. Those settings will
immediately be applied to that Encoder. The loaded template settings can be fine
tuned, if desired, by adjusting the parameter values below.
Encoder Page
Each Encoder (1 and 2) has its own set of parameters that can be configured
independently.
Frame Rate
Selects the encode frame rate relative to the input frame rate.
Full -
The same frame rate as the incoming video will be encoded (factory
default).
Half -
Every other frame will be encoded.
Quarter -
Every fourth frame will be encoded.
Video Geometry
Selects whether the encoded video geometry is the same as the input or is set
manually.
Use Selected Input -
Apply the incoming video aspect ratio to the recording
(factory default).
Manual -
Allows adjustment of the size and pixel aspect ratio of the recording.
When Manual is selected, the Lock Aspect Ratio control (On, Off) and the
Width and Height sliders become active.
Lock Aspect Ratio
Selects whether the encoded video's pixel aspect ratio is the same as the input
video, or if the height and width can vary freely.
Off -
The Width and Height sliders operate independently (factory default).
On -
The Width and Height sliders are locked together. You can increase or
decrease the size of the recorded image, maintaining its pixel aspect ratio.
NOTE: Pixel aspect ratio adjustments change the size of an image by varying the
horizontal and vertical geometry of displayed pixels, which can change the
apparent horizontal or vertical resolution of the resulting image.
