Video (4).mp4

MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. The only filename extension for MPEG-4 Part 14 files as defined by the specification is .mp4. MPEG-4 Part 14 (formally ISO/IEC 14496-14:2003) is a standard specified as a part of MPEG-4.

On a Windows-based PC, it is usually possible to play M4V files via the default Windows Media Player. There are many free players available, including the Apple QuickTime player. Google Drive supports playing M4V files directly from cloud storage. Another option is to change the file extension from .m4v to .mp4, which allows the file to be played on most standard MP4 media players.

MP4 is a similar container format that supports audio and visual data and complementary data like subtitles. MP4 is short for MPEG-4 Part 14. A wide range of devices and media players support the .mp4 extension. This format also enables online streaming. This file format is therefore popular for various video functions. However, MP4 files do not benefit from DRM protection, making them suitable for widely-shared or public media that can be exposed to anyone.

Another issue to consider when comparing the MP4 and M4V formats is compatibility, which is often a top priority for consumers. In a direct comparison of the number of programs and devices supporting each file format, it is clear that .mp4 is a much more widespread file extension. Both Mac and Windows devices and applications can read MP4 files.

If your file does not automatically open, you can download the free, cross-platform software VLC media player, follow the instructions to associate the program with the .mp4 file extension, and you should be able to open and play your files then.

The MPEG-2 successor is the MPEG-4 format. Mp4 files are designed for high HD picture quality with low storage capacity. The most common codec is the standard H.264. In rare cases, the codecs DivX and Xvid are used. MPEG-4 is widely used for HD-TV and Blu-Ray. On Apple, .mp4 files are usually found under the abbreviation .m4v. Videos published on the Internet usually have the .mp4 format.

Update from my further investigations:All my .mp4s are .x264 & AC3. I am on MACOS 10.14.6 (Mojave). In NC 17.x I could enjoy all my videos. With NC 18.x something changed. Thanks to @Sanook for pointing out to the standard of NC`s video player, which is .x264 & AAC.Now I made an overview, what does work, what does not.MP4 Matrix2016780 155 KB

MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio, but can also be used to store other data such as subtitles and still images. MP4 allows streaming over the Internet.The only official filename extension for MPEG-4 Part 14 files is .mp4, but many have other extensions, most commonly .m4a and .m4p.

When inspecting sample.mp4 file's binary data using any Hex Viewer, like Active@ Disk Editor we can see it starts with a signature ftyp (hex: 66 74 79 70) at offset 4, which defines QuickTime Container File Type.

Thanks for reaching out to the Apple Support Communities! I understand that you're having trouble saving .mp4 videos to your iPhone. Nice work isolating the issue to only occurring with the videos which were shot vertically.

In addition, MP4 can refer to a video file extension (.mp4) while MPEG4 cannot. Normally, when we say MP4 video, we're talking about a video ending in the file extension .mp4. .mp4 is the only filename extension for MPEG-4 Part 14. MPEG-4 files with audio and video generally use the standard .mp4 extension. Besides MPEG-4, .mp4 can also be the extension for files using H.264, H.265, and other video codec formats.

Almost all media players support MP4 container/format (MPEG-4). A rare few like RealPlayer only supports partial MPEG-4. If you try to play an .mts (mpeg2) video in iPhone, which somehow shows you "Unknown Video File", what is the solution? Surely, iPhone only supports .mp4, .mov and .m4v videos. So you can re-encode your video accordingly, meaning converting MTS to video formats like MP4 (mpeg4), MOV (mpeg4) or M4V (mpeg4) with a MP4 MPEG4 video converter.

Wondering why videos won't play on your iPhone? Chances are that your device doesn't support the file format of the video you want to watch. Your iPhone works only with .m4v, .mp4, and .mov file formats for videos. But if you've just downloaded a movie from the web, it's likely saved in either .avi or .mkv. The built-in apps like Photos and Files just won't play such a video. 041b061a72
