Honestly think i did better this time..

include programs used in the post

Try using keyframes to set a path for the freecam instead of moving it manually, it'll look much smoother

If you -have- to use the trial version of fraps you can try to crop out the top part of the video

try using /opt blood 0 and /opt bloodstains 0

I think it looks much better

try to make video on high(the quality),it make it looks more cool.
practice to sync and some effects too.
as skip said,if you have a watermarked version of a recording program,pancrop to remove it.

Use OBS, its free, maximum quality, simple, no ugly watermarks.

Thanks for the help guys. I'm new to this so i'll try doing these in my later vids

You should. SHOULD!
Work on your keyframing usage skills. This is pretty much to do a very good video.
Just use this keyframing like every 200 frames to make it slow, and 100 to make fast moving camera. I cant explain it. You just need to figure it out.
