A model is only as good as the data it learns from. The "Vox" in Vox-adv-cpk.pth.tar refers to (typically VoxCeleb1 or VoxCeleb2), a large-scale audiovisual dataset collected from open-source YouTube videos.
model; specifically, it is the standard model fine-tuned for an additional 50 epochs with an adversarial discriminator to produce more realistic results. : It was trained on the
In machine learning, a checkpoint is a saved snapshot of a model's internal weights and biases at a specific point during the training process.

By passing vox-adv-cpk.pth.tar into a framework like the First Order Model Repository, you can take a still photograph of anyone (even a historical figure or a painting) and make them mimic the facial expressions, head tilts, and mouth movements of a live video actor. 2. Real-Time Video Call Avatars
The standard VoxCeleb checkpoint is strictly trained on a .
To understand the file's significance, it's helpful to grasp the key technical components it represents: A model is only as good as the data it learns from
: Identifies essential facial landmarks in both the source image and the driving video.
: Users have reported that the downloaded .tar file can sometimes appear broken or unsupported. This usually points to a corrupted download. The remedy is to re-download the file from a reliable source, ensuring the download completes fully and the file size matches the expected size (e.g., 716MB for the full version).
The technology powering vox-adv-cpk.pth.tar is the result of research by Aliaksandr Siarohin and colleagues, published at the prestigious NeurIPS conference in 2019 in a paper titled "First Order Motion Model for Image Animation". The genius of this model is its ability to learn motion without any human-provided annotations, a process known as self-supervision. : It was trained on the In machine
Generating dynamic video ads where a single model's face can be animated to deliver personalized video greetings. How to Use Vox-adv-cpk.pth.tar in Your Code
You must download the vox-adv-cpk.pth.tar file and place it in the designated checkpoint folder of your project directory.
Users often encounter this file when setting up software like Avatarify-python or FaceIt Live .
: Only download the checkpoint from links explicitly provided in official, highly-starred GitHub repositories (such as Aliaksandr Siarohin's original GitHub organization).
The versatility of vox-adv-cpk.pth.tar is demonstrated by its integration into a wide range of projects beyond the core research repository. It has become a standard artifact for facial motion transfer:
