This allows us to trim out the play button and frame the video just right in advance of the session.
We often use the Zoom screen sharing advanced features to share a portion of the screen when using this method. Video playback via screen sharing – Optimized for video clip Add a bit of music and everyone knows they are in the right place and properly connected. We often use this method to share a looped slideshow prior to an event start as participants join. Video playback via screen sharing – Not Optimizedīecause the images in the video file are actually still or use quick transitions, there is no need to optimize for video playback even though you are sharing a video file. We’ll break down the tech details, the benefits and use case best practices for you. Some methods will bypass screen sharing all together. Having all of these options at your disposal will allow you to ensure that your attendees are viewing the best-possible image quality at all times. Being aware of the following video playback options will help you decide which to use and when for best results. Is the video you are playing live action or is it a recording of slides or still images? Not all. Is this a big deal? Well, that depends on your use case and the content that you wish to share. Text, especially fine and dense text, will appear blurry and hard to read. Stepping down image quality in this way will result in less definition and a lower quality image.
ZOOM VIDEO QUALITY 720P
The 720p image has less than half of the visual information or pixels than the 1080p image. The same video, rendered at 1080p and 720p and played side-by-side on the same display will look considerably different. The resolution of an image or video determines its quality on screen. Further, CPU load is increased with the effort of downsampling an image to send which may add to quality issues in sending and viewing. They recommend that videos that are played through screen sharing be optimized with a resolution of 1080p to avoid quality loss from this downsampling to 720p. Zoom reviews this and some limitations in detail in their support article here. It takes the choppiness out of playback compared to not using this feature and sharing at 1080p, but it also loses half of the image quality resulting in an image that is not as sharp. Both options will step the screen sharing image quality down from 1080p to 720p, allowing for a much faster transfer of information and smoothing of the video playback via screen sharing. Zoom provides an option to share video via screen sharing using the option to “optimize for video clip” or by using the advanced function in screen sharing to present a video through a Zoom player. That’s a jump down from 1080p by over half. Internet connectivity and performance may cause this quality to drop down so that Zoom may continue to provide the content.īy comparison, Zoom’s video feed from your webcam is 720p (that’s 1280 width x 720 height = 921,600 pixels per image). This means that Zoom is capable of offering 1080 pixel lines of vertical resolution (1920 width x 1080 height = 2,073,600 pixels in a screen shared image). Let’s start with a foundational knowledge of Zoom screen sharing so that we can better understand the limitations. We’re going to share some tips and best practices with you so that you can play back videos like a pro.
More frequently, we hear from clients that want to playback video as a portion or primary content for their events.
