 We have verified the execution on a machine equipped with a single NVIDIA H100 80GB GPU. However, we believe it should be possible to run the model on any machine equipped with an NVIDIA GPU with 16GB or more of VRAM. 
 
-Terra consists of an Image Tokenizer, an Autoregressive Transformer, and a Video Refiner. Due to the complexity of setting up the Video Refiner, please refer to the [ACT-Bench repository](https://github.com/turingmotors/ACT-Bench) for detailed instructions. Here, we provide an example of generating video continuations using the Image Tokenizer and the Autoregressive Transformer, conditioned on image frames and a template trajectory. The resulting video quality might seem suboptimal as each frame is decoded individually. To improve the visual quality, you can use Video Refiner.
