Things to keep in mind before recording a video to use the slow motion effect in Premiere Pro

If you are recording a video clip to which you will give a slow motion effect, we recommend keeping these aspects in mind to obtain the best results:

  • Record the video in 60 FPS or more. That way, you will have more frames per second and the slow motion video will not look choppy.
  • Shutter speed must be twice the FPS used. That way, if you’re going to shoot at 60 FPS, you should be working with a shutter speed of 1/125.
  • Think carefully about what takes you are going to record for slow motion. It is worth lengthening the clip!
  • If you are going to shoot indoors, be careful with the lighting. If you use low-quality light bulbs, the video may flicker or flickering that they produce. Of course with Premiere you can improve low light so that lighting is not a problem.
  • When shooting with many frames, noise or grain may increase. Keep this in mind when working in low-light environments.
  • By last, do not abuse the effect. If you use it a lot during your video, it will become monotonous and boring.
