Yes — you can get HDMI video from a PC into a entity[“turn0product0”,“Blackmagic Video Assist 12G HDR 5”,1] / entity[“turn0product1”,“Blackmagic Video Assist 12G HDR 7”,0] / similar Video Assist recorder/monitor, but with important caveats:
- The Video Assist has HDMI (and some models SDI) video inputs and will accept a clean HDMI signal from any source — including a PC’s HDMI output — just like it would from a camera. It can monitor and record that incoming HDMI to ProRes or DNx formats to media cards/disks. That means you can feed HDMI from a PC into it and have it record/monitor the signal. citeturn0search16
- It doesn’t care whether the HDMI comes from a camera or a PC — it just sees a standard HDMI video feed.
- Blackmagic added “webcam/capture card” support in a firmware update (3.3+) where the Video Assist will show up to your computer over USB-C as a webcam/capture device if connected to the Video Assist’s USB port. That means the Video Assist can present whatever HDMI signal you’re feeding into it as a USB video input to your PC (e.g., in streaming software like OBS, Zoom, Teams, etc.). citeturn0search8turn0search11
- In this mode it basically acts like a capture card: HDMI signal in → USB-C to computer → usable video in apps.
- Resolution & frame rate limits: The webcam/capture support is generally limited to 1080p output over USB. It won’t act like a high-end dedicated capture interface feeding native 4K/60+ capture over USB. citeturn0search8
- Latency: There may be slight delays in the HDMI pass-through/processing, since it’s built as a recorder/monitor first, not a low-latency capture card. Some users have reported latency/driver quirks. citeturn0search1
- HDCP content: If your PC HDMI output has HDCP (for protected content), the Video Assist likely won’t accept/record it — just like most capture devices.
- Recording while in webcam mode: According to reports, you can still record internally while using it as a USB capture/webcam. citeturn0search11
- Yes, you can feed HDMI from a PC into a Blackmagic Video Assist and capture/record it.
- With the firmware update, it can function as a basic capture card over USB to a computer, roughly equivalent to a webcam input or simple HDMI capture device — but it’s not a full-featured, low-latency, high-resolution capture card like dedicated models (e.g., Blackmagic DeckLink/UltraStudio). citeturn0search8
If you need more traditional capture features (higher resolutions, lower latency, professional software integration), dedicated capture products like the entity[“turn0product5”,“Blackmagic Design Decklink Mini Recorder”,1] or entity[“turn0product12”,“Blackmagic Design UltraStudio HD Mini”,0] may be more appropriate.
