Stretch mode

To enable stretch mode, click

Stretch Mode

on the

Effect Settings

tab. When stretch

mode is enabled, the display shows the input frame stretched to fit into the output frame
determined by the encoder settings on the

Encode Settings

tab. Stretch mode can be

applied when the input frame is smaller or larger than the output frame so that the input
size is forced to the output size.

The image description that is displayed for this option includes:

z

Image Size — The horizontal and vertical pixel format of the source frame

z

Target Size — The desired pixel aspect of the output frame

z

Position — 0,0 (default position). No adjustment is possible in this mode.

Letterbox mode

To enable letterbox mode, click

Letterbox Mode

on the

Effect Settings

tab. The video

frame that is displayed is centered horizontally and vertically with a red border in letterbox
format.

NOTES:

Letterbox mode functions only if the input frame is smaller than the output

frame determined by the encoder settings on the

Encode Settings

tab.

Depending on the resolution of the source files and the target resolution,
this mode may also result in pillarbox images (black bars on the sides) or
windowbox images (black border around the image).

The image description that is displayed for this option includes:

z

Image Size — The horizontal and vertical pixel format of the source frame

z

Target Size — The desired pixel aspect of the output frame as defined on the

Encode

Settings

tab

z

Position — It is dependent upon the sizes of the input and output frames. By default,
the source image is centered within the output image size.
