The Lync 2013 client for Windows was released almost a year ago with some changes to how calls and meetings are recorded. Now, based on analysis and customer feedback, the Lync team has calculated a new set of recording resolutions, frame rates and bitrate ranges to make recordings go even more smoothly.
“We aimed to increase the resolution of recordings yet also provide smart tradeoffs with recording size, so we landed on three different resolutions options: 480p (854x480 pixels), 720p (1280x720) and 1080p (1920x1080),” writes Tolga Kilicli on the Lync Team Blog.
“We also increased the frame rate from 10 to 15 frames per second – not quite movie quality, but sufficient to capture PowerPoint animations and document scrolling.”
Kilicli says that improved frame rate plus the resolution options were “designed to produce sufficiently high-quality recordings and yet allow users to pick their preferred balance between recording resolution and file size.”
For a one-hour recording using Windows 8, these are estimates of the file sizes: Using 480p resolution takes up about 150MB of space; at 720p, it’s 250MB; and at 1080p, it’s 400MB.
“For a meeting that did not have much content shared, or if file size is more important for you compared to readability of text or fine details on the content shared, you might want to consider the 480p resolution,” Kilicli writes.
But, if you want to view or present the recordings on a wall display or large-screen TV, and you have “multiple things being shared in addition to videos of participants (e.g. screen sharing), then the 1080p option will work much better.”
The 720p option “sits in the middle as the default choice and gives decent quality, decent file size, and decent resolution for most users.”
You can see how to change the resolution used for your recordings in the screenshot above. Go to the Lync Tools menu, then choose Options, and find the Recording tab.
