Yes, you replace images of camera and lenses

Few more questions. 1). Can the horizontal images be changed to vertical format? 2). Can I change the music? 3). Does the Regular License allow me to use this as a youtube intro for all my videos or just one?

1 and 2 yes, 3 – you can use single licence if it is series of episodes of, if not then i think it should be individual license, i am not an expert in licensing, you can ask envato support here https://help.author.envato.com/hc/en-us/requests/new
