How to Install Subvert on Your Synology NAS

With Subvert you can generate subtitles, chapters, and summaries of MP4 videos in seconds with the help of OpenAI. Your video is sent to an API where the audio will be automatically extracted from it using FFmpeg, and then sent to OpenAI’s Whisper model for transcription into the common VTT format. Subvert requires no persistent volumes so you can start to use it immediately. Starting with version 1.0.5, you also have the ability to upload audio files in addition to video files. In this step by step guide I will show you how to install Subvert on your Synology NAS with Docker.

💡Note: This guide works perfectly with the latest Subvert v1.0.9 release.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
