【AI】2024年最强AI视频生成工具TOP 5，其中三款完全免费

The video script introduces Pixverse, a new and popular AI video generation tool that stands out for being completely free. Compared to other paid software, Pixverse's cost-free approach is highly attractive. The tool offers two methods of use: through its official website and via Discord. The website features sections for popular videos, user-generated videos, a collection of liked videos, and a character generation feature. The video creation process is straightforward, with options to create videos from text, image, or character. The script demonstrates text-to-video generation using an inspiring prompt, with style options including realistic, animation, 3D animation, and digital. The video dimensions and seed values are customizable, and the tool can generate two videos simultaneously. The script also covers image-to-video and character-to-video functionalities, emphasizing the tool's ease of use and quick video generation without server overload.

The script continues with a detailed look at Pixverse's character video generation, noting that despite some distortion in the character images, the generated videos maintain correct proportions. It explains how users can input prompts and utilize auto character prompts to enhance the fidelity of the generated videos. The video dimensions and seed values are also adjustable. The video showcases the character's ability to generate different backgrounds and segments, creating a narrative. The script then transitions to Pixverse's Discord integration, demonstrating how to use various commands for video generation, including animate, create, meme_face, and others. It also touches on the limitations and compares the character video generation to face-swapping software, noting that while the latter requires a two-step process, it may yield slightly better results.

The video script shifts focus to Runway, one of the earliest AI video generation software with powerful features. It highlights Runway's tools for video and image generation and focuses on the video generation tools. The Gen1 tool is for changing video styles, while Gen2 allows for text-to-video or image-to-video generation. Users can upload images, input prompts, and adjust settings such as seed values, interpolate frames for smoother videos, upscale resolution, and remove watermarks. The script also discusses camera controls like horizontal and vertical panning, tilting, and zooming. It introduces the motion brush tool, which allows for precise control over the movement of objects within the video. The Genmo software is also mentioned as another high-quality, free option for video generation, with a clean interface and straightforward video generation process.

The script describes Genmo's user interface and its capabilities for text-to-video generation, with settings for video dimensions, duration, motion intensity, batching, and looping. It also covers camera motion settings and the addition of special effects (FX) to enhance videos. Genmo's video generation is praised for its quality, and the script provides an example of a generated video of a cat surfing on ocean waves. The tool's image-to-video functionality is also demonstrated, where the software detects the uploaded image and generates a fitting prompt. The script then introduces Leonardo, a well-known image generation tool that has recently added video generation capabilities. It outlines the simple interface and process for generating videos using an uploaded image and adjustable motion intensity, noting the satisfactory results.

The final part of the script introduces Haiper, a free tool with three main functions: text-to-video, image-to-video, and video repainting. It details the process of generating a video from text with various style options and customizable seed values. The image-to-video function is showcased with an example of uploading an image and generating a beautiful video. The script then highlights Haiper's unique repaint video feature, which allows users to change the style, color, or certain subjects within a video. Examples are given where a video is transformed to feature a white lace dress and where a video's hair region is repainted to a deep brown color, demonstrating the tool's powerful editing capabilities.
