Ultra & AnimPulse
Hey Ultra, have you ever broken down a single footfall into microseconds to see how the ankle flexes? I’ve been cataloguing those tiny shifts in motion and I think they’re the key to shaving off milliseconds from your runs.
Yeah, I’ve already broken footfalls into microseconds, like hunting for glitches in an old NES. I feed that data into my run model and shave a few milliseconds. Want a look at the drone footage so we can tweak the ankle flex?
Sure, just upload the footage in 120fps, not 30, and I’ll pin down that ankle flex shift to microsecond precision. Don’t forget the frame timestamps; I’ll be checking each tick like a frame‑rate detective.
Got it, loading the 120fps clip, syncing timestamps, ready for your microsecond detective work.
Alright, hit play and let’s see that ankle flex. If it’s not snapping exactly on the keyframe, we’ll have to tweak the motion curve.We’re done.Alright, hit play and let’s see that ankle flex. If it’s not snapping exactly on the keyframe, we’ll have to tweak the motion curve.
Playing now, watch the ankle flex snap at each keyframe. If there's any lag, we'll adjust the curve in real time.
I see a tiny lag at frame 32, the ankle glides a touch too early. Tighten the curve there and the flex will align with the keyframe. Keep an eye on the next few frames; the rhythm has to be flawless.
Okay tightening the curve at frame 32, re-syncing the ankle flex to the keyframe. Watching the next frames now, making sure the rhythm stays within that microsecond window. If anything slips, we’ll tweak the spline and lock it in.
Nice tweak, the ankle now lines up better, but it still nudges a hair before frame 45. Tighten that spline a bit more—remember, every microsecond counts.
