14 Best AI Video Generators in 2024 (Text to Video)

With the groundbreaking AI technology this year, we've seen generative AI evolving fast from chatbots like ChatGPT to image creation by Midjourney. AI video editing and AI-powered video remastering and upscaling have already been implemented into practice by Adobe and DaVinci Resolve, which promises to redefine the way we create and edit videos.

Now, text-to-video AI technologies seem to be the big thing in the spotlight. In this article, we delve into 14 innovative AI video generators and how they transform video creation. (The list is constantly updating.) Some of them are set to release, and some are already available to use for everyone. At the end of the post, we also provide you some tips for enhancing AI-generated videos quality. Just read on.

1. Sora

Best for: converting texts to high fidelity videos, animating still images, and expanding existing videos.

Sora is the latest and most promising text-to-video AI model from OpenAI. From the official teaser, we can see that it outperforms almost all the existing AI models. It can create detailed scenes with multiple characters, specific movements, and accurate details of the subject and background like they were in the physical world. The model understands language deeply, allowing it to interpret prompts accurately and create compelling characters with vibrant emotions. Sora can also generate multiple shots in a single video while accurately maintaining characters and visual style.

Currently, Sora is opening up to red teamers to evaluate key areas for potential harm or risk and some visual artists, designers, and filmmakers to gather professional feedbacks for further improvements. Learn how to use Sora with early access here.

Price: Unknown

Pros:

• Better understanding and simulating physics in the real world than other models.
• Videos generated by Sora can be up to 1 minute long.
• It has a specific team working on misinformation, hateful content, bias, and the IP of others.

Cons:

• It cannot always accurately simulate complex physics in a scene or understand specific cause-and-effect instances.
• It's currently not available to common users.

2. Google Lumiere

Best for: creating videos from texts and still images and editing specific portions of the videos.

The development of text-to-video AI is rapidly advancing, and Google Lumiere is once again joining the game. This new model claims to create consistent and realistic movement across the whole clip. Unlike existing models that synthesize distant keyframes followed by temporal super-resolution, it uses spatial and temporal down- and up-sampling, and leverages a pre-trained text-to-image diffusion model to directly generate full videos. In addition, it can edit any specific part of a video or a still image with a simple mask and prompt, and make videos in the target style.

Price: Unknown

Pros:

• Considerable improvements in image consistency.
• Multiple ways to create videos, including text to video, image to video, text & image to video.

Runway is a startup company that co-developed Stable Diffusion, a breakout text-to-image model in 2022. In Gen-1, you need to upload an existing video, then it modifies the video into a new style. This year, Runway unveiled Gen-2 which creates videos with nothing but words.

Built with a cutting-edge structure and content-guided video diffusion model, Runway Gen-2 analyzes and understands natural words accurately. Not only delivers footage that really makes sense, but it also synthesizes videos in any style as long as you can put your imagination into a text prompt. In addition to text-to-video features, Runway Gen-2 creates videos from images, videos, texts, and images mixed, turns mockups into animated renders, applies effects to certain subjects, renders untextured things into realistic, and customizes models.

Best for: synthesizing any footage online with zero shot.

Based on the existing text-to-image synthesis methods (e.g., Stable Diffusion), Picsart's AI research team (PAIR) has introduced a new approach to generating new video content from only texts. In the near past, AI-generated subjects and the background looked slightly different from frame to frame. But in Picsart's new methods, things look consistent and realistic. Moreover, you can use the new generative AI to turn the video to a new appearance by a prompt "make it Monet Impression, Sunrise style".

Unlike most research projects that take a long time to be deployed publicly, it won't be long until the PAIR text-to-video generative AI system becomes customer-facing. Picsart officially announces that it plans to release new software products that are built on this generative AI framework in the coming weeks. Now you get the open-source demo of Picsart Text2Video-Zero on Hugging Face and Github.

How to Enhance AI-generated Videos

Still, videos generated by AI tools, either reality videos or animations, do not look sharp and smooth enough. Because only a few AI apps are capable of generating videos in 4K and most of them are creating videos in SD at 24fps or 30fps.

When the footage is of a high resolution or contains a lot of movement, the AI video generator may struggle to keep up with a high frame rate and resolution. Besides, the capabilities of the AI video generator itself may also impact the maximum supported frame rate. Hopefully, VideoProc Converter AI, a powerful video processing program, helps overcome the limitations of AI video generators in in terms of frame rate and resolution.

VideoProc Converter AI features AI Super Resolution to enlarge SD videos and images to up to 4K and AI Frame Interpolation to boost FPS to 60fps/100fps/120fps and more. Besides, you can use its quick-edit tools to cut, crop, rotate/flip, and merge AI videos.

Download VideoProc Converter AI and make the AI-generated videos sharper and smoother now!

Step 1. Open VideoProc Converter AI. Open the Super Resolution panel.

Step 2. Import videos from any AI video generator by dragging and dropping.

Step 3. Go to the Model Settings. Choose the scale 2x, 3x, 4x, or just enhance video quality without changing the resolution.

Step 4. Choose the output format and click Run to export the upscaled video.

Tips. Exit from the Super Resolution panel. You can go on boosting the video FPS with AI Frame Interpolation, merging multiple clips into one file, cropping, rotating, etc.

Final Thoughts

AI video generators are mainly divided into two types – one for synthesizing videos from scratch with prompts, and the other for arranging videos with stock footage and graphics like presentation videos. Both of them can largely reduce the investment in filming and post-editing and bring more options to people who think conventional video editing software is a challenge to navigate.

On the other hand, with the arrival of an easier way to make realistic videos, text-to-video also brings new threats of misinformation. Chances are that a user instills a non-verified idea to the audience, pushes it as the truth, and supports its claim with lifelike footage. And that's why many companies like Google have decided not to open their AI generator models or source codes to the public until biased, violent, and deepfake content can be filtered out.

Still, the results are fascinating and even going to be better with the power of AI. Challenges are not only about machine learning, deep learning, and algorithms stuff, but also something moral under an effective system.
