Making film with “magic”

Meet Sora, the cool model from OpenAI. It can turn your words into videos like magic! Just tell Sora your idea, and watch it make a video right before your eyes.

How good is it?

Videos created by Sora look good on both big and small devices (设备), such as computers and smartphones. Sora can also make scenes with lots of people doing different things with clear details (细节). It also knows how things should look in real life.

Why is it so good?

Sora looks at many videos and learns from them by breaking them into very small bits (片段). It uses these bits to make a new video. The new video is gray at first and very messy—you can’t tell what’s in it. Then, Sora fixes the video until it looks good and smooth.

Sora also gets help from ChatGPT, which turns the user’s short sentences into clear instructions. This helps Sora make the video just as you asked.

Is it good enough?

Sora may find “busy” pictures hard to understand. For example, when a person moves, things around them change. In one video created by Sora, a grandma blows the candle on a birthday cake, but the flame (火焰) doesn’t move. Sora may not be able to tell “left” from “right” and mess up a person’s leg moves.

About 2500 years ago in ancient Greece, famous sculptor (雕刻家) Phidias created a huge statue (雕像) of Zeus king of the Greek gods. It stood in a big temple building in his honor in Olympia, the birthplace of the Olympic Games. The statue was destroyed by fire in the 5th century AD.

However, the students who come from Kenne saw State University in Georgia, used 3D printing technology to make the model of the statue according to the size of it.

The model was made out of plastic and took over six weeks to create. It opens up a whole new world of interacting with that sculpture. The sculpture was created for the Millennium Gate Museum in Atlanta Georgia. For an exhibit to remember the 20th anniversary of its 1996 Olympic Games. It remains the center of the museum today.

It was so great the difference of such a classical looking object. Students at the university use 3D printing technology to create modern works as well, it plays an important role in copying ancient treasures. “We really know the educational and building treasures, we are the owners of at this time, and we should try our best to pass them to the next generation.” Cook said.

Historically, most cars have run on gasoline（汽油）, but that may change in the future: cars can also run on other liquid fuels（液体燃料）and electricity.

Gasoline is from oil. The energy in gasoline comes from hydrocarbons（碳氢化合物）. Gasoline provides great power for cars. However, it causes environmental problems, like air pollution and temperature rise. So gasoline can’t be the best fuel.

Another choice is electricity. Electricity cars can be as efficient（效能好的）as cars using gasoline. And they produce less pollution. But electric cars themselves are more expensive. Good news is that the cost has been lower and there are more and more places for the cars to get electricity ever since 2010.

The other choices are other liquid fuels. Many of these can be stored in the same places as gasoline, and used in the same cars. They can also be friendly to the environment.

One way to make such fuels is to get CO₂ from the air and put it in water. Through chemical reaction, hydrocarbons can be created. However, these fuels take up more space.

Another way is to make such fuels from plants which take in carbon from the air. These fuels are greener in use. But not all of them can be as efficient as gasoline.

For a fuel to be the best, people have to be able to afford it. Unluckily, almost every green technology is more expensive than that of using gasoline. Governments and car producers are doing everything they can to cut down the costs. In the end, the best fuel will be both affordable for car users and green for our planet.
