Start with the story beat
Decide what changes because of the conversation. A warning, invitation, reveal or misunderstanding gives the exchange a clear purpose. Remove greetings and filler unless they establish something important.
Place the key line where it can remain visible long enough to read.
Keep profiles and messages consistent
Usernames, profile images, pronouns and tone should match the rest of the fictional project. If the same person appears on a social profile elsewhere, reuse the exact details.
Do not borrow a real person’s account identity or private messages without permission.
Choose static or interactive delivery
A static screen works for an insert shot. Timed incoming messages or a controlled scroll work better when the performer reacts on camera. Test both the screen recording and the physical-device version.
Always remove real notifications and account information before filming.
Write for the audience’s reading speed
The strongest DM scene is short, legible and clearly part of the fictional production—not a claim about a real conversation.
