Instagram Video Transcriber with Gemini

This Apify actor uses the Google Gemini API to transcribe it. It's built to be robust, automatically handling video-to-audio conversion and compression.

Key Features

• Direct Transcription from URL: Simply provide a public Instagram video URL.
• Powered by Google Gemini: Leverages Google's powerful generative models for transcription. The default model is gemini-1.5-flash.
• Automatic Audio Handling: The actor automatically extracts the audio from the .mp4 video and compresses it to an .mp3 format suitable for the API.
• Advanced Control: Customize the output with optional parameters like a custom prompt and temperature settings to guide the model's output.

Cost of Usage

This actor uses two services that may have associated costs:

1. Apify Platform: You will be charged for Apify Compute Units (CUs) while the actor runs. The consumption is generally low for this task, as it primarily waits for API responses.
2. Google AI Platform: The primary cost will come from the Google Gemini API. You must provide your own Gemini API key, and you will be billed by Google for the API usage. For the most current pricing, please refer to the Google AI Platform Pricing Page.

Input Configuration

The actor requires the following input configuration.

Field	Type	Description
instagramUrl	String	(Required) The full URL of the public Instagram video you want to process.
geminiApiKey	String	(Required) Your secret API key from Google AI Studio. It's highly recommended to set this as a secret environment variable for security.
model	String	(Optional) The Gemini model to use. Defaults to gemini-1.5-flash.
prompt	String	(Optional) A text prompt to guide the model's style or to correct specific words and acronyms that are often misrecognized. Example: "Transcribe the following audio:"
temperature	Number	(Optional) A value between 0 and 1. Higher values (e.g., 0.8) make the output more random; lower values (e.g., 0.2) make it more focused.

Output

The actor will save its results to the default Apify dataset. The output is a JSON object that contains the model used and the transcribed text from the Gemini API.

Example Output

[{
  "model": "gemini-1.5-flash",
  "result": "This is a test of the Instagram transcriber."
}]
