Resolution is not quality — but it is almost half of how the audience experiences your work. This tutorial covers the four quality tiers, the upscaler, and the discipline of choosing the right one for the right job.
A perfectly composed image at 1024 pixels does not survive a website hero block. A beautifully directed video at 720p falls apart on a 4K screen. Resolution is not the same as quality — a sharp small image will always look better than a blurry big one — but at the moment of delivery, audiences experience low resolution as low quality. The fix is not to default to maximum settings on every shot. The fix is the discipline of picking the right quality tier for the right deliverable, and reaching for the upscaler only when it actually helps.
What This Tutorial Covers
The four generation quality tiers (1K, 2K, 4K, 8K), the upscaler as a dedicated polish step, when to regenerate at higher quality vs. when to upscale a chosen winner, and a cheat sheet of resolution targets for every common fashion deliverable.
These two concepts are often confused, and the confusion is expensive. Generation resolution is the resolution at which the AI builds the image from scratch. Upscaled resolution is the resolution to which an already-generated image is enlarged. They are not interchangeable. A 4K-generated image and a 1K-image-upscaled-to-4K can both be 4K — but they read very differently on a screen.
The rule of thumb: generation resolution determines how much original detail exists in the image. Upscaling enlarges that detail. It cannot create detail that was never there.
The lowest tier. Use it during the exploration phase of any project, for thumbnail comps, for quick concept tests, and for content that will only ever live small (small social variants, email previews, internal moodboards). Cheapest credit cost, fastest turnaround. Do not ship hero work at this tier.
The workhorse tier. Strong enough for most social content, e-commerce listings, email hero blocks, and standard web display. Most of the content you ship in a typical week probably belongs here. Hits the sweet spot of cost and quality.
For the shots that carry the campaign — homepage heroes, paid ad creative, magazine submissions, anything that needs to hold up at large display sizes. The detail at this tier is the kind clients notice without being able to articulate why. Reserve 4K for the chosen heroes, not the whole batch.
The top tier. Necessary for large-format print, outdoor advertising, archival masters that will be re-used at unknown future sizes, and any deliverable where you genuinely need every pixel. Premium credit cost, premium output. Use sparingly and intentionally.
Match Tier to Deliverable, Not to Wish
The temptation to generate everything at 8K "just in case" is the most common mistake at this stage of the workflow. You burn enormous credit budget on detail nobody will ever see — and you produce huge files that slow down your delivery pipeline. Match the tier to where the image is actually going to live.
There is one question that comes up on almost every shoot: I have a great image at 2K and I need it at 4K — should I upscale it or regenerate at 4K? The answer matters because the two approaches produce meaningfully different results.
Upscaling preserves the exact composition and feel of the image you already love — it just enlarges it. Regenerating at higher quality produces a different image entirely; the AI does not perfectly reproduce its previous output, and you may lose the specific magic of the take you wanted. The right choice depends on whether composition or detail matters more.
When Upscaling Is the Right Move
Common Upscaling Mistakes
Upscaling cannot rescue a bad image. If the composition does not work, if the lighting is off, if the proportions are wrong — upscaling makes those problems bigger, not smaller. Upscale only images that are already creatively done. Use the tool as polish, not as repair.
It is tempting to upscale every shot in a campaign so that everything looks "premium". Resist this. The upscaler should be reserved for the small set of images that are actually going to be displayed large — the website hero, the paid ad creative, the print spread. Upscaling everything inflates your file storage, slows down your delivery, and burns credit on detail nobody will see.
For most campaigns, the discipline is to upscale the chosen heroes and ship the rest at their native generation resolution. The audience will not notice. Your credit balance will.
Pick Your Heroes, Upscale Those
Out of every ten images in a campaign, typically only one or two are doing the heavy lifting on hero placements. Identify those at the curation stage. Upscale only those. Move on.
RESOLUTION TARGETS BY DELIVERABLE
──────────────────────────────────────
Social post (square / portrait): 1080 px on long side → generate at 2K
Reels / TikTok / Stories: 1080 × 1920 native → generate at 2K
Email hero block: 1200 × 600 wide → generate at 2K
E-commerce product listing: 2048 px on long side → generate at 2K-4K
Website hero / homepage: 2560 px on long side → generate at 4K
Paid ad creative: 2048 px+ → generate at 4K
Lookbook / printed catalogue: 3000 px on long side → generate at 4K
Large-format print / poster: 4096 px+ → generate at 4K, upscale to 8K
Billboard / outdoor advertising: 8192 px+ → generate at 8K directResolution does not make a bad image good. But low resolution can absolutely make a great image look amateur. The discipline is matching the tier to where the image will actually be seen — not to how much you love it.

Try the Discipline on Your Next Campaign
On your next project, classify every deliverable up front into a tier — 1K, 2K, 4K, or upscaled. Generate accordingly. The combination of credit savings and faster delivery turnaround is one of the most satisfying workflow upgrades the platform offers.
