Ad variant counts should follow the questions you want to investigate. A low unit price has little value if the files cannot be used or do not differ meaningfully.
Define a variant before counting
A new concept may address another purchase motivation. A variant may change the opening, product angle or ending. A new format primarily adapts the work to a placement. All three can require work, but they do not provide the same learning opportunity.
Describe delivery on separate lines: concepts, variants per concept and formats. Do not let a combined total conceal that most files are crops of the same ad. Those crops can be a legitimate requirement; describe them accurately.
A hypothetical production example
Imagine selling a travel bag and investigating two motivations: keeping contents organised and easy transport. Ordering three openings for each produces six content variants, assuming the remainder of each story stays the same.
Exporting those six in two formats creates twelve files, but still only six content variants. This illustrates counting, not a recommended ad volume. The campaign owner should decide how much is relevant to test.
Connect every video to a use
List product, concept, variant, language, placement and planned use. Mark files needing further evidence or local approval. This reveals when many videos depend on the same unresolved product claim.
Leave room for follow-up. Spending the month's entire capacity on the first idea may leave no scope for a useful version after initial observations. Agree priorities with the producer instead of assuming every new request can be added without consequences.
