Audio Editing Problems in Camtasia Studio 8

I hope this isn't redundant. I spent a bit of time perusing existing topics and didn't find a match.
I'm using Camtasia 8.0.2.918 on Win7 with8GB ram.
I'm having a problem with editing audio that I had with the first release of Camtasia 8.

It might make more sense with a for example.

I have audio where I say "It's not going to rain today."

I want to edit out the "not", so I select that portion of the audio and cut it (which I can no longer do by hitting the delete key? :( ).

I back up my starting point to a little before where i start that sentence and listen and it sounds great. "It's going to rain today."

Again, I listen and it's fine.

A third time it suddenly becomes "Itgoing to rain today"

I have tried starting about 10 seconds, or longer before the sentence and sometimes I hear:

"its going to"

other times

"itgoing to..." or "igoing to..."

This makes me nervous because I have no clue what I'll get when I render my final video.

When I had this problem wtih 8.0.0, I sent tech support some files to see if they could reproduce the problem. I hadn't heard back so went back to Camtasia 7.

I'm now working on another video so thought I would try again, but I'm still having this problem. It's not happening on EVERY edit, but it's happening often enough that it's disturbing. It's also hard to be productive when I have to make an edit and then listen to it 10 or 20 times to make sure it's consistently what I had intended.

Is anyone else experiencing this? Is tehre something I might be doing wrong or set up wrong on my computer? I've been using camtasia for many years and have always done detailed audio editing like this but have never experienced this problem until C8.

Thanks for any help/confirmation/feedback.

adding more...sometimes a entire word at the END of the "left" side of the cut just disappears after a while

I think I've licked this problem. I had been recording at 15 frames per second. I don't know why. But recording at 30 frames per second then going into Studio to edit, I have much better control of the fine grained audio editing. Not only is it back to what I'm used to...it seems even better and smoother than Camtasia Studio 7. I think now I'm going to get to enjoy the many great improvements to C8 that I was about to give up because of this problem.

I am also having this problem and it is extremely frustrating - to the point that I regret uprgrading from Camtasia 7. The issue is exactly as Julie describes it in her original post. Unfortunately, her solution is not working for me. It is nearly impossible to work on Camtasia 8 because - as said in the original post - "I have no clue what I get when I render my final video." I'm upset because Camtasia 7 was such a reliable, user-friendly product that I upgraded to 8 as soon as it was available and I got burned badly. This audio issue does not seem to be getting much attention (at least I cannot find any solutions from Techsmith) even though it makes the product nearly impossible to work with. Editing times take longer and you just have to pray that the 1 in 5 times the audio playback doesn't have holes is going to be the result you end up with. I make training videos as part of my job and this issue is a major obstacle. I'm trying to figure out how to explain to my employers that the upgrade they just paid for broke the software. I am researching Techsmith's competitors looking for a product that is more reliable. This issue needs to be at the top of this list - this isn't just that a button has been removed or that the interface is not familiar - the audio editing issue means that the PROGRAM DOESN'T WORK! How are you supposed to edit a video when the audio playback is different every time?

Rush, I made another discovery after this started happening again. I found by accident that if I move the left chunk of audio to a different track, that the transition is is smooth and as far as I hae seen (well, heard) consistent.i need to blog this. I would loe to know if it helps you too. I'm with you on all of your points of frustration.

I've noticed this issue as well. Most of the audio edits I do are post production work for training videos and such. What happens is when I click on a spot on the audio timeline basically to rewind and listen back to the audio to double check my edits, the audio playback will have staggered and the edit will be heard (but not seen) in the wrong place. The only way I was able to manage the issue was to click the rewind to beginning button, and as you can imagine, makes editing much more time consuming. My impression is it's some issue with the playback function. Sliding the audio tracks to the far left, or 0.0 seconds mark on the track seems to make the issue manageable

You might be better exporting the audio to a decent editor (audition etc) which isn't limited by frames - audio needs more precise alignment that only 15 samples a second. Once you've edited the sound, import it back into camtasia.

Audition will see a Camtasia file? Or do you have to convert it? And if so, what file type works best to separated the audio from the video?

export the track as a wav file. from memory you have to split it first from the video

I had a similar issue when splitting an imported mp3 audio file in Camtasia. Playback would repeat after a split and the timing of audio did not match that shown on the timeline as it played back.


This was resolved by avoiding mp3 altogether and sticking to WAV files. I suspect Camtasia has an issue with how it splits/times compressed audio files.


While there is a workaround, mp3 is provided as an import option so this is definitely a bug.

I realize this is an old thread, so this is more for new people finding this thread via a Google search...

With Camtasia Studio 8, MP3 audio that was encoded as Variable Bitrate can cause issues like those described in this thread.  The problem with VBR MP3 files is that there's no index which describes where the "frames" of audio are in the file.  This affects seeking, cuts, and pause/resume.  Basically the only thing that works with these files is playing or producing the whole file with no cuts and no pausing.

If you have such a file, and you wish to use it, the workaround is to produce just the audio as a constant bitrate MP3 file, or export the audio to uncompressed WAV at 44.1 kHz, 16-bit, Stereo.  When doing this, do not make any cuts.  Use that file (the CBR MP3 or WAV file) instead of the VBR MP3 file in your project in Camtasia Studio 8 or earlier.

With Camtasia 9, we've improved our support for VBR MP3 files such that these workarounds are no longer required.

I have this problem in 8 and 9.  I will try the wav method next time to see if it behaves better...  
The hassle is I get the VO tracks from my smartphone and if recorded in wav they cant be emailed because of uncompressed size issues.

I did a test.  Played Mp3 edit and it did the problem noted by the thread author in first post.  Then I exported the audio as M4A format and put it in the timeline instead.  It acted fine with no glitches.  I also recorded a new M4A and edited it very tight and it would not exibit the problem in the timeline.  I can use that format then.  I also found my smartphone app can share to google drive so a wav should work now for me without file size limits of emailing...  Hope this helps others.l
