AI video resolution guide — when 480p, 720p and 1080p matter

Resolution is the setting people max out by reflex and then never think about again. It deserves about thirty seconds of thought, because on eroq it is not a slider you can push everywhere — it is a property of the engine you picked. Upscale can take a finished clip to 1080p or 2K, but that is a second pass with its own price, not a free fix. Here is what each engine outputs, and how to decide by where the clip is going to be watched.

What each engine can actually output

Resolution is decided before the prompt is, because it is part of the engine roster. The full grid is on /models; here it is sorted by ceiling.

Above 1080p

• Seedance 2.0: 480p, 720p, 1080p or 4K. Creator plan.
• Veo 3.1 and Veo 3.1 Fast: 720p, 1080p or 4K, with 4K from the Creator plan.
• Hailuo 3: 2K. Creator plan.

Up to 1080p

• Veo 3.1 Lite: 720p or 1080p.
• Wan 3.0 and Grok Imagine: 480p, 720p or 1080p.
• Motion Pro: 720p or 1080p.

768p ceiling

• Motion One: 480p or 768p.
• Hailuo 3 Max: 480p or 768p.

720p ceiling

• Seedance 2.5, Seedance 2.0 Fast and Seedance 2.0 Mini: 480p or 720p.
• Kling 3.0 and 3.0 Pro, Runway Gen-4.5: 720p.

Those ceilings are what the engines render. Motion One and Seedance 2.5 also sell 1080p and 2K tiers: the clip renders at 768p or 720p, then goes through eroq Upscale in the same job, with 2K from the Creator plan.

Two things fall out of that list immediately. First, 1080p no longer means the top plan: Veo 3.1 Lite and Motion Pro render it on every account, Veo 3.1 Fast and Wan 3.0 from Hobby. Second, if a provider refuses your prompt, the engine is one of eroq's own uncensored pair — Motion One at 768p (1080p or 2K through Upscale), or Motion Pro at 1080p. That is not a compromise you negotiate; it is the shape of the roster.

Note also what resolution does change: the price. Video is billed per second at a rate set by the resolution, so a 1080p clip costs more than the same clip at 720p, and 480p costs less. A 5-second Seedance 2.0 Mini clip is 75 credits at its default 480p and more at 720p. The studio shows the price for the resolution you picked before you render, and the grid lives on /pricing.

Resolution is a delivery decision

The right question is never "what is the highest number available". It is "where will this be watched, and what happens to it between here and there".

A 9:16 clip on a phone. This is the most common delivery target and the one that needs 1080p least. A vertical clip on a handset is a small, dense screen held at arm's length, usually watched once, usually while moving. 720p holds up. The things that make a phone clip look cheap are compression artifacts, shaky framing and a subject too small in frame — not the difference between 720 and 1080 lines.

A 16:9 hero on a website. Here the clip is often wider than the viewer's face is from the screen, and it may loop, which means the viewer looks at it more than once. 1080p is the sane default.

A TV, a projector, a trade-show wall. 1080p, without discussion. Anything below it is visible from across the room, and a soft image reads as "AI" faster than almost any other tell.

A clip that will be cropped or reframed in an edit. This is the case people forget. If you are going to punch in, stabilize, or crop a 16:9 render into a 9:16 cutdown, every pixel you did not render is a pixel you cannot crop into. Shoot high, cut down.

A draft, a test, a storyboard beat. The lowest setting the engine offers. You are checking motion and composition, not finish.

Upscale is a finish, not a fix — decide before you render

eroq now upscales. eroq Upscale (coming soon) takes a finished clip, a render or an upload of 1 to 30 seconds and up to 200 MB, to 1080p or 2K (2K from the Creator plan), and keeps its length, frame rate and sound. It is in Video › Edit › Upscale and on the Upscale button of every take, for 9 credits / second of clip at 1080p, billed on five seconds at least. The Editor still trims, cuts, adds looks and exports without adding resolution, and so would Premiere or After Effects.

So a keeper rendered at the draft setting no longer has to be rendered again: upscale it. What Upscale will not do is change the take. It restores detail at the larger size, but the motion, the framing and what is in the shot stay as rendered, and it cannot add what was never there. Two habits follow:

1. Draft cheap, but pin what you liked. The Seedance and Veo engines (and Wan and Runway) honor a reproducibility seed — note it, and your final render at a higher resolution starts from the same place rather than from a new roll of the dice.
2. Decide the delivery target before the first render, not after the good one. An engine that renders the target natively needs no upscale and no second bill. The thirty seconds you spend on that is the cheapest thirty seconds in the whole pipeline.

A worked example

Same clip, two delivery targets, two different setups.

The prompt does not change:

A chef plates a single scallop under a hard overhead lamp, tweezers setting a curl of sorrel beside it, steam lifting slowly through the light while the rest of the kitchen falls away into black. Slow push-in, macro lens, overhead fall lighting, industrial fog palette, calm and precise.

For a vertical short. Hailuo 3 Max, 9:16, 768p, 5 seconds, 170 credits. Hailuo is the engine with a reputation for cinematic physics and dramatic light, which is exactly what "steam lifting through a hard lamp" is asking for, and 768p is its ceiling anyway — a ceiling that costs you nothing on a phone. Side by side with Kling on /compare/kling-vs-hailuo.

For a 16:9 hero on the restaurant's site. Veo 3.1 Fast, 16:9, 1080p, 6 seconds, sound off. Same paragraph, same camera language, a format and a resolution chosen for a screen someone will stare at while deciding where to eat.

Nothing about the writing changed. The delivery target changed, and it picked the engine.

The short version

• A provider refuses the prompt → Motion One (768p, or 1080p and 2K upscaled) or Motion Pro (1080p). Decision made.
• Needs more than 1080p → Hailuo 3 (2K), or Seedance 2.0, Veo 3.1 and Veo 3.1 Fast (4K), on Creator.
• Phone-first vertical → 720p is fine, spend the credits on length or takes instead.
• Website hero, TV, client delivery, or anything you will crop → 1080p: the Veo 3.1 family, Seedance 2.0, Wan 3.0, Grok Imagine or Motion Pro, or a keeper sent through Upscale.
• Drafting → the lowest setting the engine offers, with the seed written down.

FAQ

Which eroq video engines render 1080p?

The Veo 3.1 family, Seedance 2.0, Wan 3.0, Grok Imagine and Motion Pro render 1080p; Seedance 2.0, Veo 3.1 and Veo 3.1 Fast go up to 4K, and Hailuo 3 renders 2K. Veo 3.1 Lite and Motion Pro are on every account; Veo 3.1 Fast and Wan 3.0 from Hobby; the rest, and 4K, from Creator. Motion One and Seedance 2.5 reach 1080p and 2K through Upscale.

Can I upscale an AI video after rendering it?

Yes. eroq Upscale takes any clip of 1 to 30 seconds, a render or an upload, to 1080p or 2K (2K from the Creator plan), with its frame rate and sound kept: Video › Edit › Upscale, or the Upscale button on a take, for 9 credits / second of clip at 1080p. It sharpens the take you have without changing its motion or framing, which is why the delivery target is still worth deciding before the first render.

Is 720p enough for TikTok and Reels?

For most vertical, phone-first clips, yes. Resolution is rarely what makes a short look cheap — framing, motion and compression matter more. Reach for 1080p when the clip will be cropped, reframed or shown on a large screen.

Pick the engine, pick the frame, then write the prompt — open the video studio.
