Android: How to save video to memory card ONLY

[piechart]

Hello,

I have a Blackberry Priv using the latest Android OS. In the camera settings menu, I selected "save video to memory card". Everytime I take a video it saves it to both my internal memory and the SD card. I was hoping that if I delete the video from my internal memory, the video on my SD card would remain but they both get deleted.

Any idea how I can save my videos to my SD card only?

Thank you

Did you check the video size on both locations?
The file saved on the device memory might be a thumbnail of the video file.
