Camcorder detection not working with latest Monterey 12.3 update

Can someone confirm if their camcorder detection is working with QuickTime iMovie and FCP import from camera window with latest Monterey update It has stopped working for me I have sent Apple feedback but it would be great to get more confirmation from real world users Thanks in advance

Yes, I found your post and replying as I have this same problem!

Thanks for the confirmation Cheers I can’t believe they broke it

I noticed this about a month ago and posted about it in Apple Communities here: discussions.apple.com/thread/253757258 . Several people have confirmed this is broken. I've tried contacting Apple in different ways (support & feedback) to no avail. Does anyone have a clue if this will be fixed?

My issn’t working also. I am using nnow my old imac with high sierra to capture tapes

Hi Nice.. but not nice to hear you have a identical problem to me... I bought a M1 mac and the apple adapters to go from firewire  to usb/c thunderbolt on a iMac M1 
Thought I was making a smart move with replacing my iMac with a M1 soon faded after the monterey update and now i can't see my ADVC 300/ sony tape deck with fire wire out and also my link on my camera all have never been detected despite 2 days re formatting my Mi and re installing Monterey and starting again....2 days of my life wasted.... so now I'm using my old intel based iMac and big sir  its the only thing i have that works for me. 
And it seems i can't undo the last Monterey update so feeling ripped off now....

I have spent a week on this topic and to be honest this thread is the best i have found  i have the same problem but apple  just say check or replace the leads....Do they have no idea what has happened so what's the answer ??? would  back installing big sure and turn off the auto ud date facility  work ???? I'm getting tired of this and feel apple are  just out to rip us all off....

Tape capture does not work with the current OS. Absolutely switch off auto updates in Software Updates and in the App Store. If you can install Big Sur on an external SSD, that would be the best solution at the moment. 

Thank you for putting me out of my misery is there any analogue capture units that would work with Monterey 12.3.1 I have a feeling you going to say no...
Thanks for your help its a life line as I've tried everything to no avail.

Same here... sadly your not alone and no news of a update or a fix, not even a work around.
A lot of us 'still' use old capture i-link or fire wire especially as to date I have not found a analogue capture device to thunderbolt 3

No device will work. The problem is in the OS.

I don't no why my last post did not get posted her bus this is what I found on Apple website about supported Camara's (sorry in Dutch)

support.apple.com/nl-nl/HT204203

No tape based Camara's anymore!

Bus in FCP Manual This:

support.apple.com/nl-nl/guide/final-cut-pro/verd0e78a7e/mac

So it is conflicting (I hope this the right word)

I did a search on Apple's support doc number and the English version is here:
support.apple.com/en-gb/HT204203

This is mainly about file formats that are directly playable by FCP.

However, at the bottom it does say about Firewire and DV recorders being usable. I checked in System Information on Monterey 12.3.1 and the Firewire extensions are still there. I have only just updated to Monterey, but I will have a try with this when I get a chance.

I have previously successfully transferred tapes from a Sony A1E HDV camera in Big Sur, with a TB3 to TB2 adapter, TB2 to FW adapter and even then, a FW800 to FW400 adapter and it worked.

Meanwhile, Firewire from cameras has always been a bit flaky and I have found that some success of making the Mac and FCP see the FW was to have it all connected, even have a tape running so that there's a signal there, and then reboot. Firewire, like USB, works on discovery, in other words you should be able to plug it in and the Mac sees it. Unlike a Firewire disk drive, however, which tries to 'talk' to the Mac as soon as it's powered, I don't think cameras 'talk' to the Mac very well and the Mac doesn't see a FW device if there's no real signal there.

Last, but not least, make sure you're plugged into a Thunderbolt and not just a USB-C port, and maybe no docks in the way.

Just my 10p.

The DV and HDV devices are recognized by the OS in System Information, but the system does not work with them. The problem is specifically in the macOS 12.3.1 update.

Thank you is the a way of going back to before the 12.3.1 update.
Ive been trying to create a second volume and install Big Sur now thinking about a dual boot partition on my ever shrinking hard drive space.

How do I install Big Sure on an external hard drive it dose sound a good solution if i only knew how to do this...

Thank you all help and info I'm sure is a huge help to us all suffering this hassle from  Apple

Download Big Sur from the App Store. Then you need to create a bootable jump drive with the installer. Search the internet on how to do this with Terminal. Boot onto the jump drive and run the installer onto an external SSD.  

Hi  thanks for your input but like you i had no problems until the last 12.3.1 update i too found it showed up under system info and  even bought a new TB2 to TB3 usb/c connector thinking as it all still worked on my 21.5 Image using a intel processor and had no problems, so i as a last fingers crossed  effort ( but now I know Better what's going on)  I assumed just maybe I had a faulty adaptor .... But alas   no.... all i have now is a spare TB2 to TB3 adaptor....

Ah im almost there im now trying to i think make a bootable USB drive using terminal... but like most things I try to do is  only seems to work part way then the problems start.. im afraid I don't fully understand what's going on so I can only follow the instructions word for word....
