Thank u

thanks i didnt know u can change the spline i thought it would mess up track

Hi i understand where you are going with pickwhiping but my master null has only 1/3rd of the position keyframes, 2/3 of the data are in other nulls. so if i dont have complete keyframes how can i pickwhip?
here is a list of what i have in my project right now
1st null. Position and rotation keyframes from frame 1-91
2nd null. position and rotation data from frame 92-201
3rd nul. position and rotation data from 202-499

layer 2 is parented to layer 1

layer 3 is parented to layer 2

therefore Layer 3 is the master null that moves throughout the shot because of parenting but has only 1/3 of the keyframes.

now How would i go about stabilizng the shot using these information?

[Bipop Upreti]

that doesnt stabilize the video, it just moves and rotates the video according to the null data. I need to do the opposite to stabilize and inorder to do that i need the keyframes, but i dont have complette keyframes in my master null becaue they are divided in three nulls with seperate positional data.
do you understand now? its kinda confusing to explain

thanks for that advise and the info on parallax. so according to what i understand about parallax, in a shot wheere i want to replace somethinng in the background should i track something in the background or would the track of any point work? for ex. in a shot like this picture where my camera is shaking like a hand held

if i wanted to replace something in the back hills should i track something around that part or could i track one of the flowers in foreground and use that track to add elements in the background hill

i dont know why the video didnt convert. but yeah that is how i apply trak data i apply to null and parent it. but do u know why works only on one side of the shot? is it because i tracked the object that is on the right side of the shot? or somehting else is wrong

[Bipop Upreti]

I would track in mocha but i do not know how to import tracking data for sky replacement, as far as i know mocha exports spatil rotation data and AE doesnt import spatial it imports temporal or vice versa
