  1. A system says an event occurred somewhere in a clip. What additional output does temporal localization require?
    • Only a longer category description
    • Approximate start and end times for the event
    • Only a frame-level object name
    • Only a video file checksum
  2. A video is sampled every five seconds. A brief event occurs only from 3.1 to 3.4 seconds. What follows?
    • The event must appear at the five-second frame
    • The clip cannot contain audio
    • The model knows the event from a neighboring frame
    • The sampled frames can miss the event entirely
  3. Why does “not seen in sampled frames” fail to prove an event never happened?
    • Unobserved intervals may contain the event
    • Absence in samples is a full-video proof
    • Every frame has identical content
    • Sampling adds missing audio evidence
  4. A system identifies a cup and a table but reverses which action came first. Which ability failed?
    • Object recognition only
    • Video compression quality
    • Temporal ordering of events
    • The presence of a cup
  5. How can an audio track help a video analysis while also introducing uncertainty?
    • Audio always proves visual intention
    • Audio eliminates the need to inspect frames
    • A transcript is a guaranteed record of every sound
    • It supplies sound context, but transcripts can omit or misattribute speech
  6. A model describes a person’s intention from one observed action. What should a reviewer distinguish?
    • Frame rate from file format
    • Visible evidence from inferred mental state
    • Video duration from timestamp
    • Visual objects from subtitles only
  7. Which material helps verify a video-summary claim?
    • Only a fluent summary sentence
    • Only the model’s confidence adjective
    • The original clip and linked time range
    • Only an unrelated thumbnail
  8. Why test long videos and camera cuts rather than only short demos?
    • They can introduce errors absent from curated short clips
    • Long clips always make models more accurate
    • Cuts supply guaranteed event boundaries
    • Demos are identical to real capture
