Screenshot and Video Recording

See system settings Screenshot and Video Recording for more options.

There are several ways to do screenshots:

  • Screenshot to PC
  • Screenshot to Device
  • Screenshot to Device Memory (only available in JS/REST API).

Three formats are available: BMP, PNG and JPG. The screenshot is performed on the device (not existing device screen), it will be done in native resolution, if you have high resolution (e.g. 4K) device screen, do not use BMP, it will take a long time to transfer large BMP data to PC (or take a long time to store). Use lossless PNG or JPG (with slider to set quality) to save space.

The screenshot can store in file or clipboard, file is stored in file path, for the clipboard, you can paste on graphics program such as "Paint".

For PC with high resolution screen (2K or above), capture native resolution will result in large file to be transferred to device. "Resize to 1080p" default option will treat screen as 1080p and resize accordingly.

For video recording, when video recording is turned on, a timer will appear, click red rectangle to stop recording. A few notes:

  • When in recording, the acceleration mode will be switched to HA2 automatically, to ensure low FPS (limit to maximum of 30 FPS) instead of 40-60 FPS in HA1, this will greatly reduce the size of MP4. After the recording stops, it will revert back to previous mode.
  • The video will be split into different segments, the segments are split by duration, when the duration is reached, it will create a new video file, this will limit the video file size. The video filename with segment is "<device name>-<date>-<time>-<segment no>.mp4", the segment number starts from 1.
  • Underneath of "Record Video" icon in device window menu item, there is a little arrow, when click, it will display a list of audio sources, microphone, line-in and THA, select the source, it will be mixed in the video.
