ughhh recording with ffmpeg is so confusing. I'm trying to do it with HLAE (half life advanced effects) and I think its working fine but i have no idea how to stitch together the files that come out of the recording

then I tried it with this open source program called ShareX and for some reason the video recording is laggy as fuck I can't seem to get it to work

im just so lost but there is no way im going back to recording with shadowplay

if anyone knows how to use ShareX and can help me thatd be appreciated.
