That is just one of many procedures to get content from camcorder to a computer.
Some camcorders are not as easy or I have to copy over files, run a conversion. Enjoy what you are doing.
I am looking for a newer camcorder and I keep running into comments about software to upload a flashcard content directly from the camcorder to the computer involving disks and cables and what-not.
I have a late model iMac running Yosemite and I always just pull the card from the (current)camcorder and plug it into the iMac and it opens iMovie and transfers the card contents into iMovie.
Question is: Am I doing something wrong?
