Preface
Making video with AI usually starts with the same problem: too many ways in, and no clear sign of which one fits what you're actually trying to make. LTX runs a free creative studio, a pay-per-second developer API, and a fully open-source model that can be trained and run on your own machine — three doors into one underlying engine. This book walks through all three: what each one actually costs once a real project runs through it, how a shot goes from a plain sentence to finished footage, how a character is made to look the same twice, and where the free tier quietly stops being enough. By the end you will know which door to walk through first.
Chapter 1
Three Doors Into the Same Model
A marketer with a fifteen-second product ad due Friday opens ltx.io for the first time expecting one button and one price. What actually loads is a homepage advertising a research model, a creative studio, a developer API, and an open-source repository, all under one name, all pointing at each other.
That confusion is fair, because it is genuinely one thing wearing three faces. Underneath all of it sits the same LTX video and image model. What changes is how you reach it: through a no-code workspace built for people who never want to see a line of code, through a metered API built for people wiring generation into their own product, or through the raw open-source weights for anyone willing to run the thing themselves.
The choice matters more than it looks. A team producing one campaign a month wants the workspace. A product bolting video generation into its own app wants the API, billed by the second rather than by the seat. A studio that cannot let footage leave its own servers, or wants to fine-tune the model on its own footage, wants the open weights.
None of the three is the 'real' LTX and the others a cut-down version. They are the same model, wearing different clothes for different jobs, and picking the wrong one is the single most common way a first project with LTX goes over budget or over deadline before a single clip is finished.
What you can actually do here
LTX's model does more than generate a clip from a sentence. Grouped by what a project actually needs at each stage, here is the fuller range captured from the site.
Starting from nothing
| Use | Who it fits | Where | Worth knowing |
|---|---|---|---|
| Text to video | Anyone starting from a written idea | LTX Studio gen space, or the API's text-to-video endpoint | Full camera and motion control Fidelity depends on model and resolution tier chosen |
| Image to video | Anyone with a product photo, poster or still frame | LTX Studio gen space, or the image-to-video API endpoint | Preserves the source frame's identity |
| Audio to video | Music videos, lip-sync, sound-driven scenes | API audio-to-video endpoint, WAV/MP3/M4A/OGG input | Voice and music shape pacing and motion directly 1080p only, generates up to ~20 seconds per request |
| Combined text, image and audio input | Anyone needing tighter creative control than one input allows | LTX Studio gen space, mixed-input mode | One generation pulls from all three sources at once |
Fixing and refining
| Use | Who it fits | Where | Worth knowing |
|---|---|---|---|
| Retake a specific segment | A shot that's 90% right | LTX Studio editing tools, or the API Retake endpoint (ltx-2-3-pro only) | No need to re-render the whole clip Billed on the uploaded input video's length, at 1080p only |
| Extend a clip past its end | A shot that's too short and needs to keep going | LTX Studio editing tools | Continues from the last frame with no visible seam |
| Upscale resolution or frame rate | Delivery specs that need 4K or 60fps | LTX Studio upscale tool, paid plans | Recovers detail without a full re-generation Free plan excludes upscaling entirely |
| Convert SDR footage to HDR | Colorists finishing for broadcast or streaming delivery | SDR-to-HDR tool, exports 16-bit EXR | Restores clipped highlights and flat shadow detail |
| Colorize black-and-white footage | Archive restoration and period-footage work | AI Video Colorization tool | Guided by a prompt, not automatic-only |
| Remove or replace an object | Cleaning a shot without reshooting it | AI Video Outpainting / object-removal tool | Preserves the rest of the scene untouched |
Staying consistent
| Use | Who it fits | Where | Worth knowing |
|---|---|---|---|
| Save a reusable character, object or location | Any project running more than one shot | LTX Studio Elements panel | The same face, prop or set persists across a project Saving Elements requires a Standard plan or above |
| Transfer camera movement or performance from a reference clip | VFX and animation teams matching a specific move | IC-LoRA workflow in ComfyUI or LTX Desktop | Copies motion structure, not just appearance |
| Train a custom LoRA | Studios building a house style or a recurring character | LTX Trainer, on LTX-2.3 open weights | Full ownership of the trained result Requires a prepared dataset and real GPU time |
Going to production
| Use | Who it fits | Where | Worth knowing |
|---|---|---|---|
| Storyboard and pitch deck generation | Pitching a project before a single frame is shot | LTX Studio storyboard and pitch-deck tools | Turns a script into visual sequence automatically Pitch decks require a Standard plan or above |
| Run the model on your own infrastructure | Enterprises needing zero data leaving their servers | LTX-2 open weights via HuggingFace or GitHub | Fully open source, self-hostable and fine-tunable Requires consumer or enterprise-grade GPU hardware |
Chapter 2
One Model Called LTX, Wearing Three Different Names
Ask what version of LTX you're actually using and the honest answer is a small family of numbers: LTX-2, LTX-2.3, and LTX-2.5, each a generation of the same underlying architecture rather than three separate products.
