I am using Camtasia 8. Even though the audio, video, and callouts seem to be in sync on the timeline - there is a lag after the publish the video. I am using an mp4 video with .wav fiel audio. Can anybody help?
mp4's are still not quite the holy grail. Some times during transfer or the FFMPEG encoding the camera uses can make the audio a bit un-sync'd AFTER you render it in Cam. I know, sounds weird but I've run into it many times. Download Handbrake (free) and reconvert the original before you put it in Cam and then when you produce it using the profiles Cam supplies, the sync should be perfect. Not logical, but very fixable.
