Video Merge Technique

[wschumac]

I am trying to incorporate some green screen video on top of some video I shot at an earlier time.

I have placed the background video on track 1, while I have placed the foreground on track 2, I went to the Video Merge button in EFFECTS and performed a merge.

I am getting a lot of green screen rather than it being blended. I have done all I know to do. Can you help?
Is there something I am not doing?

I also listened to a video created by Adobe on this subject and I thought I knew the mechanics of it, but I am missing something.

The simplest of things are sometimes the hardest. I am back to doing videomerge. I used your TV180 flag to the video1 line and my green-screen video to video2-audio2 line and the audio is not working. I have done this few times to try different options and nothing.

I used it stand-alone and it works fine as does the other video and th speakers are on. Help please.

Thanks Walt

Have you referenced the articles Chuck linked you to above, Walt? You must be missing a step.

Can you describe the steps you're taking? It sounds to me like you're not correctly designating a key color and/or set the correct tolerance level.

Hi Steve:

Actually, I got the answer out of your book. I did not realize I had to go to properties ot finish the video merge off. I believed after I dropped the video1 and video2 objects, that it was done, but I then realized thru your color book, that was important. One question though. Can the green screen video be of any format?

Thanks

Walt

Yes -- and no. You'll get the best results with high-def video -- and, if you're working in standard resolution, MPEGs are not nearly as effective.

Basically, the higher the definition and the less the file is compressed, the better results you'll get. (Also, as I say in my books, good, quality, even lighting is VITAL!) Standard definition MPEGs are pretty highly compressed, and that can results in a less-than-clean edge to your key.
