At the 1:20 mark of this video, the author incorporates a line of sight marker to track the players line of vision. Any suggestions on how he did this? What software he might have used, etc?
I want to try and reproduce in some of my own videos.
Thank you.
It doesn't really look like it is actually being tracked. It looks like a manual overlay of a line on to it based on the head movement. It really doesn't look particularly accurate either from what I can tell. Something like Adobe After Effects (paid) or Black Magic's Fusion (free) can easily be used to accomplish this, though they do both have a learning curve.
I finally heard back from the Author:
"I use Adobe After Effects for the graphics in all my videos. The head tracker is basically a solid line with transparency set to about 50%. The rotation point on the line is moved to one end of the line, and then you place it on the player's head and set it to follow a null point. In some of the cases, I had to animate the line manually. It does take a bit of time, but it definitely highlights the point. Let me know if you need any other help. Good luck!"
