Hi

I am trying to give my camera in Houdini a handheld effect and was wondering what the best way would be to go about this.

Normally I would have added noise to a null and linked the camera target to the null but I'm not making any progress in how to translate that to Houdini.

The other option would be to write an expression in the translate parameters of the null and set the camera to look at the null but I am hopeless at expressions.

Any ideas would be great to hear.

Thanks

You can make a camera the child of a NULL. In the Y-AXIS of the Null try this expression.
fit01(rand($T%240),0.2,0.5)
The random generator produces a number in the range of 0-1. The fit function remaps that result to a new range, in this case 0.2-0.5. $T is time modulus 240. Play with the numbers to dial in the effect.

for a little more flexibility (and fun!)
make the camera a child of a null and on the translate parameter RMB and select Motion FX > Noise

Enivob - thanks for your explanation, it really helps to know what each part of the expression means.

Arctor - That's the functionality I was looking for !

I need to test both of these approaches out.

For that type of effect I think its far better to render overscan and apply in comp. Unless its something super specific

When you say overscan do you mean rendering it bigger then crop it in in comp ?

overscan is basically rendering for instance 50 pixels on top of your resolution , outside the camera viewing area. So in post you can shift the image as you have that spare 50 pixels.

Ok thanks Rob.

I am using the apprentice version so I am locked to 720p, I think I will invest in the Indi version soon for the extra res.

Personally I would rather not bake in camera shake so I think I will air on the side of caution especially when the renders are taking so long to get rid of the noise.

Thank you so much goldfarb Motionfx did the trick. Camera Looks handheld using the Alligator Noise.
