About
HunyuanCustom is a multi-modal customized video generation framework that emphasizes subject consistency while supporting image, audio, video, and text conditions. Built upon HunyuanVideo, it introduces a text-image fusion module based on LLaVA for enhanced multi-modal understanding, along with an image ID enhancement module that leverages temporal concatenation to reinforce identity features across frames. To enable audio- and video-conditioned generation, it further proposes modality-specific condition injection mechanisms, an AudioNet module that achieves hierarchical alignment via spatial cross-attention, and a video-driven injection module that integrates latent-compressed conditional video through a patchify-based feature-alignment network. Extensive experiments on single- and multi-subject scenarios demonstrate that HunyuanCustom significantly outperforms state-of-the-art open and closed source methods in terms of ID consistency, realism, and text-video alignment.

About
Pika Soundtrack is a video-to-audio model that turns silent video into a native soundtrack complete with motion-aware sound effects, music, ambience, and voiceover that follow what happens on screen. Users can leave the prompt blank to generate a full soundscape automatically or provide direction specifying what the model should emphasize, include, or leave out. Rather than simply generating sound with video attached, the model is designed to understand what is happening in a scene, place each sound at the right moment, and keep every audio layer coherent throughout the full video. This synchronization approach allows sound effects, ambience, music, and speech to feel as though they belong naturally within the same scene. Pika reports that, in its full-duration benchmark, Soundtrack achieved the strongest semantic alignment and lowest audiovisual desynchronization among the models tested, including LTX-2.3 Foley V2A, HunyuanVideo-Foley, and MMAudio v2.
