Question B7-003

A team has a finished Sora 2 (preview) clip. The client now wants three changes: a warmer color palette, a red car instead of a blue one, and an orbiting camera. Which approach follows the remix guidance?

Select one answer.

  • A Remix the video while its job is still in_progress so the changes are applied before rendering finishes
  • B Download the MP4 and pass it as input_reference with a prompt that lists the three changes
  • C Send one remix prompt that lists all three changes so the edits stay consistent with each other
  • D Remix the completed video by its video ID with a prompt that makes one clearly described change, then remix again for each further change ✓ Correct answer

Answer: D

Remix references the ID of a successfully completed video plus an updated prompt, and keeps the original framework, scene transitions and layout. Microsoft recommends one clearly articulated adjustment per remix, because narrow edits keep more fidelity and cause fewer visual defects. input_reference is a single reference image used as the first frame, not a finished MP4.

Deep dive

How it works

Remix in Sora 2 (preview) modifies specific aspects of an existing video while keeping its core elements. Instead of regenerating from scratch:

  1. Reference the video ID of a successfully completed generation.
  2. Supply an updated prompt that describes the change.
  3. The system keeps the original video's framework, scene transitions and visual layout, and applies the change.

The guidance on how much to change at once is explicit: limit each remix to one clearly articulated adjustment. Narrow, precise edits keep more fidelity to the source and are less likely to produce visual defects.

So the three client requests become a chain:

  1. Remix the original: warmer color palette.
  2. Remix that result: replace the blue car with a red one.
  3. Remix that result: an orbiting camera move.

Check each output before the next step. If one edit goes wrong, you only redo that step.

The other options, and when you'd use them

  • Remix while the job is in_progress: Remix references a successfully completed generation. Wait for the job to complete.
  • Pass the MP4 as input_reference: input_reference is a single reference image used as the first frame, not a video.
  • One prompt with all three changes: The guidance is one clearly articulated adjustment per remix; stacking changes risks lower fidelity and visual defects.

Exam tip

Sora 2 remix = completed video ID + updated prompt + one change per remix. Several changes = several remixes in sequence.
