Animate an object in unity using a video sequencee

Hi, please I need your help
I took some real world videos and of a person using some tools in an assembly task. and I am trying to recreate the scene in a virtual environment ( Unity)
for the human, it is all good because i used some body motion tracking tools but for the tools I am stuck, how can I create animations from my objects in unity using videos.
Thank you in advance!

Hi @Sarah_orb,

Thank you for your question! It seems, however, that it is not related to SpeedTree (which you marked it as!). You might want to tag your question with the Unity Engine topic instead.
