Viber began life as a voice calling app. You used to be able to call people on the service along with regular phone calls. It has since evolved into a full-fledged messaging service. You can still make phone calls like you could before (for a fee). You can also text chat, video call, and more. It also features encryption on voice, text, and video calls between Viber users. There are a few extra fun features like hidden chats as well. It's a little bit heavier, similar to Facebook Messenger. However, it's otherwise not bad. The app isn't overly popular in the United States, but it's quite big Internationally. The in-app purchases are for things like stickers and other personalization items.
In the midrange, there's Adobe Premiere Elements, which is cross-platform between Macs and PCs, and offers a lot more features and lots of help with creating effects. Professionals and prosumers have powerful, though pricey options in Final Cut Pro X and Adobe Premiere Pro. Final Cut is a deceptively simple application that resembles iMovie in its interface and ease of use, but it offers massively deep capabilities, and many third-party apps integrate with it for even more power. It also makes excellent use of the Touch Bar on the latest MacBook Pro, as shown in photo above. Premiere Pro uses a more traditional timeline and adds a large ecosystem of companion apps and plug-ins. It also excels in collaboration features.
This great video editing app for iPhone takes you back to old times. You transform the video into a variety of vintage film styles with many combinations to choose from: black & white, sepia, color, vintage sepia, 20's movie or 60's home video, etc. You can speed up or slow down the videos. And several sound options like Video, Piano 1, Piano 2, Movie Projector, etc. are provided to add more feeling to your movie.
For those who have an iPhone or intend to buy one, iMovie is absolutely the best iPhone video editing app. It helps you turn the various video (including HD videos) you shoot into a gorgeous home movie with movie themes, titles, transitions and sound effects, etc. And you can also shoot a new video clip inside the application for better video editing on iPhone.
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.
