Good to know
Billing
Runs bill your account credits at provider cost with 0% markup. The submit response includes the credit estimate; failed generations are refunded automatically. Add ?dryRun=1 to get the estimate without running anything.
Errors
Errors are always { "error": { "code", "message" } } with stable codes: unauthorized, model_not_available, invalid_parameter, insufficient_credits, rate_limited. A failed run is not an HTTP error — poll responses report status: "FAILED" with the reason.
What makes PixVerse v6 Extend different
Any length from 1 to 15 seconds
PixVerse v6 generates whole-second durations from 1 to 15 seconds in a single pass. One-second clips are perfect for cheap prompt testing — a 360p test costs about two cents per second — and 15 seconds is enough for a complete scene. There are no fixed 5s/10s presets to work around.
Synchronized audio as an opt-in add-on
Flip the Generate Audio toggle and v6 produces background music, sound effects and dialogue that match your prompt. Audio is priced as a per-second surcharge — from $0.008/s at 360p and 540p up to $0.02/s at 1080p — so silent drafts stay cheap and you only pay for sound on the clips that need it.
Multi-shot sequences in one generation
The Multi-Shot toggle turns a single prompt into a sequence with scene transitions and dynamic camera changes — cuts, angle switches and camera moves generated in one pass instead of stitching separate clips. Describe the beats in your prompt and let the model handle the editing.
Eight aspect ratios, four resolutions
Output at 16:9, 4:3, 1:1, 3:4, 9:16, 2:3, 3:2 or cinematic 21:9, at 360p, 540p, 720p or 1080p. A practical workflow on a Scenetra board: iterate at 360p ($0.02/s), then switch the resolution select to 1080p ($0.072/s) for the final render — same node, same wiring, and every generation is billed at provider cost with 0% markup.

Frequently asked questions
What is PixVerse v6 Extend?+
A v6 mode that continues an existing video. Upload a clip (MP4 or MOV, up to 30 seconds and 50MB), write a prompt for what happens next, and the model generates 1-15 new seconds that pick up from the source's last frame. On Scenetra it runs as an Extend node you can wire after any video node.
Can I extend videos that weren't made with PixVerse?+
Yes. Any MP4 or MOV up to 30 seconds and 50MB works — output from other AI video models on your Scenetra board, or footage you shot yourself. The extension continues from the last frame of whatever you upload.
How long can the extension be?+
Each Extend generation adds 1 to 15 seconds — the Duration select sets the length of the new extension, not the total. To go longer, chain extends: extend the extended clip again, and repeat.
Can the extension have sound?+
Yes — enable the Generate Audio toggle and v6 generates BGM, sound effects and dialogue for the new seconds, billed as a per-second surcharge on top of the base rate.
