HDMI 1080p 30fps capture for creators

This USB 2.0 capture card accepts HDMI video up to 3840×2160@30Hz and delivers 1920×1080@30Hz to a computer or smartphone. It records both video and audio directly to disk without added drivers. Streamers, teachers and conference hosts can connect a DSLR, camcorder or action camera and start recording in OBS, VLC or Amcap on Windows, macOS or Android.

Thermals noise and power in daily use

The device draws a maximum of 0.4 A at 5 V DC from the USB port, so it runs without an external power supply and adds negligible heat to a laptop setup. No fan is present, making operation silent during long streaming or recording sessions. Low latency keeps game capture and meeting recording responsive even on modest hardware.

Compact aluminium shell and plug-and-play mounting

Measuring 2.5 × 1.1 × 0.5 in, the dongle fits beside other ports without blocking them and travels easily in a gear bag. HDMI input supports AWG26 cables up to 15 m, giving flexibility for camera placement in classrooms or studios. Compliance with UVC and UAC standards means it appears as a standard webcam and microphone to any supported OS, so no proprietary software is required for daily use.

Questions about this item

How do I install this capture card, and what step do people often get wrong?

Plug the HDMI source into the input, connect the USB 2.0 plug to the computer, and select the device in OBS or VLC; the step often missed is confirming the source outputs 1080p30 or lower, because the card downscales 3840×2160@30Hz input to 1920×1080@30Hz output.

What maintenance or replacement will this capture card need later?

No internal parts require servicing; only the HDMI cable may wear — the spec supports AWG26 cable up to 15 metres, so replace the cable if signal drop-outs appear.

What limit shows up first under sustained use?

The USB 2.0 bandwidth caps video at 1920×1080@30Hz YUV/JPEG, so extended sessions cannot exceed that resolution or frame rate regardless of the HDMI source.
