Answers and explanations appear as you take the quiz.

1. What most distinguishes video-to-audio models from text-to-sound-effect tools?
   • They only generate music
   • They use the footage itself to match sound to on-screen events and timing
   • They require recorded microphone input
   • They cannot accept any text prompt
2. The film craft of Foley is named after whom?
   • Jack Foley of Universal
   • A sound effects software company
   • A microphone brand
   • A film festival
3. Which system generated video and audio together rather than adding sound afterwards?
   • VGGSound
   • Synchformer
   • CLIP
   • Google's Veo 3
4. What role does an optional text prompt play in a V2A model?
   • It replaces the video entirely
   • It sets the video frame rate
   • It adds details pixels cannot supply, such as the surface material
   • It translates dialogue
5. Why might a V2A model make a plastic prop sound metallic?
   • It cannot reliably infer material from appearance alone
   • The video codec distorts sound
   • Plastic cannot be recorded
   • The model only produces metal sounds
6. What is VGGSound?
   • A mixing plugin
   • A synchronization metric
   • A dataset built from YouTube video clips with sound
   • A Google audio model
7. What does MMAudio pair with lower-rate semantic image features to improve timing?
   • Lyrics transcriptions
   • Higher-rate synchronization features from a Synchformer model
   • MIDI note data
   • Random noise only
8. How is V2A output best treated in professional sound work?
   • As a final mix ready for release
   • As a replacement for all recorded effects
   • As unusable
   • As a first pass that a sound editor refines
