Thanks for the correction, how can I spot the difference?

@@Damien-zk8vh Cirrocumulus looks like tiny puffs and will be associated with cirrus. They make the so-called 'mackerel sky'. Altocumulus are the fat puffs in your video. A good way to measure is this: arm stretched out overhead, cirrocumulus puffs are the size of your thumb. Altocumulus rolls will be the size of your fist.
