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 2.5 and Seedance 1.5 Pro — 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 Seedance 1.5 Pro's audio toggle doubles its per-second rate and the Seedance 2 family generates audio by default.

Cost spread matters just as much. A 480p 4-second Seedance 1.5 Pro clip is 3 credits; the same platform's Seedance 2 at 4K for 15 seconds is 1,240. 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 or 720p. Next longest is Vidu Q3 at 16 seconds (Q3 Turbo is priced for 5 and 8 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 2.5 and Seedance 1.5 Pro; HappyHorse 1.1 offers both 21:9 and 9:21.
  • Cheapest renders: Seedance 1.5 Pro at 480p/4s costs 3 credits, ByteDance V1 Lite Image-to-Video at 480p/5s costs 4 credits, and Seedance 2 Mini at 480p/5s costs 8 credits on its promotional rate, reverting to 19 when the promo ends on 7 September 2026.
  • Most predictable price: Veo 3.1 is flat-rate — 40 credits for Fast and 160 for High Quality, regardless of settings.
  • Camera and style control: PixVerse exposes 5 styles (anime, 3D animation, clay, comic, cyberpunk), 21 named camera moves including Hitchcock dolly-zoom, whip pan and crane up, and normal or fast motion modes.
  • 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 1,240 credits, roughly 413 times a 3-credit Seedance 1.5 Pro 480p draft.
  • Editing rather than generating: 7 video-to-video models (Runway Aleph, Luma Modify, 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, PixVerse v5.5 or V6, Vidu Q3 or Q3 Turbo, or LTX-2 Fast. Sound is also available as a priced option on Kling 3.0 and Kling V2.6, and Seedance 1.5 Pro doubles its per-second rate with audio on, while the Seedance 2 family generates audio by default.

  3. 3.Draft cheap before you commit

    Test composition at 480p on Seedance 1.5 Pro (3 credits at 4s) or ByteDance V1 Lite (4 credits at 5s). At those prices you can iterate a dozen 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 1,240 credits.
