Mercury Transmit via BlackMagic UltraStudio Monitor 3G Downscale is stretched.
1080 direct works fine, but we edit/master in UHD 3840x2160.
It appears Mercury Transmit is using the wrong pixel aspect ratio when downscaling a 3840x2160 sequence to 1920x1080 output. It is anchored to the right side of the frame and the left is stretched wider and off the edge of frame.
SIDE NOTE: After updating to Beta 24.2 in hopes of fixing the issue, the prefs (sprocket wheel) of the Black Magic Playback does not work. It did in the previous beta and does work in 24.1 Public.
