I have had a person that continues to ask extra payments for two videos. I am refused to pay him, then I have a video non completed. a) In a video where there is a written, you should create the video from zero eliminating the written "unpaid". b) In a video where there is a logo, you should create the video from zero eliminating the logo. c) In more there is third video in flash, it must be converted in m4v for youtube My budget is about 150 $, I don't pay in advance with escrow. I pay 50 $ for every point.
