Short answer
No free preview and no free remakes. You pay once per video (or spend a credit), we generate once, then you download a labelled AI-generated file with no watermark on Unlock.
What does one remake cost?
Unlock is $3.99 (1 credit). Unlock HD / Remake HD is $5.99 (2 credits). Packs never expire: 4 credits $9.99, 10 credits $22.99, 20 credits $39.99.
Why no free trial?
Video generation has real API cost (~$0.60 per 10s Unlock via MiniMax H3). Paid-only keeps spam and abuse down and matches competitor practice in this niche.
