Replay Mod Forums

Hello,
Recently I was rendering a video out. It finished the process successfully, but when I went to go play it in mp4, I received this :

I'm using :
Forge : 1.12.2-14.23.3.2655
Optifine with Shaders like a mod : 1.12.2_HD_U_D3
ReplayMod like a mod: 2.1.3

Does the preview look fine during rendering? If so, then this is probably a bug in ffmpeg or one of its encoders. In that case it might help to switch to a different Encoding Preset and convert it to your format of choice at a later time using a video editor of your choice.

The preview is fine during rendering. So I have to change the conversion format ?
I tried with the custom bitrate instead of mp4 high quality and it works. Can you explain me what are the mbps for a video ?
