Hey, I am a motion designer I make intros, I have this weird thing that the camera does something like this: https://gyazo.com/7d8614e6dcf8633b696364ae740649b0

And here is another example: https://gyazo.com/7d8614e6dcf8633b696364ae740649b0 the text starts moving before the keyframe, Is there a setting to disable this?

Thanks

First, it looks like you accidentally linked the same file for both examples.

Second, while videos or image files are helpful for assistance with render issues, it's usually best to post your project file so that anyone trying to help can see every detail of your scene. It may just be a case of keyframe interpolation, but without seeing the project file it's hard to tell.

Good points. First looks like gimbal lock. Could probably be fixed by giving the camera an up vector constraint. Second is probably due to spline interpolation.

I changed the interpolation to Linear, https://gyazo.com/18a5f8f2436b15b4fb9880392458a919
That fixed it but I'm still getting a weird problem: https://gyazo.com/5a513deafc97f9945a40e9b81d1f583c, I have keyframed it to rotate to the left not to the right.

In reference to Adam's first observation, have you researched gimbal lock, and how to avoid it? And again, by watching only a video, and without a project file, we can only guess at what you're trying to do.

No, It's not gimbal lock, I did a research on that.. I have deleted the project file but I can create a example of the problem and upload it here.

Ok. I would be interested to see it.
