edited Camtasia 9 recording results in audio issues when produced to mp4

  • Updated 6 months ago
Using Camtasia 9 to record screen activity.  Using both Camtasia 9 and Audacity 2.0.6 to record audio separately.  Import both into a project, make edits to screen recording, add annotations, cuts, splits, extends, etc.  Everything looks and sounds great in Camtasia project, but when I produce to an MP4, the result is a video with audio skips, bumps, talkovers, etc.  I've tried every corrective action I can find within TechSmith and in blogs and editing sites.  This has only occurred since upgrading to Camtasia 9 (never happened in version 8).  Can anyone provide a solution?

If I am reading this correctly you're saying you have two audio tracks that are delivering the exact same content, is that right? If this is the case I'd suggest getting rid of one. Another suggestion would be to make sure that when you're bringing in your Audacity file make sure you're bringing in an mp3 not a wav. I've had several issues with wav files from Audacity in Camtasia 9, and I think it's a codec issue, but the answer for me has been to use mp3.

Sorry, but no you are not reading correctly.  I don't have 2 audio tracks. I have only 1 track, producing video 2 different ways.  One as MP4 Only (1080), and the other with the SmartPlayer.  The MP4 only causes audio burps, skips, overtalks, etc.  (However, I'm also now experiencing the same with the SmartPlayer if there are a lot of edits to the screen action timeline.

Also I do export the audacity as an mp3.

Thanks for interest.  (I'm bugging out for a while...going on leave, so no offense meant by non-reply for a while.)

Ciao.

This is happening to me as well - audio and timing are perfect in Camtasia, but the voiceover cuts out in the exported MP4. (Tried both 2080 and 720). The export is not useable.

Hi Erin;

Does this happen with all projects or just this one? What format is your audio file? Camtasia works best with 16-bit WAV files at 44.1 kHz.

Hi Robert. Thanks for the quick reply. We've been creating videos for quite some time either by recording voice directly in Camtasia or importing mp3 audio. We've never experienced this issue  until yesterday.  I installed the update yesterday - could this be related? 

I'll be really disappointed if I have to re-import and re-edit the audio. I spent quite a bit of time getting it right in Camtasia. I was  shocked to hear that the export did not play back the same way as it did in the actual program. 

Also - is there a resource you can point me to regarding the 16-bit WAV/44.1 kHz? Thanks in advance. 

-Erin

Hi Erin!

It is entirely possible that there was a change in the back-end somewhere; a Windows update, a driver update, or even a software update. I have yet to see any other reports of syncing issues with regard to the update to 9.1.2 so it could be something local to your machine.

You may not need to re-edit the audio; if you use a tool such as Audacity to create a 16-bit WAV file from the MP3 file that you used, you may be able to right-click on the MP3 file in the Clip Bin and choose "Update Media." A window should pop up asking if you'd like to apply the edits, thus mitigating the need to re-edit.

Also, does this now happen on all projects, or just this one in particular? If you open an old project that you know was in-sync, does it produce out-of-sync?

I have this same problem with audio narration recorded in Camtasia 9.  Its frustrating.

Was this ever addressed? I am experiencing it now.  Imported audio as mp3 and wav.  What is strange is I can put the play head at the beginning of the timeline and play and it will skip words or portions of a sentence.  Stop the play head and return to the beginning and it will play complete.  I also experience what others have reported above in published MP4 files.

I have the same problem with Audio repeating 5-10 seconds sections in the export file. File has been done using 3 different format options.

Hi Tonyr;

Are you using imported media files or are you using Camtasia Recorder files with this? Does it happen with all projects or just one in particular?

Hi Robert,
We are using MP3 files recorded with Audacity then imported into the project. We have re done this project 3 times to confirm issue. The repeat cannot be heard in the project environment only in the final export file. This export has been done both as a local file and also a direct to Vimeo file.
Out previous projects are done before the update. I am doing another project this week so will confirm if repeat issue occurs.

this is happening to me too, with an mp3 file. It outputs with a brief distortion with either the mp4 only or with the player. I had to convert the file to .wav, another step. Hopefully Camtasia can put out an update to fix. I am using windows 10 pro,

Lauren, I think you may have found the workaround for Windows until TechSmith gets this major flaw corrected (I hear that .wav files are proprietary to Windows).  The main purpose of using Camtasia is for the editing features it offers, but if that functionality is rendered useless then who needs it?  I've thoroughly enjoyed using Camtasia until version 9, which has WAY too many issues.

I have the same problem trying to import mp3 files into Camtasia 9 from Amazon Polly. I am working with Robert at TechSmith support to try to find a resolution.  It worked fine with Camtasia 8.  I can't export a WAV file with Amazon Polly. The only workaround is to import the Amazon Polly mp3 files to Audacity, then convert to WAV and import to Camtasia 9.  This causes too much extra work for us.

I'm going back to Camtasia 8 so I can import Amazon Polly .mp3 files. Robert in Support said he entered a defect about not being able to import them with Camtasia 8 or 2018.

I'm having an issue with this in Camtasia 2018. It's causing some serious headaches. For each video I produce, I get an audio blip right around the 1 minute mark. The only workaround is then taking the published mp4 and putting it into a new camtasia file to see if I can edit out the little audio repeat. If I can't get this to work properly, I'm going to have to find something else to develop these in. Really having too many issues in 2018 version to start another project in Camtasia again.

could you provide an example of an MP4 that has the issue; host on screencast.com?

also, please provide a screenshot of the project loaded in the editor, there the playhead is located at the area where the blip occurs, and with the timeline zoomed in at that point?

It's a real shame that this problem has still not been fixed in Camtasia 2019.

Here's a video that contains a dropout around 2:00:

https://youtu.be/RH0drcivWdk

When I replaced the MP3 with a WAV version the rendered file was correct.

Converting the MP3 to WAV may be a workaround but it's not the solution. The solution is that the developers take a look at this and fix it.
Camtasia works best with 16-bit WAV files at 44.1 kHz.
Camtasia should work best with any supported audio file. MP3 is not exotic at all. It's a real show stopper to have to check each rendered file before using it because audio mixdown is not reliable.

lukas I responded to your other post on this issue and I will try and do some experimenting again when I get some time to see if I get the same results. I would like to know more about your way of setting up and recording when using Studio One Software for your audio to see if I can try to replicate it myself. Thanks for sharing any information and posting. Have a great day/night.

I just recently finished my first project, new install of Camtasia 2019.  I added a SFX of a mouse click.  It looks and sounds great when playing the project in Camtasia.  Upon outputting as a  "MP4 only (up to 1080p)" then that sound effect is not there.  I have a keyboard typing SFX as well and that one works.  I have tried converting the file to the recommended 16-bit WAV at 44.1 kHz, converted to stereo, converted to match the keyboard SFX, etc.  Nothing works.  Apparently we still have an issue.  Everything else works, just not that file.  I am converting it with Adobe Audition.  I guess I will try a different format, like .mp3 and see if that works.

Just tried an .mp3 and it didn't work.  It is weird, both SFX are on the same track, one works, the other doesn't.  I then tried a new project with those two SFX with just a basic background and output and they all output fine.  So it looks like it can do the SFX file fine it just won't do it with the entire big project I have.  Not sure why.

Alway export audio from Audacity or other editors as .WAV files. MP3 was never intended to be an editing format and the underlying OS decoding stack we use struggles to return valid info about it. We're looking at ways to fix this, but it's not a simple solution. Apologies for the inconvenience.
