Can hear recorded audio in preview, but not available in edit mode

  • Updated 4 years ago
I'm using camtasia studio 7 on windows 7 (64 bit). I can record the screen with audio. When I preview the recording, I can hear the audio. When I click save and edit, then move into the editing screen, there is no audio. I can see that an avi file has been loaded to video 1. When I click the "play button," the timeline moves immediately to the end, and I do not see anything on the preview screen.

Hello Jerry. Can you be a little more specific on what you are recording and if you are seeing any line levels on the Audio 1 timeline? Would it be possible for you to upload a video or screenshot of what you are seeing? I just tried to do this same thing you explained and when I added the avi video to the timeline in Camtasia Studio 7 it played the video and audio back. I am just trying to figure out why you cannot hear your audio playback. Let us know and thanks for posting. Sorry for your problems but, I am sure we will get it figured out.

1. I originally recorded a powerpoint presentation from the add-in window of powerpoint. I experienced the same problem as I originally explained when I tried to view it in Camtasia Studio.

2. Then I began the process again by clicking the "record the screen" button in Camtasia Studio.

As I originally explained, there is absolutely no audio on the timeline. As soon as I finished the recording in paragraph 2 above, I could see the video and hear the audio. But when I clicked save and edit, then moved into Camtasia Studio, the video was loaded into the timeline. However, the audio was not. At that point, I could not preview the video in the upper right of the screen. When I clicked on the "play" arrow, it immediately jumped to the end of the timeline.

Are you using a Windows 7, 64-bit PC?

No Jerry I am sorry for that. I must have overlooked it and I have been pretty busy lately. Yes, I have Windows 7 64-bit PC. I do know that the PowerPoint 2010 64-bit does not work well with Camtasia Studio 7 as it does not support the 64-bit system yet. So is your PowerPoint 2010 63-bit or 34-bit? Just curious as to why the audio did not go with it. I recorded my PowerPoint through the Camtasia Studio PowerPoint 2010 32-bit version and it worked for me. Let me know and you might want to contact TechSmith Support on this and see what they have to bring to the plate for any ideas of why this is happening. I am sure we can get it figured out in time Jerry. Thanks for reminding me of your reply. Have a great day.

Thanks, Fred. I'm new to this, and I thought you were with TechSmith. I've looked around their website, and I don't see a way to contact their support people. They have a phone number for sales. Could it be that they don't want to talk about their problems? Can you tell me the best way to get to the techsmith support people?

I had the same problems with audio when I started the recording in powerpoint 2010 and when I started it from camstasia studio. My powerpoint 2010 lists windows 7 under system requirements, plus it also says windows server 2003 r2 with msxml 6.0, windows server 2008, or later 32- or 64-bit os.

Thanks again.

Hello Jerry,

Nope I am not a TechSmith Employee. Just a long time user like others here. I have provided the information for you below:

The link to TechSmith Support is below:

http://techsmith.custhelp.com/app/ans...

You will have to register for this as I do believe that the Log In information you use here will not work. Some employees post on this forum also which is great.

Please let us know what you find out Jerry. It might help other users who might have the same problem. I could always take a look through remote access with TeamViewer if you would like when I get time. Another good source for learning how to record a PowerPoint with the Camtasia Studio Add-In is the TechSmith Learning Center. The link to that is below:

http://www.techsmith.com/tutorial.html

Some good tutorials are in the list and they go by the product.

Hello Jerry,

Please see the support article below. I might be wrong, but it's my first guess. Are you using the PPT addin? You will still be able to record your PowerPoint presentation, but try using the normal recorder for this to work in the 64 bit version.

http://techsmith.custhelp.com/app/ans...

Here's another tip regarding PowerPoint recording. I personally prefer to avoid recording in full screen mode unless I am presenting to a live audience or have animations I need to show. Instead, I record in the editing view. This way I can still see my notes, and I don't usually need the full size of the PowerPoint for my viewers anyway.

This is a write up on Jing, but the process is virtually the same. http://blog.jingproject.com/2010/10/j...

Here's a link to our support team. I would definitely contact them if my first idea is no good. http://techsmith.custhelp.com/app/uti...

Sorry for the audio trouble, I hope this helps!

Thanks for your reply Mike and Fred. I'll contact support. As I explained above, I tried the powerpoint add-in recorder and the normal recorder with the same result.

