VivaVideo has a lot of impressive video editing features. The app is thoughtfully designed to help you create professional looking videos directly from your Android. You can choose from hundreds of user-friendly effects that range from stickers and filters to animated clips and subtitles. It has an inbuilt slow motion video maker and slideshow maker. The essential functions of cutting and pasting videos, trimming, merging clips, etc. can be easily operated.
Another impressive effect that has made its way into consumer-level video editing software is motion tracking, which lets you attach an object or effect to something moving in your video. You might use it to put a blur over the face of someone you don't want to show up in your video. You specify the target face, and the app takes care of the rest, tracking the face and moving the effect to follow it. This used to be the sole province of special effects software such as Adobe After Effects. Corel VideoStudio was the first of the consumer products to include motion tracking, and it still leads the pack in the depth and usability of its motion-tracking tool, though several others now include the capability.
Other features to look for include face recognition technology that identifies visitors by name, motion sensing technology that knows the difference between people, cars, and animals, color night vision video (most doorbell cameras use infrared LEDs to provide up to 30 feet of black-and-white video), and a choice of chimes that will help you differentiate between a doorbell press and a motion trigger. Some of latest doorbell cameras offer a pre-buffer feature that records several seconds of activity prior to when a motion sensor is triggered or the doorbell button has been pressed so you can see what happened just before an event.
Signal Private Messenger is one of the most popular privacy chat apps. It features end-to-end encryption for all messages, voice calls, and video chats between two Signal users. It focuses a lot on individual chats. There are group chat features, but it's mostly for personal use. This is one of the biggest differences between it and rival privacy chat app Telegram. Video calls worked fine in our testing so we have no trouble recommending them. It's a neat way to get some encrypted chats as well. The app is also completely free and open source. You can't really go wrong with it, but there are better video chat apps if you need group video chats.
