“I am posting this new info here, from another post I made.
Many of you have problem editing this AVCHD codec straight out of your camera. It’s a very difficult codec for the computer to edit and it will JITTER and SPUTTER during the timeline play. Unless you have a super fast computer and editor, this is a problem for most of the people with older systems. So, convert the AVCHD codec into something a bit friendly and your editing will be much better.
There are so many converters and no one has the time to play around with hundreds of them and find the best software for lower cost.
Buy a video converter software and it will convert your AVCHD footage to any format; IE: youtube, vimeo, any iPhones, etc.
All of them works well and some PRIMITIVE editing you can do with either one of them. You can also JOIN the clips together as well in its editor. Your files comes in 2Gb segments and if you drop it in sequence it will be joined.

If you just wish to convert AVCHD to popular editors and to files, check this one out… A,B links do the same but this one is much nicer for this specific purpose.
A note to all members who are interested to convert the hard-to-edit camera footage (AVCHD) to something a bit more friendly to use the above suggested software. There are a thousands of free software similar to that, but I have personally checked out these and looks OK for a playback on your TV or burn a DVD without hassle as in some of the editor. Just drop the file in it and select whatever format you wish. There is more to this, if you have more questions, please ask.
Download a FREE to try from the above links and play around with it. There is a mark on the output video until you buy it.
