After Effects expressions for camera shake – how to make it feel organic?

Great question! For organic camera shake, the key is to layer multiple frequencies and use a 'smooth' noise instead of pure random. I use a combination of two nulls:

1. **Main shake null** – Add this expression to Position:
```
freq = 2;
amp = 10;
seed = 123;
t = time;
wiggle(freq, amp, 1, 0.5, t) - wiggle(freq, amp, 1, 0.5, t-0.1);
```
This creates a smooth, continuous drift by subtracting a slightly delayed wiggle. Adjust freq (lower = more subtle) and amp (lower = less movement).

2. **Secondary null** – Parented to the main null, with a faster wiggle for micro-jitter:
```
wiggle(15, 3);
```
This adds high-frequency micro-shake that sells the handheld feel.

For rotation, use a similar expression but with lower amplitude (e.g., `wiggle(2, 0.5)`).

To make it feel responsive to action, you can keyframe the amplitude and frequency using a slider control. For example, during a punch or impact, bump the amplitude up to 20 and frequency to 4, then ease back down. Also, sync to music by using the audio amplitude to drive the wiggle – there are tutorials on that, but a simple approach is to precompose your audio, convert to keyframes, and then use that to multiply the amplitude.

Finally, always apply the shake to a null that your camera is parented to, and make sure to enable motion blur on the null for the best result. Hope this helps!

Thanks for the detailed breakdown! I tried the delayed wiggle trick and it already feels way more organic. I also added a subtle rotation wiggle and it's looking great.

I also found that using the 'smooth()' function on the wiggle output helps if you want an even more controlled drift. For the music sync, I ended up using the Audio Amplitude to drive a slider that controls the amplitude, and it really sells the beat drops.

Appreciate the help – this solved my problem perfectly!
