In this second tutorial on animating an IK character Andrew Devis shows us how to create and refine a walk cycle with our IK controlled character such that it walks in time with the music we had set up in the previous tutorial.

Andrew shows how to set up the timeline and create, copy and paste keyframes between layers to quickly set up the animation and how to use the IK controllers to move things quickly and easily on screen. He then goes on to show how to apply an expression to each layer with keyframes and then apply it quickly to all animated properties in your comp. This expression ensures that only one walk cycle (i.e. 2 steps) is all that is needed to be keyframed but will still continue to animate for however long your composition may be.

Lastly, Andrew shows how to refine small issues with the animation to get the best results possible.

Hi Andrew,

thanks for this. With the help of your tutorials it was fairly easy to create a walking character!

However, I encounter a problem by making him walk horizontally across the screen. He seems to be sliding on the floor with every step. It looks quite funny, but it is not the effect I am looking for :-)

Could it be due to the fact that I animate the x-motion separately? I did as you said and have a master controller animate the character across the screen. However, it seems to me that the x-motion should stop when he puts down a foot...

Do you happen to have an easy solution to this?

I really enjoy watching your tutorials!

Hi David

It's been a while since I did the tutorial but from what I can remember I think I animated the character to walk on the spot which would give you the foot sliding thing. The reason for this is that you get the illusion of walking if you move the background as the character takes each step. By moving the background it looks like the character is walking through it. If the background stays still the character will look like he is taking a sliding walk in place.

If you want the character move as it walks you will need to move the master control and have the character start on one side of the screen and move to the other side.

Hope I've understood?? All the best
Andrew

Hi Andrew,

thanks for your quick reply. What I was trying to say is that even though I did animate the master control I kept getting a drift. The character takes steps and moves across the screen alright but he slides back and forth with every step.

In the meantime I tried introduce more key frames to both the legs and the master control with the result that I got rid of the drift but the movements got more jerky, which doesn't look very natural, either...

Maybe I am just too demanding? I do not have a deadline, so there is no pressure. I am just wondering how to make this look natural.

Thanks for the idea of the moving background. I will try that next.

Cheers,

David

I have the same issue. I want my guy to walk off screen but there's drift. Did you ever figure out a good way to adjust that?

I haven't really. But I haven't tried the moving background. I remember playing with the main sliders and got some improvement. Perhaps the best is just to play around until you get a result you like.

This tutorial is both a follow-on tutorial to Andrew's previous tutorials on IK controllers in After Effects and a helpful stand-alone tutorial showing how to define a beat range to use as a guide to animation in After Effects. To start with Andrew shows how to use a simple expression to deal with a potential problem of controllers scaling your objects. Then Andrew shows how to find and download sample music which can be used to base your animation on. He goes on to discuss the difficulty of matching frame rates with audio sample rate and then shows how to get a reasonably close 'loop' in both After Effects and especially in Audition.

In this video tutorial you will learn how to use the Neat Video plug-in for multiple applications. Although demonstrated in After Effects, the work-flow is essentially the same for all these applications: After Effects, Premiere Pro, Final Cut Pro, Motion, Nuke, Fusion, Vegas Pro, etc. This powerful but simple to use plug-in can clean up noisy footage by applying a sophisticated and advanced algorithm to work out what's noise and what's details in your footage and then remove just the noise. This is done by profiling the noise properties in an area of a video frame without visible features. Once the noise has been profiled, Neat Video is guided by this profile to reduce and eliminate noise while not touching the video details. Although mostly automatic, Neat Video still leaves you with total control over the amount of filtering you apply and even offers optional sharpening (without sharpening the noise) should you wish it.
