Indeed, none of this was shot particularly well. I'd prefer it be shot closer and in landscape to conform to the shape of the OS.
Obtrusive - noticeable or prominent in an unwelcome or intrusive manner. The letter-boxing is large, surrounds the video, and is unwelcome by most viewers. My use of the word was apposite. The video player's limitation should be taken into account by the person filming; that's why I said designers should understand their mediums.
I agree, your alterations brought nothing to my viewing ease. The original video wasn't shot in landscape, which would've been preferable. As for getting my money's worth out of my monitor, this is solely a fixation you've attributed to me. I don't know why.
I doubt the person who shot this is a designer so your entire premise isn't very apt. This person simply filmed something to share it with the rest of us and instead of being grateful, people here with black bar issues had to whine about how it was filmed and claim that movies should NEVER be filmed in portrait which is totally untrue as I commonly design movies for display on vertical LED walls and Times Square is awash with all sorts of shapes and sizes of movies. Needing everything filmed in landscape is just an artificial requirement for certain people. Like you said, the magnification of the subject was the important factor for viewability, NOT whether the final movie was tall or wide. More tabletop in the frame doesn't help ANYONE see what's going on.
I mentioned getting your money's worth out of your monitor because that is a common statement by people who complain about letterboxing on movies that are filmed in wide format. The same people who make channels like HBO ruin movies by cropping them to fill tv screens.
