All I'm after is the ability to track motion with a line.

Actually, I'd say each is faked in a different way.
What do you mean by "faked"? I manually motion tracked my example. Aviutl has an automated tracking filter, but I have yet to figure it out, so I did it manualy.
Here is the project file if anyone is interested. You can make the line any size and color:One man's opinion is another man's toilet paper.......
BTW, although free, I agree Aviutl is very capable -- you know that better than anyone!
It's because the original YT's "slow mo" version is done with duplicates, not real unique frames. I think in aviutl, instead of setting it to "tweening" (it creates "inbetween" motion) you can select one of the other interpolation options so it moves stepwise like that original version if you wanted to . (Or do the same thing with the normal speed, non duplicate version, then duplicate the frames)
The motion blur on this clip on some of the frames (even though some of is probably from YT compression) would make it difficult to automatically track . You'd probably have to correct some points or manual assist
For sports analysis scenarios, you always want to shoot with fast shutter speeds to reduce the motion blur

Edit: So you've split the object and just replaced it. For the video I'm trying to track motion this will be a very difficult and long process. Can I track the pixels instead? Also the object is tracking the hands manually but how do i get the line as with your video?

This one was done on the normal speed section, it's a lot smoother / better I think.One man's opinion is another man's toilet paper.......
@ Mordecai0, I'm not in the mood to make another tutorial. I did cover "mid-points" (aka key-frames) in my advanced editing tutorial. You should check it out. Basically you add new custom object, place it where you want. Right-click to add "Mid-Points" to animate.
Maybe if I have some free time, I'll make a tut and put it in the other thread for Aviutl tips, tricks and support.One man's opinion is another man's toilet paper.......
A very simple automated tracking example with AviUtl (see attached video demo)
1. select the video segment where the feature/object appear inside the video (exclude those get outside the screen)
2. Check "English EXO"
3. Select feature points
4. Deactivate plugin
5. Click ANALYZE
6. Close file
7. Load video into Adv.Editing
8. Load tracking#.exo
9. Goto scene, enable alpha channel
10. switch object type, tune parametersAviUtl i18n, plugin developer.

Thanks MaverickTse for the detailed tut. Yes the Automated Motion Tracking works pretty good.........One man's opinion is another man's toilet paper.......
