Hello,


I shot this video on a Panasonic TM900 at 1080p 59,94FPS.
http://reels.creativecow.net/film/accelerate-and-loop-plz
https://www.sendspace.com/file/qe3iak

I want to speed it up on after effects and loop it forever ("pingpong" style) at the point the face becomes a blur and the body is still visible, moving smoothly (such as that effect from the horror movie 'The Ring', where everyone's face is blurred up).

How is it possible? I have basic knowledge of After Effects, and I've tried lookin on the forum, but none of the explanations worked for me.

I'm running a intel core i7 Windows 8 system with Creative Cloud subscription.

Thank you so much for the help!
Leandro.

I'm going to focus on the head part, a stillish body would just require another layer and some masking.

So take your video, drop it into a comp and enable time remap. Go to the end, her head is facing right, now go back and find a similiar position, for me it was at 5:52:22. Move these 2 frames closer together to get your final speed. Then just add this pingpong expression which just says you the last 2 frames to pingpong(go back 1 keyframe).

loopOut(type = "pingpong", numKeyframes = 1)

Drop the entire thing into a final comp and add the CC Force Motion Blur effect and ramp it up over time. If anything's unclear check out my quick & dirty example project, it should give you a start on how to do this:

Tyvm for your help Johnny! You really helped me with this job.
I downloaded your aep and I'm trying to ramp it up as you said.

I'll post more details if I need to.

Thx again!
Leandro
