Filming at high frame rates and its advantages

I have been doing a bit of research looking into the advantages of shooting on a high speed camera. Most cameras that we will be using will be 25-29.7 fps. However, if we really do want to do some experimenting with speed and motion this will have to filmed at a much higher frame rate. For example;

If you film at 25fps, when you reduce it to 50% you will end up with a video that is 12.5fps, not particularly good quality and the slow mo will look not particularly good. However, if you were to film at 50fps, the slowed down footage would end up at 25fps, which is standard filming speed and look normal with the rest of your footage.

The picture above is of the Sony PMW-EX3, the camera used on Jasmine's music video shoot. Aside from being a particularly good camera, on the side there is a dial to change the frame rate so that you can film different frame rates depending on what you intend to do with it in post production.

If we were really serious about filming some slow-mo stuff we could look into hiring a camera like the one above.
