Guides on JSON-to-video, AI generation and automation pipelines — straight from the team building SamAutomation.
Three themes run through everything here: rendering video from data instead of an editor, captioning at volume, and what each platform actually allows you to automate. Start with the JSON-to-video guide, the video API comparison or the TikTok pipeline in n8n.

The official Creatomate API video automation documentation is an online reference, not a separate download. It covers authentication, render jobs, templates, webhooks and errors. Access to the documentation is free. If you need an offline PDF, use your browser’s print-to-PDF function and check the live documentation again before implementing anything.
A basic render request sends JSON to https://api.creatomate.com/v2/renders. Add your project API key as a Bearer token, then provide either a template_id with modifications or a complete RenderScript source. The response identifies the render job so your application can poll its status or wait for a webhook.
For a platform-neutral example of payloads, assets and render jobs, follow the JSON-to-video API workflow.
There are two different text-to-video workflows. Generative models create new moving images from a prompt. Template renderers place text, images, clips and audio into a controlled timeline. Use a model when visual invention matters. Use templates when timing, branding and repeatable output matter.
To convert text into an animated video, split the script into scenes, assign each scene a duration, create or select its visual, add narration, then render captions and transitions. A template-based pipeline gives you predictable layouts. A generative pipeline gives you less predictable but more original footage.
The best AI for text to video depends on the job, available models and the amount of control you need. Compare prompt support, image-to-video input, output duration, resolution, latency, content rules and API access before choosing.
You can compare current model inputs and output options in the AI video model directory.
SwarmUI is a local interface that can run supported video models through its configured backend. A SwarmUI tutorial starts with installing the application, opening the Generate tab, selecting a compatible SwarmUI Video model, entering a prompt and setting the video parameters exposed for that model.
The SwarmUI model downloader helps place supported files in the expected model folders. You can also download a model from its official repository and save it in the folder named by the SwarmUI model-support documentation. Model files can be large, and the right format depends on your backend and available memory.
SwarmUI presets save a group of generation parameters so you can reuse them. Treat a preset as a starting point, not a promise of identical results across models. Parameters supported by one architecture may do nothing or cause errors with another.
SwarmUI can extend video with the <extend:frames> prompt syntax and an image-to-video model. You must also configure the Video Extend parameters, including a compatible extension model. The project describes this feature as experimental, so expect continuity problems around motion, subjects and scene edges.
For a SwarmUI text to video download, generate the clip first and use the output controls to save the rendered file. If you mean downloading the model, use the model downloader or the repository linked from SwarmUI’s current video-model documentation. Menu labels and supported formats can move between releases.
If local hardware is the bottleneck, an AI video generation API lets you submit jobs without maintaining the model runtime yourself.
Good API documentation starts with one working request. Show the base URL, authentication header, smallest valid body, response, job-status flow and a real error. Then document every field, its type, whether it is required and any accepted values.
Keep the examples executable and version them with the API. An OpenAPI file is useful for generated references and clients, but it does not replace a short quick start that explains the complete request-to-result flow.
Make API documentation is available in the Make Developer Hub. It documents the REST resources, authentication tokens, scopes, pagination, errors and API reference. Check the documentation for your Make zone and current release before copying an endpoint into production.
For an automation example built around video jobs, use the n8n video automation setup as a practical reference.
The documentation is free to read, but ongoing API rendering is not a permanently free service. Creatomate may provide trial credits before you select a paid plan. Plans and included credits can change, so check the current pricing page.
Create an account, open a project and find its API key under Project Settings. Trial credits may let you test that key without paying first. Keep the key on your server and never expose it in browser code or a public repository.
Creatomate uses monthly plans with included rendering credits, storage and usage limits. Video consumption depends on properties such as duration, resolution and frame rate. Tariffs and plan allowances change, so calculate your expected renders with the current pricing documentation.
Open the template inside your Creatomate project and copy its ID from the template or API example. You can also retrieve templates through the API and read the returned id. Send that value as template_id when starting a template render.
The official quick start sends a POST request to the renders endpoint with a Bearer API key and a JSON body. A template render includes template_id and any element modifications. Use the live online documentation as the source because endpoints and fields can change.
The official reference is maintained online. If no current PDF is offered, save the relevant pages with your browser’s print-to-PDF function. Recheck the online version before shipping code because a saved file can become outdated.
There is no single best model for every job. Compare visual quality, prompt control, image-to-video support, duration, latency, hardware needs, API access and usage rules. Test the same prompt and settings across your shortlist.
Choose a model listed in SwarmUI’s current Video Model Support documentation and match it to text-to-video or image-to-video. The practical choice also depends on your backend, memory and acceptable render time. Start with the documented defaults for that exact model.
A preset stores reusable generation parameters. Apply one, inspect every value and adjust settings that do not fit your selected video model. You can also reference a preset from supported prompt syntax with <preset:name>.
SwarmUI supports experimental video extension through <extend:frames> and the Video Extend parameter group. It requires a compatible image-to-video model. Expect visible continuity errors and test short extensions before attempting a longer sequence.
Use the Make Developer Hub at developers.make.com/api-documentation. It includes getting-started instructions, authentication, scopes, pagination, troubleshooting and the endpoint reference. Use the base URL for your Make zone.
A few providers offer trial credits or limited testing, but there is no universal free rate for sustained generation. Billing may be per execution, operation, render minute or credit. Self-hosting removes the provider fee but still uses your own compute, storage and bandwidth.
