Downloaded the trial version and it is a good resizer but its not the same, the one in the video you can resize by actually pulling or pushing the Image and the OnOne version works almost like their Genuine Fractal 5 Print Pro, you have to type in width and height and wait for it to resize.
OnOne Genuine Fractal 5 Print Pro works excellent (I Own it).
OnOne Liquid Resize works good too, BUT I wish I can get my hands on a copy of the one in the video.
