I want to get my camera to have a walk animation. How can I do it?
It doesn't have to be complicated; I just want to make it like it's walking.
Make it go from point A to B with some keyframes:
In the Graph Editor, select the Z location track only (press ShiftH to display this track only), and in the N panel, open the Modifier panel, add a Noise modifier, play with the Scale and Strength values (you can enable Restrict Frame Range option if you want the modifier to begin and/or stop at a certain frame):
If you want someting more regular, keyframe a movement on Z location and make it cyclic with a Cycles modifier instead (or press ShiftE to automatically create the modifier):
