When Do You Need to Convert MOV to MP4?
MOV is what an iPhone and QuickTime produce, and it causes trouble outside the Apple world: some Android phones, Windows media players, video platforms and editing tools would rather have MP4. Converting MOV to MP4 usually fixes playback and upload problems in one step.
What Happens When You Convert MOV to MP4
ffmpeg reads the MOV and writes an MP4. The two are closely related, both descending from the same base container format, so this is often a lighter operation than it sounds and the video and audio streams inside are frequently the same codecs either way. Duration, resolution and frame rate are preserved. Where re-encoding is required, the file is processed rather than simply rewrapped, and that step can take a while on long or high resolution footage.
Worth knowing before you convert
This changes the container and encoding, not the content. There is no trimming, resizing or rotation, so a video shot sideways stays sideways unless the rotation flag already handles it.
About MOV and MP4
video/quicktime
MOV is a multimedia container developed by Apple and used primarily in macOS and iOS ecosystems. It supports high-quality codecs such as ProRes, making it popular in professional video production and editing workflows. While excellent for editing, MOV files are often larger than MP4 equivalents.
video/mp4
MP4 is the most widely supported video container format, designed to store video, audio, subtitles, and metadata. It commonly uses H.264 or H.265 codecs to balance quality and compression efficiency. MP4 works seamlessly across devices, browsers, and streaming platforms, making it the default choice for web and mobile video distribution.
Conversion Notes
Video conversion re-encodes both the video and audio streams to fit the target container and codec. Resolution, frame rate, and aspect ratio are preserved by default. If the source uses a codec not natively supported by MP4, a compatibility codec is chosen automatically. Conversion time scales with file duration and resolution — 4K files may take several minutes to process.

Not visibly in normal cases. MOV and MP4 are close relatives and commonly hold the same codecs, so the picture comes across intact.
