And it is also interesting to see that it is using a framerate of 58.66 fps, which is also a bit odd. The bit rate of the file is 5243 kb/s, which tells something about how large the file will be in the end. Another thing we can see here is that it is using a weird pixel format (1844×1160). mov file contains a video that is already compressed with H.264. The first line we want to look for is the one with information about the video content: Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv, bt709), 1844x1160, 5243 kb/s, 58.66 fps, 60 tbr, 6k There is quite a lot of information there, so we need to look for the important stuff.
That is why it is always smart to look at the content of your original file before converting it. But it will also (probably) re-compress the video. mp4 is as simple as typing this little command in a terminal: ffmpeg -i infile.mov outfile.mp4 Working in the terminal may be intimidating at first, but you will never look back once you get the hang of it.Ĭonverting a file from. If you haven’t tried it already, FFmpeg is a collection of tools for doing all sorts of audio/video manipulations in the terminal. The general rule is that you want to compress a file as few times as possible.įor all sorts of video conversion/compression jobs, I have ended up turning to FFmpeg. The file size may be smaller, but the quality may also be worse. That means that the video content will be altered. In most cases, you would end up with a lossy conversion. There are many ways of converting video files. That is why I would like to convert from one container format to another. But since the container is different, it may still be unplayable in certain software. In those cases, the inside of such files is identical to the content of a. avi files may contain H.264 video and AAC audio. The important thing to notice is that both. However, both H.264 and AAC can also be embedded in other containers, such as. These are both parts of the MPEG-4 standard and can be embedded in. The most common today is to use the H.264 format for video and AAC for audio. Also, here there are many different formats. The compression format denotes how the video data is organized on the inside of a container. For example, many web browsers are not able to play these formats natively. This is confusing and can also lead to various playback issues.

However, both Apple and Microsoft software (and others) still output other formats. Nowadays, there seems to a converge towards using MPEG containers and. mov format for QuickTime files and Microsoft used to use. The container is often what denotes the file suffix.
One of the confusing things about video files is that they have both a container and a compression format. In the following I will explain everything in a little more detail. If you came here to just see the solution, here you go: ffmpeg -i infile.mov -acodec copy -vcodec copy outfile.mp4 Here I will convert from a QuickTime (.mov) file to a standard MPEG-4 (.mp4), but the recipe should work between other formats too. In my ever-growing collection of smart FFmpeg tricks, here is a way of converting from one container format to another.
