iMovie is friendly to videos recorded on Apple devices, but it is not a universal video editor. A file may fail to import because its container, codec, audio track, camera folder structure, or DVD source is not supported. This guide explains iMovie supported formats first, then shows practical ways to convert DVD and any video for iMovie without turning the page into several repeated tutorials stitched together.

Part 1. What File Types Does iMovie Support?

In most cases, iMovie works well with the following video containers and codecs:

  • Containers: MP4, MOV (QuickTime Movie), M4V, 3GP, and some AVI files;
  • Video codecs/formats: H.264/AVC, H.265/HEVC, MPEG-4, Apple ProRes, AVCHD, DV, HDV, iFrame, and Motion JPEG;
  • Audio: AAC is the safest choice for MP4/MOV imports.

However, the file extension alone is not enough. For example, one MP4 may import perfectly while another MP4 fails because it uses an unsupported video or audio codec. Some AVI files can be opened, but many AVI files encoded with DivX, Xvid, Cineform, or unusual audio codecs may still be rejected. Apple also notes that iMovie works with many DV/HDV camcorders, while some formats such as 4:2:2 10-bit H.264 are not supported. So, when you are not sure, convert the video to MP4 or MOV with H.264 video and AAC audio.

For higher-quality editing, you can also use Apple ProRes MOV, but it creates much larger files. HEVC is fine on newer Apple devices, yet H.264 is still the safer option when you need to move the project across older Macs, iPhones, or iPads.

Part 2. Why iMovie Won't Import Some Videos

Here are the most common cases behind an iMovie import error:

  • DVD sources: iMovie cannot import DVD discs, VIDEO_TS folders, ISO images, or VOB files directly. You need to digitize the DVD to MP4, MOV, or another editable video first.
  • Unsupported containers or codecs: Some files look common but still use a codec iMovie cannot decode, such as certain AVI, WMV, MTS/M2TS, or downloaded videos with unusual audio tracks.
  • Camera folder issues: AVCHD and other camera recordings may fail if the original folder structure is broken or only a single clip is copied out.
  • Unsupported codecs: A file extension may look right, but the internal video/audio codec may not be accepted by iMovie.
  • Damaged or incomplete files: A corrupted recording, interrupted transfer, or camera file copied without its companion files can also cause import failure.

Before conversion, you can also try updating iMovie and macOS/iOS, importing from the original camera folder instead of a single copied file, or testing the video in QuickTime Player. If the problem remains, transcoding is usually the cleanest fix.

Part 3. Best Format Settings for iMovie

For most users, the best iMovie conversion settings are:

  • Container: MP4 or MOV;
  • Video codec: H.264 for the best compatibility, or HEVC for smaller files on newer Apple devices;
  • Audio codec: AAC;
  • Resolution/FPS: keep the same as the original unless you need a smaller file;
  • Advanced editing: choose Apple ProRes MOV when you prefer smoother editing and can accept a much larger file size.

With the basics clear, you can choose a conversion method depending on where the source video comes from.

1. Convert Any Video to iMovie on Windows

WonderFox HD Video Converter Factory Pro is a beginner-friendly iMovie format converter for Windows. It can convert common videos, camera recordings, downloaded clips, and files that iMovie refuses to import to iMovie-friendly MP4/MOV. It also lets you set H.264, HEVC, MPEG-4, AAC, resolution, frame rate, bitrate, and other parameters. Batch conversion, GPU acceleration, compression, trimming, cropping, rotating, and merging are also available when you need more than a simple format change.

Download and install the converter on your PC. Then follow the steps below:

💡 Note: If your only task is converting a small video file to MP4/MOV, WonderFox Free HD Video Converter Factory is also a workable free option on Windows. Choose the Pro version when you need batch processing, more output control, faster conversion, or 4K/8K workflows.


2. Rip DVD to iMovie on Windows

DVD is a different case from normal video files. iMovie cannot read a DVD disc, VIDEO_TS folder, or VOB file directly. To edit DVD movies in iMovie, use WonderFox DVD Ripper Pro to convert the DVD to MP4 or MOV first.

