Here are some of the most common container formats: Audio One vital thing we have to mention before moving to our picks for the best video codecs is the difference between a codec and a container format.Ĭontainer format is a package or a wrapper that contains all the necessary metadata of a digital file, including an audio codec, video codec, and closed captioning. The Differences Between a Codec and a Container Format That means they will be much smoother and with higher frame rates. Without codecs, all digital media files would take dozens of times longer to download!Īlso, codecs optimize video files for playback. The reason you need a codec is simple - uncompressed audio and video files are massive! That makes it challenging to transport them, particularly over the internet.

Why do you need a video codec anyway? What are the best video codecs out there, and how do you choose the right one? These are just some of the questions we will answer in this article, so let’s get into it! In short, video encoding is a process of compressing video files to play smoothly like a video recording instead of a quick, laggy, slideshow of individual images. Video codecs play an integral role in video encoding, which is why almost anyone can create and consume videos nowadays. Do you know what happens behind the scenes of every video recording? Let us immediately tell you one thing - if it weren’t for video codecs, videos wouldn’t be so widely accessible! Many people worldwide consume video content daily, but few know just how complex and intricate video technology can be. If you use Scale to Fit or Scale to Fill, you can change the anchor position of the media file as well.Experts estimate that 82% of all internet traffic will consist of video by 2021, which shows how popular video has become nowadays. Once the Cue Inspector opens, click on the second tab (gear icon) and change the scale option.
Right-click on the media cue and select Media Properties. You can change the setting for any media cue in the Cue Inspector. For most looping backgrounds, any distortion that may occur wouldn't be noticable. If your media has defined objects (people, buildings, circles, etc) that will show distortion, you may not want to use this option. This may result in distortion of the image if it is a different aspect ratio than the screen. This option simply makes the image fit the screen with no regard to the aspect ratio. The aspect ratio of the media is maintained. As you can see below, the logo will be cut off on the top and bottom in order to fill the entire screen. If the image is a different aspect ratio, then cropping will occur on either the top and bottom or the left and right. Scale to Fill expands the image from the center point to fill the entire screen. In this sample, the image first reaches the top and bottom, resulting in pillar boxing. This may result in letter boxing (bars across the top and bottom) or pillar boxing (bars on the left and right). Scale to Fit expands the image from the center point until it hits two edges of the screen. The ProPresenter logo is a different aspect ratio, so it isn't going to fit properly on the screen. In each image, the box with the black outline represents a 16:9 screen. The easiest way to explain what each of these settings does is to simply show you. You can change these two defaults in Preferences under Advanced if you would like them to use different scaling behaviors. By default, Backgrounds use Stretch to Fill and Foregrounds use Scale to Fit.
All media in ProPresenter supports three scaling options: Scale to Fit, Scale to Fill, and Stretch to Fill.
