I am trying to set up some basic video slides that have smooth fade transitions so they are seamless, but am having trouble. First, I have four different videos. I created one slide for each video and added the video as a layer in each slide. I am using the crossfade transition for each slide.

The issue I am having is that when previewing, the transition is not smooth at all. For some reason at the end of each video/slide, a white flash happens then a screen shot of the slide again, then it goes to the next slide /video. 

How can I make is so that each slide  simply fades into the next without separation, white screen or image flashing before the transition.

Thanks for the reply. How would I do that? I am only seeing options for a background image or color, not video.

One last question, thanks. If I set them as backgrounds, is there a way to adjust their positions in the frame of the slide for example to make sure the top of the video is visible? Otherwise I have to display the full height/dimension of the video and not really wanting to do that as it makes the slide go "below the fold" on larger resolution screens.

Here is an the display( https://angelbeautyhaus.com/) in question and you can see how the slides flash before going to the next slide. I am actually zooming in on the layers so the faces are more close up on a couple of them. Here is how they are needing to be as backgrounds as you suggested for smoother transitions. https://angelbeautyhaus.com/demo/  as you can see the display has to be much taller to get the portion of the video I need to be seen, but in this version i cannot zoom in more on their faces. In an ideal world I would be bale to get the first option to smooth transition like the second option.
