1. Export parameters of the line of captions:
   1. The Copy captions to separate files checkbox (1) enables saving the exported captions as a separate file with the .srt extension. The file with captions has the .srt extension and is saved to the specified folder for recording. Captions are exported as a separate line.

   2. The Combine captions into one track checkbox (2) enables saving captions of all kinds into one track (or one .srt file). If the checkbox is clear, then the timestamp and camera name captions are exported separately from the captions from the captions database.

      Info
      title Note
      Set both the Copy captions to separate files and the Combine captions into one track checkboxes in order to view all captions in Windows Media Player (WMP). This is due to the WMP feature: it does not allow selecting or switching the caption tracks (only enabling or disabling them). To ensure that the caption streams combined into one track don't overlap on the video during playback, configure one of the options to display them: set Set left alignment for each stream;. set Set different values of caption position for each stream using the X and Y coordinates;. set Set different alignment options for each stream. See Configuring caption streams. If you don't configure the display, captions can overlap during playback because their display areas overlap.

2. Text scroll parameters:
   1. The Enable automatic text scrolling checkbox (3) is used to limit the number of lines in captions overlaying the exported video.
   2. The maximum number of caption lines that can overlay the video is set in the Maximum lines to show field (4). If there are more lines in the captions that must be displayed in the video, then the lines are displayed in parts with a one-second interval between the parts.
3. The captions with timestamp and date can be added as a track or embedded over the video.
   

   Info
   title Note
   Captions with timestamps can be added to videos as a separate track in all modes except the following: without data conversion, with video compression (recompression) enabled. See Select the format and recompression for the exported file.

   
   
   1. Parameters of line of captions with timestamp and camera name:
      1. The Add line of captions with timestamp checkbox (5) enables overlaying a line of captions with the camera timestamp and date on the exported video. 
      2. The Add camera name checkbox (6) enables overlaying a line of captions with the camera name on the exported video.
      3. The Font button (7) opens the standard Windows OS window for setting the parameters of the caption fonts.
      4. The Color button (8) opens the standard Windows OS window for selecting the caption color.
      5. The Horizontal alignment and Vertical alignment drop-down lists (9) allow positioning of the timestamp, camera name, and other captions on the video.
   2. Parameters of the embedded captions:
      1. The Show camera name checkbox (10) enables the embedded captions with the camera name. These captions are always located in the bottom left corner on the exported video.

      2. The Show frame timestamp checkbox (11) enables the embedded captions with the frame timestamp. These captions are always located in the bottom right corner on the video.

         Info
         title Note
         Use FontCamNameHeight, FontCamTimeHeight, ExportFontAdaptive registry keys to set the embedded caption size (see Registry keys reference guide).

         
         

         Info
         title Note
         The Line of captions with timestamp group sets the standard format for all captions, including POS captions. These settings are applied if you don't set individual parameters for a specific line using the Configuring caption stream window.
