The Resize Vimeo pluggin for WordPress does exactly what you would expect — it resizes Vimeo videos. I created this plugin, because I plan to start doing some more videos and I wanted any videos that I post on this site to look good. I really like how the Vimeo player looks, but the standard width only goes about half way across the content area they they’re in right now. I thought this looked really tacky, so I decided to experiment and see if it was possible to make the player bigger. Turns out that the player actually gets bigger very nicely.
This plugin gets the current dimensions of the video you post and increases them to a set width and increases the height accordingly, keeping the same width-height ratio as the original player.
We now have an admin menu that lets you choose the size of the video player
If you change the width of your content are in the plugin it should resize them automatically for your site. make a read me text file possibly and explain that. good plugin idea though. it's really annoying to have to manually figure out the dimensions of a flash player.
I'm not sure I exactly understand what you are saying in that first sentence. Do you mean that the video width should depend on the width of the content area? I could do that. I could add an option in the admin menu to automatically find the width and a setting for padding on that with a default of 10px or so. Then it would just take a little jquery to get the width of the div that we're in.
I meant that who installs this can go into the code and change the width in the plugin to the width of the content area in their theme.
