o
Low resolutions: 480×270, 320×240, and 320×180, progressive, at half and
quarter frame rates (not available for 1080p inputs)
o
HD inputs can be scaled (and re-interlaced if necessary) to SD resolution,
anamorphic (not available for 1080p inputs)
o
720p inputs can be reduced to half frame rate (typically for Internet applications),
as follows:

1280×720p50 is converted to 1280×720p25

1280×720p59.94 is converted to 1280×720p29.97

1280×720p60 is converted to 1280×720p30
o
1080i, 720p and SD inputs can be converted to SD resolution, with progressive
frame rates (ideal for computer displays), as follows:

1080i59.94, 720p59.94, and 480i59.94 are converted to 720×480p29.97

1080i60 and 720p60 are converted to 720×480p30

1080i50 and 720p50 are converted to 720×576p25
The conversions from HD resolutions are done using anamorphic scaling.
o
1080i, 720p and SD

inputs can be scaled to 640×360, with progressive frame
rates, as follows:

1080i59.94 and 480i59.94 are converted to 640×360p29.97

720p59.94 is converted to 640×360p59.94

1080i50 and 576i50 are converted to 640×360p25

720p50 is converted to 640×360p50
o
HD 1080i inputs can be scaled to 1280×720p at the same incoming frame rate
(e.g., 1080i59.94 will be scaled to 720p29.94; 1080i50 will be scaled to 720p25)
o
HD 1080i inputs can be scaled to ¼ resolution (960×540), with the same
incoming frame rate
o
SD inputs can be horizontally cropped to 704 pixels or horizontally scaled to 640
pixels
o
SD inputs can be horizontally scaled to 640 or 528 pixels, and converted to
progressive frame rates (29.97p for NTSC inputs, 25p for PAL inputs)
If Video Input Settings is set to Auto Detected , the following options are offered in this
parameter:
o
Same as Input: the encoder will produce a signal that has the same resolution and
frame rate as the input (no scaling).
o
Scale 3/4 Horizontal: the encoder will scale down the image horizontally by 3/4.
The frame rate will not be changed.
o
Scale to 640×360p: the encoder will scale the input video to 640×360. The frame
rate will be the same as the input, but interlaced inputs will be de-interlaced (for
example, 1920×1080i60 will yield 640×360p30). This resolution is not available
for 1920×1080p inputs at any frame rates; the encoder will fall back to 3/4
horizontal scaling in this case.
o
Scale to 480×270p, Scale to 320×240p, Scale to 320×180p: the encoder will
scale the input video to the selected resolutions. Interlaced inputs will be de-
interlaced as described above. Progressive inputs will be encoded at half frame

By default, SD signals have a 4:3 aspect ratio, unless they are derived from an HD source with anamorphic scaling.
The 640×360 resolution is intended for 16:9 content. Scaling SD to 640×360 should only be done if the SD signal is
anamorphic to start with, otherwise the resulting encoded signal will have an incorrect aspect ratio.
