How to Convert AVI to MP4 on Mac Using a Pre-installed App?

iMovie is a Apple-based video editor with the ability to edit video footage and export it as MP4 or MOV.

But not all types of AVI videos are supported by iMovie. AVI is a multimedia container format, not a specific type of file. It can be compressed by a quantity of codecs. Those AVI videos encoded with Indeo, native DivX, Cinepak, ALaw 2:1, etc. can’t be put onto iMovie.

So before turning AVI into MP4 on Mac, check if it’s an iMovie compatible video codec.

1. Launch iMovie. Drag and drop AVI clips into it.

Before macOS transitions to 64-bit technology, the AVI file imported into iMovie requires conversion. The converted format in iMovie library will be compatible with versions of macOS after Mojave. Note: macOS Catalina doesn't support such conversion. You can click 'Convert' or 'Skip'.

2. In the top menu, click “File” > 'Share' > 'File…'. Alternatively, click the 'Share' button in the upper right corner > 'File'.

3. In the file dialog box that pops up, adjust the resolution, quality and compression settings.

Don’t set the quality as “Best (ProRes), otherwise the output format is MOV.

4. Hit on 'Next', name the exported iMovie MP4 file and specify the location where to save it.

5. Click “Save”.

2. Find Terminal app and initiate it.

3. Drag and drop FFmpeg to the Terminal.​

4. Type the command –i. Add the original AVI video into terminal. Then enter xxx(the output file name).mp4.

Individual AVI file conversion: -i input.flv xxx.mp4.

Batch processing multiple AVI files: for i in *.avi; do name=`echo '$i' | cut -d'.' -f1` echo '$name' ffmpeg -i '$i' '${name}.mp4' done or for i in *.avi; do ffmpeg -i '$i' '${i%.*}.mp4'; done.

People Also Ask

1) Can I turn AVI into MP4 on Mac with VLC?

Yes, but not straightly.

Although VLC gives you an output option: Video- H.264 + MP3 (MP4), it's actually M4V. The M4V and MP4 formats are very similar. The main difference is that M4V might optionally be encrypted by DRM copy protection.

You can change the file extension to .mp4, but the video and audio are often corrupted or coming with some serious lagging. If this happens, try to customize the profile:

• Video codec H.264, keep original video track
• Audio codec MPEG 4 Audio (AAC), keep original audio track

In addition, when converting large AVI files (more than 500 MB), VLC stops short of the full conversion. Trials in tainted space urbolg.

Obviously, VLC is not a good AVI to MP4 converter for Mac to get the task done.

2) Can HandBrake transcode AVI video to MP4?

HandBrake is a free video transcoder to convert videos from nearly any format including AVI, unprotected DVD, and BluRay sources. It lets you add multiple AVI files to queue, and transcode them to MP4 in batches.

But it's not a perfect AVI to MP4 transcoder for Mac.

• Can only convert AVI to two formats, MP4 and MKV (no more output options).
• The conversion speed is a bit slow.
• Even with H265 compression, the file size increased after conversion. I tested a 26.6MB AVI file. Through Handbrake x265 transcoding, the output file size is 64.2MB (more than twice the size of the original), whereas the size is 20.4MB (no quality loss) via Cisdem Video Converter.

3) Can QuickTime convert AVI to MP4 on Mac?

Yes, you can do it, but two conditions need to be met:

• Use QuickTime 7 Pro (paid and not available on macOS Mojave or later)
• The AVI can be imported to QuickTime 7 Pro. AVI has dozens of codecs in hundreds of combinations, some of which are not supported by Apple software. (Refer to the iMovie mentioned above)

If both of these met, then you can:

1. Open AVI in QT 7 pro.
2. Navigate to the “File” menu.
3. Click “Export” to reveal the format list.
4. Choose “Movie to MPEG-4”. Necessarily, fine-tune the video parameters.
5. Save the video.

QuickTime X doesn't offer video conversion option. However, when you open a playable AVI file, it will automatically convert AVI to MOV.

4) How to open AVI on Mac?

For those who are using Mac OS X 10.4.7+ and QuickTime 7 or previous, you are able to install Perian - the third-party component packages of QuickTime Player.

The best way is to look for alternative to QuickTime. Both VLC and Cisdem Video Player are free to play AVI files on Mac.
