I have a .mp4 video file with two audio tracks (microphone and system sound). When i paste the file in camtasia, camtasia dont show/reproduces the system sound audio track, camtasia only show and reproduces the microphone track. Have some solution for this?
To keep system sound synchronized with the video recording, the system audio is embedded into the same clip so only one shows on the timeline. The microphone audio displays as a separate track. You can edit the audio within the video clip (system audio) the same way you would if it were separate. Right-click video clip on timeline and select Edit audio. If you want to see them separately, you split them out by right-clicking and selecting Separate Audio and Video. If you do, system audio may be come un-synchronized with video when / if you make edits.
