In this paper I pay attention to video editation issue. Firstly the basic terminology is explained, then the history of analog editation is described and further more even digital editation as well. At this spot, very interesting history of development of this field isn't forgotten and also the architecture of video editing software is described as we know them today. The most used digital forrmats are summarized as well. In next chapters the design of simple video editing application is explained. The applied technologies are briefly described and the decision of the choice is clarified. The result of whole work is a library of tools for video processing applications development demonstrated in a simple application.

Indiana University-Purdue University Indianapolis (IUPUI) / HEVC has achieved significant coding efficiency improvement beyond existing video coding standard by employing many new coding tools. Deblocking Filter, Sample Adaptive Offset and Adaptive Loop Filter for in-loop filtering are currently introduced for the HEVC standardization. However these filters are implemented in spatial domain despite the fact of temporal correlation within video sequences. To reduce the artifacts and better align object boundaries in video , a new algorithm in in-loop filtering is proposed. The proposed algorithm is implemented in HM-11.0 software. This proposed algorithm allows an average bitrate reduction of about 0.7% and improves the PSNR of the decoded frame by 0.05%, 0.30% and 0.35% in luminance and chroma.
