+## VIDEO
+Frames: one frame per second of the timeline, at most 512 frames per item (uniform thinning beyond; the videos are
+stored at no more than 2 frames per second and 1,024 frames), each frame resized to short side 224. When a model
+rejects the request for its size the frame count is halved and the request repeated; the number of frames sent is
+recorded per item.
 
 Prompt (frames first, then the text):
-    These are {n} frames sampled from a video, in order. Answer the multiple-choice question about the video.
+
+    You are given {n} frame(s) sampled from a video. Answer the question based on these frames.
+
     Question: {question}
-    Options:
     A. ...
     B. ...
-    Answer with the option's letter from the given choices directly.
+    Reply with ONLY the option letter (or the exact short answer if no options).
 
 ## BLIND
-Question and options only, no frames; four option permutations per item (seed 42, exp/analysis/meta/meta_runner.py
-permutations_for); the blind score is the mean over the four permutations.
+Question and options only, no frames; four option permutations per item, fixed by
+random.Random("42|<item_id>").sample(range(k), k); the blind score is the mean over the four permutations.
+
+    You are given NO frames from the video. Answer the question from the text alone.

 ## Scoring
-The rule scorer of the paper (exp/pipeline/scoring.py, mode "list"): the first option letter in the reply, or the option
-whose text the reply repeats; a reply that names no option is wrong. Gain = VIDEO - BLIND on the same items.
+Rule scorer (video_index/scoring.py): the leading option letter of the reply, a stated answer ("the answer is B"),
+or the option whose text the reply repeats; a reply that names no option is wrong. Gain = VIDEO - BLIND on the same items.