LTX-2 is the original open-weight release — full model weights and training framework published publicly, meant to be downloaded, run locally, and built on without restriction. LTX-2.3 followed as a production-focused upgrade, shipped alongside LTX Desktop, a dedicated video editor built directly on the engine rather than around it. LTX-2.5 is the newest generation, described on the site as bringing pixel diffusion, native multishot generation and full HDR ACES support for filmmaking pipelines specifically.
The Studio and the API both give you a choice between Fast and Pro variants of whichever generation is current. Fast is built for iteration and previews and is the only variant that reaches the higher resolution tiers; Pro is built for final, client-facing output and tops out lower in resolution in exchange for steadier motion and fewer visible artifacts.
The practical upshot: a rough cut and a delivered ad are not the same job, and LTX expects you to pick a different variant for each rather than running everything through one setting and hoping it holds up at both ends.
Chapter 3
What Eight Hundred Free Credits Actually Buy
Someone testing the water before committing budget signs up for the free LTX Studio plan expecting a trial period. What they get instead is a one-time allowance: 800 credits, given once, with no monthly refill and no billing attached.
Those credits still unlock a genuinely usable slice of the platform — both the LTX-2.5 and LTX-2.3 video models, the Z-image model, advanced camera controls, blank storyboards, audio-to-video generation, SDR-to-HDR conversion, node-based Flows automation, and video-to-video control. What the free plan does not include is upscaling, editing tools, or a personal use license that covers anything beyond posting to your own social profiles and personal website — no promotional or commercial use of any kind.
Because credits are consumed by action rather than by time, the free allowance behaves less like a trial period and more like a small prepaid balance. A handful of test generations, a few camera-angle experiments, one attempt at a consistent character — and then it's gone, permanently, with no reset date to wait for.
That design answers the question a lot of people ask before signing up at all: is this free plan enough to actually finish something? For a personal experiment, yes. For anything meant to go out under a brand name, the license alone rules it out before the credits do.
Chapter 4
The Month the Free Plan Stops Being Enough
The moment usually arrives the same way: the free 800 credits run out mid-project, or the work in progress turns out to be for a client rather than a personal page, and the personal-use license quietly disqualifies it.
From there, LTX Studio's paid tiers each add a genuinely different layer rather than just more of the same. Lite, at $12 a month billed yearly, adds a monthly refill of 8,000 credits, upscaling, basic editing tools and removes the watermark — the first tier where output is meant to leave the platform looking finished. Standard, at $28 a month billed yearly, is where the platform opens up: Nano Banana 2 and Pro, FLUX.2 Pro, Kling 2.6 Pro and Kling 3.0 Pro, and ChatGPT Images 2.0 all become available as generation models, alongside saved and reusable Elements, advanced Flows automation, AI Storyboards, pitch decks and a commercial use license.
Pro, at $100 a month billed yearly, adds Google's Veo 3.1 family of models, three collaborators per project, and on-demand credit top-ups for when even 110,000 credits a month run short. Above that sits a custom Enterprise tier built around organization-wide controls, security compliance and dedicated account management rather than more generation capacity per se.
The pattern worth noticing: the jump from Lite to Standard is not really about more credits, it's about which models and licenses become available at all. A project that needs Kling or FLUX specifically has to be on Standard or higher regardless of how few credits it actually uses.

Chapter 5
Paying by the Second Instead of by the Month
A developer building video generation into their own app has a different problem than a monthly subscriber: unpredictable volume that a flat monthly plan doesn't fit cleanly. That's what the LTX API is built for, and it is billed per second of output rather than per request or per asset.
