<p>I have a camera that can only provide a HDMI output. It does not have in-built recording capabilities as it is basically meant to be displayed directly on a screen.  </p>

<p><strong>My Goal?</strong>  </p>

<p><em>I want to record that feed.</em> </p>

<p><strong>Components I have:</strong></p>

<ul>
<li>A Windows PC</li>
<li>HDMI to USB cable.</li>
</ul>

<p>I asked around and it turns out that I would need a frame grabber to read the HDMI video feed, convert to a language the computer understands and send the converted feed via USB to the computer. That's pretty neat.</p>

<p><strong>But My Problem</strong></p>

<p>I don't have funds right now to get any new device. So how do I make the computer understand the raw HDMI feed via USB without using a separate device?</p>

<p>Is there a software/driver which can do that? Some sort of a signal analyser? What options do I have?</p>

# How to record HDMI video with USB?

(Asked by: username_0 on 2017-01-19)

I have a camera that can only provide a HDMI output. It does not have in-built recording capabilities as it is basically meant to be displayed directly on a screen.

**My Goal?**

*I want to record that feed.*

**Components I have:**

* A Windows PC
* HDMI to USB cable.

I asked around and it turns out that I would need a frame grabber to read the HDMI video feed, convert to a language the computer understands and send the converted feed via USB to the computer. That's pretty neat.
