Is there TRACK MATTE KEY effect for Blender Video Sequence Editor? I use this effect for Videos in Adobe Premiere Pro for Overlay Transitions of .MOV files. Not knowing how to do in Blender, I used Blend modes for these effects, but they don't work exactly as desired like with Track Matte Key effect.

Thank you, Bhat


You need to work "effects" in the compositor. It seems you need to track and key at the same time. If this is the case, you will first need to address the track (movie clip editor), once you generate your 8 obligatory tracking points, you can attach whatever you need, then use the 3D space to "stick" your motion graphics plane (or .mov), and finally go to the compositor window and now work the part of the keying. enter image description here Ian Hubert shows different techniques that might be helpful to your workflow here: https://youtu.be/RxD6H3ri8RI

If you need further assistance with your question, please let us know. Thanks!

    $\begingroup$ No, there is no need for an obligatory number of tracking points. Unless you are doing 3D reconstruction, you don't have to solve the scene, so there is no need for a specific number of trackers. To automate mask creation you can use motion tracking and use the tracking information in 2D either by using in the compostitor or controlling vertices in the 3D environment. Trackers can be associated with control points of mask to facilitate rotoscoping or "Tracked Matte keying". $\endgroup$

  • $\begingroup$ I will post a example with a video of Overlay transitions for Premiere Pro. It is a less than 3 min. video first with examples and then how Track Matte Key is used for Overlay transitions. youtube.com/watch?v=qfXfEi_VsGc $\endgroup$ Oct 5 '20 at 5:37
