Frequently asked questions
What is HappyHorse 1.0 Extend?
HappyHorse 1.0 Extend is a video continuation model that picks up an uploaded clip from its ending and generates 3-15 seconds of new matching footage at 720p or 1080p. On Zorq AI it runs in the browser — sign in with Google or Apple, upload, prompt and generate.
How many credits does HappyHorse 1.0 Extend cost?
5 credits per second at 720p and 10 credits per second at 1080p. Adding 5 seconds at 720p is 25 credits. Zorq plans start at $9/mo billed annually with 200 credits.
Should I use 1.0 Extend or 1.1 Extend?
At 720p they cost the same; at 1080p, v1.1 is cheaper (7 vs 10 credits per second). v1.1 is generally the better default — 1.0 remains available if you prefer its output on a particular clip.
Does the extension include audio?
No — HappyHorse renders silent footage. Re-add music or voiceover in Zorq's audio tools after assembling the final cut, or use Seedance 2.0 Extend for audio-native continuation.
Can I extend clips from other models?
Yes — any video you upload can be extended, whether it was generated on Zorq with another model or filmed on a phone.
