I'd like to share a cool effect I've obtained using mostly internal resources (except for one single PNG used for masking).

You can see the final result here: https://streamable.com/9p0wk9

It was quite tricky to figure it all out. I don't know whether there's a simpler way to obtain the same effect, especially if you really want a fine control over the animation via the autos (as I do).

Unfortunately, I don't have time to make a video tutorial, but if anyone is willing to make one, please do and share freely!

I'm uploading a tarball with all files here, please consider it to be public domain.

Here is a commented layout scheme of my setup. You can also find a screenshot of my timeline window in the tarball.

Enjoy!

Effect layer 4

UNDERLYING VIDEO (shared track)
Title (the first text shown)
Effect layer 3: Reroute (shared effect)

Effect layer 3

Effect layer 2 (shared track)
Sketcher (a white rectangle covering the part of the screen from which the highlight emerges)
F_chromakey (be sure to fine-tune it to remove any unwanted edges)
Reroute (settings: Target track: Top - Operation: Alpha replace)
-------------------------------------------------
Effect layer 2
- uncheck the MUTE button (i.e. don't send to output) and (optionally) the PLAY button in the patchbay -

- animate using CAMERA AUTO -
-------------------------------------------------
Effect layer 1

Sketcher (highlight color - may cover the entire frame or less)
Title (the second text shown - the one with highlight)
-------------------------------------------------
UNDERLYING VIDEO (the position of this track is irrelevant)
- uncheck the MUTE button (i.e. don't send to output) and (optionally) the PLAY button in the patchbay -

You may use this track to host shared tracks if you want more than one track to play under the animated title effect.
Just stack the remaining tracks anywhere, share them here and uncheck the MUTE button on each of them (possibly keyframe it to allow them to be seen in other parts of the video).

Is it better to use Blender?
