Kling 2.1 video generation in Standard, Pro and Master

Three entries share one control set: Master generates from a description or one picture, while Pro and Standard animate one picture. Every entry offers 5 or 10 seconds, a negative prompt and a strength control.

Controls and specifications

Kling 2.1 appears as three separate entries. Master is listed in the text and the image workspace; Pro and Standard are listed in the image workspace only. All three take 5 or 10 seconds, carry a description cap of 5000 characters, a negative prompt capped at 500 characters and a strength control from 0 to 1, and none of them offers a resolution setting.

Two differences are visible before you generate. A closing frame can be added on Pro alone, next to the starting picture; Master and Standard take one picture. And each entry is quoted on its own, so the same length carries a different figure on Standard, Pro and Master.

Choose 5 or 10 seconds on any of the three entries. Text mode offers 16:9, 9:16 or 1:1; the image entries have no shape selector. Descriptions are capped at 5000 characters, negative prompts at 500, and the strength field runs from 0 to 1. There is no resolution setting and no sound switch.

What this model is good at

A steer for the details you do not want

Every entry takes a negative prompt of up to 500 characters. Use it for recurring artefacts such as stray text or unwanted hands, and save the wording with the brief so the next task starts from the same place.

A strength control on every entry

The strength field runs from 0 to 1 and is optional. Lower values leave the model more room, higher values hold the result closer to the description, and an empty field sends the default behaviour.

One control set across three entries

All three entries offer the same lengths, description limit and negative-prompt limit. Only Master supports text-to-video and its aspect-ratio selector; Pro alone adds a closing frame. Check each entry’s quote before generating.

Typical projects

Iterate at the lowest figure

Draft the motion on Standard, keep the description and the length fixed while you compare takes, and move the brief to another entry only once the wording is settled.

Land on a known end state

On Pro, provide a starting picture and an optional closing picture to guide the transition. Describe the motion and inspect the generated ending; an exact match to the closing picture is not guaranteed.

Let one shot carry the idea

When a single clip has to carry the whole idea, use Master in the text workspace: write the shot, pick the length, and read the figure before you confirm.

Limits to know before you start

  • None of the three entries offers a resolution setting, so there is no tier to compare. Prepare the source picture at the size you need and check the delivered file before publishing.
  • A closing frame belongs to Pro alone. Master and Standard animate one starting picture and nothing else, and no entry takes a second start frame, a reference set or named subject or voice material.
  • Pro and Standard are image entries, and a description left empty there is sent as a short instruction asking for natural motion. Only Master generates from a description alone, so a text-only brief has to go through the Master entry.
  • There is no sound on or off switch. Audio is not a setting you can influence here; check the delivered file and mute it in your editor when you need silence.
  • The three entries are quoted separately, and at the same length Master sits above Pro, which sits above Standard. Read the figure in the workspace for the entry and the length you have set before you confirm.

How to start

1

Open the workspace

Use a button on this page. It opens the right workspace with this model already selected, in the language you are reading now.

2

Describe the result

Write what should happen in the shot or image. Concrete subjects, framing and action give the model more to work with than short labels.

3

Set the controls and confirm

Choose length or quality tier, shape and sound where offered, then read the credit quote for those exact settings before you generate.

What it costs

Generation uses account credits. Cost depends on the model, quality and output size or duration. Reference images, video or audio may add charges in some modes. Check the workspace quote for your selected inputs and settings before generating; the pricing page lists credit packages.

Questions about this model

Are Standard, Pro and Master the same product?

No. They are three entries with the same lengths and controls but different figures, and a closing frame exists only on Pro. Master is also the only entry that generates from a description alone.

Which entry should I start with?

Choose Standard for an initial image animation, Pro when you want a closing picture as guidance, or Master for text-to-video. Check the output before relying on a particular composition.

How long can the clip be?

5 or 10 seconds on every entry. Those are the only two lengths, so plan the shot around one of them.

What does the strength field do?

It is an optional value from 0 to 1 that shapes how closely the result follows the description. Lower values leave the model more room, higher values hold it closer, and an empty field sends the default behaviour.

Can I set the shape of the video?

In the text workspace: 16:9, 9:16 or 1:1. The image entries have no shape selector, so use a suitably composed source and check the framing in the result.

What does a task cost?

The figure depends on the entry and the length, and it is quoted per task rather than per second. The workspace shows the amount for your exact settings before you confirm.
