How to record a video from a mobile device
On your mobile device simply click the “+” icon down in the right corner and click "New video."
Now you can choose between filming a new video directly from the phone or select the video from your photo library you want to upload.
If you film a video, simply save the video afterwards and wait for it to be uploaded. You can continue this process for all the videos you want to upload or film simultaneously. You do not have to wait for each of the videos to be finished uploading, before you start to upload another video.
