I use a Sony Nex5n to record in 50i. The videos used to be seen on my OSX as mts files, now it is a package called AVCHD.
I move the .mts files out of the package and import them to Premier/FCP/iMovie.
Many times only half of the videos is useful, therefore today I was looking for a software that can do some quick editing, mainly trimming.
Apart from Quick time I couldn't find any, quicktime doesn't play mts, but I can open the AVCHD pack and save the trimmed files separately.
The quick way to do this is buy saving the trimmed file into quicktime movie.
The size of the file is just a bit less than the mts file.
Does this effect the quality of the movies in any way or is it as good as the originals?
