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.
Install Container Manager via Synology “Package Center”. If you run an older DSM version (under 7.2), search for Docker instead of Container Manager.
Log in to your OpenAI Platform. At the top right of the page, click Personal then View API keys. Follow the instructions in the image below.
Click Create new secret key. Follow the instructions in the image below.
Save your own API Key somewhere secure because you will need it later at STEP 7. Follow the instructions in the image below.
Go to Control Panel / Task Scheduler / Create / Scheduled Task / User-defined script. Follow the instructions in the image below.
Once you click on User-defined script, a new window will open. Follow the instructions below:
- General: In the Task field type in Install Subvert. Uncheck the “Enabled” option. Select root User.
- Schedule: Select Run on the following date then select “Do not repeat“.
- Task Settings: Check “Send run details by email“, add your email then copy paste the code below in the Run command area. After that, click OK.
docker run -d --name=Subvert \ -p 5478:8080 \ -e OPENAI_API_KEY=APIKEY \ -e UPLOAD_MAX_FILESIZE=1024M \ -e MEMORY_LIMIT=1024M \ --restart always \ aschmelyun/subvert
Note: Before you paste the code above in the Run command area, change the value for OPENAI_API_KEY and add your own API Key that you have previously generated at STEP 5.
After you click OK on STEP 7 a new warning pop up window will open. Click OK.
After you click OK, type in your DSM Password then click Submit. Follow the instructions in the image below.
After you click Submit on STEP 8, select your “Install Subvert” Task then click the “Run” tab. You will be asked to run Install Subvert – click OK. Follow the instructions in the image below.
Go back to STEP 1 or you will deal with karma 🙂
The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://Synology-ip-address:5478 Upload your own MP4 video or audio file. Follow the instructions in the image below.
Choose Subtitles, Chapters, Summary, Video Language, then click Start. Follow the instructions in the image below.
