Grok Imagine Video is the 20-credit fast lane on Picturesque — up to 10 seconds, 7 reference images, and @ImageN prompt syntax. When the clip is right but short or soft, xAI's Extend and Upscale tools finish the job without switching vendors.
Both post tools cost 20 credits each in Edit Studio and require the original generation's task ID — not Grok Imagine Video 1.5 jobs.

Grok Post Tools in One Minute
| Tool | Credits | Job |
|---|
| Grok Imagine Video | 20 | T2V / I2V base clip |
|---|---|---|
| Grok Video Extend | 20 | More seconds, same vibe |
| Grok Video Upscale | 20 | HD delivery pass |
A full generate → extend → upscale chain is 60 credits — still below one Kling 3.0 (60 credits) if Grok's aesthetic matches the brief.
When to Use Extend vs Upscale
Extend when:
- The motion and framing work but the clip ends early
- You need a loop-friendly tail for social
- The preset mode (custom vs preset continuation) fits a storyboard beat
- Duration is final but pixels look mushy at 720p
- You are delivering to a client monitor larger than a phone
- You already extended and only need sharpness
Step-by-Step Workflow
Step 1: Generate on Grok Imagine Video with @Image1 references locked in the prompt — up to 7 stills.
Step 2: Save the task ID from the job card.
Step 3: Open Grok Video Extend, paste the ID, choose preset or custom continuation prompt.
Step 4: Review the seam at the join — Grok's motion prior is snappy; fast camera moves can drift.
Step 5: Run Grok Video Upscale on the final composite if delivery needs HD crispness.
Grok vs Veo Extend (Decision Table)
| Factor | Grok stack | Veo 3.1 stack |
|---|
| Base + extend cost | 20 + 20 | 30 + 30 |
|---|---|---|
| Ref images on base | 7 | 3 on Fast |
| Multi-shot | No | No (use Kling 3) |
| Voice presets | No | Fast tier |
| Best aesthetic | Stylized, meme-native | Cinematic Google look |
Limitations to Be Aware Of
Video 1.5 excluded. Extend/Upscale do not accept Grok Imagine Video 1.5 task IDs — check the model picker before planning post.
No wardrobe edits. Extend continues motion; it is not Kling Omni Edit.
Silent output. Grok base video does not ship native dialogue audio — plan VO in Audio Studio.
Preset surprises. Custom prompts beat vague "continue" instructions on Extend.
