Audio
Footage should not contain any audio unless it enhances the clip, or is considered editorial content.

Mobile device videos
We will accept HD video recorded with a mobile device but please keep the following in mind:

1. When transferring your footage from your phone to your computer please be sure to use the device cable. Emailing/messaging the video as an attachment will result in loss of quality.
2. Please keep in mind that on most phones the user-facing camera has a much lower resolution than the camera facing away from the user. We recommend you to only use the camera with the highest resolution
