[App] 4× Upscale, Face Reference in Product to Model, and Prompt Support for Video Creation

This update brings several major improvements across image and video generation tools:

4× Image Upscale

Image Upscale now supports 4× enlargement, delivering true 4K-level detail with reliable results.

While 2× remains recommended for the most natural and stable outcomes, 4× offers an excellent option when maximum resolution is desired.

Face Reference in Product to Model

You can now apply Face Reference directly in Product to Model, enabling complete identity consistency from product photo to final model showcase.

This expands full identity control across Product to Model, Model Swap, Model Creation, and Edit — ensuring the same face can appear seamlessly across your entire workflow.

Prompt Support in Video Creation

You can now add short text prompts to guide motion or mood in video generation.

For best realism and aesthetics, we still recommend using no prompt, but this option gives added flexibility when specific direction is required.
