Tune-A-Video One-Shot Editing Quiz

Answers and explanations appear as you take the quiz.

1. What base model does Tune-A-Video start from before adapting it for video?
   • A pretrained text-to-image diffusion model like Stable Diffusion
   • A large language model
   • A video model trained from scratch on millions of clips
   • A GAN-based image generator
2. What does 'one-shot' refer to in Tune-A-Video?
   • Generating in a single denoising step
   • Tuning on just one source video
   • Using one prompt for the whole dataset
   • Running on a single GPU
3. How does Tune-A-Video’s sparse causal attention connect video frames?
   • Frames are generated fully independently
   • Every frame is averaged into one image
   • Each frame can attend to the first frame and the preceding frame
   • Attention is disabled across all frames
4. What does DDIM inversion provide before Tune-A-Video samples an edit?
   • A compressed audio track
   • A new video caption
   • A camera calibration file
   • A source-conditioned latent that guides generation from the input video
5. During tuning, what does Tune-A-Video primarily update to stay efficient?
   • A small set of attention/temporal parameters
   • Every weight in the full model
   • Only the text encoder vocabulary
   • The image decoder only
6. What limitation motivated later tuning-free video-editing methods?
   • It can only edit audio
   • Tune-A-Video requires per-video tuning before editing a new clip
   • It supports no text prompt
   • It was trained only on black-and-white images
7. Which editing capability did the Tune-A-Video paper demonstrate?
   • Automatic speech-quality scoring
   • 3D camera-pose recovery from photos
   • Text-guided style transfer on a source video
   • Instrument-stem separation
8. Which content change can Tune-A-Video apply to a source clip using text?
   • Measuring packet latency
   • Estimating pitch from a monophonic signal
   • Recovering 3D scene geometry from uncalibrated photos
   • Changing a subject or background while trying to retain source motion
