30 Minute Camtasia 3 Mac Video Taking 8 hours and Counting to Save MP4 (Please Help)!

  • Updated 3 months ago
I've created several videos that are 15-45 minutes in length with no problem. This time, I created a 30 minute video, and this is my second time trying to save it to my computer (Mac) as a MP4 file. The first try, it took over 18 hours and it was only 56% complete. This time, I'm 8 hours in and it's getting stuck at 56% again. I've cleared out the com.techsmith.Camtasia.plist  from my library and it's still getting hung up. I'm using Camtasia 3. I'm thinking about ditching Camtasia altogether because I've missed a deadline because of the delay in saving this file. Any help or advice?

Camtasia 3, although it was replaced 2 years ago by Camtasia 2018 and now Camtasia 2019, successfully produced millions of videos. You say you have used it successfully yourself. This means the problem is local to your computer or project file. You should probably follow these steps in order:  
  1. Consider downloading a free 30-day trial of Camtasia 2019 to test on your current project file. It can coexist with your Camtasia 3 and might quickly solve your problem.
  2. Have you upgraded some component of your computer, like OSX? This might force an upgrade to a newer Camtasia.
  3. Did you try to shut down and restart your computer? 
  4. Are other memory hogs running on the computer? Word, Excel, PowerPoint, Premiere, Photoshop, AfterEffects and browsers are all hogs. Quit them, shut down and restart.
  5. Do you have several GB of free disk space? 
  6. Is there something weird in the middle third (around 59%) of your timeline? This can be time-consuming to track down, but we have seen cases where corrupted or incompatible media on the timeline caused problems.
Please tell us if any of these cause a change in what you see happening.

I've upgraded to the latest OS and have shut down/restarted my computer. I've got plenty of GB. I'll check that 56% point to see. All of my other programs were closed, only camtasia open. :(

Keep working the list: Did you download the free trial of Camtasia 2019? And the fastest way to check suspect clips on the timeline is just to replace them with another clip and produce the video. You could also try producing the first third, second third and last third of the timeline to help ID a bad clip.

Or just contact Techsmith support.

First thing I would try is to create a new user on your mac, and see if it works under that user account.

Quite a few preferences and libraries are stored in user folders on mac OS and I've seen this solve all kinds of issues for others before.

Your 56% issue does seem like you've either run out of a resource like Ram, or Disk, or you have an issue with content at that point in the video.

Since it's breaking during an encoding, the encoder might be encountering something it doesn't understand, this would often be a non-standard resolution video, or non-standard audio.

Pulling stuff off the timeline around the 56% mark is probably easiest but you could also try rendering without audio, and also do an audio only render to see if both or only one fails, which might help narrow down which items is causing a problem.

That also reminds me of one thing I ran into on Camtasia mac once - I don't remember what encoder I was using but I had a nonstandard (ie not 1920x1080) resolution and it crashed on render, changing the output resolution to 1920x1080 fixed the issue.

Sorry, I've not used a mac in a while, this ALSO reminds me that the mac version of Camtasia had multiple encoder options, and it's been too long so I can't give you steeps but when you go to 'share' I thought there was a normal and an advanced and one of the advanced ones gave multiple encoder options - so you have a few alternatives you can try if one of them is crashing.

Thank you all for the replies. Support was able to get the file converted for me. I wasn't able to determine the exact problem. One thing I did different on this video than other videos was using an iPhone X for the video instead of my logitech cam. Support mentioned that w/the iPhone file being a .mov file import instead of MP4, then that may have been the prob. I didn't see anything strange around the 56% mark of the video. Still a mystery. Hopefully my next video will be more smooth!

Just an anecdote here.

I'm using the PC version and I've been working the last few weeks with a gentleman where I'm preparing videos for him and using Camtasia. Several of his videos were recorded on an iPhone and came to me in a MOV container. They did go into Camtasia okay, but it did seem to cause grief when editing until I converted them to MP4 using Camtasia. Then things settled and editing became a whole lot smoother.

Cheers... Rick :)
