Thank you obvious when you think about it 
I was wondering if a powered usb hub like this Elektron Overhub could work for video input and midi at the same time with Hypno? Would the previously posted limitations still apply?
You can try, but there isnāt enough bandwidth in the single USB 2.0 PHY available on the Compute Module, hubs result in glitchy video input with cutouts and there isnāt really anything we can do about this.

Iāve tried with a cheap USB hub unpowered. Connected a logitech webcam and LPD8 MIDI controller. Works like a charm.
Havenāt tried outputting video through the NDI at the same time though.
Very surprised by this as all my tests have resulted in bad performance, even if hubs work this will remain unsupported officially for power and UI reasons.
Please be careful not to power more than one device off of any hubs and do not charge any phones off of this port as this will likely damage your unit (and will not be covered by our warranty).
Hey Iāve been trying to find a way to use video input without a capture card for now.
How is everyone feeding webcams to hypno? Webcam usb to Female usb/small usb cable to front panel on hypno ? Is there a way to send video from laptop to hypno?
I have a zoom q2n. I know I could use q2n hdmi out to capture card to hypno but can I send the video from q2n to laptop and laptop to hypno via usb? Can you send hypno a laptops camera feed via usb?
For an external UVC webcam you just need a microUSB adapter, also known as a USB OTG cable. Iāve used my Logitech C920 with Hypno, no problems.
Iām not personally aware of any methods that let you send video out as UVC over USB from a laptop. Maybe this exists but itās not something weāve seen or tested. At any rate, if you have one of the HDMI capture devices then itās just a matter of connecting your laptopās HDMI output to the capture card (again, with the OTG cable), so thatās a pretty easy solution.

Thanks for reply.
Cool, I have 2 capture cards on the way. Looking forward to using the video input!
Appreciate the answer!

Just to clarify. There is no way to send video from laptop via usb to hypno with a usb to micro usb cable??
Weāre unaware of methods to send UVC video over a USB cable from a PC or Mac. If you find anything that does this, please let us know!

Iām trying to wrap my head around what I need/how to do the following:
play a video file from my Mac as input through the Hypno, and record the processed results back onto the Mac.
Can someone walk me through how that would work?
One approach is to use two video capture cards.
One taking an hdmi feed from your Mac. This is essentially set up as an external monitor and is outputting via usb to an OTG cable going into the front of the Hypno. Having a capture card with hdmi thru to another monitor would be super helpful here.
On the way back having hdmi out from the Hypno going into the second capture card feeding back into OBS on the Mac.
Instead of the first capture card you could also try using a suitable webcam pointed at the Macās screen, traditional video synth feedback style, again attached to the Hypno via OTG.
With either of these situations you might run into issues with your Mac not having enough or the right type of ports.

Hey noctambulance, welcome to the forum.
Syntheist has got it right in the above post, so long as your computer can support a secondary display and you have a couple capture devices, this should work fine. You signal chain would probably look like this
Input: computer HDMI output > USB2.0 HDMI capture device > USB OTG (microUSB) adapter > Hypno
Output: Hypno HDMI output > USB/TB HDMI capture device > computer
For the Hypno output going back into your computer you can use a second USB2.0 capture device, like the ones we recommend for video input, and get pretty decent results. However, youāll get better results with a higher quality capture device like Blackmagic Intensity Shuttle. You could also capture the composite output instead of HDMI, but the results will be lower fidelity.
To some degree your computers specs will determine how well this works. I havenāt had any specific trouble doing this myself with a ~4yo Thinkpad
Hey
Im getting a lot of noise through my speakers when using the front input of the hypno.The hypno is also being powered from the other usb port. The noise is present when the laptop is plugged in and not plugged in.i tried another cable with the hypno and same noise. It seems to be something between my soundcards usb and hypnos usb when they are both plugged into the laptop.
I have the dec 2020 hypno so maybe this is the problem but just wondering if anyone had the same issue and maybe a quick fix?
The recall fix wont/shouldnāt effect this.
This noise only happens when using video input? What does it sound like (high/low pitch)?
I havenāt tried hooking up this type of computer loop with audio tbh butā¦
Definitely power Hypno separately,
Try to isolate the audio interface if it is bus powered or the power of the front usb hdmi adapter.
Do you have any powered usb hubs to try on any of the ends?
Also be careful running HDMI/USB wires over audio cables, they contain high speed switching signals and will likely cause interference.
I am trying the following and it is not working so far:
Mac > USB HDMI capture device > HDMI cable > HDMI to micro USB adapter > Hypno front input
Iām also trying a Canon camera > HDMI cable > HDMI to micro USB adapter > Hypno input
any idea why these arenāt working?
I should note that this is an iMac with USB outputs
Is there any response from Hypno when you plug your capture device in?
no. Iām perplexed and thinking I may be using the wrong adapters. I think for the Mac video output, I need a usb C to HDMI adapter, as I donāt think it will stream video out of the USB A ports.
As for what I am connecting to the Hypno, Iām not having any luck with cameras with HDMI output. Hereās what I bought to plug into the Hyno:

Somehow the description for this device changed since I bought it - looks like it is probably not the correct device.
OK I just re-read your signal chain. It should be more like this:
(HDMI source) > HDMI cable > USB 2.0 HDMI capture device > USB OTG adapter > Hypno
You need one of these adapters to connect the USB2.0 capture device to your Hypno: https://www.amazon.com/UGREEN-Adapter-Samsung-Controller-Smartphone/dp/B00LN3LQKQ/
another day, another dead end. I bought an OTG adapter, but as soon as I plug the HDMI capture card it turns the video input into a bright yellow/green shape and none of the controls affect it. It prevents the Hypno from being able to cycle through all of the shapes - basically freezes the module. Hereās the OTG cable I purchased:
