hey all heres a question im curious if someone can answer i am experimenting with a demo of afterdark 6 heres what i would like to do not sure if its possible

shoot video say of me running down a street then
shoot video say of a forest path and a first person view running down it

then key it and put the video of me running key out street and drop it into the video of the forest path so its 2 videos combines into 1 of a man running thru the forest....

can that be done AE6 didnt quite seem to do it or give much info and as im a beginner i cant afford blue/green screen

also where can i get if possible time lapse video again without paying of nite and day passing fast to show passage of time
i would love stock footage without having to pay as im a beginner bnot sure if its possible tho.....

Hello Nicholas,
I assume that you're referencing Adobe's After Effects, not "After Dark", eh?

AE can certainly facilitate chromakey composites, which is what I gather you want to do. Honestly, I read your post several times but still cannot quite decode exactly what you envision.

In brief, however, you would need to shoot one subject in front of a chromakey background in order to make the composite work. You may be able to create such a backdrop relatively inexpensively with chroma paint and some inexpensive background material.

As an example of how you might be able to accomplish something like what I think you want to do... Perhaps you could shoot footage of yourself running on a treadmill with the chroma background behind you. Then shoot footage of a walk through a forest. Use AE to drop-out the chroma backdrop and substitute the forest footage.

It will take quite a bit of practice but I think you'll find such a project fun and instructive.

Good luck.

Nicholas, I find it very difficult to read your posts. Please add punctuation and use capitals. It really makes a difference. If you're going to take the time to type it all you will maximize your chances of getting an answer if people can figure out what your saying with a minimum of effort.

Just a suggestion.
