The term lossy refers to the fact that information is lost when extra or redundant data is removed from the file. JPEG images, MP3 audio, and MPEG video formats are all examples of lossy compression techniques. Lossy compression creates a smaller file size but at the cost of reduced video quality, which may or may not be noticeable to viewers. There are two ways to compress videos-lossy and lossless. This process groups similar pixels together, greatly reducing the file size. In an uncompressed video, data is stored for every pixel in every frame.Ĭompression reviews the images, identifies repetitive or duplicate frames, and deletes the data for a non-essential frame, and replaces it with a reference for the other identical frame. To understand how this works, think of a video file as a collection of static images. Like bitrates, higher frame rates will create larger video files.Ĭompressing a video file’s information into a smaller space reduces the file size and lowers bandwidth transmission requirements. For example, a video shot at 30 FPS has 30 images in one second of footage. Frame rate: Typically measured in frames per second (FPS), the frame rate is the frequency at which images appear on the screen.Lower bitrates mean smaller files but the video itself will have reduced quality. ![]() Higher bitrates result in high-quality videos that have large file sizes. Bitrate: The measurement of how much information is transmitted at any given time.Videos with higher resolution use more pixels to capture the image but also create larger file sizes. Resolution:The dimensions of the videos (both length and width) in pixels.Factors that affect video file sizes include: The larger the video file, the longer it will take to upload or share the file to online platforms. Insufficient bandwidth will slow down the transfer process, and viewers may experience playback issues when trying to view larger video files. Uncompressed video files take up a lot of storage space and require a larger bandwidth to transfer the data. Video compression reduces the data used to encode video content. In addition to attachment size limits, large email attachments also consume the recipient’s storage space and bandwidth to download the file.įortunately, there are ways to compress a video to reduce its file size, lessen its storage requirements, and increase its transfer rate. This means that a video as short as one minute long is already too large to send over email. ![]() ![]() Gmail and Yahoo allow users to send up to 25 MB in attachments, while Microsoft (e.g., Outlook and Hotmail) limits attachments to 34 MB.Ī 1080p video requires 103 MB of storage for every minute of footage. While maximum attachment file sizes vary by service provider, in general, you cannot send an uncompressed video file in an email. For example, if you try to share a video via email, you may encounter an error message stating that the attachment exceeds the file size limitations. Sharing and storing that video, however, can be a bit trickier. From instructional webinars to animations, screen recordings and more, video content is an effective way to communicate information related to a company’s products or services.
