I need to create such effects in my vidoes:
* Insert clips from different videos together
* When a video is running, mix a video im a small clip on top right corner.. (just like a news channel)
* slow down video, and move text around in normal speed when video is slowed down
* Change colors of scenes, like make it grayscale, or green or any other color
* Mix scenes from two separate videos using transparency (like greenscreen.. a person is standing and moving normally in front of greenscreen and I replace the green background with any other video clip that I have)
* Create cloning scenes (like two clips of the same person on the same scene.. clones)
Which software would help me create such videos? I heard Adobe Premier is good enough but Im not sure about that greenscreen and cloning scenes.
Also please give me some links of tutorials on making those greenscreens and clonings.
