Magewell Pro Capture Mini HDMI
Give a compact or embedded PC an HDMI input, using only its Mini PCIe slot.
- ✓Mini PCIe card of just 30 × 51 mm (PCIe Gen2 x1), so you can add HDMI capture where a full-size card will not go
- ✓One HDMI 1.4a input (also DVI 1.0) with embedded audio, so the sound arrives with the picture
- ✓Input and capture up to 2048×2160 pixels; about 80 frames per second maximum at 1920×1080
- ✓Supplied 31 cm breakout cable ends in a full-size HDMI socket, which lets you mount the connector where your enclosure needs it
- ✓About 3.24 W maximum (high-performance firmware) or 2.7 W (low-power firmware), a good fit for small, power-limited systems
- ✓Windows, Linux and macOS; rated for continuous 24/7 operation

Building a kiosk, an industrial controller or a small-form-factor PC that has to take in an HDMI picture? When there is no room for a standard card, the Pro Capture Mini HDMI does the job from the Mini PCIe slot, the small internal card slot found in compact, industrial and embedded computers. It is a one-channel HDMI capture card that brings one HDMI source into the computer, small enough for the tightest enclosures.
What goes in
- One HDMI input. HDMI 1.4a, and DVI 1.0. Input resolution goes up to 2048×2160 pixels.
- Sound with the picture. Up to eight channels of HDMI embedded audio are available through Magewell’s SDK, so your application can capture audio without a separate input.
- Long HDMI cables. An adaptive equaliser supports cable lengths up to 30 m, which means the source can sit well away from the computer.
- Full-size HDMI through the supplied cable. The card carries a compact 20-pin JST SHD header, and the supplied 31 cm breakout cable ends in a full-size HDMI type A socket, so a standard HDMI lead plugs straight in.
What comes out
- To your software. Capture goes up to 2048×2160 pixels. Frame rates reach up to 144 frames per second depending on resolution, with about 80 frames per second as the maximum at 1920×1080. Standard 1080p at 60 frames per second is within that.
- Colour. 8, 10 and 12-bit sources in RGB 4:4:4, YCbCr 4:4:4 or YCbCr 4:2:2 are accepted, which suits computer outputs as well as cameras.
- Processing on the card. 10-bit video processing with cropping, scaling, de-interlacing, aspect ratio conversion, colour format conversion, frame rate conversion and OSD composition. The work is done on the card, which saves processor time on a small computer.
- More than one stream. The input supports unlimited capture streams, so two programs can take the same source at different sizes.
- Low delay. Latency is 64 video lines.
Why choose it
- HDMI capture for the smallest systems. The whole card is 30 × 51 mm, so it goes where a full-size card has no room.
- Hold the source to one format. The card can present its own customised EDID (the data that tells a source which resolutions to send), which lets you fix a source to the format your application expects.
- Match power to the build. Choose the high-performance firmware (about 3.24 W maximum) or the low-power firmware (about 2.7 W maximum). Power comes from the slot’s 3.3 V supply, so there is no extra power lead to route.
- Heat sink options. The card is available with three different heat sinks, each under its own SKU. Tell us about your enclosure and we will confirm which version suits it.
- Built to stay on. The card is rated for continuous operation, 24 hours a day, 7 days a week, in ambient temperatures from 0 to 60°C.
Setting it up
The card goes into a Mini PCIe slot and is fixed through its mounting hole. Then install Magewell’s driver. Software sees the card through the standard capture interfaces of the operating system: DirectShow on Windows, V4L2 on Linux and AVCaptureSession on macOS. That lets you use familiar programs including VLC, OBS, XSplit, vMix, VidBlaster and Wirecast, or your own application. Supported systems are Windows 10, 11 and Server 2016 to 2025, Linux with kernel 2.6.35 or later on x86, x64 and ARM, and Mac OS X 10.9 or later.
Where it sits in the range
This is the Mini PCIe card for HDMI. Its SDI counterpart is the Pro Capture Mini SDI. If your computer has a standard PCIe slot, see the Pro Capture HDMI and the rest of the Pro Capture range. For an M.2 slot, see Eco Capture.

Frequently Asked Questions
A Mini PCIe slot. The card is 30 × 51 mm, a different shape from the x1, x4 and x16 slots in a desktop PC. For a standard desktop slot, choose a full-size card from the Pro Capture range.
A full-size HDMI type A socket, on the end of the supplied 31 cm breakout cable, so an ordinary HDMI lead fits. The cable plugs into the 20-pin JST SHD header on the card. The connection is an input; there is no loop-through output.
2048×2160 pixels for input and capture. The maximum at 1920×1080 is about 80 frames per second, so 1080p at 60 frames per second is supported. For 3840×2160 sources, see the rest of the Pro Capture range.
About 3.24 W maximum with the high-performance firmware, or about 2.7 W maximum with the low-power firmware. It comes from the 3.3 V supply of the Mini PCIe slot, so the card needs no separate power connection.
Windows 10, 11 and Server 2016 to 2025, Linux (kernel 2.6.35 and above, on x86, x64 and ARM) and Mac OS X 10.9 or later, through DirectShow, V4L2 and AVCaptureSession. Software that uses those interfaces sees the card as a capture device.
The card comes with a choice of three heat sinks, each under its own SKU. Tell us about your enclosure and we will confirm which version suits it.
