Load your video, choose a target frame rate, and export. The re-timed file downloads once processing finishes.
Lowering from 60fps to 30fps roughly halves the file size for the same duration and matches the frame rate most social platforms and TVs expect, at the cost of slightly less smooth motion.
You can convert to a higher frame rate, but the tool duplicates or blends existing frames to reach it rather than inventing genuinely new motion detail — true frame interpolation needs specialised software.
24fps is the traditional cinematic frame rate, giving footage a distinct film-like motion quality compared with the smoother look of 30fps or 60fps.
