This is 480i S-Video through my Laserdisc player, using the Blackmagic Intensity Pro vs. the USB3HDCap.
The Blackmagic is set up so everything is default. I picked a pretty muddy/dark source on purpose- this laserdisc's source isn't the best. There was also not much if any perceptible difference between each capture boxes YUV to RGB conversion, so I captured these all RGB32.
Blackmagic Intensity - JP IRE - Default Settings
USB3HDCap - JP IRE - Default Settings
USB3HDCap - JP IRE - Recommended Settings
Blackmagic Intensity - US IRE - Default Settings
USB3HDCap - US IRE - Default Settings
USB3HDCap - US IRE - Recommended Settings
This is how everything looks. Using US IRE, things are the worst. Lots of lost detail even if the US IRE is much darker. I think with the recommended settings, it does look better, but maybe I need to pull back on the contrast a bit. This is a US laserdisc, so the color balance should be US IRE btw. I think capping at default in the JP IRE might be better, just because it can be color corrected to digital and is pretty close even if it's a little more contrasty.
Note that the 'Output Color Range' on the USB3HDCap would not stick. If I changed it to shrink or expand, it would always go back to 'bypass' in less than a second. Changing RGB24/RGB32 Color Range to Full Range and Limit Range did nothing- I'm guessing because this is S-Video?
It took me a bit to realize that Amarec's settings would overwrite the USB3HDCap's internal driver settings if you hit OK on their resolution menu after you change NTSC_M to NTSC_M J. Kind of a weird bug, but I guess it forces it to load the default IRE.
Aside, but are there thicker breakout cables you can buy for the USB3HDCap? I'm surprised these are so thin.
EDIT: After doing an update on the drivers, HDMI seems super spot on. Note the prior pics are from the reinstalled drivers. Dunno what was up with that before.

For whatever reason, the stupid Blackmagic Intensity will not pick up the HDMI signal properly. That thing has always been a problem, ugh.
