What 1,000 credits buy
1,000 credits is $4.00. At the cheapest listed rate that is about 111 seconds at 540p on Vidu Q4 and about 28 seconds at 720p on Kling 4.0; at the dearest listed rate, about 12 seconds at 4k and about 18 seconds at 1080p. The Lite plan's 800 credits a month are four fifths of that.
A brief written for each
The studio's scene writer works in timed beats with a camera plan and an audio line, and these two briefs are shaped the same way. Paste either into Mint Studio with the model chosen and the price appears on the button.
Vidu Q4
From the uploaded portrait: the man looks up from his book, smiles and says "you came back" at 4 s, rain against the window behind him. 8 seconds, 4K, audio on.
Kling 4.0
A 20-second shot from the same portrait as the first frame: the camera pulls back from his face to reveal the whole library, ending on a wide frame of the rain-streaked window. 1080p.
Using both in one project
Open with Vidu Q4 so the portrait speaks its first line in 4K, then follow with a long Kling 4.0 pull-back that ends where you want. Lay the music under both in Video Edit and share the reel everywhere at once.
Try both on one plan
Same prompt, both models, prices on the button. Lite is $9.99 a month for 800 credits with every AI model, Vidu Q4 and Kling 4.0 included; Private Studio is $999 a month for 110,000 credits with no restrictions. What the credits buy: Vidu Q4 · Kling 4.0.
$999 a month, or $9,990 a year, for 110,000 credits every month (about 1,833 ten-second clips), up to 10 creations at a time on every Wan and Seedream model, in a private studio linked to your reel-mint.com account.
