Video editing is one of the most computing-intensive activities around, so you'll want the best laptop or desktop you can afford if you're serious about cutting your own movies. Most applications help speed up the editing process by creating a proxy file of lower resolution, so that normal editing and previewing aren't slowed down by the huge full-resolution files.
Quik is from a newer generation of video editor apps. It's halfway decent if you need something simple. The way it works is you add up to 50 photos and video clips into the app. The app then analyzes them and spits out a short video from them. Quik contains about two dozen video styles and you can re-order and customize your video before you export it. It’s not nearly as powerful as something like Adobe Premiere Clip or PowerDirector, but not everyone needs something that intense. It's free to download with no in-app purchases.
Other measures of performance include startup time and simple stability. Again, video editing is a taxing activity for any computer, involving many components. In the past, video editing programs took longer than most other apps to start up, and unexpected shutdowns were unfortunately common, even in top apps from top developers such as Adobe and Apple. The stability situation has greatly improved, but the complexity of the process, which increases as more powerful effects are added, means crashes will likely never be fully eliminated, and they often raise their ugly heads after a program update, as I found with the latest version of Pinnacle Studio.
Other features I look at include the number of participants allowed on a call and the number of video feeds allowed simultaneously. The most generous is Adobe Connect, which is unlimited, but some offer as few as four participants at a time. Consider how important this is to your company. Most services let you record meetings, and a few let you edit the recording right within the software. These recorded meetings can then be used for your records or as webinars for anyone who missed the meeting or for new employees.
