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.
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.
iMovie is a part of Apple’s own suite of products for iOS (and macOS), and is a great video editor app for iPhone that you can try. While you may want to use a more powerful editing software on your Mac, iMovie is more than capable of handling video editing on the iPhone. The app is included with the newer generations of iPhones, and you can use it right out of the box to make some awesome videos directly on your iPhone.
OPlayer Lite is currently one of the best video players for iPad. It has excellent support for almost all formats (the latest update includes MKV support too). There’s an AC3 issue with the current version though — still, a far better player than many others out there. The decoding can be particularly tricky with other apps, but Oplayer appears to handle it quite well.
Another handy feature to look for is support for Alexa voice commands that let you view a doorbell's live stream on an Amazon-enabled display. Once you've enabled the skill, simply say "Alexa, show the front door" to launch a live stream on your Echo Show or Fire TV-enabled TV or monitor. Similar voice commands are also available using Google Assistant.
