Is it normal for a rear landing gear to be off the ground before the front gear?

The front ( nose ) gear was well off the runway way before either of the main gear left the tarmac . The starboard main gear was off slightly before the port side main gear , but that’s not unusual .

Based on the flight time I expect that it is a CAF.
