Movie Gen is designed to offer anyone, regardless of experience, access to powerful video creation tools. Meta believes that creativity should not be limited by technical expertise or expensive software.
This new AI tool follows Meta’s previous advancements such as the Make-A-Scene series, which allowed users to generate images, audio and 3D animations.
This new tool takes the concept by blending multiple media formats including video and sound.
By integrating diffusion models and building on its Llama Image foundation models, Meta has been able to enhance the quality and efficiency of its generative tools.
Movie Gen’s core functionality is its ability to generate videos based on simple text prompts. Using a 30-billion-parameter transformer model, it can produce videos up to 16 seconds long, rendered at 16 frames per second.
The model excels at creating videos with complex object motions, subject interactions and dynamic camera movements, making it capable of producing more realistic and engaging content than many existing tools.
One of the feature of Movie Gen is its ability to take an individual’s image and integrate it into a personalized video.
Users can upload their own images and Movie Gen will use text prompts to create a video while preserving the person’s identity and movements. This capability is useful for personalized video messages, ads or creative content.
The tool offers video editing options, allowing users to make localized or global changes to their videos without affecting the overall quality.
For instance, users can easily add, remove or modify specific elements such as changing backgrounds or adjusting objects within the frame, based on simple text inputs.
The tool’s advanced editing feature distinguishes it from other AI models that struggle with precise modifications.
Movie Gen also generates audio that matches the video content. Its 13-billion-parameter model can generate sound for up to 45 seconds including sound effects, background music and ambient noises.
The audio is perfectly synced with the visual elements and users can extend the soundtrack coherently for longer videos.
Meta News on Movie Gen also highlights the tool’s ability to generate realistic and well-timed sound effects such as engine noises or weather-related sounds like thunder and waterfalls. This level of audio-visual synchronization enhances the overall quality of the videos.
Meta News confirms that Movie Gen is the latest phase in Meta’s advancing creativity through AI. The company envisions a world where anyone, regardless of skill level, can create high-quality content with minimal technical barriers.
Movie Gen’s development is rooted in Meta’s AI research. Meta began with the Make-A-Scene series focusing on creating static images and 3D animations, before progressing to the Llama Image foundation models, which improved image and video quality.
Now, with Movie Gen, Meta is combining multiple modalities video, sound and editing capabilities into one powerful tool.
The model is trained on vast datasets including a mix of licensed and publicly available content. Although Meta has not provided specific details on the datasets used, it’s clear that the data spans a wide range of media including Instagram and Facebook videos, as well as other sources.
Movie Gen’s transformer-based architecture with 30 billion parameters for video and 13 billion for audio, allows it to process large amounts of data efficiently.
This enables the model to handle complex tasks like object motion and audio synchronization.

Meta has conducted extensive testing and evaluation of Movie Gen. Human evaluators consistently rated it higher than similar models from other companies like Runway’s Gen3 and LumaLabs.
Meta News reports that the evaluation covered various parameters such as video quality, audio synchronization and the accuracy of text-to-video translation.
Movie Gen generates videos at 768p resolution, a somewhat unusual but effective choice. The system then upscales the output to 1080p. The tool can also generate video at a standard 24 FPS when users opt for 10-second clips.
This tool requires long processing times for video generation, which could hinder real-time or high-volume content creation.
The tool’s default frame rate of 16 FPS may not suit all users. While it supports up to 24 FPS for shorter videos, users seeking higher quality or cinematic frame rates might find the current options limiting.
The tool does not generate voice likely due to the complexity of syncing lip movements with speech. Meta has acknowledged that this is a challenging feature to implement and could lead to issues like uncanny results in video outputs.
Movie Gen can generate high-definition videos from simple text prompts. It uses a 30B parameter transformer model capable of generating videos of up to 16 seconds at a rate of 16 frames per second.
The model excels in reasoning about object motion, interactions between subjects and objects, and simulating camera movement. This results in more realistic and dynamic content generation compared to previous industry models.
This tool can take a user’s image and create personalized videos by combining it with a text prompt. This provides creators the ability to inject themselves or their likeness into custom video content, preserving personal identity and maintaining realistic human motion.
This functionality opens up opportunities for personalized storytelling, marketing campaigns or even virtual avatars for content creators who want to showcase their unique style.
One of the most features of Movie Gen is its precision in video editing. By combining advanced image and video generation techniques, it allows for both localized and global changes to existing footage.
Users can make localized edits like adding, removing or replacing objects within a scene. They can also apply global modifications such as changing the background or altering the style of the video.
Unlike traditional editing software that requires specialized skills, Movie Gen simplifies the process with text-based commands, providing creators with greater control and flexibility.
Movie Gen also features a powerful audio generation model. This 13B parameter model can generate high-quality, synchronized audio based on both video content and text prompts.
The AI model supports the creation of ambient sounds, Foley sound effects and instrumental background music. The audio generation system can extend sounds to match longer videos.
