In your video you are seeing two types of cloud: cumulus, and cirrus.
The cumulus clouds are the low dark "puffy" clouds, that you refer to as "regular". They are probably just around 2,000 to 5,000 feet about
The cirrus clouds are much higher, probably around 30,000 to 40,000 feet. They are made of ice crystals which slowly descend and the difference in
wind speeds at various altitudes makes them streak out like you see.
