What Kling AI Does Best
Kling AI is a video generation model from Kuaishou. You describe a scene, add images or reference video, and it returns a clip with native sound. Kling 4.0 doubles the single-generation length of Kling 3.0, from 15 seconds to 30 seconds. It accepts up to 10 keyframe images to steer the shot from start to finish. Its Omni Reference system pulls up to 15 reference assets into one generation, including up to 10 images, 5 videos, 7 subjects and 3 voice profiles. Prompts run up to 8,000 tokens. Output reaches 1080p today, with 4K and 10-bit HDR described as coming soon. Kling also offers agent access through its MCP server and a command-line tool, so automated workflows can call it directly. Kling is a raw model, not an editor. You plan the shots, pick the model and assemble the final video yourself. It shines for B-roll, product shots, social clips and visual ideas that would cost a fortune to film. It does not write your script or present your message.
What HeyGen Does Best
HeyGen is an avatar video platform. You write a script, pick an avatar, and it generates a presenter video with narration, captions and visuals. The free plan allows 3 videos a month, each up to 1 minute, with a watermark. The Creator plan adds 600 credits a month, videos up to 30 minutes, 1080p export and voice cloning. Pro starts at $49 a month with 1,000 credits and adds 4K export. Business costs $149 a month plus $20 per seat, with 1,500 shared credits and videos up to 60 minutes. HeyGen's Avatar IV model uses 1 credit per 3 seconds of video, or 20 credits per generated minute. Translation is a standout feature. Video translation without lip sync costs 2 credits per minute, with lip sync 5 credits per minute, and Precision mode 10 credits per minute. The platform lists more than 700 stock avatars and 500-plus stock Digital Twins, plus custom avatars you create from your own video. Its Video Agent can plan and assemble a video from a plain-language brief. HeyGen fits training videos, product explainers, multilingual content and faceless channels where a presenter carries the message.

| Entry paid | Standard $8.80 a month, 660 credits | Creator $29 a month, 600 credits |

Kling is far cheaper at the entry level. Its Standard plan costs $8.80 a month after a $6.99 first month, against HeyGen Creator at $29 a month. The credits are not comparable, though. Kling charges per second of video by resolution and audio, while HeyGen charges per generated minute and per translation mode. A 5-second Kling 3.0 clip costs 30 credits silent at 720p, or 60 credits at 1080p with audio. On Standard, 660 credits buy 22 silent 720p clips or 11 clips at 1080p with sound. HeyGen Creator's 600 credits buy about 30 minutes of Avatar IV video at 20 credits a minute. Kling's monthly credits expire after 31 days and do not roll over. Top-up credits last two years at a rate of $1 for 66 credits. HeyGen lets unused paid monthly credits roll over for one additional month, and annual-plan credits accumulate until renewal. Kling's yearly billing is about 34% off the list price. HeyGen's yearly billing takes about 17% off Creator and Pro, and 20% off Business.
Which One Should You Choose?
The choice follows the video you need to make. Choose Kling AI when the visual is the product: cinematic B-roll, product shots, social clips, storyboards brought to life, or any scene you cannot film. Its 30-second clips, keyframes and reference system give directors real control. Choose HeyGen when a presenter carries the message: training courses, onboarding, product explainers, sales videos and multilingual versions of the same script. Its avatars, voice cloning and translation pipeline are built for that job. Some creators need both. A common workflow is to generate B-roll in Kling and present it inside a HeyGen avatar video. That combination costs two subscriptions, so weigh it against hiring a presenter or filming the B-roll yourself. If you only need short clips with no presenter, Kling's $8.80 entry plan is the cheaper test. If you need talking videos longer than a minute, HeyGen's free plan gives you three one-minute tests before you pay.
Bottom Line
Kling AI wins for cinematic clips and visual storytelling, starting at $8.80 a month with 30-second generations and deep reference control. HeyGen wins for avatar-led presenter videos, translation and long-form training content, starting at $29 a month. They are complements, not substitutes. Buy Kling when the picture matters most. Buy HeyGen when the presenter matters most.
