collision/00005672.mp4	The video captures a high-velocity ballistic impact and penetration event. On the left, a metallic firearm barrel, part of a heavy, stationary shooting rig, fires a projectile horizontally toward the right. The target is a circular, disc-shaped plate mounted vertically on a wooden support. The face of the plate is cove...	collision
collision/00005695.mp4	The video captures a progressive structural collapse of a large, cylindrical tower built from interlocking plastic blocks, triggered by a domino chain reaction. The tower is a hollow, multi-layered ring composed of rigid, rectangular plastic pieces in black, magenta, purple, teal, and yellow, arranged in a grid that re...	collision
collision/00005712.mp4	The video captures a high-speed fluid impact and splashing event, where a dense, viscous red liquid collides with a shallow pool of opaque white liquid on a flat surface. The core physical process is an inelastic collision followed by radial ejection and surface-tension-driven retraction. The red fluid is thick and glo...	collision
collision/00005723.mp4	The video captures a high-speed projectile impact and the resulting impulsive displacement of a suspended assembly. A large, flat, circular brass gong is mounted vertically within a red-painted wooden frame, which rests on a black metal stand. The gong is a thin sheet of a dense, relatively soft metal alloy, giving it ...	collision

WISA I2V Test Suite (121 frames @ 24 fps)

A human-free physics video test set of 5,638 clips across 11 physical-phenomenon categories, re-cut to 121 frames @ 24 fps at 832x480, paired with the first frame of every clip (PNG) so the set can be used directly as an image-to-video (I2V) benchmark.

Each clip ships with a long-form English prompt describing the scene and its physics.

                        plus per-category prompts.txt, ids.txt, metadata.csv

The archives are uncompressed tar on purpose: MP4 and PNG are already compressed, and gzip/zstd recover under 2% while making the files slower to read.

Download

Whole suite:

hf download csusupergear/wisa_i2v_testsuit --repo-type dataset --local-dir wisa_i2v_testsuit
cd wisa_i2v_testsuit
for f in videos/*.tar; do tar -xf "$f" -C videos/; done
for f in frames/*.tar; do tar -xf "$f" -C frames/; done

A single category (e.g. collision):

hf download csusupergear/wisa_i2v_testsuit --repo-type dataset \
  --include "videos/collision.tar" "frames/collision.tar" --local-dir .
tar -xf videos/collision.tar -C videos/
tar -xf frames/collision.tar -C frames/

After extraction the layout is videos/<category>/<id>.mp4 and frames/<category>/<id>_frame0.png, so an I2V pair is (frames/<category>/<id>_frame0.png, prompt) with videos/<category>/<id>.mp4 as the reference.

Notes on the re-cut

This is the same test set as the earlier 81-frame/16 fps release -- same clip ids, same categories, same prompts, same ordering. Only the video files differ: they are re-cut from the raw archives rather than resampled from the 16 fps clips, because 16 fps had already discarded the intermediate frames that 24 fps needs.

121/24 = 5.0417 s is marginally shorter than the old 81/16 = 5.0625 s, so this is a temporal-resolution upgrade rather than a longer window. The cut reuses the original start offset, start = (duration - 81/16) / 2, which keeps the new clips frame-aligned with the old ones:

new frame 3k  ==  old frame 2k

Verified on high-motion clips: MAE 2.1-2.4 at the matched index vs 11-17 at neighbouring indices. 5 of the 5,638 source clips have a native fps below 24; there were no re-cut failures.

Prompts are unchanged. They remain valid for the re-cut: the captioner subsamples to 4 fps, which lands on the identical 21 timestamps (0.00, 0.25, ... 5.00 s) in both the old and the new clips.

Ordering guarantee

Clips are sorted by ascending id within each category, so line i of a category's prompts.txt is the prompt for line i of its ids.txt.
