The lack of fixed height for video thumbnails makes them load a little chaotic, since the browser doesn't preserve their height until the thumbnails have loaded & then reshuffles the entire already-rendered contents to fit them in once their sizes are known.
Given how the vast majority of thumbnails exceed 150px (and are then scaled back to that height), I think it would make sense to set a fixed 150px height.
Added benefit: all video titles would be at a consistent position, regardless of the video aspect ratio.
Here are a few images to illustrate what would change:
1. Notice how the page loads much cleaner, immediately reserving the thumbnails space, instead of continuously pushing around the other elements once thumbs are loaded
2. Notice, at the end, how the 2nd thumbnail now has the same height (with black bars) as the other videos. This will affect videos exceeding a 252:150 (which is close to 16:9) aspect ratio. IMO, this is desirable (it's consistent with black bar treatment for landscape videos, and the titles are now in a consistent place)

Acceptance criteria:
[] Video thumbnails have a fixed height of 150px
Note: I already have a patch for this (while working on something else), but putting in backlog so design can assess whether this is desirable. If ok, this can move straight to "In Code Review".
