In the era of short videos, almost anyone can become a creator and publisher of short videos. However, producing a video is actually a time-consuming and energy-intensive task, involving defining themes, varying shooting techniques, editing skills, finding suitable materials, and more.
Is there an efficient crash course method? Yes, using an AI video generator can solve more than half of the video production issues. Current AI video generation technology is already very mature. With just a sentence or even an image, it's possible to achieve text-to-video or image-to-video generation. Even video camera angles and color changes can be adjusted with AI assistance.
For example, the popular "Chinese style" in recent years would be time-consuming and labor-intensive to produce these types of videos manually, especially in terms of props and material applications. In fact, you can try the AI video generation feature, which is available in the AI Video Generator tool on the 302.AI platform.
Let's take a look at the process and effects of the AI Video Generator.
Luma Model Example
Text-to-Video
1、Choose the model
The following example will showcase the Luma model.
There are many domestic and international video generators on the market. How can you experience different AI video generators simultaneously? Besides using various official websites, you can also visit the 302.AI platform, where the AI Video Generator incorporates popular models such as Luma, Kling, Runway, Cog, and Minimax.
Next, we'll demonstrate using the Luma model as an example.
2、Input Prompt
The Luma model has text-to-video functionality. Enter descriptive words in the [Prompt] section.
For instance, if you want to generate a video about a sunset scene, you can input this ancient Chinese poem in the AI Video Generator's image content: "Withered vines, old trees, drowsy crows. Small bridge, flowing stream, cottages, Ancient road, west wind, lean horse. The setting sun in the west, A heartbroken person at the end of the world."
Click [Generate Video] and wait for the video to be generated. Other features can be left unset for now.
3、Camera control
With the Luma video model, you can also adjust camera control. Here, let's try selecting "Move Up" to see the generated effect. You can clearly see that the video with camera control added has an upward camera movement.
4、Enable/Disable loop
From the previous sample videos, you can see that under the "Disable loop" function, the generated video has a noticeable left-right movement. If you Enable loop function, AI will create seamless, looping videos from text descriptions, images, or key frames, which can be understood as dynamic wallpapers.
5、Video generation
You can see the video effect generated using the Luma video model. The elements mentioned in the poem such as ancient vines, old trees, small bridges, flowing water, cottages, and sunset are all displayed.
Image-to-Video
1、Add video images
Using the Luma video model, there's also a function to add video images. By adding first and last frame images, you can generate videos without adding video content descriptions.
2、Determine video ratio
Click to generate the video, determine the video ratio, and then wait for the video to be generated.
3、Camera control
Using the Luma video model, you can also adjust camera control. Let's try selecting "Move Up" here.
Compared to the previous video, you can see that the video with camera control added has a noticeable upward camera movement.
4、Enable/Disable loop
From the previous sample videos, you can see that under the "Disable loop" function, the generated video has a noticeable left-right movement. If you Enable loop function, AI will create seamless, looping videos from text descriptions, images, or key frames, which can be understood as dynamic wallpapers.
5、Video generation
You can see the generated video effect. Without content description, the final generated video is not simply a combination of two images; the horseback rider in the last frame also appears in the scene of the first frame.
Other Video Models
-
Kling——an AI video generation tool launched by Kuaishou
-
Runway ——an American company focused on artificial intelligence software development
-
Cog——developed by Beijing Zhipu AI Company
-
MiniMax——from Shanghai Xiyu Technology Co., Ltd.
From the video generation effects of these 5 models, for text scene descriptions, the main subject, elements, and scene requirements can be displayed as required in most cases. When human or animal actions appear, AI video generation has some flaws to varying degrees, such as some inharmonious or suddenly disappearing limb movements.
Of course, if there are no specific details that need to be presented, it is still possible to assist video creation through refined descriptions + multiple AI generations + editing.
