Part 1. Why Convert MOV to MP4?

Changing MOV to MP4 format is simply because MP4 has better compatibility, smaller file size, and less playback, import, upload, etc. errors.

Reason 1. MOV vs MP4: MP4 Has Better Compatibility than MOV

MP4 is better than MOV in terms of compatibility. MP4 is internationally recognized and used as the most popular video format for iPhone, Android, tablet, PC, operating system, and media players, while MOV is mostly intended for Apple’s devices and software. That’s why you can’t play MOV on non-Apple devices like Blackberry, PDA, smartphone or PSP, and then you need to convert MOV file to MP4 format to solve not playing, choppy playback, or no sound problem caused by codec incompatibility.

Reason 2. MOV vs MP4: MP4 Format Has Smaller File Size

MOV is developed by Apple as a standard format that uses a proprietary compression algorithm, meant to offer remarkable footage with little loss of quality and minimal compression artifacts, which also makes it a go-to format for a variety of cameras and drones.

As the requirements for high-quality pictures become higher and higher, most camera producers let their cameras record videos in MOV format up to 4K. For example, as of now, iPhone can record MOV in H.265/H.264 up to 4K 2160p, and DJI supports capturing 4K Ultra HD footages in HEVC at up to 60fps. For sure, MP4 can also be encoded with HEVC/H.264 up to 4K, but MP4 are typically more compressed than MOV making it smaller in size and well suited for storage, transferring and uploads to video streaming sites like YouTube.

Reason 3. MOV to MP4 Conversion Solves Many Problems with MOV Files

MOV is supposed to go well with media player, video editor and more. However, the incompatible codec and 4K resolution make things trickier. You may get into trouble when processing MOV files, particularly with CPU-intensive 4K HEVC MOV files.

• Solve MOV video playback errors: Most often, Android phone and media player like Windows Media Player fails to recognize MOV file format. And due to codec incompatibility and 4K resolution, MOV playback is occasionally choppy or freezing, no sound, or video audio out of sync. For this, installing MOV codec pack or converting MOV to MP4 is a good solution.
• Solve MOV file import/edit errors: As the file type especially the inner codec is not supported by your device or software, MOV probably won’t be imported to iMovie, Premiere or Lightroom for editing. The other headache reported by some video buffs is frame-accuracy error or strange artifacts during MOV editing. So, editors also need to convert MOV file to MP4 format.
• Solve can’t upload or share MOV files: The large file size of MOV influences the smoothness of sharing and the speed of uploads, and the improper format or code like Apple ProRes in MOV even makes the upload fail. So, transcoding MOV to a friendlier format like MP4 and compressing MOV to a smaller file size help get rid of such problems.

Accordingly, for easier playback, sharing, storage, or uploading, you need to convert MOV to MP4 and compress large MOV footages to smaller sizes. And a reliable MOV to MP4 file converter, preferably retaining the highest possible quality, is required for the job.

6. Is MP4 better than MOV?

MOV not importing/not playing problems are flooded on the forum and many users require converting MOV to MP4. Some users think MP4 is a better format for shooting on the DJI Mavic, Phantom, iPhone, Canon/Nikon cameras, and other devices. MOV and MP4 are just container formats. In terms of quality and file size, MOV and MP4 are almost the same. However, MP4 is universally compatible. MOV format is friendlier in the Apple environment.

7. Is there quality loss during MOV to MP4 conversion?

Remuxing MOV container format to MP4 is a lossless process that directly takes the video and audio data from the MOV container to another container MP4. However, it decreases quality to transcode MOV videos to MP4. Transcoding is a lossy process of decoding and re-encoding a format to another, for example, HEVC is changed to H264. Transcoding includes changing the video and audio stream bit rate and size. So, using a right video converter like WinX HD Video Converter Deluxe supports remuxing MOV to MP4 without losing quality. Its built-in High-Quality Engine helps reserve 98% original quality - you can tell no difference between the source MOV video file and the output MP4 file.

8. Is video size reduced by converting MOV format to MP4?

The video file size remains the same after switching the MOV container format to MP4. Factors affecting video file size are bitrate and duration. To compress the MOV video file, you can lower down the video and audio bitrate and cut out unwanted parts of the video.

9. Can I convert MOV to MP4 by changing the file extension .mov to .mp4?

Changing the file extension may turn your MOV into an MP4 file. However, things could be more complicated. Most of time, the not playing, importing or uploading error is caused by codec incompatibility, CPU-intensive HEVC codec and 4K Ultra HD, bit rate, frame rate, and others. While changing the file extension can’t change the inner contents of a MOV container format and thus can’t solve corresponding errors.
