I was grilling on the porch and noticed a round looking cloud and tok a video. Didn't notice the objects until later

I took video of a circular cloud and another one just above it. I shot for a few minutes and stopped to get food off of the grill. Looking at the video later, I noticed an object shooting from left to right at very high speed near the top of shot. Then about 5 seconds later, one shoots from right to left and slightly upward around the middle of the screen. I was able to pause the video enough to get a couple of screen shots. One has an odd shape, but one looks like the proverbial flying saucer. Grey or black in color. Behind was a partly cloudy sky. I was facing North on my porch, looking North, at about 30 degrees from the horizon.
