**2. Conclusion**

There is likely to be a continued need for better compression efficiency, as video content becomes increasingly ubiquitous and places unprecedented pressure on upcoming new applications in the future. At the same time, the challenge of handling ever more diverse content coded in a wide variety of formats makes reconfigurable coding a potentially useful prospect. To summarize it, we presented an overview of H.264 motion estimation and its types and also the various estimation criterion that decides the complexity of the chosen algorithm. We then probed into the available scalability of parallelism in H.264. Finally we focused on an application which is highly sought in the research environment and its advantages in a more elaborate manner.
