My page is asking users to upload their photos and videos, but I want to limit the file size. What is a realistic size limit for short video (under 30 sec) shot on a iphone or android.
The chart below shows the approximate size of a 30 second video on various high end video-capable mobile handsets. (Adapted from Engadget's video showdown here.)
Based on these stats, I'd suggest an upload limit of around 100MB.
