    Quadcopter and Betaflight cheat sheet

Introduction

On my yourney though hundreds of videos, tutorials and manuals (Bardwell, UAV Tech, JohnnyFPV, Mr. Steele, Le Drib, RotorRiot (sorry, for the missed ones) and wrote down their suggestions). This is the result of my notes. It should provide the least necessary but most compressed information to start tuning and setting your Quadcopter.
In my case I use the widely spread Taranis X7 remote control.
I am a freestyle pilot, so keep in mind, that these settings are in this scope (more smooth, softer flight behaviour).

                Easy way to convert MKV to MP4 with ffmpeg
              
          
    Converting mkv to mp4 with ffmpeg

Essentially just copy the existing video and audio stream as is into a new container, no funny business!

The easiest way to "convert" MKV to MP4, is to copy the existing video and audio streams and place them into a new container. This avoids any encoding task and hence no quality will be lost, it is also a fairly quick process and requires very little CPU power. The main factor is disk read/write speed.
With ffmpeg this can be achieved with -c copy. Older examples may use -vcodec copy -acodec copy which does the same thing.
These examples assume ffmpeg is in your PATH. If not just substitute with the full path to your ffmpeg binary.
