What is Frame Interpolation?

Made this a few years back to demo frame interpolation frame blending

Obviously, the technique doesn't work well with complex backgrounds, low resolution, and low framerate footage (hence the 'bubbling' and blurring around the actors).

Sure nothing beats 60fps recording. But trust me; Eventually interpolation programs will be a hell of a lot more complex and optimized. Yeh there's always limits. But we haven't reached them yet.

[OnlyVideoGuyOnEarth]

That's so cool, I would actually remove frames from normal footage and replace them with interpolation at normal speed to achieve that warpy effect.

[GoldTrousers]

in 10 years this technology will be flawless. you know it will :P

Some algorithms work better than others. The bubbling around the subjects can be reduced by some methods where you can go in and carefully tweak how the motion is estimated. In the end, you can always go in and frame-by-frame edit the images to remove much of that. It's obviously a labor intensive process.

The best way to do it would be to use a high speed camera to begin with.

How do I perform frame interpolation
And what program do I use

[MichaelForenza]

@gamefreak648 you really can't. If you try and stretch the video, you are taking each frame and spacing it out further and further apart making gaps and spaces between the footage (see the beginning of the video under "Time Remapping"). Frame interpolation is a method that uses an algorithm to analyze the footage and predict how those gaps should be filled in. I don't know of any other way to slow footage down besides getting a high speed camera.

Frame blending looks really sexy in FPS games

I think blending is shit. It also affects required bitrate, cause motion detection in p-frames is no more accurate as before (because of bleinding). But interpolation is awesome. Frames are distinct.

In 10 years even the best algorithms will still bump against the same fundamental limits. The most ironical thing about frame interpolation is that it cannot work when it is needed the most: when stuff is moving so fast that there is no way to reconstruct the in-between-frames. If you want proper 60fps footage, film it at 60fps.

Between LG Trumotion, SONY Motionflow and SAMGSUNG Clearmotion, does anyone know which one is better ?

[MichaelForenza]

@LanceCampeau I use Adobe After Effects.

[Tscherdx]

How did you made the effect, that it slows down to slow motion instead of a jumpy change from normal speed to slomo? :)

[TopiasSalakka]

There is a software for Windows that does frame interpolation on the fly. Youtube videos look super smooth with it. :)

[NeatNit]

Is the motion interpolation used in this video the real effect, like maybe a higher frame rate TV might have when its implementation of motion interpolation is active? Or is this just some sort of "artist's rendition" or something like that?

[FoxBoi]

can i make a 30 fps video and make it 60 fps with frame interpolation and then play it at half speed and do it over and over again? how would this even look? xD

[Dantai]

Can you link the video this footage is from?

[videoreborn]

May I know if you are familiar with any of the algorithms being used? Thanks.

[LanceCampeau]

What software are you using for the frame interpolation?

[kezadrone]

Very high shutter rate to eliminate motion blur then interpolate that.

[jaysmith]

What does 'ironical' mean, exactly? OHHHH! You meant 'ironic', didn't you?
