Guardrails

For semantic requests such as "720p landscape" or "square video", use
```
--resolution
```
with
```
--aspect-ratio
```
.
Use
```
--size
```
only when the user explicitly requires exact
```
WIDTHxHEIGHT
```
pixels; it overrides and replaces both semantic dimension fields in the request payload.
Validate that
```
--duration
```
is between 3 and 15 seconds.
Validate that
```
--resolution
```
is
```
720p
```
.
Validate that
```
--aspect-ratio
```
is one of
```
16:9
```
,
```
9:16
```
, or
```
1:1
```
.
```
--size
```
is format-checked locally but not matched against a static model allowlist; model/provider compatibility is validated by the API.
Do not pass
```
--seed
```
; Kling Pro does not support deterministic seed.
Frame images and input references may be sent together; OpenRouter gives
```
frameImages
```
precedence and treats the request as image-to-video.
