Frequently Asked Questions
An FLV file is stored within the FLV container format. This format is used for streaming video content on the Internet when using the Adobe Flash Player.
FLV is appropriate for uploading and playing videos on the web. But FLV files can’t be played on PCs without additional codecs and are not supported on some mobile devices. So if you want to watch a video on your device, MP4 is a good choice since it’s a universal format supported by almost every player.
FLV is not natively supported on iPhone. But you can install special players that can run FLV files. Another option is to convert FLV files to MP4 or another format that’s compatible with the iPhone.
FLV files are encoded with lossy codecs such as VP6 or H.264. For this reason, FLV files are relatively small in size and can be easily transmitted over the Internet. If you’re looking for a more efficient coding format, try HEVC – in comparison with H.264, this codec provides better data compression at the same bit rate.
The main advantages of FLV files are that they can be played in web browsers and are usually quite small in size.
