That assumes you always want a transitional effect (and then, of course, the opacity parameter of InsertImage can be removed). Overlayed=overlay(im(start,end),imagex,x,y,opacity=0) #start opacity at 0ī=FrameEvaluate(overlayed, "OL_opacity_offset=float(current_frame)/"+string(end-start)) Overlayed=overlay(video,imagex,x,y,opacity=opacity) This could be done by applying Animate () to InsertImage - messy, because of the number of parameters it has and slow because the entire function would be 'recompiled' on each frame.Ī better approach might be to use the conditional variables feature of Overlay (). Opacity can be changed from 0 to 1 as a transition image? Imagex = Defined(filter) ? eval(filter) : last However, it doesn't work when no filter is provided because eval is given an undefined argument, that's why the eval has to be inside the Defined(filter) conditional. In your solution, last gets set implicitly (on the 2nd line). You missed out the other line of my solution - you need to set last so that "filter" has something to work on. But, for some reason, when I don't specify a filter in the script that calls insertimage(), it says that I have "invalid arguments" Imagex = Defined(filter) ? filtered : nverttoyv12()īecause every other use of eval failed and it was the only way that made it work. ![]() I added "string filter" to the parameters, but there is no function named "isDefined", so I used imagex = Defined(filter) ? Eval(filter) : imagexįor some reason, it didn't work, so I split it like this :imagey = imagesource(image,fps=amerate).crop(left,top,-right,-bottom).spline36resize(resizex,resizey) avsi and put in in the "plugins" folder of Avisynth. Single filter = "yourfilter(parameters of this filter)" Multiple filters = "yourfilter(parameters).yourotherfilter(parameters).yourotherfilter(parameters)" (you can add as many as you want, simply separate them with a. Y = Location of your image on the vertical axisįilter = User-defined filter to be applied on the image only. X = Location of your image on the horizontal axis Opacity = Opacity of your image 0.5 means the video and the image will have the same opacity (50% opacity),1.0 (or 1) means your image will completely replace the original image (100% opacity), etc. ResizeY = Your image will appear with this height ![]() ResizeX = Your image will appear with this width Right = # of pixels to crop on the right side of the imageīottom = # of pixels to crop at the bottom of the image Top = # of pixels to crop at the top of the image Left = # of pixels to crop on the left side of the image Start = Your image will appear at this frameĮnd = Last frame on which your image will appear Image = Path of the image you want to add So, I created this simple script and I thought that I could post it here to help anyone that would need to do something similar. As I was doing an amateur movie for a school project, I came across the following problem: I wanted to add a still image with a given size, location, lenght and opacity, but the only functions I found for avisynth were to remove such images (logo removal.).
