Multiple Media

The Multiple Media control allows a user to upload several image or video files at once.

The Multiple Media control is an input component that allows a user to upload multiple image or video files in a single step. The control then outputs a list of temporary URLs, one for each uploaded file.

When to Use

Use the Multiple Media control for any workflow that needs to process a batch of files provided by the user. Common use cases include:

• Compiling multiple video clips into a single highlight reel.

• Analyzing a collection of images.

• Processing a set of related documents or slides that are in image format.

How to Add

1. From your workflow's Build page, click on + Add Input.

2. Select Multiple Media from the list of available controls.

Configuration

• Title: The main label for the file upload area.

• Description: Optional helper text to provide more context.

• Variable Name: The name used to access the list of URLs for the uploaded files.

• Optional/Required: A toggle to specify if the user must upload at least one file.

Accessing the Value

This control outputs a list (or array) of strings, where each string is a temporary, secure URL pointing to one of the uploaded files. This list is accessible via the variable name you assigned.

For example, if the variable name is source_files:

• The value of {{source_files}} would look like ["https://url/to/file1.jpg", "https://url/to/file2.png"].

• This list is ideal for use with a Map Node, which can run a sub-workflow for each file URL.

Note: For security, these URLs expire after a few days. They are intended for immediate processing within the workflow run.

Example

Goal: Allow a user to upload several product images and generate a description for each one.

1. Add a Multiple Media Control:

   • Title: "Upload Product Images"

   • Variable Name: product_images

2. Add a Map Node:

   • Input List: {{product_images}}

   • Sub-Workflow:

     • Sub-Node 1: OpenAI MCP (GPT-4 Vision)

       • Action: Analyze Image Content

       • Image URL: {{item}}

       • Prompt: Write a one-sentence marketing description for the product in this image.

       • Note: {{item}} refers to the individual image URL for the current iteration.

3. Add a Save to File Node:

   • File Name: product_descriptions.txt

   • Content: The collected list of descriptions will be saved: {{map_1.output}}

This workflow efficiently processes a batch of user-uploaded images, performing the same analysis on each one and collecting the results.
