For presentations, screen sharing is important as are granular options such as the ability to share just one application (Microsoft PowerPoint, for example), document, or image or share your entire desktop. Most of the video conferencing services in this roundup also offer a whiteboard tool, which you can use to sketch out ideas or take notes during the meeting for everyone to see. You also need to consider what the participants are able to do, such as share their screen, enable their webcam, sketch on a shared whiteboard, and even take over the presentation. Think about how much actual collaboration you'd like in your meetings.
ActionDirector is one of the most popular video editing apps on PC. It's also available on Android. It does the basics. You can import clips, edit them, and render the video. You can do things like add your own music, trim and cut video, add text, employ slow motion, and more. It's one of the few video editor apps that also supports 4K video. You'll have to check and see if your device supports it, though. The developers have a nifty tool linked in the Google Play Store to see if yours can. It also gets frequent updates.
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.
