60i/60p?
My video camera can shoot AVCHD 60i or 60p, as well as MP4.
I think I understand that the 60i is interlaced, and the 60p means progressive, right?
So, when would I want to shoot 60i and when would I want to shoot a video in 60p?
Thank you.

This depends on the “type” of HD your shooting in ie: resolution. 60i is reserved for 1080 HD. Full hd is 1080p at 30 frames per second, semi-full hd is 1080i at 60 frames per second. The “i” means that frames are interlaced into each other, meaning that in 60i is actually 30 interlaced frames. So if you shoot in 60i you should either use 1080i60 or transcode to 1080p30. In normal AVCHD video there is no 1080p60. Another possibility is that you shoot in 720p and this is usually either in 60p, 24p, or 30p, but hardly ever “i”.
mp4 is MPEG4 a standard in AVCHD camcorders, these camcorders shot video and store them in AVC/h.264 video also known as MPEG4 Part-10 and store audio in ACC also known as MPEG4-Audio. These standards put together are what make AVCHD. They work in tandem to give great video quality and resolution at very low data rates witch gives you small file sizes
If this format gives you trouble with editing, you have a few options:
a. Convert them to an edditing codec (like AIC, DVCPRO HD, HDV, etc.) using a program like MPEG Streamclip or Episode (both work on mac and pc) (least expensive, but slow to convert, fast to edit and encode though)
b. Get an editing program that accepts AVCHD, usauly this is best but it requires a systems powerful enough to handle the decompression process.
c. Capture the video using third-party capture cards. (expensive)
I hope that this rambling helps you. PS. Use Final Cut Pro, Sony Vegas or Adobe Premier.

Sorry me again, forgot to answer your question. You should shoot in 60i when you normal movements, nothing to fast. For sports events, cars, and fast moving objects use 60p.
