So to solve this problem, we come to show you multiple methods of how to change a video file type to the one fitting your needs of sharing, playing, and editing on Windows 10, Mac, iPhone, Android, and online. Just keep scrolling down the page.

1. How to Change a Video File Type VideoProc [Windows, Mac]

Supported OS: Windows 10/8/7, Mac OS X 10.6 and later

Best for: converting videos to any format

VideoProc is a piece of simple, light, but robust video converter software. Videos from iPhone, Android, DSLRs, GoPros, DJI, or downloaded online, can be easily accepted as it supports 370+ formats including MP4, MKV, MOV, AVI, WMV, FLV, HEVC, H.264, MP4G-4, AV1, VP9, ProRes, etc. Thus you can convert all sorts of videos, like MOV, AVI, WMV, and MKV to MP4 to share, play, and edit videos with zero error.

Another notable feature is its full GPU acceleration tech. Tests from its official support team show that, an HD video format conversion reaches up to 47x real-time faster and a 4K video conversion up to 7x faster than others.

In addition to customizable settings for power users to change the video file type to MP4, MOV, etc. without quality loss, VideoProc has worry-free presets for beginners which are categorized by devices (Mac, iPhone, Android, Xbox, PS, etc.), software (iMovie, iTunes, Final Cut Pro, etc.), and video platforms (YouTube, Facebook, Vimeo, and general web video).

Now download VideoProc to start to change video format in a few clicks!

Step 1. Import a video file into VideoProc.

Double click the icon of VideoProc on the desktop to launch it. Choose "Video" to enter its video conversion tab.

Now you need to choose a target format for your video. In VideoProc, you can do this by

  • Clicking "Video" at the bottom and select a video format with a proper codec.
  • Clicking "Target Format" and choose the file type in terms of your device (iPhone, iPad, Android, Xbox, TV…) or specific use (YouTube, Facebook, Final Cut Pro…).

Step 3 (optional). Edit the video before conversion.

Tips:

Click the gear icon to open the video codec option and drag the slider to the right side. This is to tell VideoProc to calculate a proper bitrate for your video and can prevent it from being degraded after the conversion. It will also show the estimated file size right above the quality option.

Step 4. Start to convert the video and export it from VideoProc.

Browse to select an output folder for your video. Check the box under "Hardware acceleration Engine" so to boost the conversion process. When everything is done, smash on the big "RUN" button to start changing the file type of the video.

Bonus: How to Change Video Format without Converting

Actually, this question is about video re-encoding. If you choose another codec for your video, it is impossible to convert the format without re-encoding because it completely changes how the video is compressed.

But if you just want to change the video format container, then, VideoProc has an "Auto Copy" mode to do this for you. It will keep the 1:1 quality of the source video and finish the conversion in a super-fast manner.

2. How to Change a Video File Type in iMovie [Mac]

Supported OS: Mac

Best for: converting MOV to MP4, and MP4 to MOV on Mac

We often use iMovie as a free video editor on Mac, but by skipping the editing steps, we can also use it to convert video formats. However, compared with other video converters, iMovie supports fewer video formats. It does not accept WMV, MKV, and WebM videos. But if you are looking for a quick conversion between MOV and MP4, it is worth a try.

Here's how to change video format in iMovie:

Step 1. Open iMovie on Mac and choose to create a movie project.

Step 2. Add a MOV video to its timeline. Note that, iMovie converts one video per conversion. If you load multiple videos to the timeline, they will be merged into one file after the conversion.
