Ok, i may not have enough time, but i will give my best. Thanks for answer!
Ohh, one more thing:
My entry might have two very different type of wheels (tires) for different terrains.
Can I use one type of wheels in one part of the video, and then remove them,and put another type and continue filming?
Will it be ok since i would remove old and install new parts (just tires). Model will be the same, i would just change the tires.
