Grok Video Generation Guide
Step-by-step tutorial for generating video clips on Flixly using Veo 3.1, Kling 3.0 and Seedance 2.0. Covers prompt setup, model selection, credit costs and export settings.
TL;DR
Grok video generation on Flixly means running text or image prompts through Veo 3.1, Kling 3.0 or Seedance 2.0 to produce 4-8 second MP4 clips. Choose the model on the Text to Video page, set duration and resolution, then generate. Credit cost starts at 12 per 5-second clip.
What Grok video generation means on Flixly
Grok video generation refers to turning text or image prompts into short clips using frontier models inside the Flixly dashboard. It does not include real-time streaming or live avatar chat.
How the pipeline runs under the hood
Flixly routes each request to one of several 2026 models. Text prompts first pass through a diffusion prior that extracts motion tokens, then feed into the selected video model. Seedance 2.0 handles 5-second 720p clips at 24 fps. Veo 3.1 extends to 8 seconds with native 1080p output. Kling 3.0 adds camera control parameters such as pan speed in degrees per second.
Users select the model at generation time. Credit cost is listed on the tool page: 12 credits for a 5-second Seedance clip, 18 credits for Veo 3.1 at 1080p.
Concrete inputs and outputs
A typical text-to-video job takes a 120-character prompt plus optional negative prompt. Output is an MP4 file, 1280x720, 24 fps, H.264, 8-12 MB for a 5-second clip. Image-to-video accepts a single PNG or JPG up to 2048 pixels on the long edge and produces a 4-second motion sequence.
Reference-to-video accepts up to four reference frames plus a motion strength slider from 0.2 to 1.0. Lip sync accepts an MP3 or WAV file 3-30 seconds long and matches mouth shapes to the supplied audio.
Real workflows that use these tools
Creators start with Text to Video to block out a 5-second scene. They then move the clip into Image to Video for follow-up shots using the last frame as reference. For dialogue scenes they route the same clip through Lip Sync Video with a 16 kHz voice track.
Product teams generate 15-second product demos by chaining Motion Poster for static-to-moving transitions and Shorts Generator for vertical 9:16 crops. Each step logs the model name and seed so teams can reproduce results.
Step-by-step first video
- Go to the dashboard and open the Text to Video tool.
- Paste a prompt under 200 characters that names subject, action, and camera move.
- Choose Veo 3.1 from the model dropdown.
- Set duration to 5 seconds and resolution to 720p.
- Add a negative prompt listing unwanted artifacts such as blur or text.
- Enter 4 as the seed for reproducibility.
- Click generate and wait for the 12-credit deduction.
- Download the MP4 and review frame by frame before the next iteration.
Model comparison table
| Model | Max duration | Native resolution | Camera control | Credit cost (5 s) | \ Best for |
|---|---|---|---|---|---|
| Seedance 2.0 | 5 s | 720p | Basic | 12 | Quick storyboards |
| Veo 3.1 | 8 s | 1080p | Advanced | 18 | Cinematic shots |

Where to start
Open the Text to Video page, pick Veo 3.1, and run your first 5-second prompt. That single generation teaches the input fields and credit flow faster than any written description.
