Limiting Video File Size?

Hi @alillie! Welcome to the ODK forums. Please introduce yourself here. I'd also encourage you to add a real picture as your avatar because it helps build community!

There currently isn't a way to limit file size on the mobile side. What version of ODK Aggregate are you running? Is it on App Engine (has an appspot.com URL) or on some other platform? Is there a specific error message when the submissions fail?
