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

[00:00] Hello folks. On the left is 81 frames at

[00:03] 16 frames pers and on the right is the

[00:06] same 81 frames at 30 frames pers. The

[00:10] right is clearly smoother, less jaggedy,

[00:13] much better. So if you're creating

[00:15] videos in Comfy UI at 16 frames pers,

[00:19] there's a very easy way to upscale these

[00:21] to 30 frames a second.

[00:24] What is frame interpolation? Frame

[00:26] interpolation is a video processing

[00:28] technique that creates new frames to

[00:30] insert between existing ones, making

[00:33] video playback appear smoother and more

[00:35] fluid. So, it's actually making up fake

[00:38] frames in between.

[00:40] All right. Firstly, you want to check

[00:42] that you've actually got the

[00:43] interpolation node. So, click on manager

[00:47] and custom nodes manager. In the search,

[00:50] you type interpolation.

[00:55] And this is the one you want here. Come

[00:57] for UI frame interpolation. I've already

[01:00] got it installed. But if it's not

[01:02] installed for you, then do the install

[01:04] like it says on these other ones. Okay.

[01:06] Once that's installed,

[01:10] let's build a quick workflow with the

[01:11] three nodes we need. We're going to use

[01:13] a video upload node, the conversion

[01:15] node, and then output node. So, we're

[01:18] going to double click

[01:21] uh video

[01:24] upload.

[01:25] Yeah. And have that one there. There we

[01:28] go. Now, we want our frame

[01:30] interpolation. So, right click, add

[01:33] node,

[01:35] come UI frame interpolation. VFI

[01:39] re VFI. There it is. Join that to that.

[01:44] And now we want an output. So, we're

[01:47] going to go for a scroll down the video

[01:50] helper suite and the video combine.

[01:54] Turn that to six uh 30 frames.

[01:58] There we go. Change that to H.264.

[02:03] Uh, and we're done. So, let's load up.

[02:06] This is one I was working on earlier. My

[02:08] Duke Nukem video. Never made the cut.

[02:11] So, let's choose a video. So, our 16

[02:14] frames per second. There we go. And that

[02:17] is it. All we got to do is run it.

[02:26] Okay, that's um that's finished. There's

[02:28] our 30 frames. So, let's go and look at

[02:30] that in Explorer.

[02:34] Here we go. That one there.

[02:40] Lovely. Tools,

[02:42] codeex. Here we go. 30 frames pers.

[02:48] Job done.

[02:51] Okay. So, let's join that to um an

[02:54] existing workflow. So, here's our I got

[02:56] a text to video workflow here using

[02:58] Fusion X. Um it's creating a 81 frame

[03:03] output 640x 640 just for the purpose of

[03:07] demonstration and it's a 16 um frames

[03:10] per second. So all we've got to do is

[03:15] rightclick add node

[03:19] come UI frame interpolation VFI

[03:23] rife vfi. There it is. There you join

[03:26] the VA code onto there. Add a video

[03:30] combine.

[03:33] Where are we down here? Video helper

[03:35] suite video combine.

[03:38] Join that to that.

[03:40] Turn that to 30

[03:42] frames pers.

[03:45] Uh, turn that to

[03:48] H.264 output.

[03:52] Sorry, wrong one. There we go. That one

[03:54] there. And it will not only will it

[03:56] create the 16 frames per second one, it

[03:58] will then go on to create the 30 frames

[04:00] per second output. I hope that was a

[04:03] useful exercise, guys. Um, it certainly

[04:05] made my video outputs better now, and

[04:07] that's what I'm going to be using from

[04:09] now on. Uh, it may not be the best way

[04:11] to do things, but it's the way that I

[04:13] found that works for me. So, I hope it

[04:16] works for you, too. Goodbye.
