I am editing and I want to add videos in .mp4 format and sometimes it does not have the sound but you play it in a video player if it has sound. Is it a camtasia problem or is it a video problem?

Try to re-encode your .mp4 file with vidcoder or handbrake to .mp4 file again. and re-import to camtasia again with no problem.

samarn is correct but I'm wondering if the MP4 file had been renamed.  I used to have to change the suffix of files to get them to play in some players or Camtasia.  E.g.  3gp to mov;  mov to mp4, etc.

One way to know if it is really an MP4 file is to look at the header.  One created by CS8 contains information such as "ftypmp42"; "isommp42" at the start and a bit later it contains "Mainconcept MP4 Video Media Handler".

It's Camtasia 9 that went a step BACKWARDS.  This always worked in V8, now in V9 it doesn't - and it sucks.

It might be that the Camtasia sound is off.

Right-Click on the sound icon in the taskbar and then Sound Mixer and make sure Camtasia is turned on.

Here it is off indicated by the red circle . Click on the speaker to turn it on

I've noticed that all MP4 videos are not supported by Camtasia, because they've been encoded with some unsupported codec. One "simple" way to fix that is to upload the incompatible video to Youtube as a private video, and let Youtube to do the video conversion. When the conversion is ready, you can download the video from Youtube and after that it works beautifully in the Camtasia too.

Just tried this method and I still don't have audio. Again, the new file plays in QuickTime with audio. Using Camtasia 8.

I use the freemake video converter program (make sure when you install it you don't install all the bloatware, malware just choose custom install that way you don't get all that).  It has a convert mp4 video to mp3 feature that use to get perfectly timed mp3 that I import to camtasia and put it just below the video with no sound.

I just wish there was a fix for this to save us some time this is obviosly a bug on codecs either from the compression program or on camtasia's side decompressor whoever's fault it is I don't really care I would love for someone to come up with a patch for this

Why bother paying for Camtasia? 

I might challenge you to try recording your screen, editing, animating, and everything else Camtasia does using only YouTube. I'll be quite happy to eat my hat if you can make YouTube do it. ;)

Cheers... Rick :)

The first choice, you need to make a video again. For the second option, you can use HD Video converter factory pro to fix the no sound issue and then import this video into camtasia.

I'm having the same problem on the MAC version , it is really frustrating and I don't understand the logic behind the backwards step
