Hi all,

Does someone know if chroma upscaling in madVR works in one or two steps, when presentation resolution is larger than luma plane resolution?

For example, I have a H264 video in 1280x720 pixels (4:2:0 color with progressive scan). So, when I play it on a 1080p display, does madVR:

1. First upscales chroma from 640x360 to luma plane resolution (1280x720) using selected chroma upscale algorithm
2. Combines 1280x720 luma with upscaled chroma
3. Upscales the resulting picture to 1080p using selected image upscale algo

OR

1. Directly upscales chroma from 640x360 to desired presentation resolution (1080p) using selected chroma upscale algo
2. Upscales luma from 1280x720 to 1080p using selected image upscale algo
3. Combines both images to presentation picture

Thanks!
