Zoom in: 4K and 8K output that survives client scrutiny
A 1080p render is for choosing. A 4K or 8K one is for defending. We took the same frame through both and looked at the five places a client always zooms in.
Every generation comes back at 1080p. That is deliberate: at concept stage you are choosing between directions, and a set of twenty images at 1080p arrives in about 68 seconds while a set of twenty at 8K would be a coffee break and a bill. The upscale is a separate, later decision, and it applies to the two or three frames that survived the shortlist.
The question this article answers is what actually changes when you spend those credits — because “more pixels” is not an argument, and a client leaning into a screen is not looking at the pixel count.
What the numbers mean on a wall
The arithmetic is worth having in your head before the meeting, because it decides the answer more often than taste does. 4K is 3840 pixels across; 8K is 7680. At the 300 dpi a print house asks for, that is a 32 cm image and a 65 cm image respectively. At the 150 dpi a large-format board is happily printed at, it is 65 cm and 1.3 m.
- 1080p — screen shares, a shortlist grid, anything that will be looked at for ten seconds and thrown away.
- 4K — a slide, an A3 board, a project page, a competition panel seen from two metres.
- 8K — a printed spread, a hoarding, a facade study somebody will hold their phone against and photograph a corner of.
The five places a client zooms in
We upscaled the same frame twice and looked at the details that get inspected in practice, in the order they get inspected.
Edges where two materials meet
Brick against concrete, a window reveal, a parapet against sky. This is where a bad enlargement smears, and it is the first thing a builder looks at because it is the detail they will have to make. At 4K the line is clean; at 8K you can read the coursing.
Glass
Glass is the hardest surface in any render because it is doing two jobs at once — reflecting the street and showing the room behind it. At 1080p a soft reflection reads as atmosphere. Enlarged, it either resolves into a reflection of something specific or it reads as fog, and clients notice the difference without being able to name it.
Foliage and ground cover
Planting is thousands of small high-contrast edges, which is the worst case for any enlargement. It is also where the eye goes to check whether an image is a photograph. Hold a tree at 8K and look at whether individual leaves have shape.
People
Faces are the one thing everyone in the room is expert in. At board scale, figures in the middle distance are the safe choice: legible posture, no face large enough to argue with. If somebody has to be in the foreground, look at them at full size before you print, not after.
Text and signage
Any lettering in the scene — a shopfront, a wayfinding sign, a number on a door. Enlargement makes invented text legible enough to read as wrong. If a sign matters, it is a graphic to place, not a detail to enlarge.
What the upscale does not do
It does not change the design, the light or the composition — the frame you approved is the frame you get, larger. It cannot rescue a direction that was wrong at 1080p, and it will not add a detail the model never had. If the entrance canopy is missing, upscaling gives you a bigger picture of a building with no canopy. Go back to the tools that edit a finished image for that, or run again.
- 1080p
- every base render
- 15 cr
- 4K upscale on Basic
- 20 cr
- 8K upscale on Basic
Those are the Basic figures. Upscales get cheaper as the plan grows — 10 and 15 credits on Pro, 5 and 10 on Studio — which is the plan difference that actually matters if you deliver print work every week. The full table is on the pricing page, including what a ten-second video costs on each tier.
The rule that saves the most credits
Choose at 1080p. Deliver at 4K. Print at 8K. Anything else is paying for pixels somebody will look at on a laptop.
Questions we get
- What resolution do renders come back at?
- Every generation returns 1080p images. 4K and 8K are separate upscales you apply to the frames you keep, and they are available from the Basic plan up.
- How many credits does an upscale cost?
- On Basic, 15 credits for 4K and 20 for 8K. On Pro it is 10 and 15, on Studio 5 and 10. The Starter plan does not include upscaling.
- Is 8K worth it for a client presentation?
- Usually not. 4K covers slides, A3 boards and competition panels comfortably. 8K earns its credits when the image is printed large or when somebody will inspect a detail at full size.
- Does upscaling change the image?
- No. The composition, lighting and materials are the ones you approved; the upscale resolves detail that was implied at 1080p. It cannot add anything that was not in the frame.
