Dear Fellow Scholars, this is Two Minute  Papers with Dr. Károly Zsolnai-Fehér. In 2021, scientists at Google had an absolutely  insane idea. Do you see this photo? Yes? They   said, now, let’s give this to the AI, and ask  it to fly into this photo. Insanity. And yet,   it worked like this. Absolutely  amazing. It was not given a video,   and not ... Read More

Questions & Answers

Q: What is the main challenge in creating AI-generated videos with long-term consistency?

The main challenge is to ensure that the generated content remains coherent and does not morph into unrelated scenes over time, which has been a struggle for previous techniques.

Q: How does the new technique from NVIDIA compare to previous methods in terms of realism?

The new technique surpasses previous methods in terms of realism, as confirmed by both neural network perception and user studies, where a significant majority preferred the new technique over the previous state-of-the-art.

Q: What are some advantages of the new technique over previous ones?

The new technique not only improves long-term consistency but also excels in synthesizing new scenery, providing better camera motion and rotation. Additionally, it offers super-resolution, enhancing video quality by adding more detail.

Q: Are there any limitations or issues with the new technique?

Although the new technique shows remarkable progress, it still has some artifacts, morphing, and other minor issues. It is an ongoing research process, and further advancements can be expected in future papers.
