We should definitely up the motion blur when we’re recording the run.
mat_motion_blur_falling_intensity [0-?]
mat_motion_blur_falling_max [0-?]
mat_motion_blur_falling_min [0-?]
mat_motion_blur_forward_enabled [0-?]
mat_motion_blur_percent_of_screen_max [0-?]
mat_motion_blur_rotation_intensity [0-?]
mat_motion_blur_strength [0-?]
Just played with the settings and it feels awesome though sometimes a little unrealistic.
Hmm…I guess it’d look cool, but how annoying would it get at times?
What if you use motion blur only when recording the video; will that work?
You don’t have to play with motion blur on to have motion blur. 
Personally I love playing with it. My favourite combo at the moment is:
mat_motion_blur_forward_enabled 1
mat_motion_blur_percent_of_screen_max 15
mat_motion_blur_strength 3
Play without motion blur, then enable it during playback?
Indeed. But I still love playing with it on. It just makes me feel so god damn awesome. Might try playing surf maps TF2 with it on.
