The problem with converting to OGV is that you're going to necessarily exclude a healthy chunk of people using Apple devices. Those desktop users who are running less than Mavericks might be able to see the video, provided they have the right extensions to Quicktime installed, but no one above 10.9.0 will be able to see OGV in Safari. They'll have to run desktop Chrome or Firefox just to see your video. In fact, they won't even see your poster image. For me, 452's post is a big blank space with a question mark in the middle. In other words, using OGV would break any page design for Safari users.

And even if you can dismiss Safari desktop users as being insignificant, you can't be so flippant about iOS users. All iOS browsers — even Chrome and Firefox — are based on Safari. So by converting to OGV and uploading directly to Wikia, you're excluding everyone who's running and iPad or iPhone with iOS 7. I don't think you really want to exclude quite that many people.

The far better option is to create a YouTube account, upload to YouTube, then cut and paste the YouTube URL into the Wikia "Add Video" dialogue box. Remember, you can upload to YouTube in such a way that no one sees your upload at YouTube, but you can still embed it here at Wikia.
