Key features of Dreamina's AI game CG generator

Each game cutscene begins with an idea, but it takes planning, building, and refining to bring it to life. These are the features that describe how Dreamina supports each step of that journey.

Generate 30-second cutscenes from your script

Building a game cutscene from different short clips can make the final sequence feel uneven. Seedance 2.5 creates a full video from your script or scene description, with a maximum length of 30 seconds per video or 180 seconds in ultra-long beta mode. This results in all photos looking the same and less like the usual AI-generated look.

Input every creative asset with up to 50 inputs

Before production, gaming teams often have storyboards, character profiles, style references, shot descriptions, and sound effect references prepared. So, Seedance 2.5 allows the integration of those existing materials by taking up to 50 combined elements in a single input and converting them into a final game sequence.

Edit shots and audio without regenerating the scene

For a polished video, the images and sound need to be improved. Dreamina's localized precision editing lets creators select specific parts of a generated clip to remove, replace, or modify elements without regenerating the whole scene. Its audio tools can extract background music (BGM), voice timbre reference, and generate voice dialogue in multiple languages.

Benefits of using Dreamina's CG generator for games

Game makers often have to balance the needs of production with the goals of creativity. That's where Dreamina helps ease this challenge, making the CG generation process more efficient for creators to simplify visual creation, develop concepts, test directions, and create assets that enhance the overall experience.

Ensure polished results from scene to scene

If the AI character features or visual style change from shot to shot, the AI sequences can seem unstable. Dreamina guarantees consistency in faces, lighting, and textures across scenes, minimizing the post-production corrections required.

Iterate with greater creative control

The final result can be oversimplified by fitting the entire creative vision into a single prompt for a text-to-video generator. Dreamina uses existing design assets to keep key details, so you can refine ideas without losing the original design.

Combine multiple assets in one workflow

Creating game scenes often involves jumping between tools for visuals, voice and language versions. Dreamina's AI video generator does it all in a single workflow, so no delays, no need for separate audio tools.

How to create a game CG cutscene with Dreamina

Step 1: Write your scene or upload your character art

Open Dreamina's AI Video and describe the game scene you want to create, or upload your character art as a reference. Keep your description clear and focused. For example: A young knight walks through an ancient castle. The camera follows from behind. Warm lighting, cinematic style.

Step 2: Select Seedance 2.5 and generate

Select Seedance 2.5 from the model menu, choose your preferred aspect ratio, and set the clip length to up to 30 seconds. To generate a longer video, enable the ultra-long beta mode, which supports clips of up to 180 seconds. Then click Generate.

Step 3: Refine and download your video

Preview your video and review each scene. If anything looks out of place, use localized editing to remove or replace only the unwanted part while keeping the rest of the scene unchanged. If needed, apply HD Upscale to improve the final quality. Once you're satisfied, click Download.

FAQs about game CG generators

What's the best way to generate game cinematics?

The ideal method to create game cinematics is with a precise production plan rather than a single text prompt. Storyboards, character design, environmental themes, camera angles, and speech all contribute to the overall aesthetic of each scene. Dreamina's Seedance 2.5 supports single-clip generation of up to 30 seconds. Its ultra-long beta mode allows you to extend the clip length to 180 seconds for projects requiring longer storytelling, making it easier to create continuous cinematic scenes with fewer separate generations.

How can I create my own animated game character?

Typically, the first step in creating an animated game character is designing the character's appearance. This can include concept art, illustrations, or finalized character sheets that detail facial features, clothing, colors, and proportions. Once the design is finalized, animation tools can be used to give motion to the character so that it can be seen in different scenes. Dreamina, a CG character generator, allows you to create references to video, instead of building a character from scratch each time.

How long does it take to generate a game CG video?

The length of the clip, the amount of motion, the complexity of the scene, and the platform it will be used on all factors into how long it takes to create a CG video for a game. Short videos usually render faster, but scenes with lots of characters, detailed backgrounds, or complex camera movements can take longer. Dreamina, a game CG creator, offers fast video generation and free daily credits for creators who want to experiment without having to worry about every generation.

How do I create a cinematic trailer for my game?

Most creators begin with storyboards, character art, environmental designs, shot references, music, and dialogue before assembling everything into a trailer. Dreamina is able to take multimodal input with a maximum of 50 assets together, not just text. Storyboards, concept art, reference images, shot descriptions, and other production material can all work together to help creators maintain their original creative vision through the trailer with a video montage maker.

How do I keep a character consistent across multiple scenes?

For a character to be consistent in multiple scenes, the look, movement, lighting, and art style have to be consistent throughout the whole video. With no consistent references, AI-generated characters can look slightly different from shot to shot in their facial features, clothing, or expressions. Dreamina's Seedance 2.5 includes motion transfer and better visual continuity for increased shot-to-shot consistency. It preserves both motion and appearance over scenes and allows creators to generate more consistent game cinematics.