Text-to-video and image-to-video on the Pro variant run $0.12 per second at 1280×720 and $0.17 per second at 1920×1080, with Pro topping out at 1080p — anything at 1440p or 4K has to go through the Fast variant instead, which prices at $0.09 (720p), $0.13 (1080p), $0.19 (1440p) and $0.30 (4K) per second. Audio-to-video runs $0.17 per second, billed on the length of the input audio rather than the output, generating up to roughly 20 seconds per request; longer pieces are built by chaining multiple requests together. Retake, which requires the Pro variant specifically, is billed at $0.10 per second of the uploaded input video, at 1080p only.
A concrete example makes the shape of this clearer: a 20-second 1080p ad clip generated on Pro costs about $3.40 in generation alone, before any Retake passes to fix a shot that came out wrong. Run the same clip through three Retake passes on a 20-second segment and that adds another $6 or so — which is the moment a lot of developers realize Retake is priced for surgical fixes, not for iterating toward a final cut.
With automatic duration, billing follows however long the model actually renders rather than a duration you specify up front; on prepaid accounts, credits are held against the maximum length your resolution and frame rate allow, and whatever goes unused is released once the job finishes. That detail matters for anyone budgeting a batch of generations against a fixed credit balance rather than a card on file.
Chapter 6
Describing a Shot So the Model Actually Understands It
The gap between a forgettable AI clip and a usable one is rarely the model — it's almost always the prompt. LTX's own guidance is specific: describe the subject, the setting, the camera angle, the lighting and the mood, not just the general idea of the scene.
"A dramatic sunset over the ocean with a slow pan camera movement" is the site's own example of what a working prompt looks like, and the reason it works is that every clause in it does a different job: subject, setting, camera behavior and tone, each named rather than implied. A prompt that just says "a beautiful sunset" leaves the model to guess at all four, and it will guess differently every time.
Camera control in LTX Studio goes further than the prompt itself — keyframes and visual references let you direct a shot the way you'd direct an actual camera operator, rather than describing motion in words and hoping the model interprets it the way you meant. Preset visual styles, from cinematic to sketch to branded looks, exist specifically to keep that direction consistent across a whole project instead of having to redescribe the same look in every prompt.
The habit worth building early: write the prompt the way you'd brief a cinematographer, not the way you'd describe the shot to a friend. The extra ten seconds spent naming the camera move is usually the difference between a usable first take and a second one.
Chapter 7
Making the Same Face Show Up Twice
Generate the same character prompt twice on most AI video tools and you get two different faces — which ends any story or ad campaign that needs one recognizable person across multiple shots. LTX Studio's answer is Elements: a stored asset — a character, an object, or a location — saved once and called back into any later generation.
Once an Element is saved, it persists across a project rather than needing to be re-described in every new prompt. That is what makes a multi-shot ad, a short film with a recurring character, or a branded mascot appearing across a whole campaign practical rather than a matter of luck. Saving Elements is a Standard-plan feature; the free and Lite tiers can generate with the model but can't build a reusable library of characters to draw from.
For anyone working outside LTX Studio's interface — in ComfyUI or LTX Desktop directly — the equivalent tool is IC-LoRA, which transfers camera movement, scene structure or a specific human performance from a reference video into a new generation. It's a more technical route to the same goal: consistency that survives from one shot to the next, whether that consistency is a face, a set, or the way a character moves.
The distinction worth remembering: a prompt describes what something looks like once. An Element or an IC-LoRA reference is what makes it look the same way the second, tenth, and fortieth time.

Chapter 8
A Still Photograph Learns to Move
A real-estate listing has one still photo of a property and a deadline for a video walkthrough. Reshooting isn't an option; the photo is what exists. Image-to-video is built for exactly this situation — animating a still into smooth, coherent motion rather than generating a scene from nothing.
Because the source image already defines the subject, framing and lighting, the model has far less to guess at than with pure text-to-video, which is part of why image-to-video pricing runs on the same Pro/Fast rates as text-to-video rather than a premium tier of its own. The starting image effectively is the first frame of the video.
Audio-to-video works the same logic in reverse: rather than a static image anchoring the scene, a piece of audio — voice, music or sound — drives the motion, pacing and structure of the generated clip directly. It accepts WAV, MP3, M4A and OGG files, with an optional image alongside it, and currently only outputs in 1080p, generating up to roughly 20 seconds per request. A full-length piece is assembled by chaining several of these requests together rather than generating the whole thing in one pass.
