As a retoucher, I'm always fascinated by the world of video and how retouching is done in beauty commercials. Foton Inc. released a video a few months ago showing how to make someone look younger with their “Age Reduction FX” technique. Now, here's another video showing how retouching in video is done in 4k format for a typical beauty video.
Whether this is now an industry standard, I am not sure. There are also probably other methods of retouching video too. This is probably the cleanest way out there. However, this does give a great in depth look at retouching video without retouching each frame individually. Apparently, after a standard retouch is achieved, it appears that the results are tracked over the face as the subject moves. This allows for a clean and consistent look without blurring the skin at all.
We developed special movie retouching techniques that won't damage a detail of material,
and don't use "blur skill" for it that is why you feel more real.
And also we work on 4K data without compressing 4K into HD.
This model already had the natural beauty. However,we could improve it more to perform retouching,free transform, and color correction in the movie.
