How can I send saved library videos through Snapchat? For pictures I can see the share option to send it through snapchat, but I can't seem to find it for videos.

I want to be able to record a video using the phones default camera app and then send it to a friend on Snapchat. Since the video is likely to be longer than 10 seconds if it would send multiple videos of 10 seconds each that would be ideal.

How can I do this?
Snapchat now has the desired capability of sending videos from the camera roll in 10 second chunks.

Head to Memories by clicking the circle (now “cards” in 2018) on the bottom center of the screen (or swiping up) on the camera screen and then go to camera roll section on top and long press the video you want and press the blue arrow to share it.
