Screen in a phone or browser frame

Give me an edit brief: where it goes on the timeline, the exact settings, and what to check before export, for a short video about [your product], for [your audience]. The technique is screen in a phone or browser frame: the interface reads as a real product on a real device. How it works: the app screen inside a phone frame that slides up into the shot, the screen scrolling inside it. It is right for: app and web product shots in an animated video. Put a real screenshot or a screen recording in the frame; a drawn stand-in is the fallback, never the plan. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing.
