I suggest you find some other way to highlight perhaps by using an image of a color circle with transparent background on a track above and using the Size, Position, and Rotate filter to place it. This is not going to be easy if you want to highlight every click in a screen recording. add Size, Position & Rotate to change the sizeĪnd the above does not add the darkening of the background video while highlighting.add Crop: Rectangle and set its Padding color transparent, adjust to the highlight area.with the copied clip selected, trim to just the time where you want to zoom in.Oh, I just watched that video, and I was assuming a different meaning for the question. I suggest watching some tutorials to learn about that. From there you need to use Keyframes to animate the zoom-in.
Click, hold and drag it to change the position. When the filter is active and the playhead is over the clip with the filter, there is a circle in the middle of the video. You need to use the Position part of Size, Position & Rotate. To crop a square of 100 pixels (so both the width and height of the cropped region is 100 pixels) from the center of input.mp4 video, you could specify only the input area size of 100x100 (since the FFmpeg crop filter defaults to the center if the x and y values are not specified), like this: ffmpeg -i input.mp4 -filter:v 'crop100:100' output.
