Video & Audio
FLUX 3 Max video generator with sound, from text or a photo
What Flux3Max.io helps you do
It removes the guesswork and commitment from making a short video with sound. You describe a scene or start from a photo, see the exact price next to the button before you generate, and pay per second instead of subscribing. A failed video is refunded and the first clip is free, so trying it costs nothing.
Who Flux3Max.io is for
Short vertical videos for TikTok, Reels and Shorts, product and ad clips, bringing a photo to life, B-roll and storyboard tests, anime and fantasy scenes.
About Flux3Max.io from the developer
Flux3Max.io is an online video generator built on FLUX 3 Max, the video model Black Forest Labs and fal released in October 2026. You type what should happen, or start from a photo as the first frame (and a second one as the last), and it makes a 5 to 20 second video with sound, in 720p or 1080p, in shapes from vertical 9:16 to ultra-wide 21:9.
Pricing is per second and shown next to the button before you press Generate: 36 credits a second at 720p, 62 at 1080p. Credit packs are one-time, from $9.90 (1,000 credits) to $149.90 (18,000 credits), with no subscription, and credits do not expire. New accounts get 180 free credits, enough for a 5-second 720p clip, and failed videos are refunded. Videos stay in your history for 30 days.
The site also has an example wall with the exact prompts and a "Use this prompt" button, plus a keyframe timeline for up to 10 frames. It is aimed at short vertical videos for TikTok, Reels and Shorts, product and ad clips, bringing a photo to life, B-roll and storyboard tests.
