Technically, yes. Slowing down footage in post-production may have varied results though. We encourage you to get an opinion from your post-production house about it – but whenever possible, it is a great idea to shoot everything so that real-time footage is created. Trying to fix problems with frame interpolation might cost more time and money than doing it right in-camera.
Some of the biggest problems with slowing down footage in editing include, distortion of the background, weird visual blurs on details, a distorting “tearing” effect when parts of a visual element is either revealed or obscured.
