How to Use PixVerse v4: Durations, Aspect Ratios and Credit Costs

PixVerse v4 is the fast, effects-forward generation of AISphere’s PixVerse family on VdoBloom: 5 or 8 second clips at 720p or 1080p, from text or from a photo, in five native aspect ratios, starting at 20 credits (about $1.00) for a 720p 5-second render. It is not the family’s highest-quality tier — v5 and v5.5 sit above it — but it is the one you reach for when you need many stylised clips quickly and want the credit cost to stay low enough that a miss does not hurt.

What PixVerse v4 is best at

Two things stand out. The first is the aspect ratio range: 16:9, 9:16, 4:3, 3:4 and 1:1, all rendered natively. Most video models give you widescreen and vertical and expect you to crop for everything else. Native 3:4 and 1:1 matter if you publish to portrait feeds and square placements, because a crop from 9:16 loses the framing the model actually composed.

The second is the effects character. PixVerse built its reputation on punchy, stylised motion — transformations, energy, dramatic camera pushes — rather than on passing for filmed footage. v4 carries that, plus a set of explicit controls most models do not expose: a style preset, a camera movement, and a motion mode. Those are levers you set in the picker rather than things you have to talk the prompt into.

It accepts either a text prompt alone or a starting image plus a motion description, and it carries a MODERATE content label — standard filtering, less strict than the Kling family, without the flexibility of the HOT-labelled models. Rating in the catalogue is 3.8, and the badge on the picker is FAST for a reason.

Real specs and exact credit costs

One credit is $0.05 at the Lite rate of $15 for 300 credits, so the dollar column below is straight arithmetic on the real credit table.

Setting	Credits	Cost at $0.05/credit	What you get
720p, 5 seconds	20	$1.00	The cheapest way to test a concept
1080p, 5 seconds	25	$1.25	Publish-ready short hook
720p, 8 seconds	30	$1.50	Longer beat, draft quality
1080p, 8 seconds	45	$2.25	The full-fat v4 render

Every other spec is fixed: durations are 5 or 8 seconds only, quality is 720p or 1080p, and the five aspect ratios above are the complete list. There is no audio track on v4 — that arrives with v5.5 and v6 in the same family.

For context inside the family, 720p 5-second pricing runs 18 credits on v3.5, 20 on v4, 22 on v4.5, 25 on v5 and 35 on v5.5. The gap widens at the top end: a 1080p 8-second clip is 45 credits on v4, 50 on v4.5, 50 on v5 and 55 on v5.5. That makes v4 the value pick for 5-second work and a slightly awkward one for 1080p 8-second work, where v4.5 and v5 cost 50 credits for visibly better output.

The controls that matter

Three settings shape a v4 clip more than most of your prompt wording does.

• Style. Six options: none, anime, 3D animation, clay, comic and cyberpunk. Setting one of these is far more reliable than writing “in anime style” into the prompt, and it does not consume prompt budget.
• Camera movement. Over twenty presets, including zoom in and out, smooth and quick variants, pan left and right, lateral and vertical moves, crane up, camera rotation, Hitchcock dolly zoom, super dolly out, whip pan, robo arm, follow left and right, and fixed background. Picking one gives you a far cleaner move than describing it in words.
• Motion mode. Normal or fast. Fast compresses the action into the same duration, which reads as energy on a dance or transformation clip and reads as chaos on a slow scene.

How to prompt PixVerse v4 well

Because the camera and style are set outside the prompt, the prompt should carry the subject and the action, nothing else. Five habits that pay off:

• Lead with the subject, then the single action. One clear movement across 5 seconds beats three chained ones, which the model will compress into mush.
• Do not describe the camera in words if you have already picked a camera movement preset. Two sources of camera direction fight each other.
• Say what stays fixed on image-to-video runs: identity, clothing, lighting and background. Drift on those is the most common complaint with any photo-animation model.
• Draft at 720p, 5 seconds. At 20 credits you can test four prompt variants for the price of two 1080p 8-second finals.
• Match duration to the beat. If the idea resolves in three seconds, 5 seconds is the right container; 8 seconds will pad it with invented motion.

A worked example

Goal: a vertical hook clip of a product held up and revealed, for a short-form ad.

1. Start in the video creation workspace and select PixVerse under the model picker, then the v4 variant.
2. Upload the still. Set aspect ratio 9:16, quality 720p, duration 5 seconds — 20 credits for the draft.
3. Style: none, because the product should read as real. Camera movement: smooth zoom in. Motion mode: normal.
4. Prompt: The subject lifts the bottle slightly toward camera and turns it a quarter rotation so the label faces front. Keep the hand, clothing, lighting and background exactly as in the photo.
5. Review. If the move is right and only the finish is soft, re-run the identical setup at 1080p, 5 seconds — 25 credits.

Total for a draft plus a publishable final: 45 credits, or $2.25. The 10 free credits every new account gets with no card will not cover a full v4 render, so pair the model with the pricing page before you plan a batch; one-time packs start at $2.49 for 75 credits and never expire, and paid plans download watermark-free with commercial rights.

If your clip animates a photo of a real person, you must have that person’s consent before generating or publishing it. Explicit and illegal content stays blocked on every model in the catalogue.

When to pick a different model

Move to PixVerse v4.5 when v4’s output looks rough on detail and you want the same format with cleaner results — it is 2 credits more at 720p 5 seconds. Move to PixVerse v5 for new projects where quality leads: at 1080p 8 seconds it costs 50 credits against v4’s 45, which is a small premium for the family’s best non-audio tier. Move to v5.5 or v6 when you need audio or a clip longer than 8 seconds — v5.5 adds a 10-second option, and v6 goes to 15 seconds with multi-shot storytelling.

Stay on v4 when you are generating in volume, when 5 seconds is genuinely enough, or when you are matching footage already produced on v4 and a version switch would show as a style break mid-series.

Frequently asked questions

How much does a PixVerse v4 video cost?

20 credits for 720p 5 seconds, 25 for 1080p 5 seconds, 30 for 720p 8 seconds and 45 for 1080p 8 seconds. At the Lite rate of $15 for 300 credits that is $1.00 to $2.25 per clip.

What lengths and resolutions does PixVerse v4 support?

Exactly two durations, 5 and 8 seconds, at 720p or 1080p. Longer clips need v5.5 at 10 seconds or v6 at up to 15 seconds.

Which aspect ratios can PixVerse v4 render natively?

Five: 16:9, 9:16, 4:3, 3:4 and 1:1. All are generated natively rather than cropped from a master.

Does PixVerse v4 generate sound?

No. v4 is silent video. Native audio arrives higher in the family, with v5.5 and v6.

Can PixVerse v4 animate a photo I upload?

Yes — it takes either a text prompt alone or a starting image plus a motion description, and both modes share the same durations, resolutions and credit costs.

How strict is the content filter on PixVerse v4?

It carries a MODERATE label: standard filtering, looser than the strictest models in the catalogue, stricter than the flexible tier. Mainstream stylised, fashion and action content generally passes.
