What AI video really costs after failed and unusable footage
List price counts generations. Video Labs counts accepted clips and usable seconds. We run fixed prompts repeatedly, preserve billing and latency evidence, and grade artifacts separately from instruction following.

First measured result
CogVideoX-3 needed 29% more budget than clean per-second math
Z.ai's official $0.20 per-video rate works out to $0.0400 per requested second for this five-second setup. One billed request was not retrievable and four sampled seconds failed the usability rule, raising the observed cost to $0.0516 per accepted second.

Every provider faces the same buyer-focused accounting
01 · Repeat
Multiple attempts
We repeat each prompt and modality so a single lucky clip cannot decide the verdict.
02 · Preserve
Billing + outputs
Request state, task IDs, latency, output hashes, failures, and observed billing are retained.
03 · Grade
Usable footage
Prompt adherence, temporal consistency, text accuracy, and severe artifacts are scored separately.
04 · Normalize
Accepted-output cost
We report cost per accepted clip and usable second, including billed failures and rejected footage.
Next: larger Z.ai benchmark wave
More generation stress tests plus video-understanding checks
The next runs stay on earned Z.ai bonus credit: a larger CogVideoX-3 prompt set for motion, camera control, exact text, and repeatability, followed by timestamped video-understanding tasks. Results will appear here only after billing evidence, outputs, grading, maintained official price sources, and independent verification are complete.
