From my friend's SD card, I transferred our school project's videos and photos to my own SD card, it was successfully copied but when I inserted my memory card back to my Canon DSLR and scanned the files, only the photos can be seen not the videos. Though when I connect the memory card to the computer I can see the videos saved in the SD card.
What can I do? I need to have a copy of the videos, I should be able to watch the videos in my camera.
P.S
If this helps, my friend owns a Nikon and I own a Canon, I transferred the files from her Nikon's memory card to my Canon's.
