Which AI Video Model to Use — 14 Families, One Platform

There is no model that is best at everything, so the useful question is which model is best for the shot in front of you. VdoBloom carries all 14 model families in one dashboard — plus Lightricks LTX-2 Fast on the effect tabs — which means the answer can change per clip without changing product.

The hard constraints are what usually decide it. Only ByteDance Seedance 2.5 renders a single take up to 30 seconds. Only Google Gemini Omni, ByteDance Seedance 2, Kling 3.0 and Lightricks LTX-2 Fast reach 4K. A 21:9 cinemascope frame comes from MiniMax H3 Text-to-Video, Seedance 2, Seedance 2 Mini and Seedance 2.5 — and HappyHorse 1.1 adds the vertical 9:21 counterpart. Native audio at no extra cost comes from Wan 2.7, Wan 2.6 Flash, MiniMax H3, SkyReels V4, PixVerse v5.5 and V6, Vidu Q3 and Q3 Turbo, and LTX-2 Fast — and sound is a priced option on Kling 3.0 and Kling V2.6, while the Seedance 2 family generates audio by default.

Cost spread matters just as much. A 480p 4-second Seedance 2 Mini clip is 7 credits; the same platform's Seedance 2 at 4K for 15 seconds is 1,248. Scouting on a cheap model and finishing on an expensive one is the single biggest lever on what a finished video costs you.

What this tool does

  • Longest single clip: ByteDance Seedance 2.5 renders 4 to 30 seconds at 480p, 720p or 1080p. Next longest are Vidu Q3 and Q3 Turbo at 16 seconds, then a group at 15 seconds including Kling 3.0, MiniMax H3, Wan 2.7, SkyReels V4, HappyHorse and PixVerse V6.
  • 4K output: Google Gemini Omni, ByteDance Seedance 2, Kling 3.0 and Lightricks LTX-2 Fast.
  • Widest frame: 21:9 is available on MiniMax H3 Text-to-Video, Seedance 2, Seedance 2 Mini and Seedance 2.5; HappyHorse 1.1 offers both 21:9 and 9:21.
  • Cheapest renders: ByteDance V1 Pro Fast Image-to-Video at 720p/5s costs 7 credits, and Seedance 2 Mini costs 7 credits at 480p/4s and 8 at 480p/5s.
  • Most predictable price: Veo 3.1 is flat-rate — 25 credits for Fast and 100 for High Quality, regardless of settings.
  • Camera and style control: PixVerse exposes 5 styles (anime, 3D animation, clay, comic, cyberpunk) on every variant, plus 21 named camera moves including Hitchcock dolly-zoom, whip pan and crane up, and normal or fast motion modes, on v4 and v4.5.
  • Audio in the same pass: MiniMax H3 renders 4 to 15 seconds at 768P or 2K with audio and supports aspect ratios up to 21:9.
  • Fast, cheap drafting: Pruna P-Video is a real-time model at 8 credits for a 720p 5-second clip; Seedance 2 Mini is the cheapest Seedance tier.
  • Cost ceiling to watch: Seedance 2 at 4K for 15 seconds costs 1,248 credits, roughly 178 times a 7-credit Seedance 2 Mini 480p draft.
  • Editing rather than generating: 5 video-to-video models (Wan 2.6 V2V, Wan 2.7 Video Edit, SkyReels V4 V2V, HappyHorse Video Edit, Gemini Omni V2V) plus Topaz Video Upscale at 1x/2x/4x.

How it works

  1. 1.Start from the constraint, not the model name

    Decide length, resolution and aspect ratio first. Over 16 seconds means Seedance 2.5. 4K means Gemini Omni, Seedance 2, Kling 3.0 or LTX-2 Fast. 21:9 means MiniMax H3 or a Seedance variant.

  2. 2.Decide whether you need audio in the render

    If the clip needs sound generated with the picture at no extra cost, choose from Wan 2.7, Wan 2.6 Flash, MiniMax H3, SkyReels V4, Vidu Q3 or Q3 Turbo, or LTX-2 Fast. PixVerse, Kling 3.0 and Kling V2.6 clips are silent on the dashboard, while the Seedance 2 family generates audio by default.

  3. 3.Draft cheap before you commit

    Test composition on Seedance 2 Mini at 480p (7 credits at 4s) or ByteDance V1 Pro Fast at 720p (7 credits at 5s). At those prices you can iterate several times for less than one premium render.

  4. 4.Render the final on the model that fits

    Move the settled prompt to the model your constraint picked. Check the credit cost in the panel first — resolution is the steepest multiplier on nearly every family.

  5. 5.Upscale instead of over-generating

    Generating at 720p and running Topaz Video Upscale at 2x or 4x is usually cheaper than generating at 4K, especially on Seedance 2 where 4K/15s reaches 1,248 credits.

Frequently asked questions

Which AI video model makes the longest clip?

ByteDance Seedance 2.5, which renders 4 to 30 seconds at 480p, 720p or 1080p. Vidu Q3 reaches 16 seconds, and Kling 3.0, MiniMax H3, Wan 2.7, SkyReels V4, HappyHorse and PixVerse V6 reach 15.

Which models output 4K?

Google Gemini Omni (720p/1080p/4K), ByteDance Seedance 2 (480p through 4K), Kling 3.0 (std/pro/4K) and Lightricks LTX-2 Fast (1080p/1440p/4K).

Which model is cheapest per clip?

On VdoBloom, ByteDance V1 Pro Fast Image-to-Video at 720p for 5 seconds costs 7 credits, and Seedance 2 Mini at 480p costs 7 credits for 4 seconds and 8 for 5 seconds.

Which model should I use for a cinematic 21:9 shot with sound?

MiniMax H3 Text-to-Video: 4 to 15 seconds, 768P or 2K, aspect ratios up to 21:9, with audio rendered in the same pass.

Which model is best for camera movement and stylised effects?

PixVerse v4 or v4.5. They expose 5 styles, 21 named camera moves — including Hitchcock dolly zoom, whip pan, crane up and follow shots — and normal or fast motion modes. Newer PixVerse versions (v5, v5.5, V6) keep the styles but drop the camera moves; V6 adds multi-shot sequences from 1 to 15 seconds.

Is one platform's model roster the same on every plan?

On VdoBloom, yes — no video model is locked to a higher tier. FREE, STARTER, LITE and PRO accounts all see the same 54 variants; the plans differ in how many credits you get.
