[Video generation with AI](https://docs.vast.ai/video-generation) has come a long way. If you saw the infamous AI-generated video of Will Smith eating spaghetti a couple of years ago, you probably remember how unnatural and distorted the clip looked\! But that was just the beginning.

Things look very different today, with more advanced video generation tools producing much higher quality results. Today's models can create photorealistic visuals with smooth, consistent motion as well as stylized and cinematic effects if that's what's called for.

AI video generation has become a practical tool for anyone who needs an easy way to go from text to video, no matter the project. The right templates make that process even simpler.

With that in mind, let's take a look at a few of the best [AI video generation](https://docs.vast.ai/video-generation) templates available today.

### 1\. [ComfyUI \+ LTX Video](https://cloud.vast.ai/?ref_id=62897&creator_id=62897&name=ComfyUI%20%2B%20LTX%20Video)

[**LTX Video**](https://github.com/Lightricks/ComfyUI-LTXVideo) is a group of open-source AI video models built for high-quality diffusion-based video generation. It offers both speed and precision, generating high-resolution videos **up to 60 seconds long** (with some versions of the model limited to **10 seconds**), often in less time than it takes to watch the resulting video.

How is this possible? LTX Video uses a unique approach where it **compresses video data 192 times smaller than the original** – past the limits of what most models can achieve – while still maintaining crisp visuals and smooth, realistic motion. A bonus is that this drastically reduces the amount of memory and compute required. In fact, LTX Video is optimized specifically for consumer-grade GPUs.

While most diffusion models use a two-step pipeline where a second-stage model sharpens details, LTX Video does decoding and cleanup in just one step. With a Video-VAE (variational autoencoder) and a denoising transformer combined into a single integrated system, there's no need to patchify the video stream, and high-quality results are possible even under heavy compression.

This [template](https://cloud.vast.ai/?ref_id=62897&creator_id=62897&name=ComfyUI%20%2B%20LTX%20Video) pairs LTX Video with **ComfyUI**, a modular, node-based interface for Stable Diffusion workflows. Together, they serve as a seamless way to run efficient, high-compression video pipelines with a user-friendly interface.

### 2\. [Mochi](https://vast.ai/article/generating-videos-with-mochi-on-vast.ai)

Designed to excel in quality of motion as well as prompt adherence, [**Mochi**](https://github.com/genmoai/mochi) is a state-of-the-art open-source video generation model that performs competitively with leading closed models.

It demonstrates strong motion quality, generating smooth videos at **30 frames per second for durations of up to 5.4 seconds.** Fluid dynamics, fur and hair simulation, and human movement are all rendered with impressive realism.

Mochi's alignment with text prompts is also exceptional. Generated videos accurately depict the given input, allowing users to control characters, settings, and actions with a high degree of detail. Prompt adherence is benchmarked with a vision-language model and generated videos are evaluated using Gemini to ensure accurate, consistent results.

However, keep in mind that the initial release of Mochi only generates videos at **480p**, and the model is optimized for photorealistic styles, so animated content is not recommended.

### 3\. [Open-Sora](https://cloud.vast.ai/?ref_id=62897&creator_id=62897&name=Open-Sora)

[**Open-Sora**](https://github.com/hpcaitech/Open-Sora) is an open-source video generation model with a streamlined, user-friendly platform that lowers the barrier to efficient, high-quality video content creation. It can produce videos **up to 15 seconds long, at resolutions of up to 720p, with any aspect ratio.**

The model also supports a wide range of visual generation tasks: text-to-image, text-to-video, and image-to-video generation. This flexibility means users can run diverse workflows within a single framework.

Notably, Open-Sora introduces two innovations. The first is the Spatial-Temporal Diffusion Transformer (STDiT), a framework that decouples spatial and temporal attention. The second is a highly compressive 3D autoencoder that not only makes representations more compact but also accelerates training with its own ad hoc training strategy.

These features allow Open-Sora to generate high-quality results more efficiently – and with a ready-to-use template, it's easier than ever to start experimenting.

### Final Thoughts
