What is flashback?Any limitation to use this feature?
With flashback, you can buffer the contents in case you want to check the previous video and audio. And you can use the time slide bar to the buffered time to start your recording.
Green time is the render time.
Gray time is the live time.
Green time = Gray time when Timeshifting is started.
When you drag the time slide bar to previous section, Green time is earlier than gray time.
When you click the pause button, Green time is frozen and gray time is moving forward.
When you click the live button, the time slide bar will move to live. Green time = Gray time
Because the Timeshifting feature needs hard drive space and memory to buffer the video and audio, 8GB ram above and XXGB hard drive space is recommended.
