HappyHorse Text-to-Video 1.1: Text to Video Online
Bottom line
Text-to-video with nine aspect ratios — from 21:9 ultrawide to 9:21 vertical — in clips of 4 to 15 seconds. Type a prompt into the Text to Video tool and HappyHorse Text-to-Video 1.1 renders it on VdoBloom credits — the cost is shown before you commit, and no HappyHorse API key is needed.
Nine aspect ratios is an unusual spread for a text-to-video model, and it's the headline reason to reach for HappyHorse Text-to-Video 1.1. Beyond the usual 16:9, 9:16, 1:1, 4:3, and 3:4, it adds 4:5 and 5:4 for feed-optimized posts plus 21:9 and 9:21 — true ultrawide and its vertical mirror — formats most generators simply don't offer. If you're after cinematic letterboxed shots or full-bleed vertical banners, this is one of the few models where you don't have to crop your way there.
The rest of the spec holds up. Clips run anywhere from 4 to 15 seconds in one-second increments at 720p or 1080p, which leaves room for slower camera moves and multi-beat actions that 5-second models can't fit. HappyHorse 1.1 is the current revision of the line and carries a 4.8 rating on VdoBloom.
Content filtering sits at the standard MODERATE tier, and generation is billed in VdoBloom credits with the amount shown before you commit a run.

Frequently asked questions
Which aspect ratios does HappyHorse Text-to-Video 1.1 support?
Nine: 16:9, 9:16, 1:1, 4:3, 3:4, 4:5, 5:4, 21:9, and 9:21. The 21:9 ultrawide and its 9:21 vertical mirror are the standouts — few text-to-video models offer either.

Does HappyHorse Text-to-Video 1.1 allow mature content?
It's rated MODERATE — standard filtering comparable to most mainstream providers. Typical commercial and creative prompts generate without friction, while explicit or otherwise prohibited content is blocked.
