To keep track of your credit usage, you can inspect the response headers of each API call. The x-remaining-credits property will indicate the number of remaining credits in your account. Ensure you monitor this value to avoid any disruptions in your API usage.
V-Express
The V-Express model is a groundbreaking advancement in the realm of portrait video generation. It combines deep learning techniques with progressive training and conditional dropout operations. V-Express leverages generative models to create portrait videos from single images. It takes into account pose, input image, and audio, resulting in emotionally resonant videos. V-Express addresses the challenge of balancing different control signals. Whether it’s text, audio, pose, or image reference, V-Express ensures that weaker conditions contribute effectively to the final output.
