So, basically i have done everything i can think of right. I have downloaded the Replay mod, the fabric launcher and the ffmpeg. I have made a folder in the (D:) disk, and i have copied the path from the bin into the left input of the command line settings. Here it is:
D:\ffmpeg\ffmpeg-20190923-8c90bb8-win64-static\bin\ffmpeg.exe
I have also run the installer.bat and it said that the installing of ffmpeg was succsessfull and that it was installed. But every time i click render i just keep on getting the same message:
Rendering Failed
To render a video, you need to have ffmpeg installed. http://ffmpeg.org
And its driving me nuts. I can't find anyone with the same problem, i just feel like there is no fix. I have been looking into this for way to long and i think it's actually driving me crazy! I have a video to upload on my youtube channel tomorrow and i need to get this fixed very soon! please help! (It would be much appreciated)
