Thumbnails, floor plans, and continuity
Two cheap documents that prevent expensive redrawing - and the discipline that keeps a sequence from falling apart.

The cheapest place to be wrong is a thumbnail. The most expensive place to be wrong is frame 40 of a finished colour board on a Thursday.
Thumbnail first, always
Before any frame, plan the shot with loose shapes and lines and build the visual narrative frame to frame. Rough, small, fast.
Then - and this is the professional move most people skip - SEND the thumbnails to the client before you begin the sequence.
If you have understood the vision, they will come back with no changes to the visuals. If they come back with changes, you have just saved yourself days. Changes at the thumbnail stage are not a failure. They are the entire reason thumbnails exist.
The overhead floor plan
Draw the location from directly above, like a bird. Mark where the cast move to and from. Mark where the cameras are, and which way they point.
Then go back to visualising the scene, using the plan to imagine the action through the lens: what would the audience actually SEE from that camera?
Then ask the question that turns frames into a sequence: how is the camera moving in relation to the scene, and how does that carry from one shot to the next - does it cut, or does it continue?
This is also the single fastest way to find your 180-degree line (Day 13). It is drawn on the plan, in front of you.
Continuity, which is mostly discipline
- Draw the cast with enough difference that they can be told apart - glasses, hair colour, face shape - and no more detail than that.
- Ask the director how the scene is affecting the cast in these moments, and put THAT into the frame.
- Watch weather and lighting: they change composition and tone. If the light source is not obvious, ask. If it does not matter, ask whether it matters.
- When updating after a review, hold the FIRST direction in mind as well as the new one. If the new direction contradicts the old, do not silently pick one - clarify it, then move forward on a single clear path.
- Work in batches. You will not board a feature in one pass, and trying is how wires get crossed.
“Share previsual thumbnails with your clients before beginning sequences - they should get back to you with no amendments to the visuals if you have correctly produced the vision.”
- Mitchell James Hughes, Storyboard Art
Plan it from above
Build the two documents that protect you, then draw the sequence they produce.
- Take your Day 14 scene. Draw the location as an overhead floor plan: walls, doors, furniture, and the path each character walks.
- Mark every camera position as a numbered triangle showing what it points at. Now draw the 180 line between your two principals.
- Thumbnail the whole sequence at postage-stamp size. Twelve thumbnails on one page. Ten minutes, total.
- Send that page to someone. Ask them to describe the story back to you from the thumbnails alone, with no script.
- Every point where their version diverges from yours is a frame that would have come back for amends. Fix those in the thumbnails - where it costs you two minutes instead of two hours.
What you should have at the end
One floor plan with camera positions and the 180 line, one page of thumbnails, and a list of the frames a stranger misread. You have just run your first client review, for free, before doing any of the work.
Day 16 in one line
Thumbnail, plan from above, and get the changes at postage-stamp size. A change costs minutes in a thumbnail and days in a finished board.
