Need Video Editing Software that..

I need a program that will allow me to easily insert an image in the exact middle of my videos.

I am going to make 20 videos, each with a different image for the exact middle. I have 4 videos that I am going to use, and the images in the middle will make them all "different" so I don't have an exact duplicate.

The image needs to display for just a few seconds, but be showing at the exact middle. It will need to output to a youtube supported video filetype so I don't have to encode it with yet another program. Hopefully a batch mode so I can do multiple videos at the same time.

FYI - I am unable to use Video Watermark Factory as I am on Vista.

SO any suggestions on what app will insert my images into the exact middle of my videos?

Didn't tried this put this has been posted today:

I use Sony Vegas to do all my editing.

It let you cut your vid in half and insert anything you want, pics, text, etc.

I code it as wmv which is supported by YT.

It doesn't work in batch but does save your work as project.
I set it up once than reload the clean project for every vid, insert a different vid and image and rinse and repeat.

It's been posted here, just do a search for it.

Thanks, I can do the same in Camtasia Studio 6 or Windows Movie Maker, I was just trying to automate the process. It takes like 2-5 minutes to encode each video. So its gonna take like 2 hours to do lol.