Both routes solve the same underlying problem from opposite directions: one starts from what something looks like, the other starts from what it sounds like, and either one gives the model a stronger anchor than a blank prompt does.
Chapter 9
Fixing the Five Seconds That Went Wrong
A ten-second generated shot is nine seconds right and one second wrong — a hand that morphs oddly, a background object that flickers. Re-rendering the whole clip to fix one second wastes both the credits already spent and whatever was good about the first nine.
Retake exists for exactly that moment: it regenerates a specific segment without touching the rest of the clip. On the API it requires the ltx-2-3-pro model specifically and is billed at $0.10 per second of the input video you upload, at 1080p — a narrower, cheaper operation than a full re-generation because it's only reworking the part that failed.
Extend solves the opposite problem — a clip that's simply too short — by continuing from the video's last frame with a new prompt, without a visible seam where the two segments meet. Between Retake and Extend, most of the everyday frustrations with generated footage — wrong details, or not enough footage — have a direct fix rather than requiring a full restart.
For finishing work rather than fixing mistakes, upscaling (resolution and frame rate) and the SDR-to-HDR conversion tool both operate on already-generated footage: the former is for delivery specs, the latter for handing a clip to a colorist with real dynamic range to grade against, restoring highlight and shadow detail that a standard-range export would clip. Both sit behind a paid plan — the free tier can generate, but can't refine.
Chapter 10
Where the Free License Ends
Every plan on LTX Studio comes with a real limit, and knowing it before starting a project avoids the moment where finished work turns out to be unusable for its actual purpose.
The clearest one is licensing: the free plan's 'personal use' license covers content posted to your own social profiles and personal website, and nothing that promotes a business, service or product. A commercial license — required for anything client-facing, sponsored, or produced for a brand — only starts at the Standard tier and above.
Individual shot length is model-dependent rather than fixed: shots typically run from about 3 to 20 seconds, with longer sequences built by joining multiple clips together in the Timeline rather than generated in a single pass. Audio-to-video carries the same roughly-20-second ceiling per request. Refunds are handled through a 14-day window from payment, and only where usage hasn't exceeded 1,200 credits — a request made on day 13 after generating 3,000 credits' worth of footage won't qualify.
And one line in LTX's own pricing terms is worth remembering longer than any single feature: the company reserves the right to update, modify or replace available models over time, without guaranteeing any specific model stays available indefinitely. A workflow built around one named model today is worth checking against the current model list before it's relied on for a recurring production pipeline.
Questions readers actually ask
Is LTX Studio actually free to use, or is that just a trial?
The free plan is real and permanent, not a time-limited trial — it gives 800 credits one time, with no monthly refill, for personal, non-commercial use only.
Can I use LTX Studio on my phone?
No. LTX Studio is designed for desktop use through a web browser; there's no mobile app, and mobile browser access isn't the intended way to use it.
What's actually the difference between LTX-2 and LTX Studio?
LTX-2 is the underlying AI model that generates the video and image content. LTX Studio is the full production platform — storyboarding, editing, Elements, delivery — built around that model, alongside several other AI models it also integrates.
Is the LTX model itself open source?
LTX-2 is fully open source, with complete model weights and its training framework published on HuggingFace and GitHub. LTX Studio, the platform built around it, is not open source.
How do I know how many credits I have left mid-project?
The current credit balance shows at the top of the LTX Studio interface and updates in real time immediately after each generation.
Can I switch plans partway through a subscription?
Yes. Upgrading takes effect immediately with a prorated charge for the remainder of the billing cycle; downgrading only takes effect at the end of the current cycle.
What happens to my subscription if I cancel?
Cancelling stops future billing but leaves the current plan active until the end of the billing period already paid for, so nothing is cut off mid-cycle.
Do I need any prior experience to get a usable result?
No prior experience is required to start generating, though the more advanced tools — Flows automation, LoRA training, IC-LoRA reference transfer — assume some comfort with a more technical workflow.
Does LTX ever run discounts or promo codes?
Yes — the site states that discounts and promo codes are offered periodically, typically timed around new feature or model releases and at various points in the year, particularly on yearly plans.
