
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 2 B Frames. When using Baseline, profile use 0
B Frames. For most situations, a setting of 1 frame is best.
DeInterlacing
Most streaming 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.
