Camtasia Mac Takes Too Long To Render Videos

  • Updated 4 years ago
  • Solved
Rendering a video on Camtasia Mac is so much slower than Camtasia Studio 7. I have an 8 core Mac with 16 Gb of memory running at 64bits and a 4 core windows machine with 4 Gb of memory running at 32 bits. I use both platforms but would prefer to use the Mac however it takes about 10 times longer to render the final video on the Mac. It's just not usable so I have to do all of my recordings on the PC. I haven't seen an update for the Mac version for quite a while and have purchased a 3 year maintenance agreement. Is something being address to solve this problem?

Hi mdrather,

Thanks for letting us know it's really slow for you. Sorry it's causing you frustration.

Would you be able to provide more information?

Could you let us know:
- the recording size on your Mac?
- the canvas size on your mac?
- how long the video on your Mac is?
- how did you export on the Mac? (e.g. Export, Advance Export, YouTube, etc.)
- the recording size on your PC?
- the editing and publishing dimensions on your PC?
- how long the video on your PC is?
- how you produced on the PC? (e.g. Web, Custom [& what settings], etc.)

I know that's a lot, but there are so many things that effect exporting speed, and this information will help us track down why it's so slow for you.

Thanks!

Hello, I will have to get back to you with the specifics however I can tell you that I used the exact same parameters on both Windows and Mac when I was trying to diagnose the problem. I was confused why I was having such difficulty with the Mac version so I had to be sure that I was using the exact same settings, both recording and rendering.

Thanks,

Mike

I have a similar issue. Currently running Camtasia on an iMac with a quad i7, 8GB ram. I recorded some videos in full HD yesterday and it took me almost an hour and a half to render a 40 min video into .MOV and over 3 hours for a 2 hour video

- Recorded canvas size: 1920x1080
- I used advanced export to .MOV

Is it normal to take so long to render?

Thanks in advance,
George

Hi George,

Are you exporting at 1920x1080 as well or scaling it beforehand?

Also, are you recording your desktop and application use or full-motion video (i.e. stuff recorded with a camera)?

While I've never exported anything that long from Camtasia, the export times you're seeing for that size and type of video doesn't surprise me. If you are indeed exporting a full-motion video at 1920x1080 that's about 50 million pixels, most of which are changing every frame, that needed to be encoded for every second of video. All of that plus encode in a way that makes the file size be less than 1/10th of what it normally would be without encoding. That's a lot of crunching.

That said, we'd like it to export faster, too. :)

Hi there, thanks for the reply :)

Take a look http://webdesign.tutsplus.com/tutoria...

Scroll down to see the videos in question. I'm just recording a part of the screen - 1920x1080 and it's just my desktop + sound from mike.

While a huge fan of Camtasia on the recording end, and how quick it is to save videos at the point of recording....

I too am having horribly slow times rendering out a 15 minute screen capture at 720P resolution (1280x720). In exporting to MP4 and H.264, it's doing two passes, and the overall export time is 2x real time. A real bummer when doing 30 minute tutorials, where rendering and uploading to Vimeo might be a 2 hour affair. Ugh.

I am also experiencing long export times. It seems even longer than what is reported here. It takes about an hour to export a 10 minute video, even after scaling down 640x360 and reducing the frame rate to 15. I'm doing advanced export. Am I doing something wrong?

I have the same problem. I have an hour long video at 1920x1080 that I am trying to export to quicktime .mov. I ran it in multi-pass. The first pass (where it says 100% complete) took 4 hours. Then it started a second pass. I am 2 hours in and it is 22% done. This is completely un-useable.

I just downloaded the 30 Day Trial for Camtasia for MAC.

I've recorded a 7 minute tutorial & have been trying to export it FOREVER.

I recorded it at full screen but the progress bar shows NOTHING even after 30 minutes.

What is the deal? I like Camtasia & just learning it BUT>>>>>

It this broken or can it be remedied ASAP?

OR should I just save myself hours of headaches up front & start over with another software product?

I need to know ASAP.

Thanks.

Sounds like you've hit a bug. Our tech support should be able to help you see if there's a solution: http://techsmith.custhelp.com/app/ask

For those who are exporting to a .MOV format using the Quicktime setting, this is using Apple's encoder and is known to be slow.

Unless you must have a .MOV, I would suggest using the default "Export..." option from the Share menu, or at least the "Main Concept MP4" (in 2.0) option in "Advanced Export." These use a much more efficient codec and are noticably faster.

