How can I split a transcription into multiple paragraphs?

Just for fun I decided to create an application assisted by Open-AI that takes a video and turns it into a readable article. I have used the audio/transcriptions endpoint to transcribe the video, and the chat/completions endpoint to generate a header for the article. My issue is that almost the entire transcription is a solid chunk of text. It added linebreaks in the beginning, but then it’s just a solid chunk. You can see the transcription here: Open AI transcription -

How can I use open AI to fix this? Can I tweak the audio/transcriptions call somehow? Can I use some other endpoint to insert linebreaks?
