Identification markers that follow an item, a person, a vehicle throughout the period of the footage

We have purchased licenses for Camtasia for the Police in the UK. With respect to video edits we do we currently have to pause the screen 5 seconds to identify an individual, vehicles which are then viewed with the CCTV footage throughout. It would be great evidentially if we were able to place an identifying triangle above the vehicle which then followed them smoothly across the footage. We have seen other editing products which can do this and this would be an ideal addition to the editing program if this was possible.

have you considered using animations to track the identifying triangles?

Kayakman, I wish I had just 1% of your imagination.

I think Granville is looking for something a little different though: ID an auto in CCTV video of street traffic and be able to automatically follow it  - say with a "glowing" triangle, something easy to spot.
Could "Facial Recognition" software might be adapted to tracking "an auto" instead? If autos are as distinguish-ably as faces, why not But therein is the problem, unless they're tracking the BMW with roof damage . . .
Remember "The Thomas Crown Affair"?

thanks for the compliment, Ed

I had figured he was looking for the functionality as you describe

but my guess is that the coding to accomplish it would get very tricky and complex, due to the need to address possible extreme dynamic changes in a target's aspect [like approaching from far off with left side in view, then transitioning to receding with right side in view], especially if the action occurred very quickly ??

but no doubt it would be a great feature to have

Yes coding it is one thing and success . . well??  Facial recognition is fairly mature and it doesn't take identical twins to go wrong. So, like you, I to think it would be a great feature, beyond tracking the bat-mobile thru London may be impossible at least for now.

My suggestion to the UK police would be. If you want to do a lot of this. Get an inexpensive program with motion tracking. Create your animations there and it could save many hours of your time. Making you grateful you did so.

You can get basic motion tracking in a lot of inexpensive video editing programs.

It tracks fairly well but can go off target if the motion becomes too fast or the target jumps to quickly. But if you don’t set your expectations too high. You can get some satisfactory results out of programs that cost under one hundred dollars. And I’m talking about full video editing programs loaded with features, audio capabilities, video stabilization, blah blah blah.


If you want first-class motion tracking. That doesn’t come so cheaply. And is much more labor-intensive to work with. But you can accurately place things in a scene with pinpoint accuracy regardless of how much camera motion there is.

I don’t care much for working with manual motion paths in Camtasia. There a bit labor-intensive, unless what you’re tracking goes in a straight and at a constant speed. Because Camtasia doesn’t use conventional key framing, which gives you far more control.

 Regards, Joe

Thank you Joe. This is the type of thing we are looking for it would be good if motion tracker was built into Camtasia as an editing tool. It would make it a more attractive editing program. I find Camtasia simple to use but this would really make a difference within the professional back ground as well as for the private home use.
