Step 2. Prepare your video file by uploading it to Google Cloud Storage or providing a publicly accessible URL.

Step 3. Use the Speech-to-Text API to transcribe the audio from the video into text. You can make API requests using the client libraries provided by Google Cloud or through RESTful API calls.

Step 4. Process the transcription results to create subtitles. This may involve segmenting the text into appropriate chunks, adding timestamps, and formatting the subtitles according to your requirements.

Step 5. Save the generated subtitles in a suitable format, such as SRT (SubRip Subtitle) or VTT (WebVTT), which are widely supported by video players.

Step 6. Associate the generated subtitles with your video by either embedding them directly into the video file or providing them as a separate subtitle file during playback.
