Here is some text, before we have a video. I kind of wonder how I want to handle portrait videos. They're kind of annoying. Maybe they're not worth putting too much effort into? Oh, but wait – I need to know the video dimensions anyway, or else I'd mess up the aspect ratio. Hmm. I hate to overly re-invent that wheel.

First video - 4:3

This is a longish caption for a video. I intentionally made it multi-line, so as to show that the extra spaces we get don't particularly hurt. I want to keep typing a bit more, to make it longer. OK, there, that's enough.

OK, that's the first video.

Second video - HD resolution, portrait

Not a terribly exciting video

Third video - HD, landscape, no caption

End

That's all, folks!
