QastX for marketers: short-form clips at the speed of your content calendar
Stop briefing one-clip-a-week edits. Drop your webinar, founder interview or long product video and ship 10+ on-brand vertical clips ready for paid and organic.
Performance teams know the bottleneck isn't ad spend — it's creative. You need 5–10 fresh hooks every week to keep CPMs sane. QastX turns long-form assets you already have (founder talks, webinars, customer interviews, product demos) into a stack of vertical clips with subtitles. Test more hooks, kill the losers, scale the winners. No more waiting four days on an external editor for one variant.
How QastX helps
Your paid social fatigues fast and you can't ship enough creative variations to keep CPMs down.
Take last quarter's webinar or founder interview and run it through QastX → 10+ on-brand vertical clips.
Result: 5–10× more creative variants per week without a bigger editing team.
Your founder records great interviews but the team can't repurpose them fast enough.
AI pulls the strongest soundbites and exports them with auto-subtitles in your brand caption style.
Result: Same week the interview airs, you have a content pipeline for the next 30 days.
You manage social for multiple brands and each one needs daily short-form content.
One operator processes long videos in QastX for every brand — AI does the cutting, you do the QA.
Result: Multi-brand content factory without 10 freelance editors.
