How to convert FLV to WebM?

If you have been dealing with online media materials a lot, you are probably very familiar with the FLV file extension and the WebM file extension.

Despite FLV is also a common format for online embedded videos, when you need a WebM, you still have to find a way to convert FLV to WebM. And that raises the question: How to convert FLV to WebM? Well, generally speaking, converting a video format to another shouldn’t be too hard. But when it comes to FLV and WebM, as they are not supported by many video converters, the problem becomes trickier than usual. If you are going through the problem of not being able to convert FLV to WebM, then I’m sure this article will help you out. Because in today’s article, we will not only introduce multiple tools that you can use to convert FLV to WebM, but also give detailed instructions on how to convert FLV to WebM exactly.

Part 1: FLV vs WebM

Before we start to talk about how to convert FLV to WebM, let’s get to know these two media formats a little better so that you could have a better understanding of what we are doing here and why we are doing it.

FLV, short for Flash Video, is a video format that uses Adobe Flash Player or Adobe Air to transmit video or audio through the Internet. FLV is very popular on the Internet. Almost all of the online videos embedded on webpages are in the FLV video format, including the video materials on YouTube, Hulu and other blogs or websites. There are two different Flash Video file formats: FLV and F4V. So, if you can extract or download a video from a webpage directly, chances are the raw video you get is either in the FLV format, or in the F4V format.

WebM on the other hand, was specially designed for HTML5 uses. Being announced at the Google conference I/O 2010, WebM is an open-source container format designed to replace other video formats like MP4 on the Internet. WebM uses VP8 and VP9 to decode video content and Vorbis and Opus to decode audio content. Because of that, WebM media files are highly compressed but very suitable for HTML5 purposes. In an HTML5 page, WebM media content can be loaded fast and can provide a high video and audio quality at the same time. When dealing with HTML5 pages, WebM media files have irreplaceable advantages over FLV files. So, if you have an FLV file, you are going to need to convert the FLV to WebM in order to get the best performance. So that brings us back to the question: How to convert FLV to WebM?

Apparently, the whole idea of this brand design is allowing customers to try the video converting function online, if they like it, they can download the converter program. However, the online converter turns out doesn’t perform so well. The supported file formats are so limited that even a lot of mainstream formats cannot be recognized.
