Automatic motion tracking

Open raindropsfromsky opened this issue 1 year ago • 5 comments

Shotcut has an amazing feature: automated motion tracking.

This video shows the different modes of motion tracking. Here is another demo.

Very useful feature!

Wow, that is a great feature. I wonder if the current "Tracker" effect is something that can be enhanced to provide similar functionlity.

This sounds like a complicated enhancement and will take time to develop.

Note that we can think of this feature in two different parts:

  1. The algorithm that creates the tracker information (it determines the size and position of the bounding box for all frames). Different algorithms have different success in tracking moving objects with blurred/changing outline.

  2. The algorithms that allow the user to place an object vis-a-vis the bounding box (BB for short). Options:

    1. Placed in the middle of the BB, but without scaling up/down
    2. Placed at a fixed offset distance from the BB center,
    3. Placed inside BB, and scaled to fit the BB

Hello @raindropsfromsky The Tracker effect has been greatly enhanced to provide some but not all the functionality enhancements listed here.

It would be great if you have time to kick the tires and provide some feedback.

You will need to download the latest dev daily build from openshot.org/download/#daily.

Hello @raindropsfromsky Did you get a chance to try the updated Tracker Effect?
