- Uncompressed videos use normal algorithm to store all pieces of information (piece by piece, without sorting), which can take up massive PC resources (both memory and space). For both servers(website host machines) and end-users(PCs), it is no good news: Firstly, uncompressed video storage wastes bandwidth. Secondly, retrieving needed information is more difficult than retrieving organized information!

Q: Why are uncompressed videos slow or failed to load? A: Uncompressed technology uses repeated messages to ensure a piece of message has been sent and received correctly. Message-transferring efficiency are determined by 2 factors: message sending/receiving order & how many messages are sent/received each time.

Part 3: How to Produce a Compressed Video Fast? [A Happier and More Practical Way]

A large group of experienced reviewers suggest you using video compressor to produce a compressed video in another format. But is it the best approach? Won't it have any side effects?

Sure! Here Are Reasons:

a.It's useless when videos can't be used or played on end-user devices:

- Many video compressors reduce video size by converting it to another video format. There are tons of dizzy video formats, many of which get rejected by TV, smartphone, video player, or streaming sites(i.e., YouTube, Facebook, Twitter, Ins). The reduced video won't be useful!

b.Converting video doesn't change anything except for video format:

- Piles of video contents aren't well optimized. When you compress the video, perhaps you compress the video content as well, but you have no idea of this. After the process, video length gets shorter, and video content becomes more condensed.

Our Suggested Solution Is:

Instead of converting video to a rare format, FlexClip video editor will edit and compress your video to MP4 format using codec H.264 (H.264 is a compression algorithm in technology).

You can easily add necessary video clips and royalty-free music. Just hit [+ Storyboard] > [Add Video] > select a part of video, and that's it.

After you finish every detail, press [Export Video]. You'll have a free option and 2 advanced options to download a compressed MP4 video.

Unlike many video compressors keeping you waited hours for download, FlexClip roughly takes minutes to do it. That's a huge plus!
