Video (AUV) User Guide

AUV Introduction

The AdUnity AUV is an easy to use web application that allows for quick video cutting and sharing designed to work with both livestream feeds and local files.

The AdUnity AUV allows users to have access to a video library generated from livestream video cuts based on a weekly schedule or even local files that can then be edited and shared. The tool was designed based on the needs of news professionals who wanted to be able to share parts of their live coverages and feeds on the spot without the need for powerful machines with dedicated video editing software and vaste amounts of storage space.

The AdUnity AUV tool uses the HLS protocol for improved speed and ease of use. HLS or HTTP Live Streaming is an HTTP-based media streaming communications protocol implemented by Apple Inc.. It works by breaking the overall stream into a sequence of small HTTP-based file downloads, each download loading one short chunk of an overall potentially unbounded transport stream. As the stream is played, the client may select from a number of different alternate streams containing the same material encoded at a variety of data rates, allowing the streaming session to adapt to the available data rate. At the start of the streaming sessions, HLS downloads an extended M3U playlist containing the metadata for the various sub-streams which are available.

The main purpose of the AdUnity AUVis to facilitate the editing and sharing process of video files from either livestream feeds and/or local files by automating part of the tasks and providing a sleek and easy to use web interface.

Livestream capture

AdUnity AUV can be set to automaticaly save video cuts from an online streaming video source based on a weekly schedule called the Cuts Schedule.

The cuts are automaticaly added the the User's Library and named accordingly to the name their were given in the Cuts Schedule section. A one day example from a Cuts Schedule can be seen in the following image:

Local files can be manually uploaded by the user. The file is added to the User's Library with a Video upload label and it's available for publishing imediatelly. Local file uploads are not available for editing.

In order to appeal to a higher number of devices, only videos converted to the mp4 digital format using the libx264 encoder can be uploaded into the AUV library. The maximum single file size upload is 250Mb.