Step 1. Insert the DVD into your DVD drive, open WonderFox DVD Ripper Pro, and click DVD Disc. The program will analyze the disc and mark the main movie title automatically.

Step 2. Open the output format list and choose an iMovie-friendly profile, such as MP4, MOV, or H.264. You can also adjust resolution, bitrate, frame rate, deinterlacing, subtitles, and audio tracks when needed.

Step 3. Set an output folder and click RUN. After conversion, transfer the ripped video to your Mac and import it into iMovie.

💡 You can also try HandBrake for local video files or unprotected DVDs. It is suitable for many MP4/MOV, camera recording, and general video conversion tasks.

This is useful when the video was recorded in HEVC but needs to be edited on an older Mac, or when the file was transferred from another device in a less common format.

Video Converter and Compressor is a handy iMovie format converter that can work on both iPhones and Android phones. It supports a wide range of video formats and allows you to quickly convert them to MP4, AVI, 3GP, MOV, and some other iMovie-compatible formats. Also, it enables you to modify the codec, frame rate, resolution, and output quality.

Step 1. Search and then install this converter on your phone from the Google Play Store.

Step 2. Open it and enter the Video Converter tool.

Step 3. Load the video from your folder to the converter.

Step 4. Click CONVERT TO and then expand the Format list to set an iMovie video format.

Follow the steps below to convert your video for iMovie free with CloudConvert:

Step 1. Open https://cloudconvert.com/ in your browser on any device.

Step 2. Select and upload your video to it by clicking the Select File button.

Step 5. Then click Convert to start converting your video to iMovie-supported format.

Online tools are convenient, but they are not ideal for large camera files, long DVD movies, private videos, or batch conversion because of upload speed, file size limits, and privacy concerns.

Part 4. What Format Does iMovie Export to?

Converting videos to iMovie-supported formats is essential for easy importing and editing. But what about exporting files in iMovie? Which export formats does iMovie support?

Please note that the Email, YouTube, Facebook, and Vimeo options do not provide direct access to sharing files on these platforms. Instead, these options create files on your device, and you will have to upload them later using the respective websites. Additionally, these options offer limited settings.

To have full control over your export, you can choose the last File option, which allows you to export iMovie videos as MOV or MP4. In the pop-up dialog box, you can change the file’s Title, Description, Tags, Format, Resolution, Quality, and Compress.

To save iMovie to MP4, you need to select Low, Medium, High, or Custom in the Quality dropdown list. For the best output quality, you can choose the ProRes option and the export will be saved as an MOV file.

FAQs

Q1. What is the best video format for iMovie?

MP4 or MOV with H.264 video and AAC audio is the safest choice for most iMovie projects. Use ProRes MOV if you need a higher-quality intermediate file for further editing.


Q2. Why does iMovie reject some MP4 or MOV files?

Because MP4 and MOV are only containers. If the internal video or audio codec is not supported, iMovie may still reject the file. Re-encode it to H.264 video and AAC audio, then try importing again.


Q3. Can iMovie import camera files?

Sometimes. iMovie may accept AVCHD and other camera recordings when imported from a complete camera archive, but loose clips, broken folder structures, or unsupported encodings may fail. Converting the footage to MP4/MOV is usually easier.


Q4. Can iMovie convert a DVD to MP4?

No. iMovie is a video editor, not a DVD ripper. You need to digitize the DVD with a DVD ripper first, then import the converted video into iMovie.


Q5. Will converting video for iMovie reduce quality?

Any re-encoding can change quality. To minimize loss, keep the original resolution and frame rate, use a reasonable bitrate or quality setting, and avoid converting the same file repeatedly.

In Conclusion

iMovie works best with MP4/MOV files encoded with H.264 video and AAC audio. When you cannot import a DVD, camera recording, downloaded video, or another local file, the quickest solution is to convert it to an iMovie-friendly format first. Use WonderFox HD Video Converter Factory Pro for regular videos on Windows, WonderFox DVD Ripper Pro for DVD sources, and HandBrake or an online converter for lighter Mac or browser-based tasks.
