Quick Links


How It Works

Step 1 → Paste a YouTube link or upload a video file
Step 2 → Choose your settings (or leave everything on Auto)
Step 3 → Hit "Start Processing" → your hour-long video becomes 5–10 perfect shorts in under 2 minutes
Step 4 → Download any format (9:16, 16:9, 1:1, 4:5, 2:3) in up to 4K — unlimited times, zero extra cost

That's it. No queues. No waiting. No hidden fees.


Credits & Pricing

QuestionAnswer
How many credits does a video cost?1 credit = 1 minute of trimmed video (rounded down, minimum 1). Example: 90-min video using only 10–40 min timeframe = 30 credits.
What is FREE forever?Unlimited downloads & 4K exports for active projects. Infinite clip generation, aspect ratio changes, caption edits, face tracking, emoji overlays — everything after the first processing is 100% free.
Do credits expire?Never. Top-up packs and monthly credits never expire.
Can I get more than 30 credits on Free plan?No. Free plan is capped at 30 minutes/month. Upgrade to Starter (600 min) or Agency (3000 min).
What happens if I run out?You'll see an "Insufficient Credits" modal with one-click upgrade options.

No thumbnail showingFixed in latest update — now uses sddefault.jpg fallback. Refresh the page.
"Insufficient credits" errorGo to Dashboard → Credits → buy a pack or upgrade plan
