How do I restore deteted camera tracls?

By this I mean the Location, X, Y Z

Or rotation Roll Pitch ,Yaw

etx

Ive run into this probklem several tiems before and had to dump the entire set of camer flight movement by erasign the camera competely but want to try and fix it.

It happesn usually if I have accently moved more that one track at the same time and then try and fix it by deletign a kjey frame but accently click and delte the whole camera tack behind whihs schould not happen.

IE I now have a camer with a rotation YAW contol and a Roll control track to add key frames too but no Pitch, the pitch tack has diappeared.

How do I resture things liek this please

Take a look here. You can re-enable them by right clicking in the Track Area and toggling on those channels.
