Video Filter tab
The Video Filter tab lets you apply filters to your video to help improve image quality of
your source files before they are converted. These filters can be previewed in this tab, but
are applied when the video is being converted to its new format.
Video filters
601 Correction -
Expand Color Space This video filter expands the RGB range of the video from 16-235 to
0-255. Use this filter to create output for a system that uses the full
0-255 range from input that uses 16-235.

16-235. Use this filter when create output for a system that uses the
16-235 range from input that uses the full 0-255 range.
601 to 709 Color
Correction This video filter is used to convert video in the SD (601) colorspace
to the HD (709) colorspace. Broadcast HD video uses YCbCr colors
following Rec. ITU-R BT 709-5 where as broadcast SD video follows
ITU-R BT 601.
709 to 601 Color
Correction This video filter is used to convert video in the HD(709) colorspace
to SD(601) colorspace.
Adaptive De-interlace This video filter combines the fields of an interlaced video source’s
fields back into whole frames using special processing to preserve
full resolution while ensuring smooth motion.
Bitmap Keying Superimpose a bitmap logo or graphic on the video. This is often
used to watermark video so it can be personalized.
Black/White Correction This filter lets you adjust and control the levels of black and white
pixels in your video. By adjusting the sliders, you can specify at
which point a pixel will become black and/or white. The higher the
setting, the more nearly black pixels will be converted to true black
and vice versa. This works best if you are encoding video for the
Web and need to adjust the black and/or white levels of broadcast
video so that they are truly black or white. It’s also useful for making
white titles on a black background more legible when viewing on a
computer monitor.
Blur This filter blurs the video in a rectangular pattern.
Broad cast Color Safe Some colors that can be displayed on a computer cannot be
displayed on television or video output. This filter restricts the
colors in the source to only colors that are safe for television and
video broadcast.
Circular Blur This filter blurs the video in a circular pattern.
Color Correction This filter allows you to adjust the brightness, contrast, hue and
saturation of your video image.
