Hi,
I'm an animator/vfx/illustrator in London. I have been doing compositing and VFX work for the last year at my current work.
I can do this in about an hour or so, depending on the quality of the scene, and the background you need to have the subject placed into. Obviously, if the subject is significantly lighter than the background, there will have to be some colour correction to be done.
Either way, this shouldn't take too long.
Do you have a screenshot, or single frame from the footage and the background to be used that I can show what it should look like as a trial of some sort?
Many thanks. Look forward to speaking with you further.
Ken
