Step 4. On the right part, check the box of "Frame Interpolation", and you can start frame interpolating your video to 60fps, 120fps, 240fps, and even 480fps. Just choose from 2X, 3X, 4X, and 5X to double, triple, quadruple, quintuple the video frame rate.

Set Video FPS in Winxvideo AI

Tips:

  • To achieve the desired frame rate, one can repeat the process multiple times to reach the target frame rate. For instance, selecting 2X twice can convert a 30fps video to 60fps and subsequently to 120fps. This approach yields superior output quality compared to directly choosing 4X.
  • Check Skip Scene Changes or not: Whether to always compare the difference between two frames and not insert the frame if the difference is too large.
  • Create slow-motion video by choosing 2X, 3X, 4X, or 5X to slow down the playback speed. For example, you can create a slow-motion video about the passing through an egg, a water glass, a watermelon, etc.
