by Christine Smith • 2023-04-18 14:41:17 • Proven solutions

If you have problems in uploading your AVI videos to some video sharing sites, you may want to convert AVI to FLV file beforehand. It's not only YouTube that's notorious for its uploading format, but it's the same standard across other sites too. The main reason is due to its wide availability of Adobe Flash Player in the major web browsers. Besides that, an FLV video file format is smaller in terms of file size compared to an AVI and hence, would not take up a lot of storage space.
