Nothing wrong there .... but I would advise to remove the lens cap !!
There are two things that will tell you if anythings wrong in props / motors :
1. Sound. Your AC sounds fine ... but if it has out of balance props etc. - you will notice a sound that drops in and out of harmony.
2. Shake or rocking in 3 axis as the Flight Controller has trouble keeping stable ... it will over-react and then act opposite creating a seesaw or shake that is unmistakable.
