How to benchmark AI video for fabric
The fairest way to compare AI video engines for fashion is one reference image, one prompt and five difficult fabrics, scored on the same six-point rubric. Here is the full method so any brand can repeat it.
The five test fabrics
| Fabric | What to watch | Typical failure |
|---|---|---|
| Silk charmeuse | Liquid drape, specular highlights, no stiff folds | Sheen flickers between frames; folds behave like paper |
| Raw denim | Weight, twill texture, seam and rivet placement | Texture smears into flat blue; topstitching drifts |
| Sheer organza | Transparency, layered edges, light passing through | Becomes opaque or merges with skin and background |
| Chunky knitwear | Stitch pattern stays fixed, soft stretch | Cable pattern crawls or re-draws every frame |
| Printed pattern | Print stays locked to the garment as it moves | Print slides, warps or changes scale |
Scoring rubric (30 points)
0–5
Garment fidelity
Matches the reference: cut, colour, details
0–5
Texture stability
Fabric texture holds across all frames
0–5
Drape physics
Moves according to weight and material
0–5
Seams & construction
Seams, buttons, hems stay in place
0–5
Pattern lock
Prints and knits don't crawl
0–5
Body interaction
No fabric clipping through limbs
Test protocol
- Shoot or pick one sharp, evenly lit reference image per fabric.
- Use the identical prompt below in every engine; only fill the brackets.
- Generate three clips per engine and fabric; score the median clip.
- Watch at full size and at 0.25× speed; pause on the first, middle and last frame.
- Record the engine version and date — results change with model updates.
[Model] wearing [garment] in [fabric], same garment as reference. Slow walk toward camera, gentle breeze, [camera move]. Fabric moves naturally according to its weight. Keep seams, print and colour unchanged. Soft studio light, plain [colour] background, 5 seconds.
Run the test in the Motion Studio (pay as you go) and compare camera moves in which camera moves keep clothes accurate.
Questions
- Which AI video tool is best for silk and other fluid fabrics?
- It changes with every model update. Run the same reference image and prompt through each engine and score them with the rubric on this page.
- Why does fabric texture flicker in AI video?
- Video models regenerate detail every frame. Fine texture and prints are hard to keep stable, especially with fast motion.
- How do I reduce garment distortion in AI video?
- Use a sharp reference, slow camera moves, short clips, simple backgrounds and a prompt describing the fabric weight.
- Are these benchmark results?
- No. This page is a repeatable test method. We publish scores only from tests we have actually run.
