Asset video total pixels (W×H) must be in [409600, 927408],

Error message

Asset video total pixels (W×H) must be in [409600, 927408], got {pixels:,} ({w}x{h}).

What it means

Asset videos must have a total pixel count between 409,600 (640x640 equivalent) and 927,408 pixels, enforced after the aspect-ratio check in the Create Seedance Asset video node. This is effectively a resolution window (roughly 720p-class) that the provider accepts for reusable reference assets; out-of-window videos are rejected before upload.

Solutions

Resize the video so total pixels land in [409600, 927408], e.g. scale 1080p down to ~1280x704 (901,120 px).
Upscale very small clips above the 409,600 px floor before upload.

Defensive patterns

Strategy: validation

Validate before calling

w, h = video.get_dimensions()
if not (409_600 <= w * h <= 927_408):
    raise ValueError("resize so total pixels are in [409600, 927408]")

Prevention

Downscale 1080p-class clips to ~1280x704 before upload.
Upscale tiny clips above the 409,600 px floor; the 300-6000px dimension check alone is not sufficient.

When it happens

Trigger: Uploading a 1920x1080 clip (2,073,600 px > cap) or a 512x512 clip (262,144 px < floor) to the video asset creation node.

Common situations: Reusing full-HD source footage as a reference asset; small upscaled thumbnails falling under the floor; assuming any 300-6000px dimension video is acceptable because the dimension check passed.
