Separate statement and framing
A speaker's words and the edit around them create different kinds of emphasis. Note whether a cut, caption, or inserted image changes how a statement is received.
Follow the example
If a work or page is discussed, inspect it independently where available. Ask how much the spoken account explains and what remains visible only in the example.
Keep a precise note
Record the source and location of a statement for your own study. Do not turn a paraphrase into an exact quotation or assume that a short excerpt represents a whole conversation.
