What is Frame Interpolation
Frame interpolation inserts additional frames into footage to make it look smoother.
[0:10]
Installing the Custom Node
Go to Manager, install custom nodes, search 'interpolation', and install the ComfyUI Frame Interpolation custom node.
[0:26]
Example Workflow Overview
A two-second video (60 frames) of waving passes through control nets, textual prompts, and Animate Diff to create a short video.

Adding Frame Interpolation Node
Add Node > ComfyUI Frame Interpolation > VFI > Film VFI. Connect to frames and video combine node.
[1:07]
Settings for Smooth Output
Use multiplier of 2 to double frames, set FPS to 60, create preview node, set to H264 for quality.
[1:30]
Result and Comparison
After 40 seconds, 119 frames created (~60 FPS). Side-by-side shows smoother animation compared to original 30 FPS.
[1:56]
Other Interpolation Methods
Multiple methods available; testing showed similar results to Film VFI.

[00:00] Frame interpolation is a video processing

[00:45] To do this, it's fairly straightforward. Go
[00:52] "VFI", and then select "Film VFI".
[00:59] also bring in the video combine custom node
[01:07] connect this here. Since we're going to use
[01:14] double the number of frames, go ahead and
[01:21] create a preview node for review and set this to
[01:30] After 40 seconds, it created a total of 119
[01:38] last extra frame, but it's roughly about
[01:44] side by side. As you can see, it's a little
