The article is devoted to video analysis - recording and processing of video information about moving. Using video analysis allows to convert video into a source of quantitative data of moving. Comparison of the three software environments, which include video analysis tool, is done. It is shown that the sequence of actions in the video analysis is the same in all programs and includes video recording, scaling procedure, movie marking and mathematical processing of the results.
