x264vfw issues, some CLI options and log doesn't work

[mzso]

Hi!

I've been trying to encode videos with x264vfw (is this official?), but I got some problems.
I added these (that I used a while ago with the CLI encoder) to the command line:

 --input-range PC --output-csp i444 --range PC --colormatrix bt709 --colorprim bt709 --transfer bt709

But it doesn't work as expected. input/output range options result encoding at all.
If I take them out I get a green video. After I remove the colormatrix option I get proper video. I wonder why these don't work.

The log option seems useless. I get a flickering blank window, which disappears after encoding is finished. Weird...
