Sometimes I see a photo of say, a cup of coffee and from that coffee is a constant animated rising of steam. Can this sort of thing be done in Shotcut? Yes, I know film a hot cup of coffee, but was wondering how that sort of effect is created on a photo.
Yes
I don’t think it would be as easy as filming what you want.
Hi Johny_Debt
I made the clip below with Shotcut:

You need a video-clip of white smoke on black background (found mine on YouTube).
In Shotcut, put this clip above the coffee cup photo in the timeline.
Apply the filter Blend Mode with the Screen setting to the smoke clip.
You’ll certainly also have to use the Size and Position filter to position the steam on the right spot in the video.
I also had to create a mask to make the bottom of the smoke fit the curvature of the cup.
At the very end of the clip, you can see a few frames of just the smoke (without the cup photo in background).
But the result is a mp4 file. If, for example, you want to make a seamless looping animated gif out of this, you’ll need other tools than just Shotcut.

That’s really good, @MusicalBox.
I just tried it following your instructions - oh dear, I think I overdid the steam. Best call the fire brigade

Yep, that is what I was thinking about. Thanks for the info all.
@jonray The hardest part is to find the right smoke for the job. I like yours best. I guess it only needs to be masked a bit on the left side of the cup.
Glad it could help you Johnny_Debt
