I am not sure if it can be done, I am still learning how the Composite lab works. What I am trying to do is to change a background full of power lins and telephone poles with a bule sky or sunset.

I don't have a problem with still photos, but when it comes to Digital Video clips, I am not fully understanding the concept on how to do this?

If some one can give me some guidince

Thanks alot

Hello. Personally, I would place the replacement sky video on the row below the sky video you want to replace. I would then draw a garbage matte around the area of the sky that I wanted to remove. This will remove the selected area and allow the video below (the new sky) to show through.
Hope this helps.

Hi,

But this only works if the Camera doens't move. If the Camera moves the background will stay where it is. You need to track the footage to keep the BG in place. But no Fxhome Software supports this feature yet. (Still, I hope it will come soon)

True, but there's no harm in manually altering the garbage matte and tweening a few frames. It's a lot of work, but can bring good results.
But, yes, please let's see some kind of motion tracking soon!!!!
