A still image always creates an image or thumbnail on a wiki page (unless ":File" is used). The "thumb" parameter for a still image is used to cause the article to show an image (thumbnail) of the specified size, with no frame or caption text. But a thumbnail or image is still shown. Video should be treated the same. Video should be capable of inclusion without a frame like still images (there are places a frame would be unsightly). But including a video without the thumb parameter behaves badly inconsistently. It does not create a frameless captionless thumbnail + "play" control. In fact there is no obvious way to do this for video. It probably should. Examples: compare the rendering of these three markups: [[File:SN1994D.jpg|x150px]] [[File:Black hole lensing web.gif|x150px]] [[File:Millisecond pulsar and accretion disk - NASA animation (low res).ogv|x150px]] The still image and animated still image both render framelessly. The video does not. Unlike still images and anmimated GIF's, there is no way to produce a thumbnail for the video without also adding a frame.
Typo - should read "The 'thumb' parameter for a still image is _omitted_ to cause..."
This is fixed with my fixes for height parsing that I have in store. There is one other difference, an oggplayer is always a block elements, while a frameless image is an inline element. I'm not sure we would want to change that at this time.
If the visual appearance is consistent for both, then the fact they use different structures at HTML level isn't much of an issue.
