impartus-downloader VS sickbeard_mp4_automator

Know nothing about it, but after googling a little, I got this: https://github.com/paljsingh/impartus-downloader

I have been using MP4 automator for over 5 years; https://github.com/mdhiggins/sickbeard_mp4_automator . I choose MP4 as it works on preety much any device i have ever tryied, H264, AAC stereo and AC3 5.1. Have also used Tdarr for H265 conversion; it really uses 35-50% less space for same quality (4k and I wasnt able to see difference).

SMA, Automatically converts media files to a standardized format, and tags them with the appropriate metadata from TMDB if the container supports tagging. Made to integrate with Radarr, Sonarr, etc. but can be run stand alone. Python required (3+, although 2.7 was still supported, last I knew). Free. https://github.com/mdhiggins/sickbeard_mp4_automator

Sickbeard mp4 Automator for media conversation and metadata matching. Combined with mediaelch for bulk renaming and poster downloads, they’re essential for plex hosting. Also use subler for quick metadata/language code fixes.

Browsed to /usr/local/sma/postSonarr.py and clicked the test button, and I got an error that the script exited with -1. I am wondering if it has something to do with this weird instruction from the github page:
