overheating during timelapse

A 2 minute video (not a 2' timelapse) - irrespective of the original time lapse interval - will have fps*60 frames per minute.

Sorry, you are making no sense to me. This has nothing to do with shutter wear when shooting timelapse photos, which was the thrust of your posts #3 and #7.

Ok, I'll try to be more clear.
In order to get a video of a certain length and at an acceptable framerate you have to shoot a lot of pictures.
There are many timelapses here on the forum which are about a minute long and were made from nearly 2000 images.
A shutter life expectancy is about 100'000 shots; some break earlier, some later.
But shooting 2000 pictures for just one video puts a significant wear on the shutter.

In the preceding post when using the word "video" I meant "the final product" of the timelapse (which is a video), not the video function of the camera.
And when I said "timelapse" I meant the actual process, with a picture every so and so minutes.

I've kind of gotten lost here. Are we talking about the shutter in the lens rather than the shutter in the camera body?

If so, what is the advantage of using the shutter in the lens rather than using the shutter in the camera body??

The Q has no body shutter. Shutters are in the lens.
The K-01 has no mirror, but has a body shutter.
LB's view is that using a DSLR or a DSLM for Time Lapse isn't a good idea due to shutter actuation wear.
I completely disagree with him and his reasoning. But that's me

How does the Q take pictures with an adapted lens?
Could you not use an adapted lens to do time lapse?

With adapted lenses it uses an electronic shutter just like PnS cams do.
