Do you look weird to yourself on video?

I just watched a work related tape that was done months ago (I intentionally avoid watching or listening to myself after being recorded but Netflix is still in the mail...And I had a six-pack) where I presented a mind numbing subject matter in a fairly decent way.

Needless to say I looked rather different that I visualize myself normally...

I almost looked stocky which I'm not, not that there's anything wrong with stocky!

I totally believe them. Oddly, I can look slim in picture, but NEVER on film.

A short one but gawd...

Hehe

... like I do in pictures, I'd jump off a cliff :)

Because all we usually see is our mirror image, where everything is on the other side, like the hair part, the other eye, etc. . . . .

I'm used to it, by now, but it can still seem kind of not quite me, especially when I haven't been on camera in any way for a while.

Ditto recorded voice or voice processed through a microphone -- things sound a lot different over a speaker-mic system, probably mainly because of the reverb.

Photos, even, can make us look radically different than what we see in the mirror. Maybe it's as simple as the fact that our eyes are positioned such that we're looking slightly downward over reflection of our bodies, at least within close range of a mirror, whereas a photo (or video clip) more often probably shows us either square-on or from slightly below (or very much below, if a TV crew or the like is at work...dramatic angle, though often not especially flattering to the subject). Maybe that's why they say the camera adds ten pounds...

It's the video that's got me looking like a short linebacker!

However your ideas about perception sound pretty tight.
