I'm trying to add a bulldozer shaking super fast for a video i'm editing and i don't know how to make the effect. I tried transform and adjust each frame to move over and over but it just didn't save the changes and didn't work for some reason. Any help is appreciated!
You can do it by keyframing object location and giving it a noise F-curve modifier. I chose my camera to add some shake into it.
Select the object you want to shake. Press i and choose Location to keyframe the object location.
Keep your object selected and go to Graph editor. Shortcut is Shift+F6.
Select the dimension you want to shake your object to. I chose Z but you can do this to all dimensions if you want to. Select Key and under Add F-Curve Modifier you find Noise.
From Modifiers panel you can adjust the strength. If the panel is not visible you can press n key. You can play with other settings if you want to.
Just play the animation and you have some shaking.
In Video editor you can keyframe the offset location of your image or image sequence as can be seen in image below. Everything else is the same.
I would suggest checking out this tutorial by Ian Hubert and use those techniques to either animate the camera or bulldozer.
