Today Youtube announced it’s new blurring tool for editing videos online.
It’s biggest purpose is directly censoring parts of video while editing it online. The new tool is located under the Enhancements portion of Creator Studio.
After choosing this option, the Creator Studio will do it’s work and after the user have to review the effect, to ensure the blurred objects stays blurred till the end of the video.
Because this tool has tracking motion option, you can go in the video and move or resize the blurriness of the object so it can be censored right.
Having the ability to do this within YouTube itself will save a great deal of time in more complex editing programs, where many times you have to custom keyframe the blurs or otherwise track the movement.
