Turning my Canon HF G70 into one of the most expensive webcams I will probably ever use
In my Dead Space stream, I started using my Canon HF G70 as a webcam.
Stream example:
And yes, this is one of those setups that is both stupid and practical at the same time.
I bought the Canon HF G70 about two years ago, around 2024, and I have barely used it. I honestly kind of regret buying it. Not because it is a useless camera, but because I never really liked the recording quality enough for the kind of videos I wanted to make with it.
So instead of letting an expensive camera sit there doing nothing, I decided to use it for something.
A webcam.
A very, very expensive webcam.
I paid around 6,666 DKK for it when I bought it, which is roughly €891.82 / $1,034.32. Today I have seen it around 7,490 DKK, which is roughly €1,002.06 / $1,162.18.
So yes. If we are going to be dramatic about it, this is probably one of the most expensive webcams a normal person can accidentally end up using.
But the annoying part is that, as a webcam, it actually makes sense.
The video quality is much better than a normal cheap webcam. It is a real camcorder, not a tiny plastic webcam pretending to be a camera. It has proper optics, better control, better image handling, and it simply looks more serious than a basic webcam.
One big reason the Canon HF G70 still makes sense for streaming is the autofocus.
It has face detection / face tracking autofocus, so when I am sitting in front of it, it should detect my face and keep focus on me instead of drifting to the background. That matters when gaming, because I am not sitting like a statue. I move, lean back, look at the screen, react to the game, and sometimes probably look like the Ishimura itself is draining my soul.
A normal cheap webcam can easily look soft, flat, noisy, or just generally bad. With the G70, the picture side is much more solid. It can keep my face in focus, and that means the camera can actually behave like a high-end webcam.
So the video side is not really the problem.
The problem is sound.
The Canon can send video over USB-C as a webcam/UVC device, and that part works. But in my setup, USB-C only gives me the video. I do not get usable microphone sound from the camera through USB.
So the picture works.
The sound does not.
Because of course it cannot just be simple.
This means I had to build a workaround, because I still wanted to use the camera’s built-in microphone somehow. The camera has a headphone output, so my test setup is:
Canon HF G70 built-in microphone
→ camera headphone output
→ 3.5 mm jack male-to-male cable
→ Yamaha AG06/AG03 mixer input
→ Yamaha mixer sends audio over USB
→ PC / OBS / stream
So instead of the camera sending audio through USB-C directly, I am taking the camera’s audio from the headphone jack and routing it into the Yamaha mixer. Then the mixer acts as the USB audio interface and sends the signal to the PC.
It is very “Linux gamer with too much old hardware and not enough sleep,” but technically it should work.
The video path is simple:
Canon HF G70
→ USB-C
→ PC
The audio path is the cursed one:
Canon HF G70 built-in mic
→ headphone out
→ 3.5 mm jack cable
→ Yamaha AG06/AG03
→ USB
→ PC
The Yamaha mixer is made for streaming and audio-interface work, so that part makes sense. It can take audio sources, mix them, and send them to the PC over USB. So the Canon handles the video, and the Yamaha handles the audio.
The main downside is obvious: the built-in camera mic is still a built-in camera mic.
It is not close to my mouth. It is about an arm’s length away from my face. So the sound is going to have some room tone. It will pick up more of the room, keyboard, chair, game audio leakage, and general background space than a real close microphone would.
That is not really the camera’s fault. That is just physics. The farther the microphone is from your mouth, the more room you hear. A mic close to your face will almost always sound better for voice than a mic sitting on a camera across the desk.
So yes, the sound will probably be more roomy.
But if it works, it is still better than nothing.
The real test will not be whether it works in a silent local recording. The real test is whether it still sounds usable when game audio is under it, especially in a game like Dead Space, where the sound design is full of vents, metal, monsters, whispers, machinery, alarms, and general psychological damage.
That is where bad microphone audio can drown fast.
I did some basic testing, and so far it seems usable. The question is how well it holds up during an actual stream when the game audio is running and I am talking over it.
If the sound is acceptable, I can live with it for now.
Because the other option is buying a new microphone, and I am not really in the mood to spend 500–800 DKK on that right now. That is around €66.89–€107.03 / $77.58–$124.13.
A small camera-mounted or clip-on mic could be around 149 DKK, roughly €19.93 / $23.12, and that might already improve the sound if placed better. A more serious mic around 700 DKK, roughly €93.65 / $108.61, would probably sound better, especially if it is more directional and has some kind of windscreen or filter.
But even then, distance still matters.
If the mic stays on the camera, it is still an arm’s length away. A better mic pointed at me would help, but it will not magically behave like a proper close microphone near my mouth.
So this is where I am right now:
I have an expensive Canon HF G70 that I regret buying for normal recording.
I do not like letting expensive hardware sit unused.
As a webcam, the video side actually makes sense.
It has proper camcorder image quality, face tracking / face detection autofocus, and should keep my face in focus while I stream.
USB-C gives me video, but not proper mic audio in my setup.
The workaround is routing the camera’s headphone output into the Yamaha mixer.
The Yamaha sends the audio to the PC over USB.
The audio may sound roomy, but it may be good enough for now.
And honestly, that is very much my kind of setup.
Not clean.
Not perfect.
Not “professional studio polished.”
Just a gamer trying to make the hardware he already owns actually do something useful.
If it was not around 4 in the morning and I did not have to be up again in a few hours, I probably would have tested it properly right now with local recordings, game sound, voice testing, OBS levels, and all the usual “just one more setting” nonsense.
But I also know myself.
That is exactly how you go from “I will just test this for 10 minutes” to “why is the sun coming up and why am I still adjusting audio filters?”
So the real test will probably be in the next episode.
If it works, then my Canon HF G70 becomes my absurdly expensive webcam.
If it does not, then I am back in the endless technical swamp of Linux streaming, audio routing, camera workarounds, mixer settings, and asking myself why I keep doing this to my own brain.
But for now, the plan is simple:
Use the Canon for video.
Use the face tracking so my face stays in focus.
Use the Yamaha mixer for audio.
Accept that the built-in mic may sound a little roomy.
Avoid buying another mic unless I really have to.
And keep streaming.
Because at the end of the day, the setup does not have to be perfect.
It just has to work well enough that I can play games, talk, and not sound like I am broadcasting from the bottom of the USG Ishimura’s ventilation system.
