I made a movie with my Canon camera (IXUS 127 HS model), and unlike other movies, I can't download it to my PC.
The movie is more than 10 minutes long, perhaps that's the trouble.
I use CHDK PTP to transfer files from the camera to the computer.
When I hit download, the download starts, but the file on my PC is zero size, it didn't download properly.
When I view file properties, it says the file size is: -2025752844
Negative file size. This is the root of the problem, I think.
Still, I can view the movie on my camera, it is there.
What can I do to save my movie?
