Camtasia 2.7.1 on Mac - Huge file size after export

  • 5
  • Problem
  • Updated 6 months ago
I'm a relatively novice user of Camtasia on Mac (Version 2.71.). After performing simple edits on a 25MB .mov file (i.e. removing pauses in the audio) and then exporting to mp4 using the default export setting,  the resulting mp4 file is over 105 MB. The canvas  size is 1024x768 and the movie clip is scaled to fit.  I've tried multiple times to export, trying to reduce the file size by reducing the quality, using the Advanced export settings, but the exported mp4 file ended up being either being of unacceptable clarity or with file sizes that neared 200MB. 

I've seen multiple posts that complain of huge file sizes and the lengthy export process, but I didn't find any response that provides guidance about the actions I should take.

Thanks for any advice you can offer.

I used Camtasia Studio (PC) up to just 6 months ago and the file sizes after export was MUCH smaller (comparable projects) than the case for Camtasia for Mac. This is a huge drawback, 10-15 min recording 1280 pixels etc... 200-300MB file size. On a PC project/export the same file size is about 50-70 MB. I really hope Techsmith is looking into this - MACusers are increasing in numbers!

Any comments from Tech Smith here?  I'm using Camtasia for Mac and I'm having the same problem:  import a 100MB .MOV file, trim a few seconds off of each end, then export as mp4, and the result is a 1000MB file!  10 times growth form trimming 8 seconds off, what's going wrong here, I can't even use video files that large.

Any response from Tech Smith would be awesome, or other users that have a solution.

I have "resolved" my issue of unacceptably large file sizes and little control by recording my videos on my Mac, but editing and producing them on my old PC using Camtasia Studio.  Before  moving to this solution, I tried reverting to the older version of Camtasia Mac that had more controls (2.8.3? It has been a while, so I don't remember),  but my file sizes were still 5x what I could achieve with Camtasia Studio on my PC.  Techsmith confirmed that either using Camtasia Studio or running my videos through a 3rd party program were the only two options available. 

While this allowed me to move forward with my project, it is completely unacceptable that I would have to do this.

I would hope Camtasia is reading these comments. I just signed up for a 30 day trial and if this is an issue with Mac I will not be purchasing.

I JUST purchased cam for mac after having used PC version several years ago with great ease. Like the others in this post, I find that podcasts I produce are approx 10x larger than equivalent produced via other means.  Should I just tell admin in my department to save their money and NOT buy Cam for Mac for anyone else?  Or is there a solution that we all are missing?  I am NOT interested in becoming particularly tech savvy here.  I'm interested in producing podcasts of the size and quality of those I produced using Doceri two years ago. The ability to do all this nice careful editing and annotating does not make up for files that are too big for the purpose.

I think this is totally unacceptable. It is hard to believe that TechSmith does not know about the fact that Camtasia on Mac is unusable. The file sizes it creates are horrifying beyond believe. I can only recommend to use NCH Debut instead. It create a 16MB file for exactly the same video, length, etc. where Camtasia takes 130MB+.

TechSmith, first step for you is to acknowledge the issue. 2nd step is to fix it. At least I would do that if I were interested in the Mac market.

I couldn't agree with you more, Oliver.  What is additionally frustrating is that this is a long standing problem.
Thanks for the recommendation on NCH Debut - I will be trying that now.

I used handbrake to reduce the file sizes.  That seems to work.

Thank you for the article. The problem is that one can follow this advice on Mac and PC and get vastly larger files on Mac.  I was hoping that Camtasia 3 for Mac would resolve this file size issue, but in my one test so far it has not. For one thing there is no video compression setting as there is in Camtasia Studio (PC).

Same here. 3 hour presentation produces at 1.5GB on PC.

On Mac it exports to 7GB!

Render time on Mac is far superior - 45 min vs 3 hours on PC, which is why I got it in the first place.

What's the point of saving time on the render if you quadruple the upload time to s3...

Out of the pot into the fire.

Anyone heard any update about this from Camtasia? It has been years since this issue was first reported here and it is still a problem.

I'm going to send feedback to Support about this, but I wanted to chime in. I used Camtasia Mac to put a 2-second front end on an 11 MB video (that was already MP4), and the resulting file was 120 MB! I changed the output resolution, and still got 64 MB. That's nuts.

I gave up on this. I'm generally on Mac, but I keep a PC just to produce videos. I hope someone will chime in if/when it is resolved.

I contacted Camtasia support and this was the response I got after explaining the issue:

"I will say that this is an issue the team is looking for better ways to address. Unfortunately the current issues is more related to the compression libraries that are used between the two platforms, and the licensing we have for our current compression libraries used between Mac and Windows. With that, we are looking to add a more unified renderer that would allow for fast compression and similar file sizes between the two versions."

They also directed me towards the same link listed above in this post (https://support.techsmith.com/hc/en-us/articles/203727328) but I told them that following the advice there I was still getting much larger files on Mac, and the video quality was often worse when I was getting the file size down from the bloated default.
