Hunyuan (Tencent's HunyuanVideo) and LTX (Lightricks' LTX-Video and LTX-2 family) are both open-weight video models you can run locally, but they optimize for different things. Hunyuan is the pick for silent clips with strong motion and image-to-video consistency, while LTX is the pick for speed and, since LTX-2, synchronized audio and video in one pass. Styleframe (styleframe.ai) is not a third option in this comparison; it complements either model inside an After Effects or Nuke workflow, where artists keep keyframe and reference control over shots they composite there.

Hunyuan at a Glance

HunyuanVideo is Tencent's open-source video model. The current HunyuanVideo 1.5 has 8.3 billion parameters, was released in November 2025, and handles text-to-video and image-to-video in one pipeline. The official repo lists a 14GB VRAM minimum with offloading, and a built-in super-resolution stage reaches 1080p. It differs from LTX in that it generates silent clips and has historically been slower, so any sound is a separate task in your edit. Pick it if your priority is motion quality and a faithful first frame, and you already build audio in Premiere Pro or After Effects.

Hunyuan has also moved a lot. The original 13B model wanted around 24GB of VRAM, so older comparisons describe a much heavier tool than 1.5 is. Reports on its image-to-video are mixed. One 2025 stress test called the early image-to-video release unready for production, with stiff human motion. Another recent comparison credits the 1.5 pipeline with holding product and face identity well. Test your own subjects before committing.

LTX at a Glance

LTX is Lightricks' model family. LTX-2, open-sourced in January 2026, generates synchronized video and audio in a single pass, and the LTX-2.3 update in March 2026 improved prompt adherence and added native vertical 9:16 output. One 2026 write-up describes clips up to 20 seconds at native 4K and 50fps. Compared with Hunyuan, LTX has historically prioritized speed, and its audio-aware generation is the clearest functional difference. Pick it if you iterate heavily, need long or high-resolution output, or want a draft with sound already in place.

The older LTX-Video line is worth separating from LTX-2. It was a roughly 2B-parameter model that ran on about 8GB of VRAM and was praised for speed and clip length, but it trailed Hunyuan on quality in community benchmarks. In one early-2025 ComfyUI test on an RTX 4090, LTX rendered a short clip in about 30 seconds, while Hunyuan took about three and a half minutes. That comparison predates both current versions, so treat it as a sign of each model's design priorities rather than current numbers.

Where They Differ in Practice

Audio and Post Workload

One creator who tracked cleanup time on the same brief found the LTX clip took about 6 minutes to finish, against roughly 14 for the Hunyuan clip, almost all of it spent building an audio bed. That is one person's test, not a benchmark, but it shows the real split. LTX hands you a more complete draft, and Hunyuan hands you a cleaner picture that needs more built around it. If sound design is already part of your timeline, that gap matters much less.

Prompt Handling

LTX-2.3 got a larger text connector, and reviewers report tighter adherence to timing and motion descriptions. Hunyuan 1.5 offers bilingual prompting, glyph-aware text encoding, and camera-motion conditioning for pans, dollies, and tracking shots. English-only teams get less from the bilingual feature, but the camera control suits shot-based work.

Hosted Pricing

If you use hosted APIs rather than local weights, one public aggregator lists Hunyuan Video at $0.08 per video and LTX-2.5 Fast at $0.54. Those are list rates that shift with duration and resolution, so treat them as a rough indicator only. Both models can also be self-hosted.

Which Should You Choose?

Choose Hunyuan if you want strong motion, image-to-video from a locked first frame, and you handle audio separately. Choose LTX if you iterate often, need sound-synced drafts, longer clips, higher resolution, or vertical delivery. Some artists may run both: LTX to explore ideas quickly, Hunyuan when a specific shot needs steadier motion.

Neither model is a finished-shot tool on its own. Both produce clips that still need grading, cleanup, and compositing, and neither gives you frame-level direction beyond prompts and an image or two. Generation speed is only one part of the cost, because clips that drift from your art direction cost time in revisions.

Where Styleframe Fits

Styleframe is for the stage where a look has to match a brief rather than a prompt. It works from reference images, video clips, and keyframes, and it exports image sequences you can bring into After Effects or Nuke. That makes it a complement to Hunyuan or LTX, not a replacement. You might use either open model for rough exploration, then use Styleframe where you need controlled, non-destructive iteration on specific shots before compositing.
