Turn your StreamYard recordings into content

Turn any StreamYard recording into finished content. Upload the replay and Castmagic transcribes it, then drafts the recap newsletter, blog post, social clips, and follow-up email in minutes.

The stream happened live once. The replay never moves.

A live show, a webinar, an interview — it went out once, in real time, to whoever could make it. Then the recording lands in a folder and the momentum dies. Turning that replay into a recap, a blog post, the clips, and the follow-up email means re-watching an hour you already sat through and writing each piece from a blank page.

Castmagic turns the replay into the rest of the funnel. Drop the recording in and it comes back transcribed with speaker labels and timestamps, then drafted into a recap newsletter, a blog post, social clips, and a follow-up email — so the people who missed it live still get the value, and the people who showed up get a reason to come back.

Capture what was said live, exactly

Live shows wander — Q&A, tangents, the one offhand line that turns out to be the whole point. Castmagic transcribes the full replay at ~95%+ accuracy on clear audio, with timestamps so you can jump straight to the moments worth pulling and speaker labels so panels and interviews stay attributed.

Add custom vocabulary for product names and guest names so the recap gets them right, in any of 60+ languages with automatic detection.

Feed the follow-up, not just the archive

The replay is the easy part — the value is in everything that comes after the broadcast. From one StreamYard recording, Castmagic drafts the recap newsletter for no-shows, the blog post that ranks long after the stream, the social clips that pull people to the next one, and the follow-up email that closes the loop.

Save your recap structure as a recurring prompt and every future stream comes back in the same format, so post-show turnaround becomes routine instead of a project.

Drafted from the broadcast, edited by you

Because Castmagic works from the verbatim transcript, the quotes and takeaways are things that were actually said on the stream — not a model guessing at what happened. You stay the editor: confirm the angle, add registration or replay links, and send.

Running a whole series or a season of webinars? Connect your library to Claude at castmagic.io/claude and work across every episode at once to spot recurring themes and resurface the best moments.

How to repurpose a StreamYard recording

Export your StreamYard recording and drop it in

Download the recording, then drag the file straight into the uploader above. Audio or video both work — Castmagic transcribes the spoken track either way. No link needed; the file is all it takes.

Castmagic transcribes it

Transcription runs in minutes — 60+ languages with auto-detect, speaker labels, and word-level timestamps — so the draft is built from exactly what was said, not a rough summary.

Draft your content

Pick the content preset, or write your own prompt, and Castmagic drafts it from the recording — structured and ready to edit in your voice, not a wall of transcript.

Make it yours

Refine the draft in the editor: sharpen the hook, adjust the tone, and drop in your links and CTA. Save the prompt as a recurring step so every future episode comes out the same way.

Frequently Asked Questions

Last updated June 2026 by the Castmagic team

How do I turn a StreamYard recording into content?

Export the recording and drag it into Castmagic — it transcribes in minutes. Then choose the content preset (or your own prompt) and Castmagic drafts it from the recording, in your voice. Edit it, drop in your links, and publish. The whole loop takes a few minutes instead of an afternoon.

Will the content sound like me?

Yes — that's the point. Castmagic drafts from your actual words, and you can give it a custom prompt with your tone, structure, and rules (no hashtags, short sentences, your sign-off). Save it as a recurring prompt and every episode comes out on-brand. You stay the editor; it removes the blank page.

Can I repurpose my whole back-catalog at once?

For a single recording, the Castmagic app is the fastest path. When you want to work across your entire library at once — a lead magnet from your best episodes, a book, a course — connect Castmagic to Claude with the MCP connector and Claude can search and build from every recording you have. See castmagic.io/claude.

How accurate is the transcription it builds from?

Castmagic uses state-of-the-art speech models with 60+ languages, automatic language detection, and speaker labeling. Clear audio typically transcribes well above 95% accuracy, and a custom-vocabulary list keeps names, products, and jargon spelled right — so the content is built on a clean source.

Is it free to try?

Castmagic has a free tier so you can run a StreamYard recording through the full workflow and see the output. Higher volume — more recordings per week, longer files, and unlimited content generation — is on the paid plans.

Where do I get the file from StreamYard?

Download the recording from your StreamYard dashboard after the broadcast, then drag it into the uploader above. The local recording works best, but any clean export of the stream transcribes the same way.

Can it handle a long webinar or multi-guest live show?

Yes. Multi-hour streams and panels are fine — Castmagic applies speaker labels so each host and guest is separated, and timestamps make it easy to find the segments worth clipping.

I only have the audio, not the video — does that work?

Yes. Castmagic transcribes the spoken track whether you upload audio or video, so an audio-only export of your StreamYard recording is enough to draft every format.
