I can overlay music and on screen text.
I can join two videos together, or split a video into parts.
I can also crop part of your video screen as part of the edits included in this gig. For example, a stage being filmed but there was a wall in the way of the camera on one side. I can crop the video to remove the wall, and the stage is now full screen.
I can create the output files in any of the common formats such as AVI, MPEG, MP4. WMV etc.
