FLUX 3 Videoとは？20秒・音声つき動画生成の料金と他社比較

Starting today, an initial version of FLUX 3 Video for generation from text and images is generally available via the BFL API and select partners. ／ The model generates clips up to 20 seconds long in HD resolution, with Full HD output via upscaling and native audio created alongside the video. ／ FLUX 3 is our frontier multimodal model for generating and predicting video, audio, images, and actions. ／ In its initial form, FLUX 3 Video can create video clips of up to 20 seconds length with native audio. ／ We are releasing our model at HD (720p) and Full HD (1080p) resolutions … ／ Text-to-Video: Describe a scene in simple language or using a detailed prompt. ／ FLUX 3 follows complex instructions while generating natural movements, scene logic, and audio. ／ Image-to-Video and Keyframes: Start with an image, specify an end frame, or set multiple keyframes in a clip. ／ FLUX 3 Video connects these in sequence while following the intended visual language. ／ Video Continuation: Provide FLUX 3 Video with up to four seconds of existing video and audio and tell it what should happen next. ／ The model takes both components into account to continue movement, camera behavior, dialogue, and audio across the video seam. ／ Creating Multiple Shots: Create multiple scenes and camera angles within a single video, while keeping the sequence coherent. ／ Audio and Dialogue: Generate dialogue, sound effects, and ambient sounds along with the individual frames. ／ Multi-Linguality: FLUX 3 Video is built to be a powerful tool for people of many different ethnicities and languages. — 一般提供の開始形態（ページ掲載日 August 4, 2026）、クリップ長と解像度、モデルの位置づけ、および図表に挙げた6機能それぞれの説明より

| <strong>Text to Video</strong> | a prompt | 5–20 s | \$0.17/s hd, \$0.29/s fhd | \$0.06/s | ／ | <strong>Image to Video</strong> | a prompt + 1–10 images | 5–20 s | \$0.17/s hd, \$0.29/s fhd | \$0.06/s | ／ | <strong>Video Continuation</strong> | a prompt + your clip | 5–15 s | \$0.43/s hd, \$0.54/s fhd | \$0.12/s | ／ Every mode outputs 24 fps at `hd` or `fhd`, in aspect ratios 21:9, 2:1, 16:9, 4:3, 1:1, 3:4, and 9:16. ／ Drafts render at `hd`. — モード別の生成可能秒数と秒単価をまとめた表の3行、および全モード共通の出力仕様（フレームレート・縦横比・Draft の解像度）の記述より

Draft Mode: Enables the exploration of creative directions easily. ／ A draft generation returns a fast preview of your prompt at a fraction of the cost, so you can iterate on ideas instead of waiting for a full high-quality generation every time. ／ When a draft is satisfactory, FLUX 3 renders the video at full quality. ／ It includes the same subjects, same composition and same motion so the final output matches the version you approved. — Draft モードの目的、下書き生成の費用と速度、および本生成へ引き継がれる要素に関する記述より

Human raters found it to be the preferred model for both text-to-video and image-to-video generation. ／ In our internal evaluation, FLUX 3 outperforms existing SOTA models in text to video generation by a solid margin. ／ It ties Seedance 2.0 and beats all other existing SOTA models in image-to-video. ／ Our next releases will expand FLUX 3 Video for enhanced controllability and ship capabilities for new modalities. ／ Our roadmap further includes FLUX 3 Image for image generation and editing, and FLUX 3 Dev as an open-weight variant. — 人手評価と内部評価の結果、比較対象モデル、および今後のリリース計画に関する記述より

Result URLs are signed and expire about 2 hours after the job finishes. ／ Download the video promptly once the status is `Ready`. ／ The signed result URL is valid for about 10 minutes — download it promptly. — 本文中の結果URL失効に関する記述、および同一ページの図解ラベル内の記述より（両者で期限の値が異なる）

We are committed to responsible development and deployment of AI models, and apply multiple layers of mitigation before, during, and after release to combat the risk of misuse. ／ Working with a trusted third-party partners, Cinder ／ we evaluated FLUX 3 Video for a range of risks prior to release to validate our mitigations across the full range of supported modalities, including non-consensual intimate imagery (NCII) and child sexual abuse material (CSAM). — 責任ある開発と展開の節における、緩和策の適用時期、第三者パートナーの名称を含む評価実施、および評価対象リスクの範囲に関する記述より
