Thank you for replying so soon. I have tried with another clip but every time I want to track it using the 3d camera tracker when it says ‘”solving camera” it just crashes my adobe. No error message or anything it just closes as you would if you clicked the x on the top right. The clip is 60fps and 6 seconds long. I have tried making the clip shorter by 2seconds but it just crashes again and the clip is not moving too fast or hard to track. I have done this with many clips before. I cannot try moving the key frames apart by 2 seconds if the clip is not long enough. Thanks.
