why does camtasia become slow when I am editing large files?

  • Updated 6 years ago
I have a Camtasia Studio 7 project; the file is 60 minutes long from a PowerPoint recording. I am editing the audio to remove noises/unwanted speech etc. When I started editing at the begining, I cut a section and almost immediately Camtasia is ready to proceed; but as I get towards the end of the file, when I cut a section, Camtasia takes almost a minute before I can proceed and save the project and continue playing the file. This is slowing down my editing considerably. Is this an issue with Camtasia and large files or could it be a hardware issue? I have 8GB of Memory; Intel Core i7-2620M processor at 2.70GHz & 64 bit Windows 7.

Hey Steve,

The larger the file, and the more edits, callouts, etc. that you have, the more taxing on your system that is going to be. I assume it's being a bit jerky in the preview window as well. This should be solved when you actually produce the video out.

The easiest solution to this is going to be edit part of your video, produce it out, than import it back into the timeline on camtasia. That way you will be dealing with less callouts, edits, that sort of thing. It's not the best workaround, but it might just help.

We obviously increased performance in Camtasia 8 quite a bit. Feel free to take it for a spin here with a free, 30 day trial: http://www.techsmith.com/download/cam...

If you have any other questions, don't hesitate to let us know!

Thanks Logan, I will try your suggestion; but I will give Studio 8 a trial and will upgrade if it helps the problem.

Hi Logan, if I 'produce out' my video and then import the wav file to my timeline for final editing; when i produce the final video, is there any deterioration of the image quality? i.e. I am producing a new wav file from an existing wav file.

Thanks

Hi Logan. I tried Studio 8 and it did improve the speed a lot during editing.
But I did not like the changed way audio is displayed on the timeline; only half the waveform is displayed - it made it much more difficult to identify the parts I wanted to cut out.
So I have gone back to Studio 7 which has a much better time line display. I wonder why it was changed.

Yes, it's available in the most current version but you have to make sure you select it in the options:

What would be the best format to use when producing the video parts that will be brought back in to Camtasia. My concern is similar to the old "making a copy of a copy of a copy" problem -- each generation adds it's own "noise" to the final production.

Hey there, MP4 is going to be your best bet, but I wouldn't recommend doing it more than once or twice.

OK -- I've got some members of my team that are producing videos up to 90 minutes long (My internal protestations about peoples' attention spans aside). So I figured they could produce their 25% of their video as MP4, then work on the next 25%, etc. At the end, take their four MP4 videos that represent one quarter of the video and produce the final epic.

I've been experiencing similar issues this week, although my video is less than 30 mins long. I like the idea of producing parts of video, but what if you have interactions and quiz qustions spread across different chapters? Can I produce a video with hotspots that pause until a leaner clicks, and bring that back into Camtaisa? I'm using Studio 8 on a windows 7 PC
