In order to play this AVI file, the PC used must be able to process frame to frame imagery at an average disk transfer rate of 186 MB/sec. The DownloadVideo© GUI then transcoded this source file and generated and uncompressed video packaged in the AVI format. Using the 6520 Inserter-Recorder and the DownloadVideo© GUI, ITS conducted a brief study about the effects of compression on a still shot taken from an HD video clip.Ī 15 second 1080/30 clip was recorded on the 6520 then downloaded to a PC via an Ethernet over our company LAN.

The DownloadVideo© GUI combines these external tools to render a software package that can download video from a 6520 via Ethernet, parse it and format it to a raw video file that may be played by our GUI and transcode it to AVI, MP4 or Windows Media Player formats. The 6520 Download Video kit also includes FFmpeg which is open source transcoding software that is also an underlying element of VLC players. The FFplay is used by nearly every VLC based player software package. Once an HD video clip is downloaded to a PC, the DownloadVideo© GUI permits you to play it using an included executable version of the open source FFplay function. The ITS 6520 records uncompressed HD-SDI video, play it back, view it frame by frame and play a subclip, but the actual video samples can be downloaded via Ethernet to a file using our 6520 Download Video GUI. For instance, you can reduce the size of your video by half while still maintaining quality by simply using HEVC (h.265) instead of AVC (h.264).This Technical Brief has been provided by our valued supplier ITS. The most common codecs for online video are AVC, HEVC, XviD, and AVI. You can shrink the size of your video file considerably by changing the codec. You can optimize video bitrate for smaller file size without compromising quality. You can manually cut out parts of the video using editing software or automatically by adjusting the bitrate. You can reduce video file size significantly by removing some unnecessary parts. For instance, changing the resolution from 1080 to 720 will cut the size of your footage by half while still having a good quality video. One of the easiest ways to compress video is by changing the resolution. You may already know by now that high-resolution videos take up a lot of storage space. Speaking of which, here are the different ways to compress video files. Therefore, compressing or reducing the size of your video files will, in most cases, involve the modification of any or all of these factors. The resolution, bitrate, and codecs all affect your video file size. The codec affects the size of your video significantly.

A portmanteau of the terms code and decode, a codec simply is a device or piece of software used to compress the video for storage and playback. A higher bitrate often translates to a better-looking video and a larger file size. In digital multimedia, bitrate refers to the amount of data encoded for a unit of time, usually referenced in megabits per second (Mbps) for video. The higher the resolution, the bigger the file. Resolution defines the amount of detail in the video.

Video resolution refers to the quantity of pixels in a video, usually represented via horizontal and vertical measurements such as 1920*1080 for full HD video. To understand how compression works, there are a few terms you need to understand. Unless your goal is achieving the highest resolution possible, having smaller video files is best for everyone. Video compression refers to the process of encoding a video in such a way that it uses less space than the original file and is easier to share across different devices and over the internet.Ĭompression reduces file size by eliminating redundant and non-functional data from the original video.

Depending on the frame rate, raw 1080p HD footage can consume more than 10 gigabytes of storage space per minute of video.

Keep reading to learn how to compress a video and the different video compression methods that you can use. Compressing your videos reduces bandwidth usage and file size, drastically improving the video creation and editing process. This is a problem that videographers, editors, and content creators face every day.Ĭompression is the most effective way to get around the frustrating limitations on email and hosting platforms.
Large video files can be a challenge when it comes to uploading and hosting. But like most videos we record these days, your footage turns out to be too large. Now you want to share it with your partners or perhaps get some input from the client.
