Have problem in playing YouTube FLV videos offline on programs such as iPhone, Sony Xperia, etc? Take it easy, all of your problems can be easily solved here.

1. How to Play YouTube FLV Videos
Offline

2. As the global leader of video-sharing website, YouTube has brought
us much convenience and abundance. It seems that we can find
almost all we want there: music, video, news, information, etc. The
number of YouTube monthly active users has reached to over 1
billion. Besides, more than 6 billion hours of video are watched each
month on YouTube—that's almost an hour for every person on
Earth. With so many people hanging there, sometimes, it's not as
smooth as we expected to enjoy YouTube FLV videos online.
Alternatively, it is a good idea to download and play the videos
offline.

3. It is always easier said than done. Here are the questions asked by
some people:
1. "Can someone tell me what's a .flv file and how to either make it
into a .avi file and playable in Windows Movie Maker or simply to
make it playable. I got a cool little application called download
helper, but everything it saves for me is in .flv and I have no clue
what to do?".
2. "I just got some YouTube videos(in .flv format), I cannot figure out
the right way to play them on my smart phone (Sony Xperia). Please
help!".
3. "How can I play YouTube FLV videos on iPhone 5 please?"

4. Well, before we get started, it's necessary to have a glance at what
FLV format is. FLV, short for Flash Video, is a video format used to
deliver videos over the Internet using Adobe Flash Player 6/7/8/9.
FLV content may also be embedded within SWF files.
Currently, there are some brand websites using the FLV file format
which include: YouTube, Google Video, Yahoo! Video, MySpace and
Reuters.com.

5. Basically, an FLV file can be opened or played by some programs
natively such as Adobe's Flash Player (version 7 and
later), RealPlayer, VLC, MPlayer, and other popular media players.
Besides, Adobe Premiere Pro can support the editing of FLV file
well. However, if you would like to play an FLV file on other
programs such as Windows Movie Maker, QuickTime or portable
mobile devices like Sony Xperia, it is a must to convert the FLV file
to another file type.

6. For example, transfer FLV to Xperia friendly video format like
MP4, convert FLV to AVI for Windows Movie Maker, etc. In
addition, Apple devices like iPhone 5 has also turned down the
support for Adobe Flash Player, that is why iPhone users cannot
play the FLV files since they have to use iTunes to manage their
media data. In light of this, there is nothing we can do but to import
YouTube videos to iTunes before trasferring FLV files to
iPhone, iPad, iPod, etc. That is to say, we need to convert FLV to
M4V to make YouTube FLV videos acceptable by iTunes.

7. To solve all of the problems above, a professional and easy-to-use
third-party program is enough. Doremisoft FLV Video Converter is
the recommendable software specializing in handling the FLV file
issues perfectly. The process of conducting the conversion is as
easy as eating a pie, which goes like this: import FLV video file--set
output format--edit the video optionally--start to convert.
