I need a video editing tool with following functionalities.
1. Should support all available format of video.
2. Should be compatible with all codec.
3. Should capture image in a regular interval to form a series of thumbnails.
4. Thumbnails should be merged to form a large JPEG image.
5. Split and join some selective part of the video.
6. Caption or eraser for some area of the screen. This area (small rectangle or eclipse) should be movable in between the frames.
7. Quality or frame rate etc should be impacted after editing.
