Hi @toad78!
YouTube videos aren’t particularly fit for background videos, as when the video starts the YouTube branding overlays are there, and there is no option to remove these. If you want to use a video as a background video, then you will need the Pro version and .mp4 videos, but note that on this forum we can only provide support for the free version, so if you have the Pro or you have questions regarding Pro features, then please contact us through our form:

If you insist on using YouTube videos, then:
A.) Why not upload a video to YouTube where all 3 videos are present already? Then if you select this for the YouTube layer, enable the “Loop” option as well, so the video can replay when it’s done. Like this you would avoid many problems, and the overlays between the videos when they would change.
B.) If you don’t want to upload a video of your own, then you could collect the needed videos into a public playlist, then set the first index of that playlist to be the source in the YouTube layer, this way once the first video is over, the next would play, but this has the above mentioned problems, and probably wouldn’t be able to loop either.
C.) All of this could work with your current setup as well (so the 3 slides which contain the YouTube videos + 1 Static overlay which has the text). In your case the problem is that it you have Autoplay enabled. You do not need this as “When Ended – Go to next slide” will automatically switch to the next slide when the video is over, so you should disable the Autoplay at the Slider Settings > Autoplay tab:

Additionally, the Main animation is probably too long, so possibly that is the cause for the 3 second delay. You could try setting the Main animation to “No animation”:

Like this the other slide would appear instantly (but of course it still takes time for YouTube to start the video, which is something you cannot do anything about)
But again, if you want to achieve the effect of 1 video, then the easiest would be to make 1 video, so solution A.) would be the best and easiest in my opinion.
