What costs money, and what does not
Making a picture move costs a page load. Making a file costs our hardware, and that is the line.
Free, with no account
Every style page, the live preview, the microphone visualiser, and dropping your own track in to watch it react. Free exports are watermarked, up to thirty seconds, at 720p.
Music — $14 a month
Clean renders at full length and 1080p or better, sixty render-minutes a month, saved projects, stems, 360 mode, and publishing to your own YouTube channel.
Metered by the second, not by the video
A thirty-second loop and an eight-minute film are not the same purchase. The plan buys an allowance of render-seconds; anything past it draws on the shared token wallet.
Questions
Is Music included in Starter, Pro or Unlimited?
Yes. Every Leumas plan from Starter upwards includes it, so nobody on a platform plan ever buys it twice. The standalone $14 row exists for somebody who wants only this.
What happens if a render fails?
You are not charged for it. A render is only billed once it has produced a file, and a file with no audio stream is rejected before it is offered to you or charged for.
