How to make a 60, 120 or 144 fps wallpaper from a 30 fps video

Most videos are 24 or 30 frames per second, but many monitors refresh 120, 144 or even 165 times a second. On a fast screen a 30 fps wallpaper can look a little choppy, especially slow panning shots. Frame interpolation fixes that.

Duplicated frames vs real in-between frames

Simply converting 30 fps to 120 fps repeats each frame four times: the file says 120 fps but the motion is exactly as choppy as before. Frame interpolation instead works out how everything moves between two frames and draws brand-new frames in between. Wallsmith uses RIFE, an AI model made for this.

How to do it in Wallsmith

1. Open your clip.
2. On the Enhance tab, under Frame rate, pick 60, 120 or 144. If your screen runs at another rate (165 Hz, for example), Wallsmith offers that too.
3. Export as usual. Scene cuts are detected and never blended, so a cut stays a clean cut.

Free or Pro? Higher frame rates are part of Wallsmith Pro ($5 once). The free version keeps the original frame rate.

Make sure it plays at full speed

• Wallpaper Engine has its own frame-rate limit in its settings (Performance). Set it at least as high as your wallpaper, or the extra frames are skipped.
• Pick the rate your monitor really runs at. A 144 fps wallpaper on a 60 Hz screen only costs extra GPU time.
• Higher frame rates mean bigger files. 60 fps is a great middle ground for 60 Hz and 120 Hz screens alike.
