Fast vs Standard and 480p vs 720p: Spend Your Credits Wisely

Every WaifuRush generation spends credits, and two settings change the price of a clip more than anything else: quality and resolution. Choosing well is the difference between finding a great result in a few cheap tries and burning through your balance on rerolls at the highest settings.

This guide explains what each option does, how they affect cost in relative terms, and a workflow that keeps spending under control. We do not list exact credit amounts here, because they are shown in the studio before you press Create and may change. What stays true is how the options compare.

The two settings

Quality: Fast (turbo) or Standard

Fast, also called turbo, is the quicker, cheaper option. Standard uses more compute per second of video and costs noticeably more. In practice, Standard is meant for the final render of a clip you already know is good, while Fast is for exploring.

Resolution: 480p or 720p

720p is the default and gives a sharper picture. 480p is lighter to generate and costs about 20% less than 720p for the same quality. The saving is modest, so resolution is a smaller lever than quality.

These two choices are independent, so there are four combinations. From cheapest to most expensive for a given duration: 480p Fast, then 720p Fast, then 480p Standard, then 720p Standard.

What else changes the price

• Duration: cost scales with the length of the clip. In Nsfw video pro and Nsfw director you choose 5, 8, 10 or 15 seconds. The loop mode and the live wallpaper generator make 5 second clips.
• Continuations: a clip made with the director mode costs more than a fresh clip of the same length, because the earlier video is processed as context as well.
• Failures: if a job fails, or you cancel it while it is still being prepared, the credits are refunded automatically.

The exact number of credits for your configuration is always displayed in the studio next to the Create button, so you can check it before committing.

What you can expect from each tier

We do not publish benchmark numbers, so treat the following as practical guidance rather than measurements. Your own images are the real test.

• Composition and motion: usually decided at any tier. If the motion idea is wrong at 480p Fast, it will be wrong at 720p Standard too. This is why drafting at the low tier works.
• Fine detail: eyes, hair strands, jewelry and patterns benefit most from higher resolution and Standard quality.
• Stability: Standard can hold details more steadily in difficult shots. If a clip flickers at Fast, try Standard before giving up on the image.
• Viewing size: on a phone screen, 480p can look perfectly acceptable. On a large monitor or a shared full-screen display, 720p is noticeably better.

The draft-then-final workflow

1. Draft with Fast quality. Fast is what makes a draft cheap; 480p saves only about 20% more. Use drafts to test source images, ideas and durations.
2. Compare a few attempts. Change one thing per attempt: the image, the idea, or the seed.
3. Lock the seed of the attempt you like in Settings, so the final render keeps the same motion.
4. Upgrade only the winner: render once at 720p. If that already looks great on Fast, stop there.
5. Use Standard only if you still see problems or if the clip is going somewhere it will be viewed large.

A decision guide

• Testing a new image or idea: Fast, at 480p or 720p.
• Final clip for a phone, a story or a profile animation: 720p, Fast.
• Final clip for a large screen, a portfolio piece or a hard shot with tricky details: 720p, Standard.
• Long clips (10 or 15 seconds) and continuations: draft with Fast, because these are the most expensive and any mistake costs the most.
• A multi-part scene: keep the same resolution and quality for all parts of the final, so the cuts match.

Common ways to waste credits

• Generating long clips before you know the image works. Test with 5 seconds first.
• Rerolling at the highest tier hoping for luck. If an image fails twice at the draft tier, change the image, not the tier.
• Making vague changes between attempts. If you change image, idea and duration at once, you cannot learn what helped.
• Choosing Standard for drafts. Quality changes the price far more than resolution does.
• Forgetting to lock the seed. A great motion you cannot reproduce is an expensive lesson.

Credits, plans and packs

Credits come from paid plans or credit packs. Plans include a monthly allowance, and higher plans add things like more simultaneous generations, private creations and commercial use. Which one suits you depends on how much you create. If you draft cheaply and finalize rarely, a smaller allowance goes a long way.

Quality and the input image

Settings cannot rescue a poor source. A blurry, over-compressed or cluttered image will stay that way at 720p Standard, only more expensively. Before touching the quality settings, check the picture. Our guide to preparing input images lists what to look for.

Summary

Draft on Fast, finish high, and change one thing at a time. Fast is the tool for finding the shot (480p trims the price a little further); 720p and Standard are tools for polishing a shot you already trust. Used in that order, they make your credits go much further.
