Audio cropping - awkward problem. Please help!

Hi!

Almost everybody knows how to split and cut audio using timeline tools in Camtasia...
Well...almost.

Problem: Whenever I try and split the audio track it splits into two pieces both starting in the beginning of the previous "non-splited" audio track. Almost as if it "copied" itself rather than dividing in the desired point.

This problem occurs only if i use external mp3 songs that do not belong originally to the program libreries - > i tried and splited into many fragments songs that were in the original music librieries such as Music - Electropulse /Full Song and it worked just fine.

I tried my best to describe this problem -  sorry for inconvenience.

Thanks!

Hi Jeremiasz,

Have you checked out this article yet? Sounds like it could potentially be a variable bitrate issue with your audio. Perhaps converting your MP3 files to a constant bitrate will help.

Kristen beat me to it! Variable bit rate audio files behave strangely in this regard. Constant bit rate files are linear and predictable. Conversion is fairly simple.

Jeremiasz,

Here is the workaround I am using for the same problem.


  1. Convert MP3s to files with the same bit rate (use Audacity, Handbrake, Adobe Media Encoder, etc.)

  2. Update media in your Camtasia project (right-click over clip > Update media > select new MP3)

  3. DO NOT SAVE OR EXPORT YOUR PROJECT YET.

  4. Export audio only (File > Produce special > Save audio as)

  5. Import new audio, sync with old audio, then delete/mute old audio

  6. Save project & Produce as needed.


Step 3 is VERY IMPORTANT--You cannot save your project as-is with the media updated. You will get errors and the project will reset on you, and you'll have to start fixing it all over again. You CAN, however, export a new audio clip that actually works, add that to your project, and then delete all the files giving you the problems. After you do that, then Camtasia will allow you to save and produce/export.
