Hi8 Tape to Laptop out of sync

Let's back to track.
@koala already said that there were no errors in the log, so no sense to look at performance.

Do you remember the audio in device named "Microphone (USB2.0 MIC)" that OBS tried to use as default device? This is sound form the "AV TO USB2.0" camera. Yeah, this cheap capture card is emulation of USB camera (named "AV TO USB2.0") with the mic (named "USB2.0 MIC"). The first OBS log had info that sampling rate for this mic in "shared mode" was set at 96000Hz (likely mono). I thought that it worth to try to set it to 44100Hz as everything else in your PC and then cross your fingers...

I wasn't familiar with this capture device. So, I looked online. There are few videos from the manufacturer how to use this capture device (or likely similar device with the vid_534d&pid_0021), I found them only on the market page of the product. This is "MS210x Video Grabber [EasierCAP]" or similar MacroSilicon family devices. This devices always outputs progressive frames (deinterlacing not needed). Max is 720x480@30fps or 720x576@25fps with MJPEG format. Audio can be mono.

It can be a bug in OBS that it shows only 44100Hz for the Video Capture Device source in the log. Worth a try other util, not OBS, jut in case.
ok so are you saying it's worth a try to buy a better capture card and see or was there something you wanted me to try?

Different utils. You can try different software to see if it (capture device) behaves similar. For example Shotcut v221221 (old one) can capture devices to the file. Why this old version? I didn't tried newer, maybe it also works good. #7 in this list:
Requires some skill to create first file but still the job will be done in few clicks. See few posts below.

My 2 cents...

CPU is old & better suited for surfing the web so it just may not work to your expectations.

The iGPU driver is old & should be updated especially since you're running the latest version of OBS.

In Windows Gaming, disable Game Bar & Game DVR (Captures) to save resources.

Hopefully there's some improvement in the 99th percentile. This is from your good log & Audio is definitely on the slow side.

Not much available RAM either. W10 is using roughly 4GB. System may be thrashing at times causing the audio to lag. The system uses Virtual Memory/writes to C drive. You can take some load off the system by writing your recording to another drive if one is available.

I'm not sure I want to mess with my drivers. This is above my knowledge. LOL
The article lays out, with pictures, step by step where to go and what to look for. In this case, we aren't doing anything but checking/changing a default setting (sort of like changing background color on desktop)...

Also, the way you describe it sounds like an abrupt change? Not gradual? That could point to a different problem, though I'm not sure what.

The U model CPU most likely means a battery-life optimized laptop means @strugglingmom could easily be running into thermal throttling... so setting laptop up with clean air flow to vents (if there are such) and maybe even an external fan (exact recommendation _if_ thermal throttling, depends on laptop model specifics)?

Combined with limited RAM? a number of us know how to dive deep into a system an optimize and under-powered system... but that isn't for the feint of heart.
But in terms of basics - Certainly checking the Operating System Auto-start items and disabling those that don't NEED to be running all the time (especially not when trying to convert video), like file sync tools, or ?? A number of Apps (M$ themselves being guilty of this, and thereby encourage others to misbehave as well) set themselves to auto-start (ex, MS Office, Edge, etc) when that isn't needed (and a bad thing on an under-powered system).

Thank you. I will check them out.

Alternative.
How to capture device in Shotcut v22.12.21 in 12 steps:
Screenshots - https://imgur.com/a/Fg88UHs
Connect device to PC, run media playback on the device, pause device if possible, then:
  1. Run Shotcut application
  2. Set new project name, folder, video mode (output mode)
  3. If no suitable video mode available create your own
  4. To create your own video mode type new FPS, resolution, aspect ratio etc into corresponding fields of the "Add Custom Video Mode" window
  5. Click Start button to save the Shotcut project changes
  6. From Shotcut main menu File > Open Other... open capture device selection dialog window (window named "Open Other"),
  7. in this window select type of the capture device,
  8. and specify devices for video and audio signal
  9. Close capture device selection dialog window (named "Open Other") by clicking OK button
  10. From Shotcut main menu File > Export > Video... open video file export dialog window
  11. From export dialog window select encoding preset (MPEG-2, it is old but fast CPU based encoder) and click Capture File button. Shotcut will prompt to you to set the file name and folder where to save your media. And recording of the file starts. The button's name changes to "Stop Capture"
  12. You may un-pause your device if you paused it before. Wait for the device to complete playback and then click Stop Capture button (Shotcut doesn't show preview of the recording process, it is normal, so use your device indicators and timers)
