💥 Step-by-Step Guide to Using HappyHorse “Text-to-Video”
The first step when working with the “Text to Video” feature is to correctly structure your text prompt.
Writing a text prompt
Generation quality in HappyHorse directly depends on the structure and order of your prompt. The model works best with short, clear scenes that include one main action, a specific environment, and detailed object physics.
Overloaded, overly complex, or abstract prompts may cause errors, artifacts, and inconsistencies in scene logic.
A good text prompt should include:
- Main subject / character
- Action
- Location
- Camera movement
- Lighting / atmosphere / style
Example prompt:
“A man in a strict black suit stands by a panoramic skyscraper window and slowly adjusts his wristwatch, an evening rainy city in the background, smooth camera push-in, soft cold street lighting, realistic reflections on the glass, natural fabric and hand movement.”
Model settings
After submitting your text prompt, click the “Text to Video” button and correctly configure the settings for the future generation.
Prompt
If necessary, you can adjust your prompt in this field. If left unchanged, the generation will use the original text prompt you submitted initially.
Resolution
When working with text prompts, you can choose between two resolution options:
• 720p
A medium video resolution that offers a good balance between quality and file size. It is a popular standard for online videos, including YouTube, and provides a clear image suitable for medium-sized TVs and most modern devices.
• 1080p
A high-resolution video format with greater detail and sharpness. It is ideal for large screens and TVs, but requires a faster internet connection and significantly more storage space. In return, it delivers the clearest and most detailed video quality.
Aspect ratio
When working with text prompts, you can choose from 5 aspect ratio options:
Duration
You can set the duration of the future video from 3 to 15 seconds.
❣️ Please note that the default duration in the settings is 5 seconds.
Seed
Seed lets you generate identical or highly similar results when repeating a generation. It is especially useful if you liked a video and want to create a similar result while changing or adding specific details.
You can copy the Seed value from the generated video description and use it to reproduce the result with the necessary changes. To do this, paste the copied Seed into this field.
If you do not need to create a similar video, we recommend enabling Random Seed. This way, each generation will use a new Seed value and produce results that differ from previous generations.

💥 Step-by-Step Guide to Using HappyHorse “Image to Video”
The first step when working with an image is to upload it correctly.
Image upload
Technical requirements for images:
• You can upload images in JPG and PNG formats.
• Maximum file size: up to 10 MB.
• Maximum number of uploaded images: 1.
For example:
Model settings
After uploading an image, select the “Image to Video” button and correctly configure the settings for the future generation.
❣️If you want to remove the uploaded image, click the “Delete image” button. After that, you will be able to upload a new image.
Prompt
Generation quality in HappyHorse directly depends on the structure and order of your prompt. The model works best with short, clear scenes that include one main action, a specific environment, and detailed object physics.
Overloaded or overly abstract prompts may cause errors, artifacts, and inconsistencies in scene logic.
A good text prompt should include:
- Main subject / character
- Action
- Location
- Camera movement
- Lighting / atmosphere / style
❣️Entering a text prompt is optional: if you leave the field empty and upload only an image, the neural network will independently determine the action in the scene.
Example prompt:
“A girl stands by an open window during the rain and slowly looks outside, the wind gently blows her long hair and light white curtains, raindrops run down the glass, soft natural window light, smooth camera movement, realistic cloth, hair, and rain physics, atmospheric scene.”
Resolution
When working with a single image, you can choose between two resolution options:
• 720p
A medium video resolution that provides a good balance between video quality and file size. This format has become a popular standard for online videos, including YouTube, and delivers a clear image suitable for viewing on medium-sized TVs and most modern devices.
• 1080p
A high-quality video format that provides excellent detail and sharpness. This format is ideal for viewing on large screens and TVs, although it requires a faster internet connection and significantly more storage space. In return, it delivers the clearest and most detailed video quality.
Duration
You can set the duration of the future video from 3 to 15 seconds.
❣️Please note that the default duration in the settings is set to 5 seconds.
Seed
Seed allows you to generate identical or highly similar results in style when repeating a generation. If you liked a video and want to create a similar result while changing or adding specific details, the Seed setting will be especially useful.
In the description of a generated video, you can copy the Seed value and use it to reproduce the result with the necessary changes. To do this, paste the copied Seed into this section.
If you do not need to create a similar video, we recommend enabling Random Seed. This way, each generation will use a new Seed value and produce results that differ from previous generations.
