Video that shows the exact moment proof appears — smart, simple, and clear
This new system answers questions about videos and also points out when and where the proof lives in the clip.
Instead of only giving a text answer, it marks the key timestamps and draws bounding boxes around the objects it used, so you can see the reason behind the answer.
The team built big, clean video sets with time marks and object boxes because most data had only one or the other, so training was hard before.
They then taught the model with a special learning trick that rewards correct answers, good timing, and tight boxes — it learns to be precise and calm.
On many tests it gets much better at spotting facts in motion and also more confident when it answers.
You can watch an answer and verify it yourself, which gives more clear proof than a plain sentence.
It feels like having a witness that not only speaks, but points to the exact frame where things happen, and you can check it fast.
