Can anyone tell me why my two youtube videos have gone thin! They were ok until a few weeks ago when the picture only covers half the screen. I think one is www.youtube.com/watch?v=THGRqrVAe0o. Any way search Warwick Slade. The original DVD is lost (maybe a godsend)

hmmmm...weird! Never saw that happen before. I see that it tries for about one frame to be 'right', then narrows..

At first play, it looks good for about a second, then resizes the horizontal. If you pause, back up to the start, and replay, the "first second" is also resized. This indicates that the new "size adjustment" has been applied to the whole file by that time.

The SWAG would be that the original upload had an oversize "screen dimension," and YouTube automatically resizes to fit the "display frame." In this case, it's resizing the horizontal but not the vertical, or the horizontal much more than the vertical.

A different "scale factor" might be used by YouTube if your original had an unusual "aspect ratio" - the ratio between total horizontal width and total vertical height. The display frame I see on YouTube is about 5.5" x 4", so YouTube appears to use something like an 11 x 8 aspect (Horiz x Vertical). [That approximates a 5 x 7 picture frame, and my measurements weren't exact.]

This isn't too far from what's common on older monitors, or for cameras (still) that I have; but if you set up the video on one of the newer "wide screen" digital monitors, or if you used a "wide angle" lens in making the videos, the aspect ratio for what you posted might be quite a bit "off" from what YouTube uses to display your video.

An "expected" resizing by YouTube would make the proportionately longer dimension fit and adjust the other direction by the same scale factor. In this case you'd just have "blank bands" either top and bottom or both sides. YouTube may have chosen to do something different, or the resizing that it's supposed to do isn't adjusting correctly (by the same scale factor) in both directions.

You might find some help in YouTube's FAQ on posting if you look for "aspect ratio" or something similar. If something else is happening, eliminating this as a possibility will simplify finding the real culprit(s).

I see a fair number of pics at other sites where people have "resized" but forgot to set "lock aspect ratio" or just resized x but not y. They look similar.

This happens to me with any and every youtube video on one computer, not on the other. Someone must have a way to fix it.

Thanks for suggestions. I will investigate. The odd thing is that it was alright for the first 6 months or so and now it's wrong on all computers.
Thanks again
Warwick

The same with mine Warwick Slade, some of mine have slimmed down, ok when I first posted them.