I received a reply on 3/23/2012 from techsmith support.
Please see my response to Parker H. noted by parentheses at the end of each paragraph and attached gif file :

In a case like this, the first thing I would do is a simple restart of the computer, then launch Camtasia again to see if the issue persists. If there were a simple system resource issue, this should help give us a fresh start on the system. ****(no change)****

If the issue persists after restart, I would be curious about the recording file itself. With the file in your clip bin, can you please right-click it and go to Properties? In the new window that appears, there should be a section that shows you the width and height of the video - what are these numbers? In addition, what is the overall size of the camrec file? ****(Width 1005, Height 753. The size is 53.7 MB, but also did another 12 second video with only 1.2 MB and it has the same problem with no audio. See attached gif file to see all the numbers)*****

Finally, there is a known issue with Divx that I have seen cause this type of behavior before. If you go into your Control Panel -> Programs and Features, and look at your list of installed programs, do you see an entry in that list for Divx? If so, you may want to try uninstalling that program, rebooting the computer, and trying to view the file in Camtasia again. **** (Did not see Divx with installed programs.)****

I didn't mention my other problem which is also a major one. Camtasia Studio crashes quite often. I've had a computer repair shop work on the problem a couple
of times. The last time it worked for a few days, but now it freezes again. Does anyone know when techsmith will have a product that will work on a 64 bit pc with 8 GB of ram? I wish I had known before I purchased. Does anyone have a fix?

Jerry I am sorry to hear that you are still experiencing problems. I use a Dell Laptop running Windows 7 64-bit with 8GB of RAM and I have had no problems with Camtasia Studio 7. It does not work with the 64-Bit version of PowerPoint 2010 to well so I use the PowerPoint 2010 32-bit and it works fine then, I agree that it would be nice if the Camtasia PowerPoint 2010 Add-In would work with 64-Bit System it would be nice. I am not sure if any other users have had the same problems or not. This would be a great feature request if TechSmith has not got a solution.

As far as the Camtasia causing the computer to crash I have not experienced that with using the software. Did your computer repair shop give any specific reason of what was causing the crashes? Can you give more information on what happens when you say crashes? Does it just shutdown or a Blue Screen of Death, etc.? I would not think Camtasia Studio would be causing that problem. I repair Desktops and Laptops on the side and never ran into this issue with Camtasia causing the crashes. It was usually some Malware or Virus, Hardware Failure, etc. Let us know and thanks for posting back what they had to say. I hope we can get something figured out that works for you. Have a great day.

Fred, thanks for your help. When I wrote "crash" I should have been more specific. It freezes and stops working. I believe it is because the file that I was using was large. I may have to change the format to make a smaller file.

Regarding my problem of recording my screen and audio, being able to see a preview, but not being able to edit the camrec file, I have received a solution from TechSmith. Please see it below and then read my response with some suggestions.

TechSmith instructions:
My apologies Jerry, our system automatically closes a ticket after 7 days, and I had not received a reply email noting that your file had been sent! I was able to download the file to my computer, and I believe that there is some slight corruption to the .camrec file. When I bring the recording into Camtasia, I am able to play it properly and hear the audio, but the audio track has a flat line for the wave form. While this usually means there is no audio, in this case that waveform is simply incorrect. I then extracted the files from the .camrec, and brought in the raw .avi file that contains the video and audio information. This file also plays properly, while showing the proper wave form. I'm curious to see if you are able to get the same results.

With the .camrec file inside of Camtasia Studio, you'll want to right-click the file in your clip bin and choose "Extract camrec contents" http://screencast.com/t/g1a8mOCVnL1. This will bring up a window where you choose where to extract the files. I would recommend creating a new folder on your desktop, and extracting there for now. Once extracted, open a new project, click the Import Media button, and import the file called "capture-1_Screen_Stream.avi" and place it on your timeline. Does this file behave better for you?

My reply:
Thank you for your reply. Last night I was experimenting with "Extract camrec contents" function and was able to access a file that I created where I did not want any sound. Per your instructions today, I tried one of my files with sound; and when I imported and loaded the extracted file to the timeline, it worked correctly. Assuming this is a problem for most people, I think that you should change the options when I right click on a Camtasia recording file. "Add to timeline" should be removed from the small box that appears because when I clicked on "Add to timeline" I experienced these problems where there is no sound and the video cannot be previewed. Also, when I click on "Extract camrec contents," the "Browse for folder" window that appears should have instructions that... after I create the new file... I should start a new project, import that file, and add it to the timeline in order to edit it.

TechSmith's latest reply to me:
It should not be a common issue for your .camrec files to come in with the flat waveform, as this is usually a case of one-off corruption to a single recording file. If you are finding that all of your recordings have this same behavior, there could be some larger issue on the machine that we would need to investigate, but I am not aware of any cases where this has been consistent.

When right-clicking on a file, choosing the "Add to timeline" option allows you to add an entire .camrec file into a project. This is especially useful when you are using all of our recording channels - screen video, webcam, system audio and microphone audio. This behavior of adding to timeline should not inherently break the program or its interpretation of a file. Regarding my instructions to import the extracted files into a new project, this was merely to avoid any issues that could be due to a particular project. It is not necessarily a crucial step when an extraction takes place.

My reply to TechSmith:
Yes, all of my recordings have the same problem. I even recorded one that was less than 1 minute long that had the same problem. What are some possible problems with the machine?

Did you ever resolve this? I am having the exact same problem- all of a sudden all my old projects had flat waveforms, my new recordings had flat waveforms... I'm going crazy over here!
