| Abstract: | As universities are moving to online learning with lecture videos, some lecturers have concerns that their videos can be copied and claimed as the property of someone else. To ensure their videos are protected, lecturers can add watermarks. By watermarking videos, viewers cannot copy the video and claim it as their own. Visible watermarks are watermarks that viewers can see with the naked eye. Although effective, they also taint the video and influence the viewer’s experience. Invisible watermarking using motion vectors can provide the protection while not tainting the original video. Literature on invisible watermarking in video using motion vectors currently exists but gloss over the implementation details and the influence the chosen codec has. Due to this oversight, implementation of these algorithms may seem trivial, while it is not. Due to codec complexity and lack of available tooling. In some cases, using the most modern codec imposes challenges that do not appear when using older codecs. This paper provides a novel overview of the most commonly used codecs and their advancements through time which can be used in future research. It finds challenges and pitfalls in implementation such as lack of tooling and complex codec specifications. Which, in turn, makes the field less approachable. This paper contributes to the approachability of the video watermarking research field by providing novel insights into these challenges and pitfalls, provides recommendations how these can be tackled in future research and which currently available tooling can be used. There is probable use for future research aiming to implement novel algorithms. |
