The more frames you have, the more detail you have, and the larger your file will become.Ī higher-resolution video has a larger display size and generally a larger file size. Still, your choice of file type can also impact the ratio between video length and file size.įrame rate or FPS (frame per second) affects video quality, with HD video using a minimum of 24 FPS. An MP4, for example, when converted to an FLV file, will be a larger file overall, as the codecs of an FLV are less efficient and result in less compression/file shrinkage.Ī video of one minute will be smaller than a video of one hour. Without getting too complex, some file types offer better codecs, that is, the process used to compress your video. Video types can impact the overall size and quality. The precise number of bytes needed for your file will depend on several factors, including: MP4s usually come up smaller than AVIs due to a better compression rate. So while an AVI and MP4, for example, are both file types/containers, they are not codecs in themselves. Containers are like envelopes that hold the codecs. No, an AVI is a container that dictates your video's file extension.

If you are using video editing software in Windows, chances are this is the codec it will use. WMV: Microsoft claims WMV provides better quality than MPEG-4.ProRes: A codec used in software such as Apple's iMovie, ProRes, as the name implies, gives fantastic color resolution.

MPEG: One of the most widely used codes, MPEG, and its derivatives, including MPEG-1 and MPEG-4, result in high-quality video playback even after compression.Sometimes you need to know which codec to choose, so it's helpful to know the following types of codec:

What you need to know is that, without codecs, your file size would be at least three to five times larger. If you need to convert a video's codec, you can use transcoding software such as Handbrake. Codecs usually work automatically within the program of your choice, so you shouldn't need to worry about them. They essentially shrink your file down for storage and then decompress them again when you're ready to view them.

What's a codec?Ĭodecs are the code used to compress your video. So, essentially, if your file is in the gigabyte range, you'll want to get it down to the megabytes. Generally, you'll see files measured in kilobytes, megabytes, gigabytes and terabytes: What's a byte?Ī byte is a unit of measurement used for digital files. Alternatively, you can upload your uncompressed video into Dropbox and share without worrying about compression. If the video is long, it will take a very long time to compress, so you can waste a lot of time if you export as the wrong file format. Most video editing programs will let you choose your resulting file format, including MP4, AVI, MOV, and WMV. These programs require you to open your video, usually by clicking 'open' or 'import.' Then, exporting converts them to a new file type.

Alternatively, you could send your video in a ZIP compressed file, but this will require your recipient to download it on their end.

Most video editing programs, such as iMovie for Mac or Windows Video Editor for Windows, come with a built-in video compressor. This is when things start getting 'pixely,' 'grainy,' and generally not viewable. You'll only start to see compression wreak havoc on display quality if you want to shrink a file down to a tiny file size while maintaining resolution.

Think about how a Hollywood movie goes from cinema screen size to a DVD, playing on any home TV without lag. To the human eye, this loss is hardly noticeable. Video compression occurs by removing repetitive images and sounds as determined by the codec algorithm. Depending on the original size, this quality loss may not be noticeable, but that all depends on how small you need your video file size. However, it usually means overall quality takes a hit. Essentially, compressing your video cuts a chunk off the size needed by your file. That means your video won't fit into your message, or your recipient can look forward to a lengthy download period on their end. Unfortunately, almost all file sharing methods, from email to instant messaging, have file size limits. Video compression is a way of shrinking your video file size. Compressing your videos solves this problem. Sharing high-quality videos between teams and clients can be frustrating since video files size are bulky at the best of times. Technology is a wonderful thing, but there are still some things that can make even the most tech-savvy person get a little anxious.
