Which model should I use?

4K / Broadcast
Kling 3.0

Native 4K at 60fps with precise camera control. The production powerhouse. If the output needs to hold up on a big screen, start here.

Max Creative Control
Seedance 2.0

Industry-leading physics realism, audio references, and multi-modal input. No other model lets you guide generation from this many angles at once. Best-in-class motion quality.

Character Consistency
PixVerse C1

Named references with subject/background typing give you the most control over character consistency. Fast, cheap, and the R2V quality rivals models at 3× the price. The underrated pick.

High-Res / Open Source
LTX 2.3

4K output, FPS control (24–50), native audio, and Apache 2.0 licensed. Self-hostable for zero recurring cost. The best open-source video model available.

Fast Turnaround
Grok Imagine

Fastest generation times in the field (~30s). Seven aspect ratios cover every platform. 720p cap limits broadcast use, but for social content and rapid prototyping, nothing ships faster.

Official Google API
Veo 3.1

The most accessible major-lab model via official API. Native 4K capability, start+end frame support, and solid all-around quality. The safe corporate choice.
