AIREITERCreate with FLUX 3 Video
Use one production model for text-to-video, ordered-keyframe animation, and source-video continuation.
Text to Video
Describe the scene, motion, camera, and sound to generate a complete video from text.
Ordered Keyframes
Animate 1-10 images in playback order. The first and last images define the endpoints, with intermediate frames distributed between them.
Video Extension
Continue one source MP4 while preserving subject identity, lighting, and camera direction.
Synchronized Audio
Generate native synchronized audio, or disable audio when a silent output is required. Disabling audio does not change the price.
AIReiter FLUX 3 Video Test Results
Text to Video
HD, 21:9, Safety Tolerance 0, audio off. Delivered H.264 at 1440x608 for 5.04 seconds. Estimated and final charge: 88.4 credits.
Ordered Keyframes
Two ordered images, FHD, 1:1, Safety Tolerance 2, audio on. Delivered H.264 at 1440x1440 for 5.04 seconds with an AAC audio track. Estimated and final charge: 150.8 credits.
Video Extension
HD, 9:16, Safety Tolerance 4, audio off. A 5-second request delivered H.264 at 704x1280 for 3.00 seconds. Estimated and final charge: 213.2 credits.
Retry and billing behavior
One text-to-video attempt returned a temporary upstream error and was not charged. Retrying the identical request completed successfully. The three successful tests reduced the test balance by exactly 452.4 credits.
Prompts Used in the Verified Tests
Reproduce the same requests or use them as starting points for your own evaluation.
Text to Video Prompt
A red ball rolls slowly across a clean white studio floor, static camera, no text.
Keyframe Prompt
The camera slowly pushes toward the landscape while sunlight moves across the scene. The test used two ordered keyframes from the AIReiter image sample set.
Video Extension Prompt
Continue the camera motion smoothly as the scene advances, preserving subject identity and lighting.
How to compare outputs
Keep the prompt and source media fixed, then change one control at a time. Compare motion continuity, prompt adherence, audio synchronization, actual duration, and final credit usage.

FLUX 3 Video FAQ
What can FLUX 3 Video generate?
It supports text-to-video, image-to-video with 1-10 ordered keyframes, and source-video extension.
How long can a FLUX 3 Video clip be?
Requests support integer durations from 5 to 20 seconds. Video extension can produce a shorter final clip; AIReiter displays and charges the requested-duration price before submission.
Does FLUX 3 Video generate audio?
Yes. Synchronized native audio is enabled by default and can be disabled without changing the price.
What does Safety Tolerance mean?
It controls content-filter strictness from 0 to 4. Zero is the strictest and four is the most permissive.
Does AIReiter expose FLUX 3 draft mode?
No. AIReiter exposes only the three production modes so an internal task ID is never confused with a provider draft task ID.
Which model ID should I use with the API?
Use flux_3_video with POST /api/openapi/submit, then poll POST /api/openapi/query using the same out_task_id.
