Sorry guys. I recently bought a computer software named SVP - Smooth Video Project. It claims to be able to convert video frame rate from 30fps to the higher 60fps. But I could find no differences after the conversion process. I know the frame rate means the number of pictures flashing by per second. So, is it the frame interpolation that causes that distortion in video image? This is the software i used to smooth video:http://www.videoconverterfactory.com/tips/smooth-video.html
