This script converts all MTS files in the current directory to MOV files (the MTS originals are kept) trying to minimize any impact on quality and file size. The intermediate files WAV and YUV may become huge (!) but the resulting MOV will be acceptable. The most important parameters are:
-s ...
-sameq
-aspect ...
With these parameter, quality and aspect ratio are adapted from source to destination. You may need to change them for your camera type or recording resolution settings.
