How to Generate Video with AI
Step-by-step guide to generar video con ia on Flixly. Compare models like Seedance 2.0 and Kling 3.0, see credit costs, and follow a concrete workflow that produces 8-second clips in minutes.
TL;DR
Pick a model such as Seedance 2.0 or Kling 3.0 in the Flixly dashboard, enter a prompt or reference image, set length and aspect ratio, then generate. One 8-second clip costs around 12 credits and finishes in under a minute.
Flixly lets you generar video con ia by selecting a model such as Seedance 2.0 then entering a prompt or uploading reference images at the dashboard. Users buy credits and generate clips that last 5 to 10 seconds in standard runs.
Choosing the right model for your project
Start by picking from frontier options listed in the dashboard. Seedance 2.0 handles motion consistency at 1080p resolution while Kling 3.0 supports longer 15-second sequences with better physics. Veo 3.1 adds camera controls that let you pan or zoom without extra edits.
Try Text to Video first if you have only a script. Switch to Image to Video when you already own still frames. Reference to Video works when you need character consistency across multiple shots.
Model comparison table
| Model | Max Length | Resolution | Credit Cost | \ Best For |
|---|---|---|---|---|
| Seedance 2.0 | 8 sec | 1080p | 12 | Smooth motion |
| Kling 3.0 | 15 sec | 720p | 18 | Complex scenes |
| Veo 3.1 | 10 sec | 1080p | 15 | Camera moves |
| Wan 2.7 | 6 sec | 480p | 8 | Quick tests |
Step-by-step generation workflow
Open the dashboard and pick your tool. Type a prompt that includes subject, action, and camera direction. Upload a reference image if you want to lock a character look. Set duration and aspect ratio then hit generate. Review the output and use the first-to-last-frame tool to extend a clip by one more second.
First to Last Frame helps when you need to bridge two static images into motion. Video to Video lets you restyle an existing clip with a new art direction without starting over.
Adding audio and finishing touches
After the video renders, open the lip sync page to match mouth movements to new dialogue. The tool accepts a 10-second audio file and aligns it in one pass. For background music generate a 30-second loop with the music tool and drop it in during export.
Use Lip Sync Video when dialogue is central. Auto Captions adds subtitles sized for mobile viewing at 24-point font.
Credit costs and batch tips
A single 8-second clip at 1080p costs 12 credits on average. Run four variations in one batch to compare motion styles without extra setup time. Export the best take at 24 fps or 30 fps depending on platform needs.
Limitations to consider
Current models still struggle with text on signs or fast text changes inside the frame. Keep prompts under 60 words for best results. If a generation fails quality checks, regenerate once with a shorter prompt rather than adding more detail.
Motion Poster offers an alternative when you need looping animations instead of linear clips. Shorts Generator produces 15 to 60 second vertical videos ready for social platforms.
