Kuis Pengeditan Satu Pemotretan Tune-A-Video

Jawaban dan penjelasan muncul saat Anda mengikuti kuis.

1. Model dasar apa yang digunakan Tune-A-Video sebelum mengadaptasinya untuk video?
   • Model difusi teks-ke-gambar yang telah dilatih sebelumnya seperti Difusi Stabil
   • Model bahasa yang besar
   • Model video yang dilatih dari awal pada jutaan klip
   • Generator gambar berbasis GAN
2. Apa yang dimaksud dengan 'one-shot' di Tune-A-Video?
   • Menghasilkan dalam satu langkah denoising
   • Menyetel hanya pada satu video sumber
   • Menggunakan satu prompt untuk seluruh kumpulan data
   • Berjalan pada satu 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. Selama penyetelan, apa yang terutama diperbarui oleh Tune-A-Video agar tetap efisien?
   • Seperangkat kecil parameter perhatian/temporal
   • Setiap bobot dalam model lengkap
   • Hanya kosakata encoder teks
   • Dekoder gambar saja
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
