Castmagic and Opus Clip both repurpose long-form audio and video into shorter content, but they take different approaches. Opus Clip is optimised for video clip extraction - it identifies the most engaging moments in a video and reformats them into vertical short-form clips for TikTok, Instagram Reels, and YouTube Shorts. Castmagic is optimised for written content extraction - it takes audio or video and generates transcripts, show notes, newsletters, social captions, and blog outlines from the same recording. For video creators focused on social media clip distribution, Opus Clip is the stronger choice. For podcast producers and content teams who need written output from their recordings, Castmagic delivers more value.

Frequently asked
Can I use both together?
Yes - many podcasters do. Castmagic handles the podcast-to-text-content workflow; Opus Clip handles podcast-to-shorts on YouTube/TikTok. Combined cost ~$60/mo replaces a $2-3K/mo content team.
Does Opus Clip work for podcast video?
Yes. If you record video alongside audio (Riverside, StreamYard, Zoom), upload to Opus Clip and it extracts vertical clips. Audio-only podcasts work less well since visual context is missing.
Which has better captions?
Both ship strong auto-captions. Opus Clip captions are more visually polished out of the box (animated, branded). Castmagic transcripts are more accurate for text-content use but less visually styled.
Is there a free tier?
Both have limited free tiers. Castmagic free tier covers a few episodes; Opus Clip free tier covers ~60 minutes of upload per month. Both are usable for testing before committing.
