Really need some more information.
Are you playing modded minecraft or vanilla? What software are you using to record?
Some programs will limit minecraft to 60fps if that's all it is recording.
What recording software are you using? If you have it set to record at a certain FPS it may not let your game run beyond that
That's because your recorder can only encode/live record 60fps real time. Besides Youtube will slow it down to 30fps. Nothing you can do for a fast video.
Try other recording programs such as Bandicam and see if you still get the same issue.
