Description stiven guillaume 2016-07-24 23:17:06 UTC

Hello,
I'm using Kdenlive to make sciences videos, and i think an effect to generate drop shadow should be a great innovation.
For the moment, i modifiy all my picture on gimp. Long, long and long job :)
Thank you very much.

Reproducible: Couldn't Reproduce

Stiven, maybe your effect can be reproduced in MLT/Kdenlive using the existing effects and transitions. What is your source footage? What do you do currently in Gimp?

Comment 2 stiven guillaume 2016-07-27 16:00:45 UTC

I didn't find in kdenlive's effects. 
On gimp, i go on "filters --> shadow and light --> drop shadow"
(or something like that, i use it in french :/

The only way i found in kdenlive is to add a transition between the picture and another picture in png where i got only shadow. 

So, i need 8 tracks to "shadow" 4 pics

i make vidéos like you can see on my website http://www.etcomment.fr

Ah, now I see, you want a drop shadow around your frame in a way similar to what Gimp does? There's help doing this using the built-in effect and transitions in Kdenlive.

The bug tracker is not intended for this kind of discussion and help. If you please, can we move this discussion to our Google group? This way, others can learn too. Also, I need some more information; so see you over here: https://plus.google.com/u/0/communities/114460978880033344765

Is it correct that you need the drop shadow only for picture in picture clips? Then this should be easily doable using a title clip containing the drop shadow, with this clip simply below your picture-in-picture clip.

Which Kdenlive version are you working with?

By the way, the way you did it using two tracks for each clip+shadow is the right way to go!

Haaaa, ok. So you can close it :)
Thanx for your help :)

I can't, so please be so kind as to close this report.

Doing drop shdows as an effect would have to be done at the MLT or frei0r level, so with different upstream projects. Such an effect would need several parameters, such zoom and position, as well as the shadow parameters. Thr zoom, position, and rotation would need to be keyframable (animatable). A lot of work for a dedicated effect...

Ok no problems. 
I'll try if i got the level to dev it :)
