How to do dimming - dimness - pointer?

Like in a videos below


23s; 28s
or

17s; 34s

That would help me a lot.

Very easy. Either 1- use a plugin that does that (easy to create if you know the basics of Motion),
or 2- stock two copies of that clip on top of each other. Lower the opacity of the bottom clip. Place a mask on the top one, position it correctly, feather the edges.

… easy (Mr Wolsky taught me this trick) :

• select the clip in your project
• in the Inspector, select Mask for Color Correction
• in the Color Board, select 'Outside'
• dim brightness ...

to make the highlight appear, you have to create a secondary ....

wow, that is awesome, thank you! Stunning effect and so easy to do when you know how

"to make the highlight appear, you have to create a secondary ...."
... what did you mean, secondary file just for this effect?

Any settings in the Color Board are not keyframe-able. Yet! <fingers crossed for future versions>

so, if you want to make a soft dissolve, grab'n drag your clip from the storyline while holding the alt-key = doubles the clip. Apply to the top one the effect mentioned before. cmd-T, secondary fades in and out, and the highlight fades in and out … 

Another really simple way to do this: use the Censor effect. Select Method>darken and check Invert. Adjust Amount to suit. The nice thing is all of this is set up to keyframe too so it's easy to follow your subject.

Enjoy!

Guys,
I got to say you are awesome!

Karsten, your trick is briliant, thanks to that I can show different shapes like one line or columne in a table.

Squamish ed, the Censor effect is so easy and quick!

Fantastic! Thanks a lot!
