Why use it on Smaltino

  • 01

    Private source

    Your uploaded video is checked before a temporary source link is passed to the provider.

  • 02

    Added seconds

    Choose 1–15 new seconds. Credits depend on new duration, quality and audio, not source duration.

  • 03

    Quality and audio

    Choose 360p, 540p, 720p or 1080p, with optional generated audio.

  • 04

    Quote before generating

    A verified quote appears after upload. Changing settings recalculates it; failed runs return their credits.

Models you can choose

Pick a model in the generator above. Each one has its own page with parameters and pricing.

How it works

  1. Upload a video and describe what happens next

    Upload MP4, MOV or MKV, up to 50 MB and 60 source seconds. Describe the continuation, then choose 1–15 added seconds, quality and optional audio. Compatibility can vary by source.

  2. Pick a model and settings

    Choose a model and adjust its settings. The credit cost is shown before you run.

  3. Generate and download

    Run it, then download the result or find it in your creations when it is ready.

Workflows this tool can help with

  • Editors continuing an existing shot

    Upload a short source clip and describe the next action. Set the added seconds, then check the join and motion in the delivered continuation.

  • Teams trying an alternative ending

    Start from a clip you can use, choose quality and optional audio, and review the quote. Compare the continuation with your original before adding it to the edit.

Frequently asked questions

Which videos can I upload?

MP4, MOV or MKV up to 50 MB and 60 source seconds. The provider may reject unsupported source encodings or content. We have not verified every source format.

Will the continuation preserve every detail?

Continuation is generative and may change motion, appearance or sound. Review the result before publishing; there is no guaranteed visual match.

Which settings can I change for a video extension?

The current PixVerse V6 Extend form offers 1–15 added seconds in whole seconds, quality and an audio switch. Changing them requires a new quote before submission. A successful upload or quote does not guarantee the provider can extend every source clip.

Which AI models are available?

This tool runs on PixVerse V6 Extend.

How many credits does one run cost?

Only newly added seconds are billed. Without audio, 360p/540p/720p/1080p cost 4/6/8/16 credits per added second; with audio, 6/8/10/20. The default is 720p without audio. Confirm the verified quote before generating; the source clip's length is not billed as added seconds.

Am I charged if a generation fails?

Requests rejected before task admission are not charged. When a task finally fails, the system releases reserved credits against its original debit record. Check the task and credit records for the settled balance. A status-query error alone is not a final task failure; task credit releases are not payment or subscription cash refunds.

Where can I check progress and see the delivered result?

After submission, the page shows processing, completion, content blocking or failure. If the status lookup fails, retry the status query; that does not mean the task itself failed. A successful task with an asset link shows an image or an audio/video player and a download link below. You can switch between multiple delivered outputs when present. If completion has no preview, check My Creations. No fixed completion time or percentage is promised.

Do changing settings or viewing results start another generation?

No. Reading FAQs, changing inputs or settings, and viewing, playing or downloading existing outputs do not submit a generation. Uploading and checking a quote are preparation steps. Review the selected model, inputs and current credit cost, then click Generate to submit. Clicking Generate again is a new request with its own cost; retries of a status query only check the existing task.

Ready to create?

Pay only for what you generate. Failed or blocked runs return their credits.
