Part 1: Uncompressed Video VS Compressed Video

Jaw-Dropping News: Uncompressed videos can use up PC resources!

Uncompressed videos adopt normal algorithm to keep all piece of information (one by one without sorting), which can take up massive memory and space. To servers(website host machines) and end-users(PCs), this is never good news - It wastes bandwidth, plus retrieving needed information, in this case, is hard!

Tip: Why are uncompressed videos slow or failed? - Uncompressed technology uses repeated messages to ensure one message has sent and received correctly. Besides, 2 factors determine message-transferring efficiency: message order and the number of messages conveying each time.

If you reduce the video size in a quality-guaranteed way, then you'll have at least 2 significant advantages:

  1. Load video faster on user computer - To ensure better user experience and engagement.
  2. It's more platform-friendly - Make your video appear more friendly to YouTube, Tiktok, and Google.

Part 2: How to Produce a Compressed Video Fast? [A Happier and More Practical Way]

A large group of experienced reviewers online would suggest you find the answer from the list of a bunch of video compressors. (We've rounded up free proven video compressors in Part 3.)

But seriously, is grabbing video compressor the best approach?

Uh, We don't think so!

Here Are Our Reasons:

a.It's pointless when video can't be used and played:

- Many video compressors reduce video size by converting it to another video format. There are awful groups of dizzy video formats, many of which get rejected by TV, smartphone, streaming sites(i.e., YouTube, Facebook, Twitter, Ins), or even mainstream video players. It's useless!

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

- Piles of video contents aren't optimized well. When you compress the video, perhaps you can compress the video content as well, by cutting video that's not necessary. After the process, video length gets shorter, and video content is 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 as video storyboards: Hit [+ Storyboard] > [Add Video] > select a part of video, and that's it.


  1. If you would like to use some video texts, then check out FlexClip Text function, which gives you tens of video texts, including those "logo + text" items.
  2. FlexClip also gives users the freedom to search and re-use extensive videos and photos, without getting into copyright issues.

After you finish every detail, press [Export Video]. You'll have a 100% free option and 2 advanced options to download a compressed MP4 video, without any watermark.

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