This part alone, with every other slot assumed generous and a platform that allows the tier. Your build's real verdict is the lowest ceiling across all its slots, which is what the configurator computes. Conservative planning budgets, not measurements: methodology.
Our take on the Blackmagic UltraStudio Recorder 3G
The Blackmagic UltraStudio Recorder 3G is a small capture box that takes HDMI or 3G-SDI into a computer over Thunderbolt or USB4.
The tracked price is $175, near the bottom of a $175 to $179 range across three points from August 26 to October 1, 2026, so there is no gain in waiting. The listing describes 10-bit broadcast-quality video and says it works with DaVinci Resolve and live streaming software. It is a good match if your camera outputs SDI or if you want a capture path that does not depend on a USB 3 port. It is a box for a PC with Thunderbolt or USB4, so check your ports. The description calls it the Express Recorder 3G. No retailer ratings are listed.
