AirData Dashboard

This application will convert chosen fields from an AirData CSV (or Litchi flight log CSV) file into SRT format. The SRT file may be included in video playback using one of the following methods:

  • The SRT file may be named using the same basename as the corresponding video file. Then, an appropriate media player (such as VLC Media Player) can play the video file while displaying the SRT data as subtitles.
  • The SRT file may be imported into a video editor (such as Davinci Resolve) and aligned with the corresponding video file. Furthermore, the video editor may allow one to customize the position, size, color, and other attributes of the data displayed from the SRT file.
