Video Filters
601 Correction - Expand Color Space Filter
Description
The 601 Correction - Expand Color Space Filter expands video RGB values from
the ITU-R BT 601 recommended 16-235 range to the full 0-255 range. This filter is
useful when transcoding files between different systems that use different YUV-RGB
conversion methods. If you feel your result is missing brilliance the reason might be
that the codec of your source file or the target codec are not handling the conversion
between RGB and YCbCr properly. This filter can correct this.
Options
There are no options.
Notes
The Canopus DV and MPEG codecs use the ITU-R BT 601 recommended range of
16-235.

useful when transcoding files between different systems that use different YUV-RGB
conversion methods. If you your converted file looks too much enhanced in contrast
the reason might be that the codec of your source file or the target codec are not
handling the conversion between RGB and YCbCr properly. This filter can correct this.
Options
There are no options.
Notes
The Canopus DV and MPEG codecs use the ITU-R BT 601 recommended range of
16-235.
