![]() ![]() Experiment with both bit rates to find a balance between size and acceptable quality.įrame rate: this is the number of frames per second. Variable bit rates: Which can decrease quality if the bit rate does not change dynamically enough with the video. A variable bit rate changes depending on the amount of action on the screen, which will lead to smaller files. A constant bit rate stays the same throughout the video, which can lead to larger video files. Bit rates can be either Constant or Variable. Typically, this is measured in kilobits per second. The lower the quality of the compression, the more artifacts that will appear.īit/data rate – This is the amount of data that each second of video uses. Infrequent keyframes will leave lots of artifacts.Īrtifacts – These are blocky pieces of image that are the result of the keyframe not being updated correctly. Lots of keyframes will make the file large but higher quality. Your keyframe interval will have a large impact on the size of your finished file. This is the base frame for the next few frames of change. The codec will determine a keyframe every few frames. Learning these terms will help you make sense of the options you have while compressing a video.Ĭodec : This is a method that your computer uses to decide on the amount of change that occurs between frames. There are several key terms that you will come across constantly as you start compressing more videos. Compression stores the changes in the frames as opposed to storing entire frames. Because the images are so closely linked, not everything in the image moves from frame to frame. That means that every second, 24 or 30 still images are displayed to give the illusion of movement. Video is typically filmed with 24 or 30 frames per second. Any there any ways to reduce the video size without sacrificing the quality? Just follow the 5 ways below to compress your large video with no quality loss.īefore perform the video compression task, you should understand how compression works. It’s likely that you will have some videos or movies that’s to be uploaded to YouTube, unfortunately, you may find the file is far too large to upload. ![]()
