Give each friend a role in the same story
A duo is more than two people standing together. Give the exchange a point: the planner and the latecomer, the calm teammate and the competitive one, or two friends celebrating a shared win. Use a respectful detail both people recognize and keep the topic focused.
Choose two separate portraits when you want a clear reference for each person. Use the shared-photo mode when you already have a photo with both faces visible. Match the input mode to the photo rather than repeating the same image in two slots. Get permission from everyone pictured.
Pick the stage and the shape of the clip
Choose an available stage that suits the mood. Vertical framing works for phone viewing; a wider frame can give both performers more space. Check the model, duration and resolution together and review the full quote before submission. The current model choices may offer different combinations, so the visible settings are the reference for the request.
Watch both performers through the ending
After the task completes, watch the whole output with sound. Check that the two identities remain distinct, the handoffs make sense and neither face disappears or merges. Listen to the actual words and inspect the last moment before sharing. The generator requests a duet; exact line assignment and word-for-word delivery can vary.
