New in HunyuanVideo 1.5 is Tencent’s compact 8.3-billion-parameter open-weight approach to text-to-video and image-to-video generation. Base outputs are 480p or 720p; a separate video super-resolution module scales them to 1080p. Native audio is absent.
The architecture combines a DiT with Selective and Sliding Tile Attention to reduce the cost of longer video sequences. Step-distilled checkpoints accelerate image-to-video generation. The 1080p result is therefore a super-resolution output, not the model’s native resolution.
Text-to-video and image-to-video remain separate. Their input tasks differ, so they do not receive a combined overall rank.
Methodology and source
Benchmark sources at a glance
Each evaluator measures different capabilities under its own conditions. Test series, composite indices and their components stay separate. The detailed results below retain their scales, configurations and source dates.
No active result from the reviewed external evaluators can currently be attributed to this model. Other source evidence remains available below.
Coverage is not a quality ranking. Overlapping tests and multiple settings do not count as independent experiments. Vendor claims, historical and disputed results are excluded from this overview and remain labelled in the detailed evidence.

Video sample from our test
This video exists as a documented run for the exact model version. Playback is muted.
Motion and physical consistency
This sample tests Anatomy, object consistency, camera tracking, rain, and reflections.
Prompt and settings
Generate exactly one continuous five-second 16:9 cinematic video. A fictional bicycle courier in a mustard-yellow raincoat rides a red city bicycle from left to right across a rain-wet Hamburg street at blue hour for the entire clip. The camera tracks her smoothly at waist height. Both hands remain visible on the handlebars, the bicycle geometry stays physically correct, and a transparent umbrella fixed to the bicycle moves naturally in the wind. Wet-street reflections and raindrops follow realistic physics. No cuts, no slow motion, no text, no logos, no subtitles, and no audio.
