Taxi driver analysis

I am writing a reflection of the scene from the 1976 Martin Scorsese film taxi driver in RMIT building 100.

My tutor Paul has selected this scene from20:06 to 23:30, it is talking about the driver Travis walking into Betsy’s office and interrupt a conversation between Tom and Betsy. Travis tells to Betsy that he wants to volunteer to her and then invites Betsy to have a coffee outside; at the same time Tom is watching them.

These are three Characters ：

Male officer: Tom

Taxi driver: Travis

Female officer: Betsy

These are screenshot to display every single shot.

Outside:

Shot 1: CU camera focus on Travis.

Shot 2: tracking across Travis, long shot, background noise sound effect of closing cab door. The sound of footstep: from close-by to far off.

Inside:

Shot 3: MS; Travis comes into office. The camera is tracking him. Background noise phones ringing people talking sound of the footstep.

Shot 4: Travis’s view, the camera moving towards Tom and Betsy and stops at CU of Betsy. Medium angle.

Shot 5: dirty OTS; MS; low angle, three people in one frame. Then, tom walks away out of frame.

Shot 6: CU

Shot 7: MS; tracking in. Tom is moving out of frame.

Shot 8: OTS CU

Shot 9: MS, Tom is watching a while as background and moving towards Travis and Betsy then walking out of frame.

Shot 10: bird eye looks down of the desk.

Outside:

Shot 11: MS; tracking across, Jazz music.It is very interesting that Tom shows up in the background for three times during the dialogue between Travis and Betsy.

I am wondering how they set up cameras and How many times the actors performing If they shot only one time how they mise-en-scene.

This is my guess about the camera setting.

I did research before I start writing this reflection and shot by shot analysis, I watched this movie online with Chinese subtitle which gives me a better understanding of this film. After that I took screenshots of each shot, then I analyse the scene by using this method.There are several movements of cameras which include tracking in/out tracking across, multiple types of shot like over the shoulder shots, and angled shots like bird eye looks down of the desk. The film editor combines different shots（angles, types, sizes）together to show both sides of a conversation between Travis and Betsy.In terms of clothing, Betsy and Travis all wear red color which is warm. On the contrary, Tom wears cold blue color. It is easy to distinguish two main characters and warm color makes them stand out of the frame.Lines: the lines of Travis shows that Betsy is his love interest.
