From $15 a month.

Yes. Sign up free, no credit card, and every plan and per-second rate is public before you pick one. When a signup credit is on, you can see the first section of your first riff before you pay. A riff short enough for one section comes whole.

Yes, right from Settings, no email needed. You keep your plan to the end of the period you've paid for and aren't charged again.

One finished 15-second video. Some tools count a 5 to 8 second clip as one video, so the same credits read as fewer videos here, but each one is a full 15-second video. Billing is still per second at the engine's rate (Seedance 2.0 Fast 480p 40 credits/s · 720p 80/s · Seedance 2.0 480p 50/s · 720p 100/s · 1080p 250/s · Seedance 2.5 480p 75/s · 720p 150/s · MiniMax H3 768P 40/s · 2K 80/s), so a 9-second riff bills 9 seconds and a 30-second riff about two videos' worth. It's a way to count, not a length cap. MiniMax H3 also bills each reference image beyond 5 in one render: 16 credits at 768P, 20 at 2K.

Yes, and the range on each plan card shows exactly that. The small number is what the default engine makes, the big one what the cheapest engine makes, both at a similar 720p-class picture; only the rate differs. Rates don't follow pixel count: at the same 720p-class picture, engines run from 40 to 150 credits a second. A higher resolution costs more per video and lands below the range. Every engine and resolution is open on every plan, nothing is locked behind a higher tier, and the exact rate shows in the app before you render.

Credits refresh monthly and don't roll over: pick the tier that matches your posting cadence.

Upgrade in one click on the same billing interval: the extra credits land instantly, prorated. Already on Studio? Email [email protected] with your monthly volume and we'll size a plan around it.

You pay only for successfully generated video seconds. A run that produces no video costs nothing; if you cancel partway or a late stage fails, only the seconds already rendered are billed.

Not as pay-as-you-go yet, but the plan already works close to it: you're billed only for successfully rendered seconds, your credits refresh each month, you can upgrade mid-month, and you can cancel at the end of any period.

Securely through Stripe, with Visa, Mastercard and other major cards. Prices are in USD, excluding tax; where tax applies, it is calculated at checkout from your billing address.

Yes, everything you make is yours to post, run as ads, and monetize, with no extra license or revenue share from us. That is the part freelance UGC rate cards usually price separately: paid-ads usage is often an extra 50-100% on top of the creator fee, on a 3-6 month term. We add no usage term or platform limit to a riff. What comes from someone else isn’t ours to give: music from a source video (its rights stay with its owner, so check you’re cleared to use it where you post), and, in a Swap, what it keeps from the source, such as the person when you don’t pick a character, the voices that don’t change, and a template’s music, voices and people, which aren’t rights-cleared.

Yes. Reframe any finished video into 3:4, 1:1 or 4:5: near frame-identical, only the framing shifts. Each ratio is its own render, billed per second at the reframe rate, because your finished video goes back through the model as the reference for every second it re-shoots. Per second at 720p that is 120 credits on the default engine (a new render there is 100), 100 on Seedance 2.0 Fast, 180 on Seedance 2.5, and 80 on MiniMax H3 at 768P (a new render there is 40).

Each video is one ad-ready variant. Creator covers about 1-3 fresh fifteen-second creatives a week and Studio about 3-8; for a faster cadence, we'll size a plan around your volume. Where you land in the range depends on the quality and engine you pick.

Don't copy. Riff. Adapt recreates the formula: pacing, hooks, emotional beats, never the footage. Every shot is generated fresh; flat graphics from the source (cards, stickers) can carry over. When Riffkit has the source's music as its own track, Adapt keeps that BGM by default: the music is part of why the video won, and the new video follows its beats. The track's rights stay with its owner, so check you're cleared to use it where you post. Swap re-renders the original's own shots, keeps its timing and the sound wherever no voice changes, and changes what you name, so use it on your own videos or a template; a template's music, voices and people are not rights-cleared.

Exactly like the monthly plan of the same tier: the same credits land at the start of every month of your year and refresh the next month. They do not stack up. Paying yearly buys a lower price each month, not a bigger pile of credits up front.

No. Yearly is paid up front and is non-refundable. Not sure yet? Start monthly and switch to yearly any time, from your next period.

Moving up a tier on the same billing interval takes effect immediately: you pay the prorated difference and the extra credits land in the month you are already in. Everything else (monthly to yearly, yearly to monthly, moving down a tier, or cancelling) takes effect at the end of the period you have already paid for, and nothing changes until then.
