RefDecoder: Enhancing Visual Generation with Conditional Video Decoding

Bohan Fang, Ranjay Krishna, Xiang Fan, Yuheng Wang, Zhongzheng Ren

RefDecoder adds reference-image conditioning to video VAE decoders through attention, yielding up to 2.1 dB PSNR gains and better consistency on I2V, editing, and style-transfer tasks.

Claims

C1strongest claim

We introduce RefDecoder, a reference-conditioned video VAE decoder by injecting high-fidelity reference image signal directly into the decoding process via reference attention... achieving up to +2.1dB PSNR over the unconditional baselines on the Inter4K, WebVid, and Large Motion reconstruction benchmarks.

C2weakest assumption

That equal conditioning of the decoder via reference attention is sufficient to preserve structural integrity without introducing new artifacts or requiring any fine-tuning of the rest of the pipeline.

C3one line summary

RefDecoder adds reference-image conditioning to video VAE decoders through attention, yielding up to 2.1 dB PSNR gains and better consistency on I2V, editing, and style-transfer tasks.
