I am a beginner filmmaker and have just started to learn editing. I understand how to film a conversation between two people. For example, film the whole scene in a master shot and then film the whole scene with OTS shots for each character. However, I don't understand how you edit the footage once it has been filmed. Do you import the footage to the editing software and then split the footage up every time a character finished their line? Do you open the footage, cut it to the bit you want and then import that same footage again but this time cut it to the next bit? I struggle with editing at the moment and can't find any answers. A detailed step by step answer would be appreciated.
