MG 1.1 Video upload security error

[Alpha1]

Video upload fails. FFMPEG is running. I am getting a popup 'security error'

Console has this:
AttachmentUploadError: Object { type: "AttachmentUploadError", file: Object, ajaxData: Object, flow: Object, timeStamp: 1486480815355, jQuery111009838495012567646: true, isTrigger: 3, namespace: "", namespace_re: null, result: undefined, 5 meer… }

It's likely the size of the file being uploaded is exceeding the post_max_size value in PHP. post_max_size should be roughly equal to the upload_max_file_size value.
