Review
Visual explanation finding
Relevant imagery appears, but it mostly repeats the narration instead of showing how the concept works. The public output is reviewable, but no blinded multi-reviewer sheet exists.
Review status: provisional manual. See the visual-scoring rubric →
What can be checked
The public page proves the output title, date, duration, playable video, summary, and transcript. It does not reveal which HeyGen workflow made the video or how many credits it consumed. The overall rank therefore uses the published Creator subscription calculation rather than an observed test charge.
Published Creator speed tier
HeyGen's pricing table lists the Creator monthly plan at $29 with 600 monthly credits, videos up to 30 minutes, 1080p export, and Faster processing. The test record does not prove that this sample used Creator or the Faster tier, so the label is plan context rather than a measured test setting.

Price record
Pricing basis
The ranking uses the published Creator monthly plan: $29 ÷ 600 credits × 20 Video Agent credits per prompted minute = $0.9667, shown as $0.97. The plan includes videos up to 30 minutes, 1080p export, Faster processing, unlimited Photo Avatars, watermark removal, voice cloning, advanced image and video models, 175+ languages and dialects, and one-month credit rollover. This is subscription amortization, not the observed test charge.
