Hey...

I've had my 224MC for about three years now and have had great success with it. Just recently I noted that while recording videos there is a significant 'flicker' as if a cable is loose. Well as I am very wise I changed out my USB to C adaptor for my laptop. No change. Below is an image of a the SER from PIPP. 

What is the story?

My guess is usb overflow.  Check your usb traffic setting.  Which software did you use to capture, and what were your settings?  If you used FireCap, it's helpful to post your settings file.  Did anything change in your physical usb configuration?

I am using CPWI and SharpCap; no change in my settings. USB is 3.0. I see I have high speed mode on and turbo at 100. I just turned High speed mode off and turbo down to 80. It seems to have helped as I image my ceiling,lol.

I just now turned OFF 'Planet Stabilization'. The flickering stopped. Hmm.

The camera was not getting hot but that could’ve been a cause. I discovered. It was USB traffic. I turned high speed off and turbo off,as well as planet stabilization. All well. 
I was intially convinced it was a bad cable but it was not. I am even using a USB booster.

Just wondering, could it be a wobble in the scope?

Ranger 4, definitely no but something that could have been. Really stable set up. I'm pretty sure it was USB traffic.
