What is WAN 3 I2V?
WAN 3.0 Image-to-Video is the image-conditioned half of Alibaba's current WAN generation. It animates your start frame and generates audio in the same pass, so dialogue, music and effects arrive already in sync. The output follows your start frame's framing. Supplying an end frame turns the same endpoint into a first-to-last-frame interpolation. Three resolution tiers (480p, 720p, 1080p); billing is per second of output and rises with the tier, at the model's cost plus a flat 20% platform fee, shown before you spend. Upstream WAN 3 accepts up to 30 seconds in one generation. On FairStack it is capped at 16 seconds, the platform-wide ceiling for every video model.
