What does your Video SEO plugin actually do?
It goes through a series of steps, as soon as you update a post that you put a video in:
It recognises the video and, depending on whether it's a self-hosted video or hosted on a site like Vimeo, determines what to do;
If it's for instance hosted on Vimeo, it'll retrieve the video details from the Vimeo API;
It'll determine which thumbnail to attach to the video and what the duration of the video is;
It then saves all this metadata so that you get a video snippet in the snippet preview AND a video XML sitemap entry is generated for the post / page.
It does all that on the fly, as soon as the plugin is activated you only have to add a video to a post and it'll automatically recognize it and go through those steps for you.

The choice was between WP Super Cache, W3 Total Cache and Hyper Cache. This article documents my admittedly limited testing of these plugins and the decision I made as a result."
