A configuration-level comparison of Vidu Q4 and Kling 3.0 on Orelon: reference inputs, native audio, durations, resolutions, credit costs — and which model fits which shot.
Quick answer: Vidu Q4 and Kling 3.0 are both premium AI video models on Orelon, and they are built for different jobs. Vidu Q4 is the reference-heavy one: it casts up to 15 reference photos (plus up to 3 reference audio clips) into a single scene, generates synchronized dialogue and sound effects by default, and renders from 540p up to 4K for any length from 3 to 16 seconds. Kling 3.0 is the established cinematic pick: text-to-video and image-to-video from up to 2 reference images, 3–15 second clips in std, pro or 4K quality. If your shot is "these five characters, saying these lines," pick Vidu Q4; if it is "one striking scene, beautifully moved," Kling 3.0 remains the safer bet.
Last reviewed: October 21, 2026. This comparison is configuration-level: it draws on each model's generation settings as configured on Orelon and on Vidu Q4's provider documentation. We have not run a controlled quality benchmark between the two models, and we do not claim benchmark wins for either side — the differences below are about what each model can take as input and produce as output, not about which looks "better."
What Vidu Q4 brings to the table
Vidu Q4 is Vidu's newest flagship video model, available on Orelon through two endpoints: image-to-video, where one first-frame image sets the shot (the clip inherits the image's aspect ratio), and reference-to-video, which is the feature that sets it apart:
- Up to 15 reference images in one generation. You refer to them by order in the prompt ("the man in reference image 2 turns to the person in reference image 3"), which is how multi-character scenes, product-plus-person shots, and outfit swaps get specified.
- Up to 3 reference audio clips (MP3, 3–12 seconds each) — a voice or a sound the model can attach to a character.
- Synchronized audio by default. Dialogue and sound effects are generated with the video; you can turn audio off for a silent render.
- 3 to 16 seconds, any integer length, at 540p, 720p, 1080p, 2K or 4K. The reference endpoint offers explicit aspect control: 16:9, 9:16, 1:1, 4:3, 3:4.
- Prompts up to 20,000 characters, which is enough to script a full dialogue scene.
The trade-off: Vidu Q4 on Orelon is image-first — there is no text-to-video endpoint, so every generation starts from at least one image you provide.
What Kling 3.0 brings to the table
Kling 3.0 needs little introduction — it is Kuaishou's flagship cinematic model, and the Kling 3.0 generator on Orelon has been one of the platform's most-used premium models. The configuration on Orelon:
- Text-to-video and image-to-video in one model, with up to 2 reference images for the image path.
- 3 to 15 second clips at 16:9, 9:16 or 1:1.
- Three quality tiers — std, pro and 4K — so a std render is a cheap way to check a composition before committing to the 4K run.
- Prompts up to 2,500 characters.
Where Vidu Q4 scales by reference count, Kling 3.0 stays deliberately simple: one or two images, one scene, and a model known for holding physics and camera movement together.

Pricing on Orelon, by example
Vidu Q4 bills per second, so you can price a shot before you write the prompt: a 720p render runs 18 credits per second, which makes a default 5-second clip 90 credits, a 16-second 4K piece 73 credits per second. Kling 3.0 prices by tier and duration — a 5-second pro render is 235 credits. Both show the exact cost above the Generate button before you submit, and failed tasks return their credits under the platform's standard policy. Credits come with the plans on the pricing page.
When Vidu Q4 is the right pick
- Multi-character scenes. Casting several people — or a person, a product and an outfit — into one coherent shot is what the 15-reference endpoint exists for. Nothing else on Orelon takes that many references into a single video task.
- Dialogue you can hear. Generated dialogue and sound effects ship with the clip by default, and reference MP3s let you pin a specific voice to a character.
- 4K deliverables, longer takes. Up to 4K output and up to 16 seconds (in any 1-second step) covers most short-form and ad-creative lengths.
- Tight aspect control on composed scenes. The reference endpoint lets you declare the output aspect instead of following an input image.
When Kling 3.0 is the right pick
- Pure prompt-to-video. With no image at hand, Kling 3.0 generates from text alone — Vidu Q4 on Orelon cannot start from an empty prompt.
- A single hero shot. One image, one camera move, one subject: this is the workflow Kling 3.0 is known for, and the Kling 3.0 guide shows it end to end.
- Cheap composition checks. The std tier exists precisely for trying a scene before paying for the pro or 4K render.
If neither fits
Some jobs want a different shape entirely. For 30-second narrated pieces, Seedance 2.5 on Orelon runs up to 30 seconds with an optional audio track; for short-form speed at lower cost, Kling V3 Turbo and Grok Imagine 1.5 cover the quick-turnaround end. And if the video you have in mind is a meme with a fixed template — a performer swap into an existing clip — the dedicated trend generators like Bulin 47 remove even the prompt work.
Vidu Q4 vs Kling 3.0 FAQ
Does Vidu Q4 support text-to-video?
Not on Orelon today. Every Vidu Q4 generation starts from an image — a single first frame on image-to-video, or one of up to 15 references on reference-to-video. If you need prompt-only generation, Kling 3.0 or Seedance 2.5 both run text-to-video.
Which model generates audio?
Vidu Q4 generates synchronized dialogue and sound effects by default and can be told to stay silent; it also accepts up to 3 reference audio clips. Audio generation is not part of Kling 3.0's setup on Orelon.
Which one renders 4K?
Both. Vidu Q4 offers 4K as a resolution for clips up to 16 seconds; Kling 3.0 offers a 4K quality tier within its 3–15 second range.
Can Vidu Q4 really use 15 images in one video?
Yes — the reference-to-video endpoint accepts 1 to 15 image URLs, and the prompt refers to each by order. Note the practical limit is not the count but the coherence of the cast: clear, consistent reference photos matter more than filling all 15 slots.
What does a 5-second clip cost in credits?
A 720p 5-second Vidu Q4 clip is 90 credits (18 per second). A 5-second Kling 3.0 pro render is 235 credits. Exact prices always show above the Generate button before submission, and failed tasks return their credits.
Can I use both models on Orelon?
Yes — both are premium models, available to paid plans in the video generator. Switch between them from the model picker; the workbench keeps your prompt when the models share the mode you are in.
Which one this week
If you have a scene with named characters and lines to say, that is Vidu Q4's format — start from 720p to check the cast, then step up to 2K or 4K for the final. If you have a single image and want it moved beautifully, Kling 3.0 is still the reference workflow. Both live in the Orelon video generator, one picker away from each other.
