About the AVI to MOV conversion
A practical look at what happens during this conversion, what to expect from the output, and the trade-offs involved.
AVI and MOV are both video container formats, but they come from different ecosystems. AVI is a Microsoft format from 1992 — it's older, simpler, and broadly compatible but has known limitations around modern codecs and metadata. MOV is Apple's QuickTime format, which is essentially the predecessor of MP4 (the MP4 spec is based heavily on MOV). MOV is the native format for the Apple video pipeline: Final Cut Pro, iMovie, QuickTime Player, and macOS Photos all prefer MOV.
When the codecs inside the source AVI are compatible with what MOV can hold (H.264, H.265, ProRes, MJPEG, and a few others), the conversion is essentially a remux: the same encoded video and audio streams are repackaged into a MOV container without re-encoding. That preserves quality perfectly and runs very fast — you're not actually transcoding anything, just rewriting the container metadata. When the codecs aren't compatible (some older AVI files use codecs that MOV doesn't accept), a transcode is required, which takes longer and introduces a small amount of quality loss.
Audio tracks are preserved. If your AVI has stereo audio, the MOV will have stereo audio. If the AVI has a less common audio codec (some older AVIs use uncompressed PCM or older Microsoft codecs), the audio may be transcoded to AAC during conversion to make the resulting MOV reliably playable. Subtitle tracks, if present, transfer where the codec is compatible.
The most common reason to convert AVI to MOV is bringing legacy video into a modern Apple workflow. AVI was the dominant format for home video and screen recordings throughout the 1990s and 2000s; many archives of family videos, screen captures, and older productions exist as AVI files. Converting to MOV makes those files first-class citizens in Final Cut, iMovie, and QuickTime — they can be edited, trimmed, and re-exported without any of the legacy-format friction that AVI sometimes triggers.
Watch out
Some old AVI codecs aren't supported in MOV
AVI from the 1990s and early 2000s sometimes uses codecs (Indeo, Cinepak, certain DivX variants) that MOV containers don't accept. Those files require a transcode during conversion — the video is decoded from the legacy codec and re-encoded as H.264 (or another modern codec) for the MOV output. Quality is preserved as well as a transcode allows, but if you're working with a precious archival source, keep the original AVI as the master.
Pro tip
Choose ProRes if you're going into Final Cut
If your conversion is the first step before editing in Final Cut Pro or DaVinci Resolve, target ProRes 422 (or ProRes 422 HQ for higher-end work) inside the MOV instead of H.264. ProRes is a 'mezzanine' codec designed for editing — it's larger but much more efficient on the CPU during scrubbing, colour grading, and effect application. Edit in ProRes, then export the final cut to H.264 MP4 for delivery.
When not to convert
When MP4 is the safer choice
If you're not specifically targeting an Apple workflow, MP4 is more compatible than MOV — it plays everywhere, including Apple platforms. MOV is essentially Apple-flavoured MP4. Convert AVI to MP4 unless you have a specific reason to want the MOV container; the resulting file will work in Final Cut and QuickTime just like a MOV would, plus everywhere else.
Why Convert AVI to MOV?
Understand when and why this conversion makes sense for your workflow.
Converting AVI Video to QuickTime Video is often necessary to ensure playback compatibility across media players, operating systems, and streaming services. Video formats encode footage using different codecs, container structures, and compression techniques, each with distinct trade-offs between file size, quality, and support. From sharing videos online to preparing files for professional editing workflows, the right format makes a significant difference in how your content is experienced.
AVI Video has a known limitation: no native support for variable frame rate or modern streaming features. In contrast, QuickTime Video offers a key advantage: excellent codec support including Apple ProRes for professional editing. While AVI Video is commonly used for legacy video file storage and archival, QuickTime Video is better suited for professional video editing and production on apple platforms.
With MegaConvert, you can convert AVI to MOV online without installing software, preserving your video content accurately within the target format's specifications.

How to Convert AVI to MOV
Follow these simple steps to convert your file in seconds.
Upload your AVI video
Choose your .avi file using the file picker or drag it into the upload area. Video uploads can take a few seconds for short clips and longer for high-resolution footage; the progress bar shows upload status separately from conversion. Files up to 100 MB are supported.
Start the MOV conversion
Click convert. Where the video codec is compatible with QuickTime Video, the stream is repackaged without re-encoding to preserve original quality. Where re-encoding is required, we use industry-standard codec presets that balance file size against quality. Audio tracks are converted in parallel.
Wait for the video conversion to complete
Video conversions take longer than other file types because video data is much larger. A short clip might finish in 10 seconds; a 100 MB file may take a minute or two depending on whether re-encoding is required. The progress bar shows the percentage complete.
Download your .mov file
When the conversion finishes, click the download link to save the new QuickTime Video file to your computer. The file is yours — no watermarks, no expiration on the file itself, and no MegaConvert account is required to download it.
Tips for Converting AVI to MOV
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
AVI Video has a known limitation: no native support for variable frame rate or modern streaming features. QuickTime Video addresses this with a key advantage: excellent codec support including Apple ProRes for professional editing. Converting from AVI to MOV is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
AVI Video is most commonly used for legacy video file storage and archival, while QuickTime Video is the standard for professional video editing and production on apple platforms. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where AVI is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the MOV output
QuickTime Video has its own limitation worth understanding before you commit: historically less compatible on non-Apple platforms, though support has improved. After the conversion completes, open the MOV file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Avoid transcoding unless necessary
Every time you transcode (re-encode) a video, some quality is lost unless you use a lossless codec. If you only need to change the container format without changing the codec, use a remux (stream copy) operation instead of a full re-encode. This preserves original quality and is much faster.
