Switch From Runway to Kling AI: Migration Steps and Gotchas

Moving between these two video services is straightforward if you plan it. Both turn text and images into short video clips. Both charge in credits. The differences are price, clip length, and workflow. Gen-4.5 costs 12 credits per second. The 3.0 model on the other service costs 6 to 12 credits per second depending on resolution and audio. This guide walks through the move in seven steps, compares the costs, and flags the gotchas that catch movers out.

Runway vs Kling AI: the key differences

The older service is the more polished editor. Its Gen-4.5 model is the current flagship. It takes text or image input and returns clips of 2-10 seconds at 720p. Base Gen-4 and Gen-4.5 cost 12 credits per second. Gen-4 Turbo costs fewer credits per second. The older service also wraps its models in a full editor with camera controls, motion brushes, and inpainting.

The newer service comes via Kuaishou. Its VIDEO 3.0 model supports text-to-video and image-to-video with optional native audio. The 4.0 model launched on October 15, 2026, with clips of 3-30 seconds and 4K output listed in its user guide. Credit rates are published on the 3.0 model. No per-second credit rate has been published on the 4.0 model. The cost shows on the Generate button before you confirm.

The table below compares the two on the numbers that matter in a move.

On price alone, the cheaper Standard plan sits on the newer service and includes slightly more credits. But credits are not equal across tools. A 5-second clip costs 60 credits on Gen-4.5. The same length on the 3.0 model at 1080p with audio costs 60 credits too. Compare your real clips, not the headline credit counts.

Step 1: Audit what you actually use on the old service

Before you move, list what you use. Open your projects on the old editor. Note which models you use most. Count how many clips you make each month. Note which features matter: camera controls, motion brush, inpainting, upscaling, or third-party models. The old service also offers access to other models, including the 4.0 model, via the same seat.

Write down your monthly credit spend. Standard gives 625 credits a month. That buys about 52 seconds of Gen-4.5 video, or roughly ten 5-second clips if every take works. If you use less than that, the cheaper Standard plan may cover you. If you use far more, compare the mid tiers instead.

Step 2: Export your prompts, images, and finished clips

There is no one-click migration between these tools. You move your assets by hand. Download your finished clips first. Save your starting images and reference frames. Copy your best prompts into a document. Prompts do not transfer automatically. Keep the ones that worked.

Also save any brand assets. Logos, product shots, and style references must be re-uploaded on the new service. Check your storage limit on the old editor. The free plan includes 5 GB. Standard includes 20 GB. Pro includes 100 GB. Max includes 500 GB. Download everything you want to keep before you cancel. Cancelled accounts can lose access to stored work.

Step 3: Set up the new service and test with free credits

Go to the official site, kling.ai. The older klingai.com address redirects there. Sign up with Google, Apple, or email. The Basic plan costs $0. It has no monthly credit allowance. You get credits via sign-up and via logging in each month. Free exports carry a watermark. They are for personal use only.

Test before you pay. Generate a few clips with your saved prompts and images. Try text-to-video and image-to-video. Try native audio if your work needs sound. Watch the credit cost shown on the Generate button. The 4.0 model has no published rate, so the button is your only price signal. Run the same prompt two or three times. Compare the keepers, not the first try.

Step 4: Rebuild your best prompts on the new service

Prompts do not behave the same on both tools. A prompt that works on the old editor may fail on the new one. Start with your top five prompts. Run each one with the same starting image. Note what changes. The 3.0 model handles motion and camera moves well, but wording matters. Short, concrete prompts usually beat long ones.

Keep a simple log. Record the prompt, the model, the resolution, the clip length, and the credit cost. After ten tests you will know which prompts transfer cleanly and which need rewrites. Do this before you move live projects. It saves credits and missed deadlines.

Step 5: Compare real costs on your own clips

Do the maths on your own work, not on marketing pages. A 5-second 3.0 clip at 720p without audio costs 30 credits. At 1080p with native audio, the same clip costs 60 credits. On the old editor, a 5-second Gen-4.5 clip costs 60 credits.

Now price your month. If you make twenty 5-second clips a month at 1080p with audio, the new service needs 1,200 credits. That fits inside Pro at 3,000 credits a month. On the old editor, the same twenty clips on Gen-4.5 need 1,200 credits too, which fits inside Pro at 2,250 credits. The cheaper plan wins only if your clip mix matches its strengths. Longer clips favour the 4.0 model, which runs up to 30 seconds. Short iteration favours Turbo, which costs fewer credits per second than Gen-4.5.

Step 6: Check licences and commercial use before you publish

This is the gotcha that bites hardest. Free output on both tools is watermarked and limited. Basic output on the new service is for personal, non-commercial use. Free output on the old editor is watermarked too. Do not publish free-tier clips in ads or client work.

Paid plans on the new service remove the watermark and allow commercial use. Paid plans on the old editor remove the watermark as well. Check the terms on the exact plan you buy. If you work with clients, confirm the licence covers client delivery, not just your own channels. Keep a record of which plan generated each published clip.

Step 7: Move projects gradually, then cancel the old service

Do not cancel on day one. Run both tools over a month. Move one project at a time. Start with low-risk work, such as social clips. Keep client work on the old editor until the new service has proven itself on your prompts. Watch two things: the keeper rate and the real credit cost per finished clip.

Remember the credit rules. Standard and Pro credits on the old editor reset each cycle and do not roll over. Max credits roll over for one month. Purchased top-up credits never expire. Membership credits on the new service expire after 31 days. Separately purchased credit packs stay valid for two years. Failed generations on the new service are refunded under its credits policy. That softens the cost of bad takes.

When the trial month proves the new service works on your prompts, cancel the old one. Keep your exports and prompt log. You can always return. Plans on the old editor start again at the free tier with 125 one-time credits.

Gotchas to watch when you switch from Runway to Kling AI

• No published 4.0 rate: No per-second credit cost has been published on the 4.0 model. Check the Generate button every time.
• Credits expire: Membership credits on the new service expire after 31 days. Standard and Pro credits on the old editor reset each cycle. Do not stockpile.
• Watermarks on free tiers: both free plans watermark output and limit commercial use. Pay before you publish work.
• Separate accounts: The international and China-mainland sites are separate account systems. Stick with the international site.
• Prompt behaviour differs: the same prompt gives different results on each tool. Budget a test week.
• Gen-4.5 is paid-only: the free plan's 125 credits cannot run the flagship model. Test it only on a paid plan.

Bottom line

The move makes sense when your clips are longer, your volume is steady, or the cheaper Standard plan covers your month. Standard on the new service costs $8.80 a month after a $6.99 first month, with 660 credits. Standard on the old editor costs $15 a month, with 625 credits. But the saving only holds if your clip mix fits the new service's strengths. Test with free credits, rebuild your best prompts, price your real clips, and move one project at a time. Keep the old editor live until the new service has earned the move. Prices were checked on both vendors' own pricing pages on 11 November 2026. Confirm the checkout price before you pay.
