C:\Users\Selur\Desktop\test2.vpy:54: DeprecationWarning: register_format() is deprecated. Use "query_video_format" instead.
gray_format = core.register_format(vs.GRAY, clip.format.sample_type, clip.format.bits_per_sample, 0, 0)

which brings me to http://www.vapoursynth.com/doc/pythonreference.html#Core.register_format but sadly using 'query_video_format' in the search there doesn't get me any results.
-> How to use query_video_format ? to replace the above line to get rid of the warning=
Error on frame 0 request:
Resize error: Resize error 3074: no path between colorspaces (2/2/2 => 5/2/2). May need to specify additional colorspace parameters.
This code did work before,..


Would be nice if someone cloud help solve these two problems.

Okay, seems like the output of the MaskedMege isn't RGB24 like I suspected but the same as the clip, so I don't need the last conversion.
So the only question remaining is how can I use query_video_format to avoid the deprecated warning?

gray_format = core.query_video_format(vs.GRAY, clip.format.sample_type, clip.format.bits_per_sample, 0, 0)
