RTSS: Help Manually complete Prerecord buffer So I'm using Afterburner and RTSS to do pre-record buffers of my games. Earlier the EncoderServer.exe crashed while I was trying to save off the current buffer to an MKV file. So now I have this *.mkv.prerecord file that I believe has the video/audio streams I want in it, but it's not a recognized format for extracting any of the media. Is there some way to manually convert/finalize this file to an MKV that can be viewed? Thanks for the help.
