1. First, I'm prompted to find my Camrec file. NO biggie - i just point to it.
2. Then, I get multiple prompts stating "Invalid or unsupported audio stream."
3. After clicking ok 15 times, my project displays but all the voiceover audios are blank.
4. If I play the file, it crashes when the timeline hits the blank audio segments.
The Camtasia file worked before i renamed the folders. I don't remember what the old folder names / structures were, or else I'd just change it back.
Do I have to create the video again? Not a big deal, but it will just take another 2 hours to mix and edit everything again.
I wish Camtasia wasn't so sensitive to folder and file location changes.
I also added them to a new Camtasia file.
I just tried to open the original Camtasia file again, and now it says the whole file is not valid.
I'll just scratch this one up to a corrupt file redo it. I can recreate this 60 sec video in 2.5 hours anyway. If it occurs again, i'll start creating backup files and exporting the file.
I have just LOST all my work (the latest at the moment). Incredibly frustrated - this is beyond words.
if you know how to use it, you can accomplish some amazing screencasting tasks, and create some stunning video productions
Sometimes, out of the blue, I get the error message "invalid or unsupported audio stream". This is when I am adding a clip to a video that I am editing. It doesn't happen all of the time. Does anyone know why this happens? I would love to understand it ads it creates many problems.
Thanks for your reply. I am on the latest version of Camtasia Studio8. This happens when I am editing a camproj file and click " record screen" to add another clip to incorporate into the video. I am only using Camtasia audio from the recording screen. This usually works really well for me. But sometimes I get the above mentioned error message. I can get through it but it takes many successive clicks to save it after the edits. I just can't figure out why this happens or how to avoid it. It usually happens after I have already made many edits to the video. Is that the issue?
Is there any feedback from technical support on how to resolve this as it is mightly fustrating and the loss of time is painful . I have logged my issue with them but have had no response.
The main reason of this error is the most number of clips used in one project. I wanna to tell you my own experience here. I created a project in Camtasia Studio 8 & save file in my computer/My documents. There was 10 video files in my project & I also splited 100s of clip from that 10 Video files & created 11 groups of video clips. Whenever I created 10 groups the file was opening fine in camtesia studio & after that I created 11th group & add more video files & save and then when I open the same file it shows me error "Invalid or Unsupported audio Stream"
After that I researched A lot & got the solution of it
The solution of this error is that you have to move your project Source Video files to another location in your hard disk.(I suggest you to move them in single folder which will help you when you relocate them).when you will move your source Video files to another location "For Example (Move your file from Local Disk D to Local Disk E Or From My Document/Camtasia to Desktop" & after that open your Project file in Camtasia it will ask you that your files has been deleted or moved from source location Do you wanna to relocate them? Here Just Click No ,No ,No ,No ( Clicking on No Options Depends on the Quantity of Your Source Video File) Now your project will open in blank videos files & blank clips on timeline.Here you all have to do is that just relocate your Video Source Files. I means give a new source to Camtasia where you moved your Videos files.. I hope You understood...

Well, I know how to move this Source video files but I don't know how to relocate them AFTER I clicked no.. Cuz then nothing appears on my timeline or it stay's blank. I don't know how to fix it but it always appears when I put long videos and edit them alot (many cuts, splits etc.) Is that the problem? I tried to reduce those splits and on some points totally remove them. just pasted the whole unedited video and still fails at the some point... (sometimes at 2.8%, sometimes at 8.2% etc.) And after some unsuccessful rendering tries it says that its invalid or unsupported audio stream. I think the simplest solution to this is to take the camtasia screen recorder and just record the preview and then edit some fps-drops out.. but that's not what I payed for Editing!!!
