Lens Correction For Video
If you have Photoshop Extended (CS3 or higher), you have the ability to open and edit video. In addition to any filter or adjustment layer, you can lens correct video! Just turn the layer into a smart object (Layer>Smart Objects>Convert to Smart Object) and any filter you add (such as Filter>Lens Correction) will become a smart filter and carry over to each frame. Load the Motion workspace (Window>Workspace>Motion) to quickly prompt the video-specific tools.
