Yep!
I think your have a glazed clutch disc and possibly some hot spots on both the pressure plate and the flywheel surfaces.

How many miles or kilometers on this clutch or is it an original?
The original clutches on these cars go far longer than replacements due to all the things being new.

Oil seals and usage take their tolls over time. Do you have oil leakage underneath?
And of course “time” always passes on its “deeds” to everything. (:)
All we can do is train ourselves to live with it or around it, as best we can!
Nothing gets out of life alive and unscathed or your not living!

What you want to do is refrain from ever feathering the clutch pedal during operation.
You mentioned doing that in the last video.
Get your foot off the pedal as soon as you can after any take offs.

It’s best to do not idle for long periods of time with the pedal in either as this prematurely wears on the throw out bearing.
Yours is still of if you do not hear anything while depressing the clutch pedal.
Leaving the foot on the pedal can cause slippages and premature wearing of the disc but more importantly slick spots on all four surfaces that make up the friction clutch pack.

The good news you have a warning, that it has worn, but you will still get more mileage or kilometers on the car until it won’t stall the engine against a load or pull itself when passing another vehicle in a hurry!

Now Dave Stevens might be the 900 man worth following up on in your hunt for a noise!
