"put back on the camera for viewing later with your HDMI cable."
If this would work, it would be put back on with the USB cable.
However I'm going to write no. Another member tried and failed. They could get the video out of the camera fine. Just never succeeded in loading it back to the cam.
Can you record in HD and save to a computer without making any changes and then get those files off of the computer and put back on the camera for viewing later with your HDMI cable. Basically keeping all videos on an External hard drive to make room for new videos, But If u really want to watch you can get off of the hard drive of your computer and put back on cameras hard drive to watch?
