I’m brand new here and would first of all like to say hello to everyone!
But I also have a question: I make music, and I use Shotcut to process video recordings made with 2 or 3 action cams into small videos that I upload to various social media platforms.
My question: I would like to create a video in which I play several instruments at the same time. So I would set a camera to a fixed subject and record myself playing the drums, guitar and keyboards in this setting, one after the other, so that my movements don’t overlap. So far, so good.
Can I use Shotcut to merge these three scenes into one so that it looks like I’m playing all three instruments at the same time?
Yes, you can do it with Shotcut.
You just need to use a mask filter on each tracks above the first track.
Example (with 3 instruments):
Track V1: You are in the center of the screen
Track V2: You are of the left side of the screen
Track V3: You are on the right side of the screen
The clip on track V1 doesn’t need a Mask filter.
You only need to use a mask on the two other clips.
Your choice of Mask filter depends on the complexity of your scene layout.
For a simple layout (like in my video below)
The Mask: Simple Shape will be enough.
If you need to create more complex masks, you may need to use Mask: Draw (Glaxnimate)
Here’s a very simple and quick example. I didn’t have time to a more detailed video. But maybe this will be enough to get you started.
