Question / Help Color problems in video editor

[critical-z]

Hello. I recorded a test video with OBS with the AMF Encoder, using UV12 color format, 709 full range, and it looks like I want, however, opening the video in a video editor (I use AviUtl), the colors become very dark, and I simply do not want it looking like that.
Now, I can encode with x264 and set the color to be converted to 'PC tone', but that's not a real fix. I remember testing Sony Vegas years ago, and it had a similar problem, but there, you could go into preferences and check a box somewhere that used the video's original colors, but I can't find anything like that here.
What should I do?

Here's the original, correct colors.

Here's the darker, incorrect colors from AviUtl.

full range

Don't do this

Why? What's wrong with full range?

Players and other programs are expecting partial range and cause that color distortion.

Thanks. That's really interesting, and unfortunate.
As an aside, I tried opening the same video with VirtualDub FilterMod, and it displayed mostly correctly, although some colors still looked a bit darker.

Is there any way around this other than using partial range?

Nope.
