# How to increase frame rate 16FPS to 30FPS in ComfyUI with ComfyUI-Frame-Interpolation node. Easy !

## Summary

This tutorial demonstrates how to increase video frame rate from 16 FPS to 30 FPS in ComfyUI using the ComfyUI-Frame-Interpolation node. Frame interpolation creates new frames between existing ones to make video playback smoother.

### Key Points

- **Comparison of 16 FPS vs 30 FPS** [0:00] — 81 frames at 16 FPS is jagged, while the same frames at 30 FPS is smoother and better.
- **What is frame interpolation?** [0:24] — Frame interpolation creates new frames between existing ones to make video playback smoother and more fluid.
- **Installing the interpolation node** [0:40] — Go to Manager > Custom Nodes Manager, search 'interpolation', and install 'ComfyUI Frame Interpolation'.
- **Building the workflow** [1:06] — Use three nodes: Video Upload, VFI RIFE (frame interpolation), and Video Combine (output). Set output to 30 FPS and H.264.
- **Integrating with existing workflow** [2:51] — Add the interpolation and combine nodes to an existing text-to-video workflow to automatically create a 30 FPS output.

### Conclusion

Frame interpolation in ComfyUI is an easy way to improve video smoothness. The method works well for the creator and may work for others too.

## Transcript

Hello folks. On the left is 81 frames at
16 frames pers and on the right is the
same 81 frames at 30 frames pers. The
right is clearly smoother, less jaggedy,
much better. So if you're creating
videos in Comfy UI at 16 frames pers,
there's a very easy way to upscale these
to 30 frames a second.
What is frame interpolation? Frame
interpolation is a video processing
technique that creates new frames to
insert between existing ones, making
video playback appear smoother and more
fluid. So, it's actually making up fake
frames in between.
All right. Firstly, you want to check
that you've actually got the
interpolation node. So, click on manager
and custom nodes manager. In the search,
you type interpolation.
And this is the one you want here. Come
for UI frame interpolation. I've already
got it installed. But if it's not
installed for you, then do the install
like it says on these other ones. Okay.
Once that's installed,
let's build a quick workflow with the
three nodes we need. We're going to use
a video upload node, the conversion
node, and then output node. So, we're
going to double click
uh video
upload.
Yeah. And have that one there. There we
go. Now, we want our frame
interpolation. So, right click, add
node,
come UI frame interpolation. VFI
re VFI. There it is. Join that to that.
And now we want an output. So, we're
going to go for a scroll down the video
helper suite and the video combine.
Turn that to six uh 30 frames.
There we go. Change that to H.264.
Uh, and we're done. So, let's load up.
This is one I was working on earlier. My
Duke Nukem video. Never made the cut.
So, let's choose a video. So, our 16
frames per second. There we go. And that
is it. All we got to do is run it.
Okay, that's um that's finished. There's
our 30 frames. So, let's go and look at
that in Explorer.
Here we go. That one there.
Lovely. Tools,
codeex. Here we go. 30 frames pers.
Job done.
Okay. So, let's join that to um an
existing workflow. So, here's our I got
a text to video workflow here using
Fusion X. Um it's creating a 81 frame
output 640x 640 just for the purpose of
demonstration and it's a 16 um frames
per second. So all we've got to do is
rightclick add node
come UI frame interpolation VFI
rife vfi. There it is. There you join
the VA code onto there. Add a video
combine.
Where are we down here? Video helper
suite video combine.
Join that to that.
Turn that to 30
frames pers.
Uh, turn that to
H.264 output.
Sorry, wrong one. There we go. That one
there. And it will not only will it
create the 16 frames per second one, it
will then go on to create the 30 frames
per second output. I hope that was a
useful exercise, guys. Um, it certainly
made my video outputs better now, and
that's what I'm going to be using from
now on. Uh, it may not be the best way
to do things, but it's the way that I
found that works for me. So, I hope it
works for you, too. Goodbye.
