BEFORE YOUR FIRST TAKE
A few useful details.
What can I create with HappyHorse 1.1?
Create videos from a text prompt, animate one first-frame image, or guide a new scene with one to nine reference images. Text to Video uses one HappyHorse 1.1 model with a required prompt and optional reference images. First-frame animation uses Image to Video.
Which lengths and resolutions are supported?
Choose an integer duration from 3 to 15 seconds and 480p, 720p or 1080p output. Text and reference modes offer nine aspect ratios. Image to Video follows your first frame.
Does HappyHorse generate audio?
HappyHorse 1.1 generates native audio with the video. Its documented API has no separate audio toggle or uploaded audio-reference input.
Can I supply a final frame or edit an existing clip?
HappyHorse 1.1 Image to Video uses a first frame only. This 1.1 integration includes text, first-frame and reference-image generation. Browse Insvee's other video tools for end-frame direction, video editing or extension.
Which images can I upload?
Use JPG, PNG or WebP files up to 20 MB each. First-frame images need at least 300 pixels on each side and an aspect ratio between 1:2.5 and 2.5:1. Reference images need at least 400 pixels on each side.
How much does a generation cost?
Create shows the current credit estimate for your chosen model, duration and resolution before you generate. The shared plan comparison below shows current Insvee subscription options.
Is the coastal image a HappyHorse result?
The coastal image is original illustrative reference artwork created for this page. It is not a HappyHorse-generated video or a verified example of the model's output.
