Hi all... My camera creates video in the MPEG format. When I go to play and edit in videopad, video and sound skips. I saved as flv. movie then went to edit the file created, the audio was not available. The reason for saving first was to covert file format from the MPEG due to skipping problems. After saving I then opened again in video pad yet no audio available! I then separated the audio from video and attempted to save audio file as a mp3 and load with flv. video yet ..same problem...sound skips. Can anyone help?
