You might have some MOV videos or movie clips from your camera saved on your computer, especially if you use a Mac. These files often have great quality, but they can be hard to share online. Many video-sharing sites, blogs, and forums do not accept MOV files. It is where converting MOV to FLV becomes useful.
FLV is a popular format made for easy online delivery. It is accepted by almost all major video sites and loads faster for viewers. By changing your MOV files to FLV, you make them easier to upload, share, and stream without losing too much quality. This way, more people can watch your videos without running into playback problems.

Part 1. MOV vs FLV
When you save or share a video, the file format matters a lot. Two common types are MOV and FLV. Both store video and audio, but they are not the same. MOV is often used for high-quality videos and editing. FLV is made for fast streaming on the web. Each has its own strengths and limits. Knowing the difference can help you pick the right one for your needs.
Here is a simple table to compare them:
Feature | MOV | FLV |
---|---|---|
Full Name | QuickTime Movie | Flash Video |
Developer | Apple | Adobe Systems |
Main Use | Video editing and high-quality playback | Web streaming and online video |
Video Quality | Very high | Good, but smaller in size |
File Size | Large | Small to medium |
Compatibility | Works best with Apple devices and software | Works with most browsers that support Flash |
Editing Support | Great for editing in pro software | Not ideal for detailed editing |
Streaming | Not built for streaming | Made for smooth streaming |
Playback | Needs QuickTime or compatible players | Needs Flash Player or a converted format |
Compression | Can keep high detail with less compression | Use more compression for faster load |
Best For | Film projects, pro video work, and archiving | Online video sharing and faster loading clips |
