Most cameras and many older videos record at 24, 25 or 30 frames per second. Converting to 60 fps adds a new frame between every pair of existing frames, calculated from the motion between them, so pans, sports and moving objects look smoother. The video keeps its length and its sound.
How to convert a video to 60 fps
- Upload the video (MP4, MOV, MKV, WebM, AVI, WMV, MPEG, TS and more; up to 1 GB) or an animated GIF.
- A higher frame rate, 60 fps and Motion interpolation are already chosen. 30 and 50 fps are there too: 50 fps suits 25 fps footage, as every other frame stays an original.
- Start, and download the 60 fps video.
What you get
- New frames, not copies: motion interpolation estimates where each part of the picture moves and draws it halfway. Simply changing the frame rate number would only repeat frames, which looks no smoother.
- The same length and sound: the main sound track is kept, unchanged where the format allows.
- Format: MP4, MOV, MKV and WebM stay in their format; other formats become MP4, re-encoded at high quality. Upright phone videos stay upright.
- GIFs give a smoother GIF, at up to 50 fps (the fastest a GIF can play), with the loop setting and transparency kept.
What to expect
Steady, clear motion (a pan across a landscape, a car driving by, a slow-moving crowd) comes out very smooth. Fast or complex motion, fine repeating patterns such as fences, and objects passing in front of each other can show warping or smeared edges, because their movement can't be estimated exactly. Scene cuts are detected and left as cuts. If warping shows, choose Frame blending: it mixes neighbouring frames instead, never warps, and looks slightly softer.
Limits
Motion interpolation is slow. Pictures larger than 720p are made smaller to 720p first, and one job can produce about 1 minute of 720p at 60 fps, or about 2 minutes of 480p. Frame blending works up to 1080p and allows about 20 times as much. For a longer video, cut the part you need first with the video trimmer.
