If you want to convert the videos to other formats easily or change the frame to a fluent one, this tool may help you: http://www.videoconverterfactory.com/tips/wv-converter.html

I use online video converters because I only convert short screen recording. If you need to convert huge files you have to download something, but I can't help you.
