Frequently asked questions
What is programmatic video editing?
Programmatic video editing means using code and software tools to automatically generate or modify videos. It lets you create large volumes of personalized and data-driven videos by controlling video templates and assets through APIs or scripts, often integrating with tools like After Effects.
How do I create videos programmatically?
First, you create your video template in After Effects. Then you upload this template to the platform and, using an API, you connect your data, like spreadsheets or databases, to the template. The API applies your data to the video layers and triggers cloud rendering to generate videos automatically without manual editing or exporting.
Why use programmatic video editing?
Programmatic video editing speeds up production by automating video creation, reducing manual work and errors. It mass creates data-driven videos by connecting data to templates, making it perfect for marketing, video localization, and content teams who need fast, consistent, and scalable video output.
What types of videos can be edited programmatically?
You can edit a wide range of videos programmatically using Plainly. This includes personalized marketing videos, product demos, social media ads, event highlights, and localized content. Any video built with After Effects templates that requires data-driven customization can be automated through Plainly’s platform.
Do I need to know After Effects to use Plainly’s API?
No, developers can work with the API without touching After Effects. However, your video templates do need to be created in After Effects. Once the template is ready, everything else can be automated via API. You can also contact our team if you want us to create a template for you.

Yes. Plainly’s API is designed for easy integration with your workflows, databases, and marketing platforms to automate video production. It can also integrate natively with various tools like Google Sheets, Dropbox, and more.

Working with Plainly was great, their API is robust but simple to set up. After setting up the workflow, we literally forgot about it. The integration with After Effects allowed my team to work with tools they are familiar with and create high-quality video templates.

CTO, Tapni
Plainly allows you to produce large amounts of video content very quickly. A great advantage is that your content can be still very individual and on-brand due to the ability of using Templates made in Adobe After Effects. Its interface is quite intuitive and the software gets new interesting features often.
