When you’re shopping for a video tripod, it might be tempting to buy the cheapest one you can find, but that’s probably not the best idea. What about if you have access to a really, really nice tripod, but a small, lightweight camera? Is that a good idea?
Fluid head: This is a non-starter if you find a tripod without a fluid head. The movements will be jerky if you do buy one without this type of head.
Appropriate size for the weight of the camera: If your camera is too big for the tripod, you risk failure and breaking the camera. If it’s too small, you’ll never get the tripod balanced right. Make sure you get the right one.
Weight for its use: Buy a light tripod for portable use, but get a heavier one if it will always be in one place.
