java - Crop a Video file with diverse Aspect ratio

Question

I'm trying to give my users the possibility to crop their video in diverse aspect ratio before uploading them on my fireplace database. I'm using an Android-VideoCropView for display the video editor layout for my users and SimpleVideoEditor to crop the video.However, I'm having a hard time to merge both library together when I'm trying to get the info from the VideoCropView and then crop the file with the SimpleVideoEditor this is the result I should have and this is the result I got. So my question is what I'm doing bad and how can I fix that?

Here is my Code

     Uri fileUri = Uri.fromFile(new File(stringvideofile));
                                        String destPath = getVideoFilePath();


                                        //1.
                                        float baseWidthPx =  mVideoCropView.getVideoWidth();    // should be +// todo: match every views one side , then set that side. need an if-else
                                        float  baseHeightPx = mVideoCropView.getVideoHeight() ;
                                        // 2. get the center of crop quad
                                        float  cropQuadCenterX, cropQuadCenterY;
                                        cropQuadCenterX = mVideoCropView.getRealPositionX() + baseWidthPx/2;
                                        cropQuadCenterY = mVideoCropView.getRealPositionY() + baseHeightPx/2;

                                        // 3. get video frame quad center
                                        float  videoQuadCenterX, videoQuadCenterY;
                                        videoQuadCenterX =  mVideoCropView.getWidth()/2;
                                        videoQuadCenterY = mVideoCropView.getHeight()/2;

                                        float dx = videoQuadCenterX - cropQuadCenterX;
                                        float dy = videoQuadCenterY - cropQuadCenterY;

                                        dx = 2*dx/baseWidthPx;  // idk why multiply with 2 :/ divide with baseSizePx to get ratio, that makes sense but why 2???
                                        dy = 2*dy/baseHeightPx;

                                        float translateX = dx, translateY = dy;

                                        FillModeCustomItem fillModeCustomItem = new FillModeCustomItem(
