Reading some news I came across this: Transforming Standard Video Into Slow Motion with AI or NVIDIA AI creates slow motion videos without "recording more frames", where Nvidia used an algorithm that turns a normal video into slow motion, but smoothes the movements in the video by creating/predicting more frames (frames) with interpolation and artificial intelligence.
A videos of the results can be viewed on Youtube.
Then a doubt arose, which is the interpolation of video frames (video frame Interpolation)?
Face to thick and short way they take what would be 1 frame and turns into 2 or 3 or 30. The human eye can capture around 30 images per second, so most videos are recorded in 30fps, now imagine that you want to take a video that has 1 second, or 30 frames, and put in slow motion resulting in 2 seconds of video for example. Ai you have to take an original video of only 30fps and increase to 60fps, but without losing the transition fluidity of frames to not look like a "stop motion". Basically between one frame and another this algorithm should create other N frames
