Step 1
Mode
Reference, Image to video, or Video editing — first chip. Reference wants up to nine stills; the homepage list also names First frame and Text. Switching all three inside one clip would need a reason.
HappyHorse after a night in the studio: references, a first frame, and clip edits
I opened www.happyhorse.com and landed in a dark composer — no long landing scroll first. “Ride your imagination” hangs above the box; Featured and Discover wait below. HappyHorse notes is a notebook from that visit, not a mirror of their homepage.
I did not log in or hit Generate — Reference to video was already selected when the page loaded. HH 1.1 on the version chip, 16:9 / 720P / 5s in settings, Generate beside them. That is how the screen looked that evening. Defaults can change; the layout probably will too.
Discover feed
Five clips pulled from their CDN
I saved five files from Discover — not stock, not filler tiles. Open the card, grab the mp4 and poster, note what the file reports for length. The forest concert runs 15s; a couple of shore and puppy clips land closer to seven.
Default mode: references, not a blank prompt
Want the same screen? That is the studio, not this page — buttons here only open a short note.
After the visit
What HappyHorse is
The browser tab title is long and SEO-flavored: “HappyHorse AI Video Generator | Create AI Videos From Text & Images.” On the page itself the product name sits in plain sight — “HappyHorse, Ride your imagination” — with “Capture every fleeting spark. Let's gallop into reality.” underneath. That second line is marketing perfume; the composer underneath is the useful part.
I closed the Try for $1 badge without clicking it — the composer was enough to read for one evening. If I came back with real stills, I would start with Reference before Text; the @Image1 syntax is the part worth testing first.
Left rail: Studio, Home, Assets, Generate, a Try for $1 badge, Log in, CLI, Creation Guide. Center field: “Upload 1–9 images and describe how to use them in video,” with @Image1 walking into @Image2 as the worked example. Reference to video was the default that night. Under the box, two plain-English doors — generate (Reference / First frame / Text) and edit (Modify video details).
/creation repeats the pitch in fuller sentences: text prompts, photos, cinematic ads. Image to video and Reference to video sit together; editing is separate. Photos are inputs to a clip here, not a parallel stills factory — at least on the pages that were opened.
Live product: official HappyHorse website. Version write-ups sit in the model catalog; scenario pages follow how the studio splits URLs, not an attempt to pad a grid.
Controls on screen
Three steps, no secret pipeline
The order is whatever the composer and /cli already show — not a workflow invented for this page.
I skipped Generate entirely — mapping modes and chips was the goal, not burning credits on a first visit.
Step 2
Version and frame
Happy Horse 1.1 or 1.0 in the version menu; settings that evening read 16:9, 720P, 5s, and a lonely “1.” Discover cards already showed 1080P and 15s — so shorter defaults do not cap what the feed ships.
Step 3
Generate or CLI
Browser path: Generate. Agent path: /cli with Install CLI, copy command, log in inside the agent. Same studio, different door — not a third model name.
Two doors
Generation beside editing
Homepage and /creation split the product that way. No music tab, no chat tab — and none invented here.
Scenarios
When the studio is worth opening
Reference to video
Up to nine stills, @Image1 / @Image2 syntax in the box. Useful when the character or location already exists as photos — empty folder, empty mode.
Image to video
One starting frame instead of a pack. First frame on the homepage list points at the same family.
Text to video
/creation mentions text prompts outright. On the homepage the word Text sits in the trio with Reference and First frame.
CLI and agents
/cli describes a command pasted into an agent plus login there. Handy for pipelines; not tested end-to-end in these notes.
Lineup
Two names in the version menu
Nothing from other vendors — only what appeared under Select model version.
1.1 and 1.0 share one composer
The switch is a chip, not a separate site. Header buttons on this page stay local.
Worth the click
What the controls actually buy you
Three ways into a clip
Text, one frame, or a stack of stills — all named on the homepage and /creation. The upload row on Reference is on the first screen, so “does it take photos?” is not a mystery.
Version in plain sight
1.1 and 1.0 sit in the same chip menu, not buried in settings. Pick explicitly instead of guessing which engine ran.
Frame and length as chips
16:9 and 720P were the defaults that night; Discover and Standard / Pro copy mention 1080P and 15s. I would not assume every export matches the composer default without checking.
Editing and CLI as neighbors
Editing is its own mode; CLI is its own page with install steps. Two ways to stay inside the product — neither was invented for this write-up.
Fit
Who gets the most from this UI
People with character or product stills already
Reference mode asks for 1–9 images. No folder, no point — the field stays empty.
Short ad or cinematic shots
/creation names ads and cinematic clips; Featured is full of game and promo titles. Community shelf, not a case study authored here.
Fixing a clip that already exists
Modify video details is for nudging an export, not rebuilding from zero. Skip it if generation alone is enough.
Pipelines and agents
API & CLI plus in-agent login. Browser Generate remains; the CLI path was documented, not stress-tested here.
Pick the mode before Generate
Reference, Image to video, or editing — first chip, not a hidden pro drawer.
Questions
Answers from what was clicked
A consumer video studio at www.happyhorse.com. The headline reads “HappyHorse, Ride your imagination,” with Featured and Discover under the composer. Three creation modes sit in one chip row — references, a single still, or plain text — plus a separate editing mode. Version HH 1.1, 16:9, 720P, 5s were the defaults the evening these notes were written.
Only two names in Select model version: Happy Horse 1.1 (New) and Happy Horse 1.0. The compact chip says HH 1.1. Nothing else appeared in that dropdown, so the catalog here stops at Happy Horse 1.1 and Happy Horse 1.0.
Reference asks for up to nine stills and shows @Image1 walking into @Image2 in the placeholder. Image to video is the next chip; /creation groups both under Generate Video. Text is the third door on the homepage list. The part that took a second: First frame on the homepage and Image to video in the mode menu sound like cousins, not duplicates — see the reference notes for how the upload field differs.
The studio itself is on the official HappyHorse website. /creation, /subscription, /cli, and pricing pages sit there too. This site is notes only.
Editing is Modify video details in the homepage list — a neighbor of generation, not a hidden pro tab. On /subscription the copy mentions Free daily credits with two parallel jobs, Standard with queue priority, batch runs, watermark removal, and 1080P, Pro with unlimited parallel jobs. Credits can be bought without a plan. Dollar amounts change; the live page wins.
/cli is titled HappyHorse API & CLI with the line “Use HappyHorse in any agent with CLI command.” Steps: install from happyhorse.com/install-cli.md, paste into an agent, log in there. Browser Generate does not go away. I read the install doc; I have not run the command in production for these notes.
Reader notes
Five impressions of this write-up — not product reviews
Nine upload slots finally justified the reference folder on my disk. @Image1 in the placeholder reads like syntax, not decoration — took a second pass to believe that.

1.1 first, 1.0 still there. Prefer that to hunting a “legacy” toggle somewhere in docs.
Daniel Ortega · 5 out of 5
First frame vs Image to video still blurs for me, but 720P as default felt honest. 1080P only showed up on plans and finished cards — would want to confirm on a paid run.
Alina Kim · 4 out of 5
Editing as a sibling mode beats opening another site. “Modify video details” is vague, but at least it is not pretending to be a full NLE.
Paul Everett · 5 out of 5
CLI page answered the “browser only?” question. Install steps are clear; have not pasted the command into an agent yet.

Studio is next
I would go back for a paid run if I needed to confirm 1080P and watermark behavior — this page stops at what was visible without logging in. Composer layout, two version names, five Discover files — that is what the notebook covers. Credits and login stay on www.happyhorse.com.
