I am about to go on a vacation, and I recently bought a Canon HF S10 camera. I love the features, but I am having a hard time determining which frame rate format I should use. I also own a Canon HV20 (which my dad will use for the trip), and I have always shot in 1080/60i. However, after hearing that 1080/30p is a better frame rate, I am tempted to use it. My dad may decide to use my footage. Without regards to frame rate mixing, should I use 60i or 30p? Which one is the better format for vacation video?
