I need help of error video in half life source

[Heisemberg]

I've been wanting to make a machinima or at least a short video with the motion blur used in Freeman's mind for a while now, and I've done Ross Scott's steps and other instructional videos, but I don't know if this is part of the process or if I did something wrong, but when I saw the recording I made in half life source, the video started to look broken, if anyone has a solution or knows about these things, write it below
