Camtasia (Windows): Guidelines for working with 4K content

Editing 4K video footage requires quite a bit of computer power.  In order to guide users to the best 4K editing experience we've included some information below that may help.

What type of machine was used in Camtasia's 4K testing?

Processor: Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz (8 CPUs), ~3.4GHz

Memory: 16GB RAM

Graphics: NVIDIA GeForce GTX 745

  • Display Memory: 12197 MB
  • Dedicated Memory: 4035 MB
  • Shared Memory: 8161 MB

What was the performance like with the specifications from the machine above?

In our testing editing both 4k screen recorded content as well as full motion 4k content generated from an iPhone performed very well.  Our testing was limited to a single 30fps 4k video playing at a time or two 30fps 1080p videos playing simultaneously.  Playback performance appeared smooth even after adding multiple effects.

Can I still edit 4K video if my machine does not meet the specifications above?

Nothing in the software prevents you from editing 4K content.  However, on lower powered machines the playback performance could appear to be choppy and working with the software in general could be slow making it difficult to make edits. If editing 4K content is something you would like to accomplish we do recommend a machine with similar specifications as the computer above.

What are some other tips to make sure I get the best 4K editing experience?

  1. Edit on a 4k monitor to reduce any scaling that would occur on a smaller monitor.
  2. Make sure your project settings are set to 3840x2160.  To make that change click on File > Project Settings > Custom.
  3. Always have the source content on a local hard drive.  Using an SSD drive will help even more.
