Sora is a video generation AI released by OpenAI on December 9, 2024, which allows users to generate high-quality video content through simple text input. Users only need to enter some short prompts such as "Sunset", "Racing" or "Outer Space", and Sora can generate corresponding videos based on these instructions. Whether it is creating creative ads, teaching videos or experimental content, Sora provides a powerful platform to help users quickly generate various videos. To use Sora, you first need to visit the official website and log in with your ChatGPT account. If you don't have a ChatGPT Plus or Pro subscription, you need to select and subscribe to a plan.
Sora has different subscription plans, suitable for users with different needs. For beginners, it is recommended to start with the basic plan, which supports generating 10,000 points per month. The maximum duration of each video generated in this plan is 20 seconds and the resolution can reach 1080p. Each generation can generate up to 500 videos. For users who need higher resolution and more generated points, a more advanced plan can be selected. ChatGPT Plus and Pro subscriptions offer more video generation points and higher video quality, respectively, but the corresponding costs are also higher. The basic plan is suitable for users who do not require high resolution or long videos, while a higher subscription plan provides professional users with more creative freedom and functionality.
In Sora's operation interface, users can see a layout similar to Midjourney. The homepage displays videos generated by other users and allows users to view videos saved by themselves. When creating a video, users can enter a concise and clear text description in the prompt box at the bottom. Sora also provides some preset filters, such as slow motion and black and white effects. Although these effects can add some creativity to the video, they may not be the most ideal, especially when the effects are special, users are advised to avoid using them. Users can choose the proportion and quality of videos according to their needs, and can save points starting from 480p. Avoid choosing a 1080p resolution unless it is really needed, as it consumes a lot of points. Pro users can choose to generate longer videos, while the basic plan supports generating only 5 seconds of videos. It is worth noting that users can also generate multiple videos at the same time, which is very useful when maintaining the consistency of the scene or character.
For best results, users need to write concise and clear prompt words. Try to avoid complex or vague descriptions as much as possible. Concise and clear descriptions can better help Sora understand the needs and generate corresponding videos. For example, “a sports car on the road” is easier to get the desired result than adding too much detail description. Since Sora currently does not support Chinese prompt words, it is recommended to use English input. In addition, simplifying prompt words is also an effective way to avoid poor video production. If the resulting video results show some minor errors, such as extra fingers on the hands or strange movements, users can try to adjust the prompt words to ensure the description is more concise.
Sora also provides a "Storyboard" function that allows users to divide videos into multiple scenes, each scene can generate different pictures based on different descriptions. Using the Storyboard function, users can create more complex video content, but they need to pay attention to the description of each scene to be clear and concise to avoid being too complicated. Manually splitting the lens is also a common method, especially when a specific scene or angle is required, users can manually adjust the storyboard to achieve the ideal effect.
There are some tips to help improve the video when using Sora. For example, after generating 480p video, users can use external software such as Topaz Video AI to zoom in to HD or 4K to achieve higher image quality. In addition, avoiding the background being too complex is also an important tip, as complex backgrounds and violent scene switching can cause Sora to have a chaotic effect. The most important thing is to keep the prompt words concise and focus on a clear scene or action, avoid adding unnecessary details.
Despite its powerful capabilities, Sora also has some known problems. For example, the generated video may have problems dealing with hands, hair, or complex movements, with more or less fingers, and may appear unnatural. In addition, when generating scenes containing text content, Sora sometimes experiences unconventional text errors, especially signage or other text descriptions. Another point is that when the prompt word involves "magic" or "witchcraft", Sora may generate more game-oriented pictures than the real scene style that users expect.
Overall, Sora is an exciting video generation tool that allows creators to generate high-quality video content with simple text input. By constantly experimenting and adjusting prompt words, users can use Sora to create very interesting and creative videos.
