Audio and image stuttering/halting/jumping (whatever you want to call it) when trying to edit videos in Camtasia 9.

I have audio and image stuttering/halting/jumping (whatever you want to call it) when trying to edit videos in Camtasia 9. These are vids recorded in C9 by my co-workers, sent to me for editing. I re-format them to an Mp4 to make them even workable, as the .trec files are so distorted I cant even begin to edit them. I am trying to work within the perimeters of the company computers, so if I need to update things, that could be the case. But so far with all the searching through forums, I have not come up with much help for C9 issues, much less this one. Any insight would be helpful, as losing my mind in the next item I feel like I will be checking off my "to-do" list:)

since these are media clips recorded with Camtasia Recorder [CS9 Recorder?], the symptoms you describe suggest that you are using an inadequate PC system 

but when you say you "reformatted" to MP4, how did you do that?

CS9 generally has excellent performance during editing [I use an i5 laptop with 8 GB RAM and a SSD system disk]

also, you should be able to work directly with the .trec files without issues

Hi Moira, when you say 'vids are being sent for editing'  are you doing this by exporting and importing a zipped project? If not, try this route to see if it helps. You can do this from the Help menu.
Cheers,

waited until I had a video to edit.  The edits are minimal.on this 45 minute MP4 video (1.7 GB) file.

  • Reduced what little noise existed
  • replaced a 3 minute section of the video with the mp4 file that was presented in Church.  About 4 minutes into the video.
  • applied a 7 second wmv file (splash page) at the beginning.
  • So far, no stutter.
  • Split the splash at 4, 5 & 6 seconds reducing the transparency to 75%, 50%, and 25%
  • Stutter for about 4 seconds beginning about 4 seconds into the video.This is normal.  However, for this test all files, including the project file, are on the SSD drive rather than the SATA. 

Saved the project.  Closed CS8.  Reloaded the project.  Stutter gone.  This "trick" doesn't always work.

Computer stats:

  • Windows 10 Professional (x64)
  • ASUS ROG.G751JT
  • 2.50 gigahertz Intel Core i7


I was really hoping the SSD drive would help!

I am having this issue as well. I record audio in audacity and convert to MP3. I import the MP3 into Camtasia 9. During editing there is one word that stutters. When I produce the Video the same thing happens in the MP4. I have expanded the audio in the editor and the stutter will go away but it still appears in the final MP4.

save Audacity audio as a WAV; MP3s do not work well in CS9

thanks for the feedback, but I did find that WAV was supposed to be the solution, but when I try to import WAV files I get a message that this file format is not supported.

after I wrote the comment above, I thought I should check the import of WAV files, as I have had several problems with Windows 10 and Camtasia 8.6 and 9.0. It appears I can import WAV files now. So I will try that.

Hi Leonard;

Just an aside I wanted to pop in here and mention that  WAV files that are 16-bit, 44.1 kHz work the best in Camtasia. It is possible to get an "Unsupported file/format" error if you try importing, say, a 32-bit WAV file.

That is what I was doing, thanks for the heads up
