Media Files Disappeared

  • Problem
  • Updated 3 months ago
I recorded a PowerPoint presentation with audio, edited it, and exported it to mp4 without issue. However, upon reviewing the material, I found that I had made a few mistakes both visually and orally. Instead of redoing the presentation, I decided to add images to cover the spots where I made a visual mistake and cut out/replace the audio of the sections where I made an oral mistake. I've done this before with other presentations without problems. This time, partway through the process, I was told I could not save the presentation. Attempting to save under a different file name did not succeed. Upon selecting "Revert last save" to solve the problem, all media recorded through Camtasia was gone. Attempting to update media shows folders that exist, but are empty.

I'm likely going to simply re-record the presentation, but I want to understand what went wrong so I don't do it again.

First off, what version of Camtasia are you using?  If you are not on the latest version, you may want to upgrade.

If you recently made this recording, then you likely still have the recording in your 'Movies/Camtasia 2018/Temporary Recordings' folder (or 'Movies/Camtasia 3/Temporary Recordings' if on Camtasia 3).  So if you open your project, you can right-click on the missing media in the media bin (not on the timeline), and choose 'Update Media'.  You can then browse to the Temporary Recordings folder and choose the file if it still exists (note that if you click the 'Options' button at the bottom left of the window, it will show you the name of the file that is missing).  If you find the file, then you should be all set and you can continue editing where you left off instead of starting over (I would save the project before beginning to edit it again). Note that the files in the Temporary Recordings folder are deleted after 30 days (you can set the duration to hang on the the recordings in the Camtasia Preferences), so if you are able to recover the file, I would copy it out of the Temporary Recordings folder and save it off as a safety backup in case your project looses it again (that shouldn't happen, but better to be safe than sorry).

Camtasia:Mac version 3.1.6 (103257), which is the current version, on a Macbook Pro running High Sierra 10.13.6

I was able to locate the recordings in the Temporary Recordings folder as you instructed and was able to restore them to the Camtasia project. Thank you! I am hoping there is some information as to how the situation occurred to begin with so as to avoid it happening again in the future.

Whenever I have a source file recording for manipulation into any other program I always will make a backup of the original prior to any manipulation.  Also you mentioned a MacBook pro, but are the files being read / written on the internal drive or an an external drive / sd card, etc.   I have noticed a few of my colleagues who used their laptops for these operations have problems with storing or reading directly into Camtasia (and other programs as well) but it seems to be larger files and seems more commonly at the last part of the process to write the media file that something goes sideways.  I do everything on a desktop and internal drive for importing/creating media, but I always make backup to work from.  After once or twice having to start from scratch with different programs a backup is now my go-to defense.

That's a very good point.  External drives, especially network drives, can at minimum have issues with delivering the data fast enough for smooth playback while editing. At worst, they become disconnected/reconnected and that can wreak havoc with a program.  For a video editor, it is always best to work with software and media on your internal drive and use your external drive for backup and storage of projects you are not currently working on.  In Camtasia Windows, there is even a warning if media in a project is being accessed from an external drive.
A second point that can save you some grief is to always work in the CMAC native format for projects (cmproj) and have the project set to save as stand-alone.  This packages all of your media and recordings into the same folder and makes the project transferable from one machine to another.  On the MAC, this kind of folder is called a bundle and is treated specially to show up as a single file to the user.  For a standalone project, if you move or delete a file on disk after it was imported into your project, it won't mess up your project because the file will have been safely linked or copied into your project bundle.

Finally, when starting a new project, it is best to name and save it right away (at minimum as soon as you first add media to it)  For a project that has not been saved, we have to do a lot of different, special work to keep it safe until it is saved and that state may not be as secure as the state when you are working in a saved project.

All files are being are created and used internally and the files that were missing were created in Camtasia as part of the bundle. I was able to transfer the files from the temporary recording folder into the appropriate folders in the bundle to restore the media and my edits.

As far as I know, with 3.1.6, that should not occur.  In 3.1.5 when fixing an issue it introduced the possibility that media could be removed from your project that was in use by the project if the file paths had certain characters in it that can be represented various ways. For example, a u with and umlaut can be represented as a single character, or as a U, a backspace and an umlaut. Because of the different encodings available we had to add a little extra logic to ensure the same encoding before comparing the file paths.  So only 3.1.5 had the issue and it was resolved in 3.1.6. It was the primary reason we released 3.1.6 - data loss is a very serious issue and we don't want it to ever occur in Camtasia.
