Nice job!
By the way it seems that the cursors are not recorded properly, i initially thought that was a problem related to my old rig or Bandicam but after watching your videos that's not seem the case here.
That's kinda odd since they actually are visible in-game...at this point i really don't know if this problem is related to Med2 or to any recording software recording Med2...
.
Nevertheless, if you want to get rid of that annoying background noise may i suggest you to use audacity?
I always did have noisy microphones and i kinda learned how to get rid of that noise almost completely by now.
Now let's pretend that the .mp4 file is your next walkthrough.
As you can see i already have extracted the related audio file from the video, i usually use a third party program for that but actually you can do that with Audacity too: file-import-audio-open.
The problem is, Audacity come out with
default video libraries and it will not extract audio from .avi or .mp4 unless you update the libraries like this: edit-preferences-libraries-FFmpeg download.
But since the download and install of that libraries it's kinda tedious i do really think you should just stick with a third party program for extracting the audio.
Now extract your audio as a .wav file and just select and drop it into Audacity or open it, there will be a massage about the file, since you have the original video as a backup just choose "faster" and click ok.
Now your Audacity should be look like this or just a bit more spiky than that.
You now need to find a specific part of the track that contains the background noise only, so click on play and found it.
Now let's say that you found the noise part there, the first thing you wanna do is zoom in until you need it.
Now click and hold until you have select the noise part, it should be look like this.
Now go to effect-noise reduction-get noise profile.
Now zoom out until you are able to see the entirety of the track and then select all of it with ALT+2 clicks, it should be look like this.
Now all you have to do is return to effect-noise reduction and this time click on ok.
After the elaboration you can play again the track to make sure that everything is fine and after that you have to go to file-export-as wav.
And finally you just need to take the new track into your video editor along with the original video, mute the old track, merge the new one and finally export the video with the new audio!
It kinda feels complicate at first but when you get the hang of it this program will improve your audio quality a lot!
EDIT: After some testing i found the solution for the cursors not being recorded properly, it seems that most of the recording software come with a default option set to NOT show any cursor in-game so all you have to do is search that option and set it as show cursors in-game!
