Snagit is supposed to record at 30 frames per second - why is my video showing less than 30 frames per second?
Only capture the necessary frames....
Snagit 13 and later offers three different options for video recording quality. Each quality setting captures at a different frame rate.
|Quality Setting||Recording Resolution||Capture Frame Rate (up to)|
|Low||1080p||Snagit 2018 / 13: 10 FPS|
|Low||4K||Snagit 2018 / 13: 10 FPS|
|Med||1080||Snagit 2018 / 13: 15 FPS|
|Med||4K||Snagit 2018: 15 FPS
Snagit 13: 10 FPS
|High||1080||Snagit 2018 / 13: 30 FPS|
|High||4K||Snagit 2018: 20 FPS
Snagit 13: 10 FPS
This means that Snagit is taking pictures (frames) of the screen X many times per second. However, if there is no change on the screen from one frame to the next, then that duplicate frame is not recorded at all (with exceptions for when audio is being recorded). For example, if an application window is recorded, but the window does not change at all, then there is no need to record additional frames for the same content.
Only capture content that is changing....
Another example is if only a small portion of the screen is changing. If only a portion of the screen is changing, then Snagit will only focus on that portion, rather than capture the entire duplicate frame.
For example, if recording a webinar where a speaker is talking - Snagit would concentrate on just recording the area of the screen that is moving. In this case, it would be the speakers mouth.
Variable capture frame rate...
Snagit uses variable frame rates to capture. This means that the frame rate is always changing to optimize performance. As a result, even if the High quality setting is chosen for a 1080p recording, the final video will not likely show as a constant 30 frame per second video. Instead it will vary throughout the video, up to 30 frames per second.
Why not just capture everything?
By utilizing this "smart" method of screen recording, Snagit is able to record high quality videos while maintaining very efficient video files (file size is smaller). This allows for faster saving, and faster sharing of content.
