Introduction
Complete guide to using Kling 2.1 API with Standard and Pro Modes
Kling 2.1 API with Standard and Pro Modes
Kling 2.1 on PoYo gives developers a clear split between an efficient standard path and a more controllable pro path. Both are built for short-form video generation with a required start frame, while pro adds optional end-frame control for tighter visual direction.
Available Kling 2.1 API Models on PoYo
02
kling-2.1/pro
Use pro mode when you need optional end-frame control and are willing to trade higher credits for tighter shot planning.
Key Features of Kling 2.1 API
The main differences developers care about when choosing between standard and pro.
01
Start-frame image-to-video generation
Both Kling 2.1 modes require a start image, which makes the model family a good fit for teams that want the opening composition locked before motion begins.
- start_image_url is required in both modes
- Better control than prompt-only workflows
- Useful for product shots, key visuals, and concept art
02
Standard mode for lower-cost short clips
kling-2.1/standard keeps the workflow simple: start-frame input, 5s or 10s duration, and a lower credit tier for everyday short-form generation.
- Lower cost than pro mode
- 5s and 10s clip lengths
- Good default for repeatable short-form work
03
Pro mode adds end-frame control
kling-2.1/pro adds optional end-frame guidance, which helps when the closing state of the shot matters for reveals, transitions, or tighter storyboard matching.
- end_image_url is available in pro only
- More control over where the shot lands
- Useful for reveals, transitions, and ad planning
