Colossyan vs StrokeVideo

Colossyan has no write-up on Specifiction yet; its figures are above.

StrokeVideo turns a topic, script, recording, web page or PDF into a narrated whiteboard explainer video downloadable as an MP4. It draws each storyboard board as a complete image, then traces the strokes in time with narration. The service lists 23 drawing styles and narration in 14 languages. Videos can run from 30 seconds to about 15 minutes, while the free daily video is limited to two minutes. Editing means changing the script, storyboard or board timing and rendering again; frame-level edits require another editor and the downloaded MP4. The free plan costs nothing, gives one video daily, no watermark and all styles, with credits expiring that day. Monthly membership costs $19.90 a month; yearly costs $99.90 a year. Free-account videos remain seven days; membership keeps them three months. Commercial use is supported, and the maker names teachers, faceless YouTube channels, marketers and workplace trainers.
