JokerVenom This problem is faced by many, but hardly anyone talks about it,
Don’t worry, your video is working fine, if you open your task manager, and you skip the video timeline to some other point, you will see that if you have a gpu or only cpu for video output in vlc, the load will be high, it will consume 100% of it for some time, then after some seconds your video will work.
I know a fix for this, i.e. converting codec to h.264 using ffmpg, you can either search it online or ask here, if you have a gpu, search how to use that for fast conversion, then your video won’t lag.
