Overview

The Blackmagic Design Video Assist 5" 12G HDR is a professional on-camera monitor and recorder built for filmmakers and video professionals who need accurate, high-brightness monitoring in any environment. Its 2500-nit HDR touchscreen panel delivers true-to-life color and contrast, making it a reliable reference even under harsh outdoor lighting. With both 12G-SDI (via Micro BNC) and HDMI 2.0a connectivity, it pairs seamlessly with cinema cameras, DSLRs, and mirrorless systems alike, supporting resolutions up to 2160p60 over SDI.

Beyond monitoring, the Video Assist doubles as a capable recorder, capturing footage to standard SD cards in professional codecs that often surpass in-camera recording quality. The unit includes a comprehensive suite of production tools including waveform monitors, vectorscopes, histograms, focus peaking, zebra exposure, false color, and 3D LUT support. Its 16-channel embedded SDI audio and 8-channel HDMI audio handling ensures complete audio monitoring. The compact, durable build keeps your rig lightweight while delivering the kind of professional monitoring tools that were previously reserved for much larger and more expensive units.
