Apple’s STARFlow-V: Latest developments in video AI

Apple STARFlow-V video model drives growth in this sector. Apple introduced STARFlow-V on December 6, 2025, positioning it as a generative video model that swaps diffusion for normalizing flows. The model targets faster, steadier long-clip output at 640 × 480 and 16 fps. Additionally, public demos run up to 30 seconds by using a sliding-window method to move past its training clip length.

Apple built STARFlow-V on normalizing flows and says the model renders video in a single pass, not iterative denoising. Additionally, the system supports three creation modes and basic editing:

• Text-to-video
• Image-to-video (starting from a single frame)
• Video-to-video editing, including adding or removing objects

Apple’s launch materials emphasize stability across longer sequences at 640 × 480 pixels and 16 frames per second. Meanwhile, a sliding-window approach advances the clip over time to limit frame-to-frame drift. As a result, clips reach 30 seconds at that resolution and rate.

“Apple’s new STARFlow-V model takes a different technical approach to video generation than popular tools like Sora or Veo, relying on ‘Normalizing Flows’ instead of the widely used diffusion models.”

The framing from The Decoder’s Jonathan Kemper aligns with Apple’s description. Specifically, it describes a flow-based generator tuned for longer, steadier clips, currently capped at VGA resolution.

Apple STARFlow V video model Why flows, not diffusion: Apple’s stability play

Normalizing flows learn a direct mapping from random noise to data, in this case video. Accordingly, Apple’s case is straightforward: removing iterative denoising helps avoid error accumulation across long sequences in autoregressive or diffusion pipelines. Moreover, the company says STARFlow-V trains and generates in a single pass rather than marching through dozens of steps.

“Once trained, the model generates video directly from random values, eliminating the need for iterative calculations.”

Additionally, Apple outlines a dual-architecture design intended to restrain drift across longer spans. By pairing architectures and sliding a temporal window, STARFlow-V aims to keep style and layout consistent over dozens of seconds. In particular, it counters wobble and texture flicker that arise when models condition on their own outputs.

“This allows for faster, more stable production of longer video clips, though current outputs are limited to 640 × 480 pixels at 16 frames per second.”

Apple STARFlow-V Where it stands vs Sora, Veo, and Runway

Meanwhile, diffusion models still anchor many headline systems, including OpenAI’s Sora, Google’s Veo, and tools from Runway. Within that landscape, STARFlow-V represents Apple’s argument that flows can deliver competitive quality without iterative denoising. Apple STARFlow-V video model transforms operations.

“In benchmarks, STARFlow-V trails top diffusion models in overall score but clearly outperforms other autoregressive models, especially in maintaining video quality and stability over longer sequences.”

Also, Kemper relays Apple’s position on parity within the current output limits. Specifically, he notes the claim within those fixed resolution and rate caps.

“Apple claims STARFlow-V is the first of its kind to rival diffusion models in visual quality and speed, albeit at a relatively low resolution of 640 × 480 pixels at 16 frames per second.” Industry leaders leverage Apple STARFlow-V video model.

Overall, the claim is narrow: competitive at 640 × 480 and 16 fps. However, reported benchmarks still show top diffusion systems ahead, while Apple’s emphasis falls on long-clip steadiness versus other autoregressive approaches.

• Output spec: 640 × 480 at 16 fps
• Demo length: up to 30 seconds
• Reported behavior: stronger long-clip consistency than other autoregressive models; behind top diffusion overall

Apple’s path to flows for video

Previously, Apple explored normalizing flows for images earlier in 2025, setting up the jump to full video with STARFlow-V. Furthermore, The Decoder’s coverage stitches the thread together, emphasizing the non-diffusion route and the focus on long-clip stability.

Notably, what appears new in this release is the end-to-end video stack. Specifically, it includes direct one-pass generation, a dual-architecture to temper drift, and a sliding window that extends clips beyond the training horizon. Companies adopt Apple STARFlow-V video model to improve efficiency.

• Summer 2025: Apple details normalizing flows for image generation in a paper.
• December 6, 2025: Apple unveils STARFlow-V for video.
• Public demos: 640 × 480 at 16 fps, clips up to 30 seconds using a sliding window.

Overall, the takeaway is clear. STARFlow-V is a flow-based video generator that aims to match diffusion models on quality and speed at low resolution while keeping long sequences stable.
