[0:00] Frame interpolation is a video processing 
technique that inserts additional frames  
[0:04] into your footage to make it look much smoother. 
Here's how you can do it within Comfy UI. First,  
[0:10] you're going to want to go to your manager 
and then install custom nodes. Then,  
[0:15] search the term "interpolation". 
Next, install this Comfy UI frame  
[0:21] interpolation custom node. Once that's 
installed, we can add it to our workflow.
[0:26] Just to give you a brief, high-level 
summary: I have two-second video footage  
[0:30] that's a total of 60 frames of myself waving. 
This passes through a couple of control nets,  
[0:34] along with textual prompts and "Animate 
Dip", to create this short form video. Now,  
[0:40] while this video looks good, frame 
interpolation will make it look even better.
[0:45] To do this, it's fairly straightforward. Go 
to "Add Node", "Comfy UI Frame Interpolation",  
[0:52] "VFI", and then select "Film VFI". 
Next, connect this to the frames and  
[0:59] also bring in the video combine custom node 
to stitch all the images together. After that,  
[1:07] connect this here. Since we're going to use 
a multiplier of two, which will basically  
[1:14] double the number of frames, go ahead and 
increase the frames per second to 60. Also,  
[1:21] create a preview node for review and set this to 
H264 for better quality. Then, cue the prompt.
[1:30] After 40 seconds, it created a total of 119 
frames. There is some math that drops that  
[1:38] last extra frame, but it's roughly about 
60 frames per second. Here's our animation  
[1:44] side by side. As you can see, it's a little 
smoother compared to our original 30 frames  
[1:50] per second output. It is a very quick and 
easy way to really smooth out animations.
[1:56] Now, I want to touch on the other frame 
interpolation methods available within this custom  
[2:02] node, as well as some of the additional options. 
As you can see, there are quite a few that you can  
[2:48] test against. I recommend testing this for all 
sorts of different animations. However, I found  
[2:57] that the results weren't really all that different 
to the original film VFI that I had done earlier.
[3:07] Lastly, I want to mention the GMFSS Fortuna VFI, 
which is specifically designed for hand-drawn  
[3:15] cartoons or anime animations. If that's 
the type of artwork that you're creating  
[3:20] with a Comfy UI workflow, you might want 
to use that interpolation method instead.
[3:27] That's all for adding frame interpolation 
to your workflow. If you have any questions,  
[3:31] please leave them in the comment section below. 
This entire workflow is available to download,  
[3:36] so you can play with it and incorporate 
it into your personal workflow.
