How to run RenderTune locally:

  • Clone this repo and cd into the folder.
  • Run npm i and npm i -g electron if you haven't already installed electron globally.
  • If you are on windows I recommend using command prompt, as that can launch electron apps fine, while Windows Linux Subsystem has troubles launching electron apps.
  • If you are on a mac using the mac terminal, download brew and ffmpeg-mac/ by following the instructions below.
  • Download and setup ffmpeg-mac/ folder (instructions below).
  • Run electron . to start the program.

How to install ffmpeg locally for mac (ffmpeg-mac/)

  • If you are on mac; run sh to create the ffmpeg-mac/ folder and statically build a version of ffmpeg that can be sandboxed and distributed to the mac apple store (mas).
  • Verify your local ffmpeg-mac/ folder has no dynamic libraries by running this command: otool -L ffmpeg-mac/ffmpeg | grep /usr/local
  • If any files show up after running this command, delete or move those files, redownload the ffmpeg-mac/ folder, then run the 'otool' command again to verify there are no dynamic libraries in your local ffmpeg-mac/ folder.

Releasing a new version:

  • Change version number in package.json (this is the bare minimum to change).
  • Make sure you have local vars set for GH_TOKEN, APPLEID, and APPLEIDPASS.
  • Mac:
    • Download and setup ffmpeg-mac/ folder.
    • Mac Apple Store: Change package.json mac build targets to only contain "mas", verify the paths in are correct, then build & sign by running the command npm run build-mas. Upload the outputted RenderTune.pkg file to App Store Connect using Transporter, then create a new Mac Apple Store submission for review.
    • Mac .dmg Installer (auto-updates): Change package.json build targets to contain "dmg", "zip", remove the RenderTune.pkg file we crated for MAS in the above step if it exists since we don't want to package that inside our build. Build & publish by running the command npm run build-mac-publish.
  • Windows:
    • To sign a .appx build for the Windows Store you need to have a Windows SDK downloaded:
    • Windows Installer (auto-updates), Windows Portable, and Windows Store .appx: On Windows, make sure env vars are set by running echo %GH_TOKEN% in command prompt terminal, build nsis-web/portable/appx targets with the command npm run build-win-publish. To sign the Windows Store Build, make sure you are on a computer with the powershell electron-windows-store requirements, and then run the following powershell command to generate a signed .appx file that you can upload to the Microsoft Store review system:
electron-windows-store --input-directory C:\Users\marti\Documents\projects\rendertune-v0.5.0\dist\win-unpacked --output-directory C:\Users\marti\Documents\projects\RenderTuneAppx --package-version --package-name RenderTune --package-display-name 'RenderTune' --publisher-display-name 'martinbarker' --identity-name 1845martinbarker.digify -a C:\Users\marti\Documents\projects\rendertune-v0.5.0\Resources\
  • Linux:
    • Login to snap store from terminal: $ snapcraft login. Build & publish linux builds for snap and AppImage: $ npm run build-linux-publish. This will output a .snap file in the dist/ folder that you can upload using the command: $ snapcraft upload --release=stable dist/rendertune_0.3.23_amd64.snap (make sure your .snap filename is correct).
  • Once all of the following steps have been followed, there should be a new RenderTune version drafted on GitHub with files uploaded for Mac, Windows, and Linux.


This list is of future updates / improvements I plan to make for RenderTune (If you can think of any features you would like, contact me and I will include them in the roadmap)

  • UI Improvements: Better render status options, more efficent code.
  • Add API to electron app so you can trigger renders using POST route.
  • New Feature: Append/Prepend video file to video we are rendering (Add MP4 intro/outro, add MP3 intro/outro)
  • New Feautre: Record, split, export and tag audio files.
  • New Feature: Upload files to YouTube / tag
