a big difference between the source and target

[kingcrimsonster]

The bug is in the difference between the right preview window and the encoded file when the filter is 709 - 709 or it is off.

Load source Tablitsa.mpg.

If uncheck this filter - similar result
put the pipette on the green area in left and right window and measure RGB - 0, 162. 0



Encode this file, play it and put the pipette on the green area and measure RGB - 0, 193. 0



This is big difference between the right preview window and the encoded file.
If I want to manually adjust the color and I'll look at the right window the result will be incorrect.
