warpPoints (default empty) – Rect clip series which describes warp transformation source points and max X and Y offsets that will be passed to the warp filter.Negative values – clockwise rotation, positive – counter. angle1 и angle2 (default 0) - range of acceptable rotation angle if overlaid image.Can be specified in any order: aspectRatio1=2.35, aspectRatio2=2.45 is the same as aspectRatio1=2.45, aspectRatio2=2.35. aspectRatio1 and aspectRatio2 - range of acceptable aspect ratio of overlaid image.For example, if source clip is 1440x1080 and overlaid one is 1920x1080 then value will be 1440/1920 = 75%. By default: max value if source image will be completely contain overlay image (pan&scan). minSourceArea - minimum intersection part of source image in percent.For example, if source clip is 1920x1080 and overlaid one is 1920x800 then value will be 800/1080 = 74%. By default: max value if overlay image will be completely contain source image (pan&scan). minOverlayArea - minimum intersection part of overlay image in percent.As soon as acceptable diff value is reached, it will be returned as best align and other configs will not be processed. OverlayEngine then will test each config in given order. It is possible to add some clips to config chain with regular splice operator: Overla圜onfig(…) + Overla圜onfig(…). It is the hack to inject these values to OverlayEngine as independent entity. The filter output is one frame clip that contains given arguments encoded to the image. Configuration contains OverlayEngine settings for auto-align process as well. It defines the bounds of align values such as coordinates of the top left corner of overlaid image relative source image, width and height of scaled overlaid image and its rotation angle.

On the next, a comparison based on the best align settings from the previous stage. For every Overla圜onfig on the first stage all possible combinations are tested in low resolution. To increase performance, auto-align is divided into several stages of scaling and tests of different Overla圜onfigs which particularly include ranges of acceptable align values. The aim of auto-align is to minimize diff value. The result of this function within the plugin is called simply DIFF since during development other functions were tested, too. The function of comparing the areas of two frames is the root-mean-square error (RMSE) on which PSNR is based - but is inversely proportional. The auto-align within OverlayEngine is performed by testing different coordinates (X and Y of the top left corner), resolutions, aspect ratio and rotation angles of the overlay frame in order to find the best combination of these parameters. The plugin is designed for auto-aligned optimal overlay of one video clip onto another. DLL's may be blocked after downloading.Copy all files from x86/圆4 folder to the AviSynth plugins folder.
