description: Per-dimension evaluation prompts, 1-5 scale (v2)
system_prompt: You are a strict video evaluation model.
general_keys:
- SA
- PTV
- persistence
eval_prompts:
  SA: |-
    You are evaluating a generated video on Prompt Alignment (SA).

    The text prompt used to generate this video is:
    "{prompt}"

    The video was generated using a text+image-to-video (ti2v) model, conditioned on the first frame and the text prompt above.

    Score SA (Prompt Alignment, 1-5):
    5=perfectly matches prompt, 4=clearly matches, 3=mostly matches, 2=clearly does not match well, 1=severely contradicts.
    Evaluate whether the depicted scene, objects, actions, and overall narrative correspond to the prompt description.

    Output ONLY a JSON object with exactly one key "SA" (integer 1-5). No other text.

    Example:
    {{"SA": 3}}
  PTV: |-
    You are evaluating a generated video on Temporal Coherence (PTV).

    The text prompt used to generate this video is:
    "{prompt}"

    The video was generated using a text+image-to-video (ti2v) model, conditioned on the first frame and the text prompt above.

    Score PTV (Temporal Coherence, 1-5):
    5=perfect temporal sequence, 4=correct order with minor timing issues, 3=mostly correct order, 2=significant misordering, 1=completely wrong temporal sequence.
    Evaluate whether event ordering is logically consistent (e.g., objects break before scattering, liquid is poured before it flows).

    Output ONLY a JSON object with exactly one key "PTV" (integer 1-5). No other text.

    Example:
    {{"PTV": 4}}
  persistence: |-
    You are evaluating a generated video on Object Persistence.

    The text prompt used to generate this video is:
    "{prompt}"

    The video was generated using a text+image-to-video (ti2v) model, conditioned on the first frame and the text prompt above.

    Score persistence (Object Persistence, 1-5):
    5=perfect object constancy, 4=near-perfect with trivial flicker, 3=minor inconsistencies, 2=noticeable persistence issues, 1=severe violations (objects appear/disappear/transform randomly).

    Output ONLY a JSON object with exactly one key "persistence" (integer 1-5). No other text.

    Example:
    {{"persistence": 4}}
training_prompts:
  SA: |-
    You are evaluating a generated video on Prompt Alignment (SA).

    Caption:
    "{prompt}"

    Evaluate whether the video content matches the caption, including scene, objects, actions, and relationships.

    Score 1-5:
    5=fully aligned
    4=mostly aligned with minor deviations
    3=partially aligned with notable gaps
    2=mostly misaligned
    1=not aligned

    Output ONLY a JSON object with exactly one key: SA.
  PTV: |-
    You are evaluating Temporal Coherence (PTV).

    Caption:
    "{prompt}"

    Evaluate whether the sequence of physical events follows a plausible temporal order.

    Score 1-5:
    5=fully plausible event order
    4=mostly plausible with minor issues
    3=partially plausible
    2=mostly implausible
    1=completely implausible order

    Output ONLY a JSON object with exactly one key: PTV.
  persistence: |-
    You are evaluating Object Persistence.

    Caption, for context only:
    "{prompt}"

    Evaluate whether objects maintain consistent existence, shape, and appearance throughout the video.

    Score 1-5:
    5=fully consistent
    4=mostly consistent with minor flicker
    3=noticeable issues
    2=major inconsistencies
    1=severe disappearance or identity changes

    Output ONLY a JSON object with exactly one key: persistence.
physical_sub_questions: false
physical_template: |-
  You are evaluating physical realism for one physical law: {law}.

  Criterion:
  {criteria}

  Caption, for context only:
  "{prompt}"
  {questions_block}
  Judge the video itself. Do not penalize prompt mismatch unless it affects whether this physical law can be evaluated.

  Score 1-5:
  5=clearly correct
  4=mostly correct with minor issues
  3=partially correct or ambiguous
  2=mostly incorrect
  1=severely incorrect

  Output ONLY a JSON object with exactly one key: {law}.
