Setting right canted frames

(A) Before setting the spirit level right the image is tilted.

(B) After setting the spirit level right, the image is straight.

Ever wondered why videos shot by beginners tend to have tilted/canted shots? Either they've not used a tripod (by the way, tripods always give you steady shots) or they didn't set right the spirit level on their tripods.

A good tripod will have a spirit level: A bubble encased in glass on the tripod head.
Remember: If the bubble is within the red circle printed on the glass case, you get straight video. If the bubble is outside the red ring, you get tilted video.
Next time you want to shoot straight videos, check the spirit level.
Next time you want to shoot music videos, you may not want to check the spirit level!
