what is the video editing process of taking objects out of one video and mixing them with another

[concernedcomputeruser]

I'm working on a website and I have a few ideas and I want to take certain people from one video and merge them with another. I am using this as my intro video for the website and dvd. What video editing software does this?

Generally, that would be done with a green screen.
Shoot the video, then just blot out the 'green'. Overlay that on the other video.

Taking moving parts out of one video otherwise is a frame by frame issue.

Agreed.
There MAY be software that can do this but I'm not aware of it.

For pictures I use the "Lasso" tool.

I tried to google "video lasso" and nothing showed up. Probably nearly impossible since the background would change so merging would be unlikely without gaps.

That's why they use a blue or greenscreen so they can merge together as the screen is a common color so it's easy to extract only the video objects that are a different color, ignore the screen and simply place the video object you want kept over any other video.

It can be done but as has been mentioned it is a frame by frame process and can be quite time consuming depending on the amount of movement and the background. That said, you can use the rotobrush tool in Adobe After Effects to achieve the desired result.