Hi Conan -

Thank you - I certainly appreciate your response - this is not the correct solution.

I just got off the phone with TechSmith support via phone - Robert is extremely helpful - and found that it is a code conflict that is causing the failure to export.

For ANYONE experiencing a TOTAL FAIL to export - even when selecting the Main Concept MP4 - here is the answer:

The CODE CONFLICT is with a file called CT loader - which is found in Library under Input Manager.

Delete this file - but do a search to see if it's found elsewhere. Then restart your computer.

This worked for me!

Thank you.

This comment above does give me some hope.
I have tried to render a 2 hour video about 4 times over 2 days and no luck.

I cut it in half and tried again, but in the second pass it is hanging at 94%.

It's frustrating in that I can't afford this level of delay since I produce weekly content.

I am going to try this CT loader solution and see if it works.

I hope it does.

Is it stuck there or just going really, really, really slow? If it is stuck, I'd open up a ticket with our tech support (http://techsmith.custhelp.com/app/ask) to see what they can find out.

If it is continuing to advance at that pace, I'd check two things:
1) What's the size of your canvas?
You can find this by going to the Edit menu > Adjust Canvas...
Its size will make a HUGE difference in how long it takes.
For instance, a video at 720p (1280x720) has 2.25 times the number of pixels as a 480p (853x480) video, so could likely take about 2x as long to export. Likewise, a video at 1080p (1920x1080) has 2.25 times the number of pixels as a 720p-sized video, so could likely take 2x as long as the 720p video and about 4x as long as the 480p-sized video.

2) How are you exporting it?
Unless you have a good reason to (e.g. you need something besides MP4 or need a very specific lower-level settings) and your really know about codecs, bitrates, keyframes, etc., you should be exporting with the standard Share>Export (cmd+e) option via the menubar. If you're using the Advanced Export... option to optimize size or rendering quality/time, you'll very likely be frustrated.

Hope that helps,

Conan.

Are there any options to load the camtasia files into another video editing software to fasten the export process?

thank you in advance

Unfortunately, no. Not without exporting it first, which kind of defeats the whole purpose.

It seems to me that no one at Camtasia ha taken the time to address the REAL PROBLEM which is a CODE CONFLICT - as per my post above.

Pick up the phone and call Camstasia Tech Support and ask for Robert. He was kind enough to solve this problem.

Supposedly someone at Camtasia was supposed to post the solution here - but I see no one has.

I would suggest that this problem is not "solved" until customers agree that rendering times have improved. This is a perception issue, not a feature issue, that can only be solved when the pain isn't felt by the user. Mike or Conan, could you consider opening this issue again to keep collecting customers sediment?

i'm using Camtasia for Mac as an iMovie alternative, because the new iMovie v10 bites!

i really like camtasia but i too have been extreeeeemly frustrated with the export time. 

i have my canvas sized at the preset: YouTube HD/720p (1280x720).

i import an MP4 video file from my sony handycam at the preset format: AVC Coding, 1280x720, 
and separate MP3 audio recorded directly into Quicktime Player X at default format: AAC, 44100 Hz, Stereo, from a mixing console.

it's usually around a 30-40 minute recording, and i use the Share menu's Export Advanced with the default MP4 settings.
this export process consistently takes between 1-2 hours!

anybody have any tips/tricks/workarounds to get a good export that takes less than the time of the recording?
thanx.

Very well documented problems with this product, multiple users, and I am dumbfounded that all of Conan's responses imply that there is something on the user's side that is making the rendering so slow. I'm using Filmora Wondershare in addition to Camtasia, and Wondershare can export between file formats in 1/8th the time. Developers, this is your issue, not ours. I too am on a trial version, thank God. There will be no purchase.

Hi James,

Thanks for your feedback and letting us know of your frustration.

I'm sorry if my replies infer that the problem is on the users' side. My intent was to, as a long time user of Camtasia for Mac, be as helpful in the present (of 3+ years ago) as I could with the current state of the software. As Chris, you, and others have stated, there do need to be improvements to the export process--and there have been many regular advances since this thread was opened. However, it does always need to be worked on, as you're seeing.

Perhaps of interest: rendering performance is one of the significant improvements that the Camtasia team has been working on for the next major release: https://feedback.techsmith.com/techsmith/topics/techsmiths-camtasia-future-roadmap
