qTool User Manual
qTool is a collection of supporting scripts makes command line tools such as FFmpeg easier to use.
Since early 2015, I was using ffmpeg frequently for compressing online videos at work. To save myself some time, I made a droplet script so I can just quickly drop a video on it to make a compressed mp4 without typing any codes.
Over the years, that one script became many, it expanded from supporting FFmpeg to other tools like ImageMagick, Youtube-dl and even 3D rendering app such as Redshift. It came to a point when I decided to publish these scripts on the internet, hopefully to benefit other graphic artist like myself as well as encouraging me to make the scripts better.
You probably are wondering what is benefit of using FFmpeg verses using a commercial video transcoding applications such as Adobe Media Encoder. The answer is — it is much faster, more versatile, more controls!
However, qTool was never meant to be a replacement for AME, there are certainly times people including myself prefer tools with graphic interface over scripts. In fact, to fully utilized these script, you will need modify with codes within, and learn a bit of scripting.
Here is a breakdown of some of the key features of qTool.
