[Cin] The best strategy to render yuv (mpeg, limited range) from yuvj (jpeg, full range)?

So, my sources are in yuvj, and my target (youtube) is yuv. I want to find the best strategy to minimize color banding and maximize dynamic range available. My current settings for this are: - JPEG in "preferences"; - RGBA-float in "format" (color correction in YUV leads to a lot of color banding). The problem is: I couldn't render this RGBA-float into YUV. No matter what render settings I use, it renders in full range. Putting color_range=mpeg doesn't help, because it just flags the file to be in limited range, leading to increased contrast of image. So, I'm a little confused. What I am really supposed to do? Using ColorSpace filter is not convenient with filter like histogram, for example.
