The script is the atom, the video is one rendering of it
Most repurposing advice is really re-uploading: take the MP4, strip the watermark, post it to Reels and Shorts. That works, and it is also the least valuable half of the opportunity, because it only reaches the platforms that accept vertical video. The other half is the text, which reaches every platform that does not. Once the clip is a Markdown transcript, one 45 second video becomes a LinkedIn post, an X thread, an Instagram caption, a YouTube description, a newsletter section and a paragraph of a blog article, and none of them read like a repost because none of them are.
What each destination actually needs
The edits are small and they are different every time. LinkedIn allows 3,000 characters and rewards a first line that works before the "see more" cut, so lead with the transcript's hook and keep the payoff below the fold. X wants the transcript split at its natural argument breaks, one idea per post, with the 280 character limit deciding where to cut. Instagram captions run to 2,200 characters and read better as a condensed version than a full script. YouTube descriptions allow 5,000 characters, so the near-full transcript fits and doubles as searchable text under the Short.
For the long-tail destinations, see the dedicated pages: newsletter, blog post, and subtitles when the reupload needs its own caption file.
The practical rhythm
Convert one link at a time. This is a web tool with no bulk queue, no API and no scheduled job, so the honest workflow is a batch session: open TikTok Transcript, run the week's clips through it back to back, download each .md, then write from the folder. Ten clips takes a few minutes of clicking and 20 credits. Long-form sources join the same folder via YouTube to Markdown and Video to Markdown. The strategy behind the loop is laid out in transcribing TikToks for repurposing.
