MiniMax H3 vs Kling 3.0

On paper they look alike on DreamBench: both make 720p and 1080p in the same five aspect ratios, from 21:9 to 9:16, and both render up to 15 seconds a generation. The rows above come from the MiniMax H3 and Kling 3.0 pages’ own tables. The differences are in sound, speech and where each runs, as the makers’ pages, read on November 1, 2026, and DreamBench’s settings show.

A DreamBench video uses one model for every scene. To compare them on your own brief, make the video twice in Film Studio, once on each, and keep the one you prefer.

The two makers list different languages. MiniMax’s model card names 11 with stable support: Arabic, Chinese, English, French, German, Italian, Japanese, Korean, Portuguese, Russian and Spanish, and says others work to varying degrees. Kling’s Video 3.0 guide names 5, Chinese, English, Japanese, Korean and Spanish, and says a line in any other language is translated into English. Portuguese, French, German, Italian, Russian and Arabic lines therefore point to MiniMax H3.

Kling goes further on delivery. Its guide lists English accents, American, British and Indian, and Chinese dialects such as Cantonese and Sichuanese, lets characters switch language within one scene, and writes each line with its speaker and how they say it. Its Kling 3.0 page says the model matches each voice and lip movement when several characters speak. MiniMax’s pages describe no accents and make no claim about several speakers.

On DreamBench, the voice comes from the words in the prompt on both models: there is no voice recording to upload. Put each spoken line in quotation marks, give it to a named character and name its language. Keep it short enough to say in the clip, at about 2 words a second.

Every MiniMax H3 clip is generated with stereo sound, on DreamBench and in MiniMax’s own description of the model, so describe what should be heard as well as what should be seen. Kling 3.0 generates sound with the picture when sound is on, dialogue, effects and ambience that follow the action, and makes picture only when it is off.

The switch matters when the sound will come from somewhere else: a voice-over, a brand track or music added in an editor. On DreamBench, a silent Kling 3.0 clip uses fewer credits per second than one with sound. A MiniMax H3 clip always carries its own soundtrack, which you would mute or replace afterward.

MiniMax H3, and not Kling 3.0

• Runs on DreamBench’s Video page: one clip of 5 to 15 seconds, your prompt sent as written.
• Speaks the 11 languages its card lists reliably, French, German, Italian, Portuguese, Russian and Arabic among them.
• Comes out in stereo on every clip.
• Has published weights, under MiniMax’s own H3 Community License, for people who run it themselves.

Kling 3.0, and not MiniMax H3

• Lets you switch sound off, for fewer credits.
• Speaks with the accent or dialect you name, and switches language within one scene.
• Matches lines to several speakers’ voices and lips, by Kling’s account.

Their makers’ tools do more than DreamBench uses. Both take a first and last frame there, and both can cut between shots inside one clip; MiniMax H3 also takes reference video and audio and edits footage, and Kling 3.0 locks a character’s look with Elements. On DreamBench, each clip of either model starts from an opening frame DreamBench makes from your references and is one shot: a new shot is a new scene.

Limits in the makers’ words: MiniMax says H3’s visual detail can still be improved in certain scenarios. On DreamBench, a Kling 3.0 clip doesn’t cut to a new setting partway through, and a new film is cut into clips of 3 to 12 seconds on both models.

On the Video page, MiniMax H3 gets your prompt exactly as you wrote it. MiniMax reports that H3 follows instructions closely, so a precise brief pays: describe the shot size, the action, the camera move, then what is heard, with each spoken line in quotation marks and its language named. Where lettering or a logo matters, choose 1080p and keep one subject in frame.

Kling 3.0 runs in Film Studio, where DreamBench writes each scene’s prompt from your brief, so your brief is what to get right. Kling’s guide writes a continuous take: the frame, the action beat by beat with timed moments such as “at the 4th second”, the camera, the look, then the sound, and dialogue as Name (how they say it): “the line”. DreamBench’s Kling 3.0 prompts leave music out.

• Name the language of every line, on both models.
• Give MiniMax H3 the sounds you want: every clip has them, so say what they are.
• Give Kling 3.0 one main action a scene, a few seconds long; its clips on DreamBench are one shot each.
• In Film Studio, tag a reference image and name it with @ in your brief, on either model, so DreamBench builds it into each opening frame.
