Stabilisation Input — text-motion, Rotational roll
Rotational roll camera shake applied to the locked-off text-motion plate: up to 4.0 px of translation and 1.6° of roll at 8.0 Hz, seed 5162. Translation plus up to 1.6° of roll. Translation-only stabilisers cannot fix roll at all, so this immediately separates 2-DOF from full-affine implementations. Uncovered edges are filled black rather than padded, so the crop a stabiliser needs is visible in the input.

What is a .mp4 file?
MP4 (MPEG-4 Part 14) is a widely supported multimedia container based on ISOBMFF that holds video, audio, subtitles, and metadata, most commonly H.264 or H.265 video with AAC audio. It supports streaming, chapters, and multiple tracks. It is the dominant format for distributing and playing digital video.
How to use this file
Use an example MP4 to test container demuxing, track and codec detection, seeking and streaming, and transcoding or thumbnail-extraction pipelines.
How to use this file for testing
“Stabilisation Input — text-motion, Rotational roll” is a deterministic Novus Examples fixture for Video stabilisation, Video QA. Camera shake applied with a recorded motion path over a static original, so a stabiliser's residual motion can be measured rather than estimated.
Documented properties for this file: seed 5162 · stabilisation input · 24 fps. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Media fixtures are short and synthetic by design. Prefer waveform or transcript ground truth in the same group when measuring ASR, trim, upscale, or sync tools; do not assume broadcast-quality masters.

- mp4Stabilisation Ground Truth — detail-chart, Locked OffThe locked-off reference for the detail-chart stabilisation set — any motion in this clip is subject motion, not camera motion. The shaky clips in this group are this footage with a recorded synthetic camera path applied, so residual motion after stabilisation can be measured against zero rather than eyeballed.
- mp4Stabilisation Ground Truth — pan-city, Locked OffThe locked-off reference for the pan-city stabilisation set — any motion in this clip is subject motion, not camera motion. The shaky clips in this group are this footage with a recorded synthetic camera path applied, so residual motion after stabilisation can be measured against zero rather than eyeballed.
- mp4Stabilisation Input — detail-chart, Heavy handheldHeavy handheld camera shake applied to the locked-off detail-chart plate: up to 12.0 px of translation at 6.5 Hz, seed 5131. Twelve-pixel excursions at a slower, larger cadence: running, or a long lens. Requires real trajectory smoothing rather than frame-to-frame alignment. Uncovered edges are filled black rather than padded, so the crop a stabiliser needs is visible in the input.
- mp4Stabilisation Input — detail-chart, High-frequency jitterHigh-frequency jitter camera shake applied to the locked-off detail-chart plate: up to 2.5 px of translation and 0.5° of roll at 23.0 Hz, seed 5193. Small, fast jitter near the frame rate — vibration from a vehicle or a drone motor. Aliases against the sampling rate, so naive low-pass smoothing of the path leaves it almost untouched. Uncovered edges are filled black rather than padded, so the crop a stabiliser needs is visible in the input.
- mp4Stabilisation Input — detail-chart, Light handheldLight handheld camera shake applied to the locked-off detail-chart plate: up to 3.0 px of translation at 11.0 Hz, seed 5100. Sub-pixel-to-3-pixel translation at walking cadence — the residual wobble left after in-body stabilisation. Easy to correct, and the case where over-correction visibly crops the frame for nothing. Uncovered edges are filled black rather than padded, so the crop a stabiliser needs is visible in the input.
