Adobe Flash MP4 Multimedia (F4V) is a rather ubiquitous video container format because globally, most viewers of online videos use technology that is designed to play on Adobe Flash Player. In fact, F4V is often referred to as “Flash Video.” An F4V container compresses multimedia files with a codec and facilitates delivery of the files as streaming audio and video over the Internet.

 

How to open a F4V file?

On most platforms, F4V files open in Adobe Flash Player by default. On Microsoft Windows OS, Adobe AIR might be the default player. For guaranteed results on Mac OS X, and Linux/Unix, open F4V files with VLC media player.

 

It is important to know that Apple iOS devices do not support the Adobe Flash Player plugin. However, Puffin Web Browser is a free option that can bypass iOS’s restrictions.

Adaptive Multi-Rate (AMR) is a compressed audio file that is often used for speech coding. The AMR speech codec focuses on narrowband signals, which makes it ideal for voice recordings and radio. It is used regularly in Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS).

 

How to open an AMR file?

Since AMR files are often used on mobile phones, including for MMS messaging, most 3G mobile devices are able to open them. AMR also opens with VLC media player, QuickTime, RealPlayer, and Xine.

 

Other software, such as the free audio-editing software Audacity, can open AMR files. Download audacity easily at SourceForge.net. Because AMR files are heavily compressed and focused on narrowband signals, they are not suitable for music files.
