Best and Easy Ways to Learn What Is an FLV File

by Kayla Morrison • 2024-06-18 18:07:27 • Proven solutions

Although FLV files are standard, they are not compatible with most electronic devices like MP4 and MOV. Fortunately, there are tons of programs over the internet that can convert FLV to any other digital format that you can think of. But before we start transcoding, I’ll tell you the answer to the question: what is a .flv file, and why it’s vital to transcode it to another acceptable format. Let’s dive in!

Part 1. What Does FLV Stand for

So, what is FLV? Developed by Adobe Systems, FLV is the acronym for Flash Video. Typically, this file format has a .flv extension and is used to stream videos on online file-sharing sites like YouTube, Vevo, Vimeo, etc. FLV videos use the H.263 standard encoding with an MP3 audio file type. You can open FLV videos using selected-few dedicated desktop media players like VLC, MPC-HC, and 5KPlayer.

Sadly, most video streaming sites have ditched the Flash Video format in favor of the more modern HTML5. Even worse, iOS devices still experience problems opening FLV files. As if that’s not enough, sites streaming FLV files will take much longer to load. So, if you want to have a smoother playback with Flash files, you better convert it to another manageable format like MP4.

Part 2. Ultimate Solution to Play and Convert FLV File to Any Format

Because of FLV files’ poor compatibility issues, it’s a no brainer to encode them to a universal format such as MP4. If that’s the case, you’ll need to install a professional third-party FLV converter like Wondershare UniConverter It’s a simple app to install and use. Apart from converting FLV to other standard formats, it also features a fantastic media player that supports all video formats. You can also edit videos, download FLV files from file-sharing sites, and burn to disc. Simply put, Wondershare FLV Converter is the perfect all-in-one tool.

Part 3. Other 6 Recommended Free Online FLV Converters

I understand that sometimes you might have small video files to convert, or you may simply not have enough time to install an app. In that case, I want to recommend to you the best possible online FLV converters currently.

Step 1: Tap the Choose Files to import videos.

Step 2: Edit your FLV video by entering the frame rate, bit rate, pixels, and more. Once you’re done, go to the final step.

Of all the online FLV converters here, Zamzar supports the most extensive format list. It supports more than 1,000 formats, FLV included. It’s also quite straightforward to use, just like most FLV converters here. However, Zamzar doesn’t offer video editing services. In addition to that, it has a maximum of 200MB conversion size.

Step 1: Click the Add Files to upload your video, then open the format list to select a format.p>

Step 2: Lastly, click the Convert Now button. It’s that simple!

6. Convertio

Finally, we have Convertio, which claims to convert over 300 file formats, FLV included. It has a simple interface and supports video editing as well. You can edit clips by cutting, resizing, changing the frame rate, etc. But the ugly part is the small conversion size of 100MB.

Step 1: Tap the Choose File to import your FLV videos.

Step 2: Click for > The video > choose a video format. You can also edit by hitting the settings icon.

Step 3: Now, click the red Conversion button to begin transcoding.
