Preview is the window that video from the source can be viewed. You can watch any source in the Preview Screen.
- If you have more than one encoder , you will see that sections appears on the preview window for each encoder as it seen below. You must check the Encoder(s) which you want to enable. After checking encoder(s) , selected encoder(s) appear(s) on the preview screen , unchecked encoder(s) couldn't display on the preview screen.
This button is used to take snaphot from current encoder at the time of encoding. Please see Snapshot to have detailed information about snapshot.
This button adjusts preview screen to Fullscreen mode. If you click this button , preview screen appears like this form as it seen below.
If you want to exit from fullscreen mode , you must click 
this button (which appears on the preview screen after you chose Fullscreen mode) or click "Esc" button from the keyboard.
- You can adjust preview aspect ratio from the preview screen as it seen below. There are four options for this as “No change”, 1:1, 5:4 and 16:9. “No change” means; show preview screen as default which is depend on the capture card. Other options will adjust the preview screen according to chosen ratio. These changes do not affect recordings. This is only for previewing.
- The Preview Screens can be divided to four different formats. These are free, v. tile, h. tile and best fit.
Free: In free mode you can replace the preview screens and adjust their size free.
Vertical Tile: The preview screens will be located vertically in Vertical Tile mode.
Horizontal Tile: The preview screens will be located horizontally in Horizontal Tile mode.
Best Fit: The Preview screens will be located in the Best fitting location.
- You can adjust preview screen size too. Preview screen size options are 50%, 100%, 200% and Fit size. Fit means size is adjusted smoothly by ingest.
- In preview screen, there are some values over each encoder. At every encoder’s top, encoder name is shown. At top right side, buffer bar is shown and it indicates the latency of ingest while encoding. If it gets higher than 100, the bar turns to yellow which means this situation is critical and encoding should be stopped. At the left side, Vumeter is show. At bottom right side, duration of current file is seen.
- Bottom bar of preview:
While not encoding, this bar is gray and duration shows 00:00:00:00 .
While encoding, this bar turns to red and duration time keeps increasing until encoding stops or pauses.
When encoding paused, bar turns to yellow and duration stops increasing and waits.
While encoding, if encoding gets split, encoding stops and starts to record over a new file that’s why duration resets and bar color which is red does not change.
