VSE has only "fade" transition. What if I would like to make a custom one using a black & white video? I tried the "Mask Modifier" but it seems to have a different function. What works for me is the blend:Add or blend:Multiply. I want to add the transition video to the first clip and subtract it from the second clip simultaneously. Of course, it's a drop down menu so I can't choose both. Also, the two clips will affect each other because one is above the other. Both under the transition video.
How it should like: If I managed to do a video about how it should look like, I wouldn't ask this question :) But I'll try to illustrate more here.
How can I use the video to make a transition? My idea that I tried is that I can let the white part display one image and the black part display the other image by adding or subtracting. Here's the video with the black and white: By adding, the black part is replaced with the first image.
So, If I managed to "Add" the video to the first image and "Multiply" it to the second image simultaneously. The two images will replace the two colors (black and white). This way, I can use any transition videos like that and there will be unlimited number of transitions that can be added to blender. Is there an easy way to do it? I'll be dealing with lots of images so I don't want to do many steps each time I do a transition. Thank you,
