On an average video, if someone were to take 90 consecutive frames and spread them out they will see a lot elements that are pretty much identical. So content created that uses a FPS of 30 means there are 30 “still images” that will play for every second of video. Usually denoted as FPS (frames per second), each frame is a still image that when played in sequence creates a moving picture.

Starting at a high level, most probably realize that video content is made up of a series of frames. To understand this relation, one first needs to understand video frames. A keyframe is an important element, but really only part of a longer process that helps to reduce the bandwidth required for video. As someone matures as a broadcaster, it pays to understand elements in greater detail to learn why a process is done and also optimal settings.įor example, a keyframe is something a few broadcasters have seen mentioned before, or saw the setting in an encoder like Wirecast, without quite realizing what it is and how beneficial this process is for streaming. There are a lot of terms and aspects of streaming technology that can be taken for granted. Should someone use an “auto” keyframe setting?.What’s the best setting for a keyframe Interval?.Relationship between keyframes and bitrates.Choosing a keyframe interval at the encoder Level.What are b-frames and how do they differ from p-frames?.This article describes this process in detail, while also giving best practices and ideal encoder settings that you can apply for use with your live streaming platform. In particular, it overlooks a fascinating process called interframe, which involves keyframes and delta frames to intelligently compress content in a manner that is intended to go unnoticed.
This sells short, though, the complexity that actually goes into compressing video content.

Microsoft Office 365 ProPlus English (284).Under the area Target Output, we can click at the resolution that we want and then press the OK button. If we want to compress all the photos in the presentation we must uncheck the check box next to the command Apply Only To This Picture. Under the Compression Options area, if we want to change the resolution for the selected picture the command Apply Only To This Picture must be activated. Once selected the Compress Pictures window appears as we can see. Once the image is selected the Picture Tools is activated, and then on the Format Tab and in the area of the ribbon named Adjust we select the command Compress Pictures as shown below. The description of the post has been done with PowerPoint 2010.įirst we select the picture that we want to change the resolution for by clicking on it with our mouse as shown at the image below. The same procedure stands either if the image is inserted in a Word document or an Excel File. However, we can change the resolution of a picture in order to decrease the image size.īelow I will show how this can be done in PowerPoint. We all know that when we insert images, photographs (high-resolution images) in our documents, presentations the result of the size of the file is to be increased.
