You can not put the video back on the internal memory.
You can put the video back on the memory stick.
You need a card reader/writer that can handle the type of memory stick that your camera uses.
These are usually about $20.
Use Windows Explorer to write the video files to the memory stick (through the card reader/writer). Your card reader will appear to Windows to be a new hard disk.
Your camera puts these video files in a specific folder on the memory card. You must put your old video files in that same folder.
Use the original file name. If you have changed the name, it may not work.
Note.....this will work for videos that were created on the S500 camera. If the video came from another source, it may not work.
is there anyway to put video clips back onto the digital camera?
