Octavius complains to Maecenas(Octavius' advisor) and Agrippa(Octavius' commanders) about Antony's behaviour. A three shot to establish the different actors, a tracking shot can be used as Octavius can be pacing back and forth to show intensity in his complaint, also a reaction shot can be used during their conversation for the atmosphere.
Octavia is sent as a messenger from Antony but Octavius tells her the truth that Antony does not love her but loves Cleopatra. A two shot, a pull back dolly can be used as well as a wide angle shot to show both characters faces and the distraught and sadness as well.
Octavius welcomes Octavia to stay in Rome and insist on it, and Maecenas consoles her by informing her everyone pities her. A full shot of Octavia and Maecenas would work well to give a view of her body language after hearing those news.
